Porsche stuck in the past? How otherwise to explain the commitment of the rearranget location on sports cars of this titled German company on its most famous coupe of the 911st series? The overall essence of the layout has not changed for decades. Initially, the original 911th model 356-series, as well as the pre-war model Käfer, was made in the rear-engine rear-wheel drive version. The engine suspended behind the rear axle.
In history, there were only two more modern exceptions to the rules, which, rather, could be called experiments of engineers on racing models: 911 GT1 of the late 1990s and current 911 RSR. At both models, the engine is located in the middle.
So, is the location of the engine behind the anachronism of past years or is there still sense? Most likely, there is no meaning in this - do not fools develop one of the best sports cars in the world. A detailed explanation that what, as always, will give from Engineering Explained, who released a short, but entertaining video telling history ... The history of physics and engineering.
The video explains several reasons why Porsche still does not leave the layout of the 911 layout, among which weight transfer in braking, weight transfer when accelerating and explaining the operation of the rear wheel drive in unique all-wheel drive vehicles.
It is worth noting that the ideal cars do not happen, as there are no only true designs of cars, rockets, airplanes and even toothbrushes. "Technyar" only sets out supported by knowledge "for" and "against" such a design and argues on the topic, and why still Porsche did not move away from their canons.
Positive sides:
Braking. Comparison (1.20 minute of video) two models. Porsche 911 and the second, front-engine sports model of the car, schematically depicted red. Both models rear-wheel drive.
The ravine at Porsche is 40% in front, 60% - rear. Running in any other front-engine rear-wheel drive car approximately corresponds to 55% on the front axle and 45% on the back.
When braking, 20% of the weight passes to the front axle. At the same time, the weakness of Ferdinand Porsche remains more balanced (in front - 60%, from behind - 40%) than any other car with a classic layout. Thus, the braking of the 911th will be more stable, more intense, the rear wheels when braking are involved by 15% more than that of other sports cars, less chances remains that the car will drive, even in turn.
The main task of any sports car is evenly distributed weight on all four wheels, and Porsche copes with it perfectly.
Acceleration. Here, Porsche also has a serious advantage. It is logical that with intensive acceleration, start from the place to the back axis should have the maximum weight as possible. Thus, slipping tires on the surface will be less. Less slipboard, more torque will not go to heating the environment, but to overclocking. In the rear-engine Porsche weight will be 15% more on the rear axle than a similar front-unit sports car. An extremely important factor, subject to the presence of high power under the hood.
Why is the full drive system on Porsche 911 - is it cool? Here everything is extremely simple. The mechanically all-wheel drive system consists of: sending power by semi-axes to rear wheels, cardan, multi-disc clutch with electronic control.
Technically, the distribution of torque and power can vary from 40% on the front axle to 95% - to the back. What does it give? Full feeling in controllability, like on a rear-wheel drive car. "But wait! - Exclaimment of the connoisseur, - other automakers do the same. For example, AUDI new models are also able to distribute power over the axes in a similar manner. " And it will be formally right.
Stuttgart. The six-cylinder Porsche's opposite engine is awarded the "Engine Year" premium. This year, the international jury was awarded the prestigious 2,7-liter engine of Boxster and Cayman car, stated in the engine category from 2.5 to three liters. "Excellent engine for a great car. This "heart" Porsche combines technical perfection, sports characteristics and impressive economy, "so justifies the decision of the jury Dean Slavic, which represents the magazine" Engine Technology International Magazine ". This British magazine presents awards for outstanding engines for 15 years. The jury also noted the elasticity, technical characteristics and smooth operation of the smallest in the volume of the Porsche opposite engine.
This sports engine with a reduced working volume is created on the basis of the 3.4-liter engine. In Cayman, it works with the DoppelkupPplung (PDK) gearbox and develops the power of 275 hp. (202 kW), consumed in the cycle of NEFZ 7.7 liters of fuel per 100 km (180 g / km CO2). In its liter power, component of 101.6 hp / l, this six-cylinder engine is superior to the magic sport engine
the limit is 100 hp per liter volume.
Thus, the Porsche's opposite engine has been the winner among the best engines in the world for the fourth time. In 2007, Porsche won in the category of engines from three to four liters, submitting a Porsche 911 Turbo force unit to the court. In 2008, the victory in the class of engines without limiting the working volume won a 3.6-liter opposite engine with a superior capacity of 480 hp In 2009, the 3.8-liter six-cylinder engine 911 Carrera S. The best engines of the year in various categories were determined by 87 authoritative journalists of specialized publications from 35 countries. In addition to the power, fuel consumption, technical characteristics and comfort, journalists were assessed and used promising technologies.
Advantages: Compact and lightweight, spinning to high revolutions and smooth in work - for 50 years
This year, Porsche 911 and a six-cylinder opposite engine note its 50th anniversary. The main advantages of the engine are flat shape, low weight and compactness. The six-cylinder opposite engine is characterized by smooth operation. It does not have the so-called free moments and forces. In addition, the opposite engines are very well suited in order to reduce the center of gravity of the car. This is also facilitated by the horizontally cylinders. And the lower the center of gravity is located, the sports will be the challenges of the car.
One of the most remarkable characteristics of six-cylinder Porsche's opposite engines was reduced fuel consumption compared to the engine power. The basis of this excellent efficiency is the overall concept taken from motor racing. This concept involves the use of lightweight structures, easy spinning to high revolutions and high specific power due to the improved gas exchange process.
It was the basic characteristics of these engines that caused the decision in favor of the opposite six-cylinder engine at the appearance of the first 911. As a result, a six-cylinder air-cooled opposite engine was developed, with an axial fan - due to the high speed of rotation and to ensure increased smooth operation - and high-location distribution shafts . For the operating volume of the engine, two liters were first selected with the possibility of a subsequent increase of up to 2.7 liters. At that time, none of the specialists of Porsche could even assume that the engine of this type in its basic form lasts until 1998 and that its working volume will increase to 3.8 liters.
World premiere of 1963: a two-liter engine with a capacity of 130 hp
During its global premiere at the international exhibition in Frankfurt am Main IAA in 1963, the first 911, called another 901, was equipped with a two-liter six-cylinder opposite engine with a capacity of 130 hp. at 6100 rpm. The success of this new sports car forced the Porsche company about a more powerful engine, and already in 1967 a 911 S debit with a 160 hp engine was held. at 6600 rpm. Soon after that, the base model received the designation 911 L,
And later - 911 E. Special pride in engineers then caused the fact that, despite the more powerful engine and a liter power of 90 hp, the service life of the force aggregate 911 S was not reduced.
911 took the robust position in the world market not only due to its powerful engine, but also due to progressive technologies. In 1968, for the first time for the US market, Porsche has released a sports car equipped with a low-toxicity engine. At the same time, Porsche managed to do this not to the detriment of the power and with the provision of almost the same comfort, as well as to fulfill the requirements of American laws to toxicity exhaust, namely, especially strict provisions operating in California. The decrease in toxicity was due to the removal of exhaust gases into the inlet system and in thermal actors. Porsche became the first European enterprise, where test stands were established for design work.
By the fall of 1968, Porsche began to produce a mechanical injection system of gasoline fuel with a six-ceramic pump. Together with the increase in the working volume of its engines, it increased their power and torque. In 1969, the six-cylinder engine first became 2.2 liters, and two years later - 2,4-liter. As a result, the power of the engines 911 s increased first to 180 hp, and then up to 190 hp In 1971, the compression ratio was lowered so that all 911 could drive around the world on gasoline with octane number 91. In close cooperation with Bosch Porsche, developed an improved system of permanent injection K-Jetronic, which for the first time began to be applied in 1972 in the designed For the US market models.
In 1974, the debut of the first serial sports car with a turbocharger 911 Turbo took place
In 1973, engines with a working volume of 2.7 liters, capable of working on non-determined gasoline with octane number of 91, began to be installed on a generation 911 models of 91. Thereby, the Porsche company reaffirmed once again that sports cars can be environmentally friendly. In 1974, the premiere of the legendary car was held: Porsche introduced 911 Turbo - the first serial sports car with a turbocharger. The company's engineers applied their rich experience in engines of racing cars when developing jets with a superior for serial cars. As the basis of the engine was taken by the power unit 911 Carrera RS 3.0 with a capacity of 260 hp, with a torque of 343 nm, an overclocking car to the maximum speed of more than 250 km / h.
Work on the further improvement of the six-cylinder engine was accompanied by a gradual increase in working volume and capacity using the most modern technologies for cleaning the exhaust gases. The first opposite engines with the neutralizer and the function of adjusting the exhaust gases are Porsche released in 1980. Three years later, she presented a new generation of atmospheric engines with a 3.2 liter working volume and with digital electronics. Now all the engines were prepared for operation on unleaded gasoline with octane number 91 - in many European countries of this fuel, then there was still no. However, when it appeared, it was possible to quickly adapt to new conditions. In 1988, Porsche once again improved the combustion processes and developed a cylinder head with two ignition candles per cylinder.
The top of the technical progress was the Opposite air-cooled air-cooled engine with a 3.8 liter working volume for the 993 series, which in the top model 1995 911 Carrera RS developed 300 hp The small series was released 911 GT2, developed on the basis of the experience gained with participation in the car racing. First, its 3.6-liter double turbocharge engine developed 430 hp, and the engine of the 1998 model range has already developed 450 hp. Two turbocharging systems was equipped and
911 Turbo. Equipped to the same system for monitoring the toxicity of exhaust Gas OBD II, he became a real world premiere. 408 hp engine It was developed based on a 3.6-liter atmospheric engine. However, he was subjected to such a comprehensive modification, which one can say that he had his own individual design.
In 1996, the world premiere of the first six-cylinder Porsche with water-cooled PORSCHE engine
A real breakthrough in the history of the creation of six-cylinder Porsche's opposite engines was the drive of a new Boxter model, whose world premiere was held in 1996. For the first time, Porsche applied a water-cooled power unit with a working capacity of 2.5 liters and a capacity of 204 hp. More not bound by restrictions caused by a former six-cylinder engine with air-cooled, the developers set the cylinder head with two camshafts and four valves per cylinder to a new power unit. A year later, a new 911 model range of 996 appeared, equipped with a water-cooled engine. This 3,4-liter power unit was significantly shorter than its predecessor and, above all, more flat. Its capacity was 300 hp, and its rotational speed was much higher compared to the atmospheric engine. In addition, there was an opportunity to adjust the camshafts on the inlet, and a system for adjusting the Variocam gas distribution phases. Two years later, this system was supplemented with the switching system of the valve stroke. Since then, she is called Variocam Plus. However, the most important characteristics remained unchanged: a six-cylinder engine, a crankshaft on seven supports, a two-mask flywheel and divided into the longitudinal direction of the engine. A new 911 turbo was also translated into water cooling. In 2000, a new 420 hp engine was installed on it. Work on the increase in working volume and capacity was obtained, as a result of which 3.6- and 3.8-liter 355 hp opposite engines appeared in the mid-2000s.
In 2008, 911 Carrera and 911 Carrera S received gasoline engines with direct injection developed from a pure sheet. With the same working volume they developed 345 hp and 385 hp From the same family, engines for Boxster and Cayman were taken. Reducing the working volume of engines to increase the efficiency of fuel consumption has become, starting from about 2008, the main task of engine developers. On the basis of the knowledge taken from various areas, Porsche has developed a new technique for the 911st model range of 991, which appeared in 2011: so the opposite engine in 911 Carrera with a capacity of 350 hp I received a working volume of 3.4 liters instead of the previous 3.6 liters. And the engine Carrera S with a capacity of 400 hp became 3.8-liter. Both models make it clear that the model range 991 was focused on the maximum efficiency in terms of fuel consumption: by the specific mass of 3.5 kilograms on hp, new
911 Carrera S is ahead of its main competitors. The highest figures 911 Carrera and 911 Carrera S are demonstrated by fuel consumption in the NEFZ cycle: in 911 Carrera it is 8.2 liters per 100 kilometers (194 g / km CO2), and
911 Carrera S It is 8.7 liters per 100 kilometers (205 g / km CO2) when each of them is working with Porsche Doppelkupplung gearbox.
Boxster and Cayman are presented in the segment of double roadster and coupe and have engines with similar technical specifications. For his 2.7-liter engines, they became winners in their category and were awarded the "Engine" award. The Boxster runs the engine with a capacity of 265 hp and consumes as much fuel as the power unit at Cayman with a similar power. Boxster S and Cayman S are equipped with a 3.4-liter engine, which develops 315 hp in the roadster, and in the sports coupe - 325 hp With the PDK gearbox, they are consumed in the NEFZ 8.0 l / 100 km cycle (188 g / km CO2).
All this company Porsche proves: a six-cylinder opposite engine is not yesterday. And an excellent base for the development of effective sports engines of the future.
Porsche Boxster / Cayman: Fuel consumption in the urban cycle of 12.2 - 10.6 l / 100 km; outside the city 6.9 - 5.9 l / 100 km; in a mixed cycle of 8.8 - 7.7 l / 100 km; CO2 emissions 206 - 180 g / km

It begins at the beginning of the 60s with a market output of the model 901. Since in the 20s of the 20th century Peugeot exceptional right to use the digital designation with zero in the names of models with zero in the middle only, the Germans had to change the name of the sports car at 911. Over the years, with each subsequent generation, the car has evolved in a technical plan, but the style still remained faithful to traditions.
Model 997 debuted in 2004 on the Frankfurt Motor Show, changing the controversial 996. Given the wishes of customers, the designers returned the pharmaces of the old style and shape. After the premiere, the versions of the vehicle optimized under certain conditions were gradually proposed - GT3, GT3 RS, TURBO GT2 and GT2 RS.
In 2009, Porsche 911 was upgraded. What changed? First of all, headlights, rear lights, bumper. In addition to stylistic transformations, the suspension was finalized, the engine is reinforced, and the Tiptronic S automatic transmission is replaced with a robotic double-grip PDK. Since 2012, it began to gradually refuse to produce individual versions of Porsche 911 997, replacing them with new generation 991.

In the case of Porsche 911, there has never been, no, we hope you will never have any compromises. This is a real sports car, like its engines. Every of them could be written a separate article, but so far we will present them in general.
Dynamics? Even nonspecialists know that Porsche leaves most cars on the traffic light. The basic version accelerates to 100 km / h in just 5 seconds, and the fastest Porsche 911 does it for a while just over 3 seconds. It is less, what is capable of Nissan GT-R. Even the weakest engines allow you to reach the maximum speed of 280 km / h, and the top versions are 320-330 km / h.
The most weak point of the Porsche engine is the intermediate bearing of the IMS shaft. Its destruction can lead to serious damage to the engine. Fortunately, in contrast to the predecessor, the problem is not so large and touched upon a small amount of cars. Symptoms: uneven operation of the engine and metal sawdust on the oil filter. There are also some cases of damage to cylinders. However, this time, the problem was touched by a small number of Porsche 911. However, relatively often it is necessary to change the failed coil and tensioner of the drive belt of the attachments of the attachments along with the pulley.
Nevertheless, in most cases, the engines practically do not deliver problems with regular maintenance. Mileage over 250,000 km without malfunctions is no exception. Depending on the style of driving, the average fuel consumption lies within 11-13 liters per 100 km.
Technical features
Porsche 911 engine is placed behind the rear axle. The drive depending on the modification can be both rear and complete. The choice was offered three gearboxes: the 6-speed mechanical, 5-speed automatic and 7-speed automated with double adhesion PDK. On the front axis of the MacPherson rack, and on the rear system of independent levers. Since the Security Institute Euroncap did not check this car, the level of its safety is unknown.
Typical malfunctions
From one of the views of Porsche 911, many potential buyers lose their heads. However, the choice of used car of this kind requires a cold head and attentiveness. Otherwise, you can get to the mini slow motion, which will rapidly empty your wallet or, even worse, will drive into debts.
What should I pay attention to? First of all, on the clutch and drive shafts. No strength steering tips and thrust, but these are non-serious defects. It is also necessary to carefully examine the engine and transmission for the subject, especially around the main axis of the RMS (the rear seal of the crankshaft). In addition, oil leaks are found through oil cooler (weakens the mount) and problems with the cooling system (cracking of the nozzles and the failure of the pump).
Inspecting the car on the lift, pay attention to the state of the silent blocks of the rear suspension. Since the engine is behind, it is this part of the chassis subjected to more rapid wear. Monitoring the status of springs and shock absorbers - another mandatory checkpoint.
What else can refuse? For example, the header of the audio system that stops returning the discs. Often, Porsche 911 owners complain about noise from speakers. Most often, the reason for this is a faulty amplifier. A rather unpleasant problem is the flowing hatch on the roof. Sometimes stopped functioning the retractable cup holders or internal door handles, but these are trivia.
Conclusion
Porsche 911 997, although he managed to take a little in large Russian cities, but still remains the object of the rehabils of many motorists and not only. When choosing and buying a car, it is not necessary to completely surrender to emotions. Careful check is very important. Otherwise, you will be forced to regularly visit car services.
In terms of reliability, sports car is quite stable. According to the results of the TUV inspections, the technical condition of the car is significantly better than comparable models of the same age. The body never has problems with rust due to galvanized. Avoid instances imported from the United States. Often they are carelessly restored after the accident.
By purchasing Porsche 911, you must be prepared for high cost of operation. While the main components are not too expensive, you will have to relatively often travel to gas stations and regularly change tires, brake discs and pads.

History of development
The emblem of the company is a coat of arms that carry the following information: Red-black stripes and deer horns are the symbols of the German lands of Baden-Württemberg (the capital of Baden-Württemberg - the city of Stuttgart), and the inscription "Porsche" and the Garzing stallion in the center of the emblem remind of That native to the stamp Stuttgart was founded as an equestrian farm in 950. For the first time, this logo appeared in 1952, when Mark entered the US market for better recognition. Prior to that, on the hoods of the model 356, "Porsche" was simply inscription.
1931-1948: from ideas for serial production
By the time of the release of the first car under his own name, Ferdinand Porsche managed to accumulate a considerable experience.
In 1931, an enterprise Dr. ing. h. c. F. Porsche Gmbh.The founder and leader of which he was, has already managed to work on such projects as the 16-cylinder racing auto union and "beetle", which became one of the best-selling cars in history.
In 1939, on the eve of World War II, the very first Porsche 64 was developed, in which the features of the future model Porsche 356 were already guessed. For the construction of this copy, Ferdinand Porsche used many components from the famous "Beetle".
Ferdinand Porsche junior was the successor of his father. Having received the education and the first skills of independent work, he moves to Stuttgart to work in the company just created by his father.
During the second global firm, the company was engaged in the release of military products - pile cars and amphibians. Porsche also participated in the development of tiger tanks.
1948-1965: First Steps
Since the late 1945 year, when his father was imprisoned in France, Ferdinand Jr. suffered a family business to the Austrian city of Gmünd, and also headed the production on his own.
Together with Karl, Raba Ferdinand assembled the Porsche 356 prototype and began the preparation of the model for its serial production. In June 1948, this instance was certified for general roads. Like nine years ago, units from VW Beetle were again used.
The first serial cars had a fundamental difference - the engine was transferred for the rear axle, which made it possible to reduce the cost of production and free the space for two additional places in the cabin.
Motor device Porsche
Engine components
The internal combustion engine is an engine that converts chemical energy into the mechanical energy of motion.
To create kinetic energy by burning fuel, a comprehensive interaction of many mechanical components is required.
Row Engine
The cylinders in the row engine are arranged each other, that is, in a row. This is the most frequently used engine configuration of the engine.
Benefits:
- simple design
- economical production
- high smoothness
Disadvantages:
- takes more space
- highly located center of gravity
Opposite Engine
The cylinders in the opposite engine are located against each other and slightly shifted relative to each other.
Benefits:
- especially flat and short design
- reduced center of gravity
- high smoothness
Disadvantages:
- complex design with a large number of components
V-engine
The cylinders in the V-shaped engine are grouped into two rows, located at an angle of 60 °-90 ° to each other. However, an angle can also be 180 °. The difference between the V-shaped engine with the location of the cylinders at an angle of 180 ° and the opposite engine is that in the opposite engine each connecting rod is located on a separate shoin of the crankshaft. In the V-shaped engine with the location of the cylinders at an angle of 180 °, one connecting rod shade is divided by two rods, respectively.
Benefits:
- little constructive length
- high smoothness
- reduced center of gravity
Engine Vr.
Benefits:
- combination of a narrow shape of a row engine with a short design of the V-engine
Disadvantages:
- uneven length of intake and release tact
W-shaped engine
In the classic W-shaped engine, three rows are located in the form of the letter "W". Corners between cylinders are less than 90 °.
A special form of a W-shaped engine is the VR-shaped engine: with the engine type, four rows of cylinders are located in two rows. The location of the cylinders in a row coincides with the location of the cylinders in the VR engine, and both rows of cylinders are located to each other as in the V-shaped engine.
Benefits:
Porsche 356.
"Porsche-356" was first equipped with a modified 4-cylinder engine of air cooling from the Volkswagen car and had an open body. For a better mass distribution along the axes on the prototype, Ferdinand Porsche has established a power unit within the chassis, but the production has begun the option with its rear arrangement, which made it possible to increase the passenger compartment capacity. The first series "356" had a body of a coupe from aluminum panels and was manufactured in the Austrian town of Gmünde, so known as "Porsche-Gmünde". To declare then a little-known brand, several cars of the "356" series participated in races and achieved good results. The usual road "Porsche-356" could be purchased at a relatively low price, so the demand for the sports car turned out to be huge.
To satisfy him, Porsche translated production to Stuttgart, where "Porsche-356" began to produce with cheaper steel bodies. For serial machines, a 4-cylinder opposite engine was used with a working volume of 1131 cm 3, also borrowed from Volkswagen. Later, "Porsche" reduced the volume of the motor to 1086 cm 3, while simultaneously changing the shape of the camshaft camshafts and setting two carburetors with a falling flow. So the power of the basic motor in 25 hp At 3000 rpm was raised to 40 hp. At 4000 rpm, while the speed of the machine increased to 129 km / h. Then the "356" series was equipped with engines with a working volume of 1286; 1488 and 1582 cm 3 with a capacity of up to 115 hp
The first German option "Porsche-356" was a coupe, a convertible appeared with a soft riding or with a rigid removable roof, as well as a sports "speedster" (Speedster). The latter became the most interesting and rare model. It was first introduced in 1954, but after 2 years the production was turned over, selling 4922 copies. "Porsche-356" was also produced in the version of the "Carrera" with an aluminum body coupe and a forced engine with a working volume of 1582 cm 3 with two camshafts, which made it possible to develop speed up to 200 km / h

Porsche 914.
In the late 1960s, Porsche began cooperation with Volkswagen, hoping to create a cheap vehicle version. The result was "Porsche 914". It was a lightweight double car with a central location engine, first introduced in 1969 on the Frankfurt Motor Show. Buyers could choose one of two versions of air cooling engines: 4-cylinder "Volkswagen" or 6-cylinder "Porsche 911". The first version of "914/4" was sold under the Volkswagen brand, the second, "914/6", - "Porsche". Although the "914" model was equipped with a fairly perfect 6-cylinder engine, it was not recognized by "the real" Porsche ", and a non-fried rectangular body caused little enthusiasm. Sales was so insignificant that after 1975 only the "Volkswagen" option was left in the program, which was offered with the engines of 1756 and 1971 cm 3.

Porsche 911 turbo
At the Paris Salon of 1974, Porsche showed a sports car, which eclipsed all other exhibits. It was "Porsche 911 turbo" with a 2,6 liter engine with a capacity of 260 hp, equipped with a tour-bonadzv. He accelerates up to 100 km / h in less than 5.5 s, which for that time was a very good indicator even for sports cars. The body was distinguished by characteristic wide posterior wings and massive spoilers. Over the next years, Porsche-911 turbo has repeatedly modernized, and the engine power gradually grew. The next generation machine was equipped with a 3-liter engine, and since 1984, the working volume increased to 3.3 liters. At the same time, the capacity has increased from 270 to 300 hp, and in 1991 - up to 320 hp Since 1992, the new "turbo-3.6" was brought by an engine with a capacity of 360 hp, which since 1996 increased to 408 hp. Since 1997, the Motor "Porsche 911 turbo-S" develops the capacity of 450 hp The car reaches the maximum speed of 300 km / h.

At first she was equipped with a 8-cylinder V-engine in 4474 cm 3 of liquid cooling with a capacity of 240 hp The five-speed gearbox was placed in one block with the main transmission. The car possessed good dynamic qualities. However, for the machine of this class they were quite ordinary. Two years later, the "928s" modification was appeared with a motor in 4664 cm 3, which has already developed 300 hp. In 1983, another, more comfortable modification with a motor elevated to 310 hp appeared. Power. For a better sale in the US, the car has become completed with an automatic 4-speed gearbox. "Porsche 968" was characterized by excellent sketch qualities, which, not least, was explained by the special kinematics of the rear suspension type "Transxl" (Transaxle). Despite the mediocre body aerodynamics, the latest modification with the engine in 310 hp Developed speed up to 255 km / h and possessed good dynamics. From space up to 100 km / h, it accelerated for 6.2 s (with a manual transmission).

Porsche 968.
"Porsche 968" is a direct heir model "944". This car appeared in 1991. The firm once again made an attempt to create a fairly cheap car. Structurally, "968" was slightly different from the predecessor "944" and used a number of nodes and parts from Volkswagen serial models and Audi (AUDI). The power unit was chosen a 4-cylinder engine with a working volume of 2990 cm 3, which was equipped with balancing shafts to increase the smoothness of the work. Its capacity was 240 hp, and on "968 turbo-s", equipped with turbocharging, - 305 hp Nevertheless, this as a whole is a good car turned out to be overly expensive. He lost a large number of buyers, which was originally designed.

Porsche Bister
When in 1993 the prototype "Porsche Bister" was first introduced to review the public, they immediately saw the promising concept of the company for the next decade. After 3 years, the prototype changed the serial "Baster", which immediately became a car bestseller. About the relationship of "Boxer" with the legendary "Porsche 911" they say the characteristic lines of the front and a lower back of the rear, the rest of them are not repeated.
The body acquired two side air intake, the individual, not fused into a single block appeared behind the unusual form. At the "Baster" (for the first time on the rear-engine machines), an engine with liquid cooling is installed. The new opposite 24-valve "six" with two camshafts in the cylinder heads has a working volume of 2.5 liters and is located longitudinally in the central part of the chassis in front of the rear axle, which provides a low location of the center of gravity and high stability.
The "Baster" is equipped with a 5-speed mechanical or automatic transmission type "Tittronic" (Tiptronic), in which two switching modes are provided: automatic or manual. In the latter case, the gear shift is carried out using a special buttons ("plus" and "minus") located on the steering wheel. Material top of the "Boxer" with the help of electric drives is laid in just 11 s Special compartment behind the seats. By request, you can install the original hard removable top, which gives "Boxer" a specific appearance.

DEVELOPMENT PROSPECTS
The automotive industry is an area where a hydrogen engine can be widely used in the future. Water, railway transport, aviation, as well as various auxiliary special equipment can use the strength settings of this type.
Interest in the introduction of hydrogen engines technology is shown both subsidiaries and large autoconcens (BMW, Volskwagen, Toyota, GM, Daimler AG and others). Already on the roads you can meet not only experienced samples, but also the full representatives of the model range, leading to movement with hydrogen. BMW 750i Hydrogen, Honda FSX, Toyota Mirai and many other models have perfectly proven themselves during road testing. Unfortunately, the high cost of hydrogen, the lack of infrastructure of filling stations, as well as a sufficient number of qualified employees, repair and maintenance equipment does not allow to run such cars into mass production. Optimization of the entire cycle use of rash gas is the initial task of the area of \u200b\u200bthe development of hydrogen energy.
Idea 911.
More details
Ferry Porsche and his son Ferdinand Alexander created a model 911 - an icon of a sports car, which for more than 50 years causes an incredible delight. The secret of success: a harmonious combination of confusing time design and unique - as our engineers say - layouts. The planting formula 2 + 2 is an ideal solution for a purebred compact sports car, which also fully meets the requirements of everyday use. The compact engine is located in the rear, which contributes to an excellent thrust and determines that the inimitable feeling that is born from a man driving 911. Since 1963, we have been working on making 911 even more perfect. And we have never been so close to our goal.
The eighth generation of 911 embodies all the best qualities of its predecessors and thereby reflects both respect for traditions and aspiration in the future. Silhouette - cult. Design - without failure. Technique - born on racing routes and always running one step ahead. The result was 911 in his most beautiful and modern performance. With a multitude of historical references and at the same time showing the future of the sports car. Thus, 911 becomes a car out of time.
911.
Out of time.
Design
More details
To describe 911, a single line is sufficient: the so-called Flyline passing along a long low hood, steeply climbing windshield and smoothly lowering roof. It was a characteristic element of the ancestor of all 911 more than 50 years ago and finds its extremely modern embodiment in the current 911.
Acquaintance with the design of 911 is best to start where his heart beats - the opposite engine. The powerful rear of a large extent determines the vigorous proportions 911. Its direct horizontal lines differ clarity and accuracy, emphasizing the laconicity of the car design and the concentration on the most important.
Salon
More details
A good design must comply with the requirements of the future, as well as the technique. Therefore, when creating a salon 911, designers went new ways, remembering his former strengths and complementing with new features. Principle: Analog accuracy in combination with digital integration - and, as always, with a maximum orientation on the driver.
The horizontal orientation of the cabin is attracted. All major controls are located in close proximity to the left and right of the multifunctional sports steering wheel. And thus in close proximity to the driver. This principle was characteristic of the first three generations of 911 and allowed to create a clear, lightweight interior architecture and ensure high management comfort.
Right before the driver's eyes, there is a dashboard with an analog tachometer in the center. On the left and right of it are two 7-inch high resolution display. At the virtual devices of these displays, important information about the car is displayed. Near the dashboard is a high-resolution touchscreen display with a diagonal of 10.9 inches, which is part of the siteMunication Management site (PCM).

Engines models 911 are created on the concept of teturbo. Among the outstanding qualities of these aggregates is the ability to develop high speeds, extremely sensitive responses and an impressive maximum torque, which is achieved by low revolutions. In other words, the brilliant technical characteristics that anyone will be admirable.
Turbocharger
The engines have two supercharger, one per each series of cylinders, as well as a boost air cooling system. The latter is an important part of the turbochargedwood system operating on the exhaust gases. It greatly contributes to the increase in power and at the same time reducing harmful emissions. Both indencing air coolers changed places with air filter. If earlier they were located on the sides in the rear wings, now the intercolers are placed in the middle right above the engine in the center under the grille of the back cover. This location allows you to improve the supply of cooling air and its removal. As a result, a significant increase in the efficiency.
For models, not only an increase in the power and engineering engine is characterized. His supports are shifted closer to the middle of the car. It seems that this is a completely insignificant change, but in fact it provides great advantages: the engine gets a tighter mount that significant increases stability. Vibrations are reduced, and the comfort of movement, on the contrary, increases.
Active air dampers
Solve the task of reducing fuel consumption in everyday life and the achievement of maximum results on the racing track helps active air dampers in the front air intakes. The flaps are automatically closed while driving and reduce the coefficient of aerodynamic resistance. If necessary, as well as in Sport, Sport Plus or PSM Sport modes, they open and contribute to the optimal cooling of the engine. Thus, the cooling air is supplied only in a quantity that is really necessary. Effective solution. And besides smart.
AUTO START STOP FUNCTION
The AUTO START STOP function turns off the engine at a speed of less than 7 km / h and slowing the average intensity. For example, when you rolled up to the traffic light. As soon as you release the brake pedal and press the accelerator pedal, the engine starts again - quickly and conveniently.
Sports exhaust system
Sports exhaust system provides an impressive resonance and an intense sports sound, typical for 911. It has a central end of the silencer, from which two exhaust pipes located on the sides of the body come out. These unique design pipes are offered from stainless steel silver or black.

8-speed Porsche DoppelkupplUNG gearbox (PDK)
Improved 8-speed Porsche Doppelkupplung (PDK) gearbox (PDK) provides very fast - literally for milliseconds - shifting gear without interrupting traction. Compared to the last generation, the 8-speed PDK offers significantly more opportunities to ensure excellent comfort, high dynamics and impressive economy.
PDK consists of two gearboxes mounted in one case. Two clips bind alternately both transmissions through two separate shafts with the engine. The torque from the engine is always transmitted through one of the two gearbox modules and one clutch, while the next transmission is already included in the second module. When changing the steps, the opening of one clutch and simultaneous closure of the other are performed. As a result, a very fast gear shift is achieved without interrupting traction, that is, the setting is very sporty. It is felt primarily on transmissions from the 1st to 6th, which have sports gear ratios, and the maximum speed is achieved on the 6th gear.
And efficiency? Also high. Due to the additional eighth stage, it is possible to select optimal gear ratios for two rising gears (7th and 8th), as well as optimally agree on them from the 6th transmission. As a result, the frequency of rotation is reduced, including at high speeds. It increases efficiency and comfort on long-distance travel.
Porsche Traction Management (PTM)
An important component of all all-wheel drive models 911: Porsche Traction Management (PTM) system. The electronic-controlled multid-wide coupling included in PTM optimally redistributes the torque between the rear axle with constant drive and the front axle. Continuous control of movement conditions allows you to respond to the occurrence of various situations. Sensors, among other things, control the frequency of rotation of all 4 wheels, longitudinal and transverse acceleration and angle of rotation of the steering wheel. If, for example, when overclocked, the rear wheels begin to buck, a multi-disc clutch sends a greater torque on the front wheels.
So the PTM system in collaboration with Porsche Stability Management (PSM) in any situation ensures proper redistribution of the torque for optimal traction and especially harmonious chassis in limit modes.
Porsche Torque Vectoring Plus (PTV Plus)
The system for increasing the dynamics of movement and stability uses controlled rear wheel drive, as well as the locking of the rear differential. With a dynamic style driving during the rotation of the steering wheel, the rear inner wheel is slightly slowed down. As a result, a larger moment comes to the outer wheel, and the car receives an additional impulse, "refueling" it in turn. This allows you to more confidently and dynamically pass the devices.
The locking of the rear differential is carried out with the help of electronics, and the redistribution of the torque is proceedable. Thus, along with the Porsche Stability Management (PSM), this system optimally implements its advantages to ensure sustainability, including on roads with different clutch coefficients, as well as in the rain and snow.
Result for the driver? High speed stability and outstanding traction. Exemplary maneuverability at any speeds - with balanced reactions to shift the load and accurate controllability. What else? Maximum pleasure on turns.

Porsche Active Suspension Management (PASM)
PASM is an electronic shock absorber system. It is actively and continuously adjusting depreciation efforts on each wheel depending on the state of the road and driving style. Thus, the system reduces the batch of the body and increases comfort with a greater dynamics of movement.
PASM has two positions that can be selected with a button over the central console: in normal mode, the system sets sports and comfortable adjustment of shock absorbers, and in sports mode - rigid.
New valves provide a wide range of regulation and accuracy of changes in depreciation. In addition, everything happens much faster. In addition, high depreciation force can be used even at low speeds. Moreover, with a tangible result: more stability, more comfort, and above all more sport style in any conditions of movement.
Porsche Stability Management (PSM)
Porsche Stability Management (PSM) is an automatic car stabilization system in limit dynamic modes. Sensors are constantly monitoring the direction of movement, speed, turning relative to the vertical axis and transverse acceleration.
On this basis, PSM calculates the actual direction of movement and initiates targeted slow motion of individual wheels so that the car does not deviate from the desired trajectory. When accelerating on roads with different clutch coefficients, the PSM improves the traction force using the interclapion differential blocking imitation system (ABD) and the anti-slip system (ASR). For high resistance and safety of movement, as well as for exceptional maneuverability.
Rear Wheel Management System
The rear wheel control system equally increases maneuverability and suitability to the conditions of everyday use. This system significantly improves handling while simultaneously increasing stability.
Advantage in everyday use: at low speeds, the system rotates the rear wheels in the antiphase with the front. This allows you to virtually reduce the wheelbase. As a result, the diameter of the reversal is reduced, the passage of turns is carried out more dynamically, and parking becomes significantly easier.
Advantage in a sports manner driving: At high speeds, the system rotates the rear wheels in one direction with the front. Thanks to the virtual increase in the wheelbase, the speed is improved, and the simultaneous turn of the front and rear wheels contributes to greater maneuverability.
Front Lift System
The front part lifting system allows you to increase the ground clearance on the front axle. The rise is carried out at a height of up to 40 mm at a speed of no more than 35 km / h. The system contributes to the fact that border stones, ramps and entrances to the garages cease to be an insurmountable obstacle to you.
Porsche Dynamic Chassis Control (PDCC)
PDCC is a system of active counteraction to rolls. On the turn, it minimizes the tilt of the body. In addition, it reduces the rush of the car on the wavy surface. As a result, the system improves the dynamics, contributes to neutral turning and increases the level of comfort - at any speed.
Torkemose

Slow down to relax and at least for a moment to forget about the desire for high results. It is not in our style. When our engineers talk about a slowdown, then everything should occur extremely quickly.
The brake sizes are selected according to the power of models 911. Models 911 Carrera in front and rear use 4-piston aluminum monoblock fixed calipers with black anodization. The diameter of the brake discs: 330 mm on both axes. Models 911 Carrera S are equipped with red 6-piston aluminum monoblock fixed calipers on the front wheels and 4-piston aluminum monoblock fixed calipers on the rear. Front and rear brake discs have a diameter of 350 mm. For high brake power and reliability.
Brake System Porsche Ceramic Composite Brake (PCCB)
Tested in motor racing: optional ceramic brakes Porsche Ceramic Composite Brake (PCCB). In 911 perforated ceramic PCCB brake discs have a diameter of 410 mm in front and 390 mm rear - for even higher braking power. The PCCB includes yellow 6-piston aluminum monoblock fixed calipers on the front axle and 4-piston aluminum monoblock fixed calipers on the back. They provide a much higher and primarily constant pressure in the system when slowing.
Especially at high load, favorable conditions are created for a short brake path. In addition, security is increasing when braking with high speeds, as PCCB is highly resistant to the loss of efficiency during overheating. Another advantage of the ceramic brake system is the low mass of brake discs. They are about 50% easier for cast-iron similar to design and sizes. As a result, unsappressible masses are reduced, which improves the adhesion with the road, comfort and smooth movement - primarily on the uneven surface. Also on a higher level of maneuverability and car handling.
If for 70 years of the history of the creation of sports cars, we learned something, so this ability to confidently go to your own way. Therefore, the wheels and tires on the rear axle have become not only wider, but also more than on the front axle. While the wider contact spot improves the dynamics, the increased diameter of the rear wheels contributes to greater stability and comfort.
In the basic configuration, the 911 carrera model is equipped with 19- / 20-inch Carrera wheels with 5 dual knitting needles, and the model S - 20- / 21-inch Wheels of Carrera S with 10 knitting. Material: Of course, light alloy. Design: Sports-classic. Not improved time. Do you want even more dynamicity? Filigree? Or do you like discs in body color? The order offers a variety of 20- / 21-inch wheels in various versions.

Sport mode
The Sport button allows you to choose between a comfortable and sports car setup. As a result of one pressing the button, the electronic engine control system makes his responses even more sports. The dynamics of the power unit rises to an even higher level, switching to increased transmissions is performed later, and on low - earlier. An optional sports exhaust system is included.
Sport Chrono package
Adrenaline One Pressing a button, excavating emotions: Sport Chrono - Sport Chrono Package with Motion Mode Switch and Porsche Track Precision application. Its functions provide even more sports settings of the chassis, engine and gearbox.
Motion modes switch with the Sport Response button on the steering wheel allows you to choose one of the five motion modes. This is Normal, Sport, Sport Plus and Individual, which gives you the opportunity to individually adapt the settings of the car to your driving style, as well as WET mode.
In Sport 911 mode, there is even higher dynamics. In the Sport Plus mode, the Porsche Active Suspension Management (PASM) system and optional Porsche Dynamic Chassis Control (PDCC) along with the rear wheel control system provide more sports depreciation and confident turning input.
In addition, the Sport Chrono package offers three more functions. The first function: Launch Control. In Sport Plus mode, it provides the highest possible acceleration when overclocking from the place.
The second function: the so-called "switching algorithm". At the same time, the PDK is designed for the shortest time and optimal points in switching for maximum acceleration. For uncompromising racing sensations and active transmissions.
The third function is Sport Response - turns on with the button in the middle of the motion modes switch. Engine and gearbox are focused on the maximum power return. As a result of the power unit, the maximum extent uses its capabilities for about 20 seconds.
The stopwatch on the front panel is part of the Sport Chrono package, which also includes dynamic engine supports: This electronically control system minimizes tangible vibrations and transmission oscillations and, in particular, the engine. Thus, it combines the benefits of tough and soft supports. In a word, improves stability and increases comfort. In addition, the Sport Chrono package includes the Porsche Track Precision application * to measure the time of circles and motion data. With the help of a smartphone, they can be recorded, analyze, compare and exchange them with other drivers.
PSM Sport
In combination with the Optional Sport Chrono Pack, the PSM system is complemented by a sports mode. This mode allows driving in a much more sport style, and the PSM does not turn off and monitors the situation in the background. This allows you to get more direct sensations from car management.
Sports suspension PASM.
The PASM sports suspension is also visited for the first time for models 911 Carrera S Cabriolet. Compared with the usual PASM suspension, the body is lowered by 10 mm. Springs are tougher and shorter, and transverse stabilizers on the front and rear axles have a greater rigidity on the twist. The rigidity settings of the springs were significantly increased, which makes 911 even more neutral and balanced on the road and the ring track, without limiting its existing fitness to the conditions of everyday use.
The front edge in combination with the sports suspension PASM has a more sporting form, the rear spoiler is extended even further. All this contributes not only to reduce the lifting force on the front axle, but also the creation of pressure forces on the back. Improving aerodynamics leads to a further increase in the challenges at surprisingly high comfort.

Air conditioning system
Dual-zone climate control offers the possibility of separate adjustment of the temperature for the driver and the front passenger. Filter of fine cleaning from activated carbon delays particles of dirt, pollen and odors, carefully removing even the smallest dust from the outer air before it falls into the salon. The automatic system is constantly monitored by air quality, reduces its humidity and, if necessary, stops the receipt of outer air, switching to recirculation mode.
Ionization
Optional ionization system improves air quality. To do this, air from the climatt control is pre-passed through the ionizer. As a result, the amount of viruses, bacteria and disputes are significantly reduced in the air, the air itself becomes noticeably fresh, and the microclimate in the cabin is more pleasant.
Hatch with lifting-sliding lid
The electrically conductive lifting and sliding cover of the hatch when opening is extended outward. Important advantage: The stock of space above the head is not reduced. Another advantage: a special design allows you to create a particularly large opening. For even greater pleasure from the open-air trip. The mesh wind reflector provides protection against drafts and contributes to greater acoustic comfort.
Luke with electric drive glass lifting and sliding lid
The electric drive lifting cap of the tinted single-layer safe glass is equipped with a power curtain with an electric drive, which protects against too bright light. The design of the cover, the stock of the space above the head and the area of \u200b\u200bthe hatch is the same as the conventional lid.

The headlights of all models 911 are fully fulfilled along the most modern LED technology. They differ rapid triggered and especially bright light. Typically for Porsche: 4-point day and near light. The luminous band between the three-dimensional rear lanterns is a common feature of all models 911. Here also uses the most modern LED technique. Also draws attention: the third stop signal located in the center.
LED headlights with Porsche Dynamic Light System Plus (PDLS Plus)
The LED headlights with Porsche Dynamic Light System Plus (PDLS Plus) are equipped with a dynamic corrector, a dynamic turning light, a nearest light control system depending on the speed and a dial-air assistant. For better lighting of the neighbor and far areas in front of the car, as well as the side zone - and thereby for greater safety.
LED matrix headlights with Porsche Dynamic Light System Plus (PDLS Plus)
An even better visibility guarantees LED headlights with matrix technology and a distant light assistant. The matrix technology provides for the possibility of targeted deactivation of the segments of the constant cone of light. 84 Individual Control LEDs adapt the level of illumination to the current situation using the light-adjustment or complete shutdown. Thus, it is prevented by blinding drivers of vehicles moving in front of you or towards you, but it provides excellent lighting the rest of the regions. To optimize the direction of the driver's side view, not only the elected weakening of the lighting of the oncoming transport is made, but also enhancing the brightness of the light to the right of the darkened area. If the light enters road signs with a strong degree of reflection, then a segmented lighting is produced, which prevents the driver's blinding. In addition, LED matrix headlights with Porsche Dynamic Light System Plus (PDLS Plus) possess an electronic system of rotary light, which optimally illuminates the turn by turning on and off separate LEDs.
Rare luxury in the modern world: time that allows us to focus only on what is right in front of us. On the road, for example. Or on the next turn. This will be supported by the help system that will allow you to keep full calm at the wheel.
Porsche Wet * mode
911 is equipped with an innovative system with a special WET mode, which recognizes the wet road and provides the driver to support the driver in such conditions. Thanks to the sensors in the front wheeled arches, the system can recognize the flying water splashes and thus determine that the wet road.
