What does it mean a car on the car. What is the difference between the drive drives and which drive is better to choose for your car. Types of drives used on cars

A lot of car owners still do not understand that they denote the encrypted types of drives, which is not surprising, because it is english abbreviations. Therefore, immediately clarify the situation: RWD - REAR WHEEL Drive - rear-wheel drive; FWD - FRONT WHEEL DRIVE - front-wheel drive; 4WD - 4 Wheel Drive - Drive for 4 wheels ("4x4"); AWD - ALL (Some Automatic sources) Wheel Drive - automatic drive to all wheels. Thus, the penultimate and last position are characterized by a complete drive, but with their individual characteristics.

Experience shows: do not be guided by such criteria as, for example, fuel consumption or car weight, when it comes to the level of safety. Although even the most "cool" jeep, acquiring the technique, is not insured against the loss of control, and decide why it is you needed and smell your abilities with the style of future driving.

If, studied specificationsYou continue to doubt, do not hesitate to apply for advice to specialists and just in case you ask them in detail about AWD drive: What is this transmission option?

Types of car drives

Let's get closer with each type of drive, as well as we will analyze the dignity and disadvantages.

RWD.

The use of such a drive creates the following advantages:

1. Light turn due to the small size of the radius. It is achieved due to the fact that the front wheels are not limited to the complex system of the leading bridge.
2. Even in the case of the rear independent suspension, the car does not need to install hinges of equal angular velocities.
3. Managed skid, which can be operatively localized by turning the steering wheel in its direction and adjusting the revolutions.
4. Lightweight steering Due to the lack of reactive moments.
5. Good overclocking dynamics and confident overcoming lifting.
6. It is valued by the strains, fansham lovers.
7. Optimal weight balance.

When moving mass vehicle RWD is transferred to the rear wheels, as a result of which the car gets the best grip with an expensive, and the dynamics of overclocking improves

Alas, together with advantages and disadvantages are revealed. Their less, but they are incommensurable significantly:

1. Insufficient handling on a problem road. This is especially felt at ice and raw soil. To optimize the control, the installation of more progressive stabilization and clutch control systems will be required. Partially improve this problem can costly profile rubber.
2. Apparatus with RWD, as a rule, are at times more expensive than their front-wheel drives. This paradox is due to a complicated transmission device and costly details of the chassis. This key circumstance must be taken into account during the purchase of purchase.
3. A leaning towards. Front wheels when turning causes increased resistance with which the rear drive does not cope; As a result, it turns out a slip, provoking driving.
4. Fuel faucet. A rare representative of the RWD family can boast that "eats" less than 10 liters per 100 km of mileage even on the highway.
5. The drive diagram is quite cumbersome and generates certain losses of thrust and power.

Typical representatives: BMW 3-Series E30, Cadillac CTS, Chevrolet SS and Camaro, Dodge Challenger, Charger and Magnum, Chrysler 300, Ford Mustang. and Sierra, Hyundai Genesis, Jaguar S-Type, Lexus GS, Mazda MX-5, Mercedes E-Class W124, Nissan 370z, Opel Omega, Scion FR-S, Smart Fortwo, Subaru BRZ, VAZ-2106.

FWD.

The front drive is initially characteristic of the resistance to turning: on turning the wheels due to its own traction, they seek to return to its original position. Such a property is considered a sign of a car safety and a favorable condition for a mid-level driver.

The car with FWD weighs 3-5% less than the vehicle with rear-wheel drive construction

The machine with this type of drive is most common in the global aircraft. For some time, she took a niche of the most economical and relatively inexpensive passenger vehicles. Calculated: its cost, weight and appetite is much less than the rear-wheel drive. On the conveyor is easier to collect the "Motor + front drive" node and elementary insert it under the hood, while for rear bridge We need a technological tunnel in the automotive painting and much more. Therefore, on medium-sized "cars" (especially mini-jeeps and parquets) put only front-wheel drive. This option is ideal for those who prefer to wheel settlements, sometimes leaving their limits. However, and outside the city is usually riding through a smooth road surface with minor damage. With such an uncomplicated mission, front-wheel drive apparatuses cope without much difficulty.

1. Compactness.
2. Relatively high passability.
3. Best steering efficiency.

1. Insufficient maneuverability.
2. Frequent slip of the front wheels with a sharp touch running.
3. Hard consolidation of the engine, as a result - tangible vibration.
4. Power limit ( force aggregate more than 200 liters. from. Introduces the chassis and worsens handling).

It is important! The interpretation "F" in the reduction of FWD as Full ("Full") or Four ("Four") is erroneous, absolutely incorrect and makes confusion to the classification.

4WD.

Constant four-wheel drive It assumes the stationary connection of all wheels through a multistage transmission system with a motor. For this, and serves as an inter-semicircle differential. So, the VAZ-2121 is equipped with its forced blocking, which puts "Niva" in one row with machines increased passibility with plug-in drive.

With the "4x4" format, you can adjust the rotation distribution between the wheels - some models have the ability to turn off the torque to the front axle (UAZ, Mitsubishi Pajero.). However, it is necessary to take into account that recently the four-wheel drive with the function of inclusion-shutdown plants manufacturers are extremely rare, because this option has proven itself as inefficient and expensive.

In many cars with 4WD drive provided independent choice Power distribution between four wheels

I must say that the transfer box gradually becomes rare. The mechanics displaces cybernetics, the autonomously monitoring process of rotation of the skates and supporting the optimal mode of operation of the transmission. Be that as it may, traditional schemes, when the driver can optionally include reduced transmission of thrust at low speed and increased turns crankshaft, still encounter. This is a very good help in a critical situation, for example, if the vehicle is stuck in the snow or on the smelting.

It is convenient when, if necessary, it is possible to turn on 2H - transmission to one axis acting as a classic rear drive. If this is not enough, switched to 4H and smoothly overcome the obstacles. However, the main chip, distinguishing 4WD from other drives, is a special technological mode - 4L (reduced transmission). With it, 4 wheels are completely blocked and rotated with the same frequency. For the city of said regime for nothing, but for a deep snowdrift or quagmines - just right! Clean engine power supplied by equal parts on both bridges will pull out of a viscous and loose mass without slipping.

Representatives: Audi Q3-SQ7, Bentley Bentayga, BMW X1- X6, Chery Tiggo., Daewoo Winstorm, Dodge Journey, Fiat Fullback, Jaguar F-Pace, Jeep Wrangler., Toyota Land Cruiser, Land Rover.

AWD.

This know-how has been applied mainly in crossovers. Its principle is that the leading shaft rotates the front axle and only in the case when the thrust is not enough, the electronics gives the command to start the rear axle. The distribution of thrust approximately corresponds to 60% on and 40% on the ass. But there are exceptions: at Audi and Subaru, the effort is divided into half.

AWD compared with 4WD gives a smaller torque. In addition, AWD has no possibility of incorporating a reduced transmission of torque (there is no demultipator-divider).

Automatically connected four-wheel drive most often used in modern crossovers

However, if we are talking about AWD and 4WD, we understand that nominally mechanical rotational energy there and it is distributed over all 4-rits. In fairness it is worth noting: in some corners of the planet, these two designations are generally identical. There they are neglected by the fact that the AWD is equipped with a special operating unit located in the middle of the car. It distributes the power on both bridges at its discretion, i.e., as it will consider necessary. Such a functional selectivity optimizes the acceleration process, strives for an economical ride manner, but when driving on ice or dirt, involuntary demolitions can be observed. In general, the work of AWD should be adopted, you need to learn how to feel it and predict the phases of activity, but it takes time and patience.

It cannot be said that the AWD transmission is safer when moving in winter. In this regard, experts warn: four-wheel drive by and large does not have the advantages in braking or on snowy, ice rotations. It only helps in certain points to maintain stability and creates an illusion of safety.

Suppose you are calmly driving around wet, slipping coating. Obviously, in such road conditions, the front-wheel drive is turned on in the car. But the car enters the problem turn. In this moment, the transmission responds to a change in the situation, and the car goes into unintentional skid. In turn, the driver in this situation also need to have time to react to this sudden "surprise", otherwise the accident cannot be avoided.

Difference 4WD from AWD

Speaking generalized, AWD provides automatically connected four-wheel drive, and in 4WD it is either permanent, or connected and turned off manually. By the way, in autothematics, there is still no well-established terminology sometimes violated, which confuses the consumer even more. Let's say, Ford Tempo and Subaru Justy "spinned" in the market as a car, equipped with AWD, although in essence adjustment of the operation of the leading bridges was performed in manual mode. But there is also such a thing in global practice as on "Demand Four Wheel Drive", that is, a 4-wheel drive connected in case of need. It is unclear who the system is managed by this system - a person or robotics. One way or another, is guilty of such a "winery" mainly irresponsible media allowing Lyapsus when publishing auto-outings, price-sheets and press releases, as well as Internet copywriters who are unwittingly distorting information in pursuit of uniqueness.

PART-TIME 4WD appeared first and is the easiest and most reliable type of full drive

Formerly, cars were in the overwhelming majority of monophers, with the rear (less often - anterior) leading pair. Then there were samples with a dispensing box ("Distribution"). Through it, the traction was distributed between the axes in the proportion installed designers. So the first all-terrain vessels appeared. Later, a number of versions of the all-wheel drive version of the transmission were invented:

• PART-TIME 4WD - partial four-wheel drive. Only a short-term use of a system of this type is allowed, for on dry solid roads, its increased wear and failure is observed.
• Full-Time 4WD is a total unleated drive. The torque is continuously distributed between the bridges in the ratio, which has a constant value. Auto in such a drive mode moves along an arbitrary area, however, to achieve truly off-road qualities, it is supplied with a rigid blocking of inter-axis and intercoles differentials.
• AWD is a four-wheel drive working in the mode of the machine. The computer or the viscose coupling determines the moment of slipping the wheels on its own, additionally connecting the second bridge.

What is better in different situations

AWD or 4WD, FWD or RWD? Due to the fact that many are lost, the car with which transmission system is to buy, the controversy does not subscribe among motorists, which type of actuator today is the most relevant. Analysts on this occasion also broke a lot of copies ... Let's deal with this problem.

In the first place, when choosing a product is factor correlation cost with the financial potential of the buyer. The second is its taste preferences. On the third - features of the place of residence and lifestyle.

If we are talking about frequent movement of off-road, it is recommended to choose cars with a 4WD drive, in the city quite enough FWD

For Southan 4WD and AWD, in principle are not relevant, especially if you consider that they are more expensive, and fuel consume more. They are enough to purchase an advanced-wheel drive, or even a rear-wheel drive apparatus with high-quality winter tires. In any case, it will be rationally, motto.

In the middle lane with moderate winter it is best to suit FWD. Its advantage in the cold season is that on front bridge The largest mass of the car is concentrated (gearbox, motor, suspension). Thanks to this, the leading front skates have an optimal clutch with an expensive, unlike the rear drive.

For mountain, sandy terrain, swamps, snowdrifts uniquely requires 4WD. AWD is also designed to overcome off-road, but more passable. On the big steepness and on the impassive dirt, it is not suitable - does not pull. In addition, cars equipped with AWD, have a slightly smaller road clearance, rather than full all-wheel drive, which are 4WD. Therefore, on AWD it is not worth tempting fate and drive through the rocky trails or forest bodies and docks.

AWD is an advanced, smart system of the XXI century. In the measure of capricious, for it is in the stage of improvement. However, for the urban cycle, as well as for soft winter Scandinavian type is an error-free solution. In addition, AWD compared with 4WD consumes a significantly smaller volume of fuel.

As for RWD, the current experts note its impracticality and inconvenience in almost all aspects.

The rear-wheel drive was provided on the so-called "classic" VAZ cars

Mostly the population becomes the owner of the TC to ride it to work and home. The most balanced option for this purpose is the front-wheel drive small car. The fact is that the front-wheel drive will noticeably saves fuel in comparison with a more weight-drive version.

Currently, there is a tendency of gradual refusal from RWD, which is not surprising, because this is the Trend of the last century. To date, he mainly remained on the crashes and powerful sedans. And in the latter case, it is a tribute to tradition and new fashion, and not a need, since it is possible for a full-fledged drift with rear-wheel drive. The super-SUV rear-wheel drive (in particular, 4 Runner and Tahoe) is also rather an exception to the rules for the maximum expansion of the capabilities of the model. Other rear-wheel drive cars (for example, pickups) are created in order to transport goods. And the bulk of all-terrain vehicles is equipped with a "4x4" drive for maximum power and torque. AWD in a certain sense acts here in the role of universal development.

When choosing a car came across the driver's question. Tell us about the types of drives of existing in the car. Thank you.
(Igor Kondratyev)

It is known that the engine compresses and burns fuel, converting it into mechanical energy. This energy forms a torque and transmits it to the wheels. The drive is called the axis of the wheels on which rotational movements are transmitted. It can be the front, rear and complete.

Each of the types of transmissions has its own characteristics, as well as advantages and disadvantages.

[Hide]

Front

On the front-wheel drive vehicles, the engine, generating energy, transmits it to the front axle or simply put - on the front wheels. This design extends most often on the machines budget class, however, meets on more expensive cars. Related by the fact that such a layout is satisfied simple and practical.

Learn how to control the front-wheel drive car is much easier. Because such cars are preferred for beginners. Of the disadvantages: has lower dynamic indicators and an increased probability of demolition of the front wheels. The advantage is the high passability on slippery roads and a smaller degree of drifts, unlike the rear-wheel drive cars.

Rear

Obviously, in such a design, the rotation energy is transmitted to the back pair. It is found on expensive cars, especially European and American production. In terms of speakers and high-speed indicators Such cars take their advantage. Due to which it has good maneuverability and handling. That's just a tendency to drift by car with front-wheel drive above. This is due to the fact that the front wheels at the moment of rotation are a braking factor, and the rear - excessive pushing force.

Full

The car whose torque is distributed to all axles is all-wheel drive. Perhaps the most common of all existing types. Such a layout have a car of almost all classes and types of body. In addition to high passability and versatility, this design has deserved its popularity of the so-called system "plug-in" drives.

Such a solution allows the machine to use the leading one axis of wheels and, depending on the situation and road conditions, connect the second.

It turns out that the full type has three groups of transmissions:

• full, using the front and rear axles at the same time;
• connected full on request, where the lead is the front axle of wheels, and the rear connected;
• automatically plug-in - the master is usually the rear pair, and the front turns on automatically, as soon as the driving wheels lose the clutch with the road.

All modern cars, regardless of the type of drive, are most often supplied by the system. stabilization ESP.. Thanks to this system, your car will behave on the road as comfortable and calmly as possible.

Types of drive.

Almost every car enthusiast knows how the actuator has a car, well, or at least knows which drive on his car. Let's figure it out, what other types of actuators exist and what are their differences. So, in order for the car to go, it is necessary that the torque from the motor of the car is transmitted to its wheels. Depending on how many wheels this torque will receive, depends on the type of drive.

There are three types of drive: front, rear and complete.

Front car drive.

The front-wheel drive cars receive all the engine energy to the front wheels. At a minimum, it is logical, because on most cars the engine is in front and the front part is more loaded, and therefore it has a greater grip of the front wheels with the road. More often such a drive is found on modern budget class cars, but it happens on expensive models. The front-wheel drive car is pronounced in turns on an inhomogeneous coating, but much less to a lesser extent than cars with rear-wheel drive. But still cars with front-wheel drive are much more likely endowed with a different disadvantage - insufficient turning, that is, the demolition of the front leading wheels to the outer radius during the passage of turns. And if this "ailment" in most regular situations does not make anything about himself, then with active driving, it can cause a lot of trouble to the driver. If there is insufficient rotation, the dynamic stabilization system considered by us can enter and liquidate a potentially dangerous situation. In addition, with an active start, the front of the car is unloaded, as a result of which no longer has the maximum clutch level with the road. For this reason, the front-wheel drive vehicles are difficult to realize the entire potential of the engine during acceleration, if its power exceeds the value of 200 hp For the best behavior of the car on the road, it is equipped with Anti-test system Or blocking an interstole differential to avoid slipping the leading wheels.

Benefits Front drive:

disadvantages front type drive:

• Vibration from the motor due to the rigid fastening is transmitted to the body.
• The steering wheel with intensive acceleration transmits reactive efforts (expressed by the form of impetus). Therefore, front-wheel drive cars with a capacity of more than 250 hp As a rule, they are not issued due to the inability to realize the potential of the engine.
• With a sharp start, there is a redistribution of weight back, the front axle is unloaded, and leading wheels have a tendency to slip.
• Demolition of the front of the car.

Rear car drive.

With rear drive, the engine energy is entirely enrolled on rear wheels. Positive side This drive is excellent handling and dynamics, the lack of vibration (transmitted to the body and steering wheel) has a positive effect on comfort for both the driver and passengers. Therefore, on modern cars, rear-wheel drive is used on premium brand models or in sports models, in which gambling handling and "pure steering wheel" are important, which will not be transmitted vibrations, worsening the "car sense". One of the main minuses of the rear drive is a tendency to drift, especially on a slippery road. This effect manifests itself in the fact that with an excess of thrust on the drive wheels, the back of the car begins to enter - it is called a drift or excessive turning.

Advantages of the rear drive:

The steering wheel does not affect the reactive moments during acceleration, which improves the quality of control over the car.

With a quick and sharp acceleration from the place of weight, the car is redistributed back and leading wheels are less prone to slip and loss of adhesion with the road, which makes it possible to more effectively.

The load on the axes is well distributed, the work is optimally distributed between the front and rear tires, which prevents their rapid wear.

Disadvantages of the rear drive:

Horregious in production, which is reflected in the final price of the car.

Cars with rear wheel type harder in comparison with front-wheel drive. They, as a rule, always in the center of the body there is a tunnel, "eating" useful volume of the cabin and reducing the comfort of the rear passengers.

Patency in snow and dirt is worse than the front or all-wheel drive machines.

Template to drift rear axis car.

Four car drive.

When the engine energy is transmitted to all four wheels of the car, such a drive is called full. In the bad weather or complex road conditions, motorists often arise about the acquisition of a car with a drive for all wheels or, in other words, all-wheel drive car. At the mention of this type of cars, SUVs come to mind the midst, but in modern conditions it is most likely the established stereotype: all-wheel drive transmission today - not the prerogative of "jeeps", but a completely traditional common scheme, albeit with many variations in execution, But occurring even on small ages. To the pros all-wheel drive cars It applies good permeability and the ability to start from the place without slipping the wheels almost on any road covering. The main minus of the full drive is heavier and expensive. In some moments, the behavior of a machine with a full drive on the road can be unpredictable. It may occur, due to the uneven distribution of torque on the wheels (for example, one wheel loses the grip with the main coating of the road). This type of drive requires careful driving.

No matter what drive the future owner chooses modern carIt will be supplied with a system of dynamic stabilization that will make your trip as comfortable and safe for unpredictable road conditions. Before reading the various options for the full drive, it is necessary to define such a device as the differential and the reasons for its need for a scheme design of any type of drive for cars.

The differential is a gear device transmitting torque to drive wheels and providing them with different rotation speed to ensure the turn of a / m without wear of the tires (in the inner wheel path shorter than that of external).Differential is one of the main design elements of the transmission.

The location of the differential in the transport transmission:

In the rear-wheel drive car to drive the drive wheels - in the rear axle crankcase;

In front-wheel drive car for drive drive - in the gearbox;

In the all-wheel drive car for drive wheels - in the front and rear axle crankcase;

In the all-wheel drive car for drive leading bridges - in the transfer box.

Differentials used to drive leading wheels are called interstoles. The inter-axis differential is established between the leading bridges of the all-wheel drive vehicle.

The presence of differentials is the main stumbling block in the full drive technology, since it has a huge impact on the behavior of the car on the road. If you consider the simplest example of AWD with three "free" differentials, it becomes clear that the car can be immobilized with the clutch loss of at least one of the four wheels. A feature of a simple "free" differential is that it redistributes power in favor of an axis having less resistance.

Thus, if one wheel loses the clutch with an expensive, all developed power is transmitted to it. At the same time, the all-wheel drive car has twice the chances of losing the clutch of one drive wheel with an expensive than a car with a drive per axle. And since the use of a all-wheel drive vehicle involves a more frequent ride in bad road conditions for it becomes very important to have any blocking of differentials: inter-axis, interstole or everyone together.

Automakers introduced a sufficiently large number of layout diagrams and formulas, so let's try to clarify some points. In turn, the four-wheel drive can be divided into subtypes.

Connected full drive(PART-TIME)

PART-TIME 4WD, (English "Part Time" is part of the time) - a complete drive of temporary use. When driving on the roads with a firm coating, all the thrust is transmitted only to one bridge, as a rule of rear. The second bridge is connected by the driver using the lever or buttons.

In vehicles with a plug-in full-wheel drive, there is no inter-axis differential, which would allow cardan shafts to rotate with different speeds when the car turns. With the full drive of the front and rear cardan shafts through disposal box It is toughly connected to each other and rotate at one speed. In the turn of the front wheels of the car pass a bigger way than the rear, which appears stresses in transmission, increased rubber wear and so on. We can weaken these effects only by slipping the wheels. Therefore, the use of such a complete drive is limited to sections with a very low clutch coefficient (dirt, snow, ice, sand). On the road with a dry solid coating, connect the four-wheel drive of this type is not recommended, in order to avoid serious breakdowns.

Automatic connected full drive (Tod - Torque on Demand - torque on demand).

In such a system of full drive in normal road conditions, only one bridge is leading. The four-wheel drive is connected if necessary. As a rule, this happens when the wheels are slipped and, as soon as the slip is eliminated, the four-wheel drive turns off. To connect the second bridge, an ussociation can be used, or a multi-disc clutch driven by hydraulic pump, self-locking when the difference in the speed of rotation of the front and rear axle appears; or a multi-disc clutch with electronically controlthat receives information about slipping from ABS sensors and capturing the slightest difference in speed of rotation of the front and rear axles.

If the motor task is to create a torque, then the transmission is assigned a role in its transmission to the drive wheels. Depending on which of them - front or rear - are connected using a transmission with an engine, the car is considered an editorial or rear-wheel drive. In this article, you will learn what the rear-wheel drive is different from the front and what the advantages and disadvantages of both of these schemes.

The first cars were produced on the rear-wheel drive scheme. This is explained by the simpler engine location, gearbox, rear axle gearbox along the longitudinal line of the car case. The flexibility of the connection provides a cardan shaft.

The rear axle, in the casing of which there are two semi-axles with wheels, is located at a right angle to the Cardan axis. For such a layout I had to create a full-size gearbox. The complexity of its device lies in independence of two rear wheels: When turning, the internal moves faster than the external one.

The operation of the gearbox to see is quite simple: it is enough to lift the jack one of the rear wheels, start the engine and turn on the transmission (laying under the front wheels of the shoe). The wheel standing on the asphalt will be motionless, and hanging in the air will begin to spin. This is the operation of the differential distribution torque between the rear axle semi-axles.

Front drive: device and reasons for popularity

The principle of transmitting the rotation of the motor, the gearbox shaft on the wheels is similar to the rear-wheel drive: a gearbox with differential and cardan shafts is necessary. The difference is in the constructive solution of these nodes and aggregates.

The front wheels, being leading, demanded a closer placement of the PPC to themselves. This made it possible to place a bunch of engine-gearbox on one axial line with wheels in the front engine compartment. Cross placement of the motor Forced engineers to create a more compact engine and the speeds of the speeds while maintaining their capacities. Therefore, despite the emergence of an experienced first sample of the front-wheel drive car at the beginning of the 20th century, they have become massively produced only in the second half of the past century.

If the gearbox, the gearbox in such a layout is similar to the rear-wheel drive, then the cardan has a significant difference. IN front-wheel drive scheme Shruses are involved, or ball gearbox gearboxes. If Cardana Cross has two degrees of freedom, then the shruses connect two semi-axes more smoothly. The angle of this articulation reaches 70 ° without serious, unlike cardan, wear of rubber parts. Also, shoes allow you to change the angle of rotation of the wheels - control the car.

Comparison of two types of drive: their advantages and disadvantages

Despite the differences in the details of the layout, the front-wheel drive is designed with the placement of the motor in the area of \u200b\u200bthe front wheels. The rear-wheel drive scheme is more flexible in this regard and allows the motor to be anywhere. There is an adjustable, medium-engine (in front of the driving wheels) and the rear-engine layout. To understand what the rear-wheel drive differs from the front in practice, it is necessary to compare their strengths and weaknesses.

Pluses of rear leading wheels

• Rear-wheel drive allows you to achieve high machine maneuverability due to lower limit on the angles of rotation of the front wheels.
• Good sustainability on the ground: the leading steam works along the front pair of Kae.
• The elongated bunch (motor, driven front wheels and the leading rear) allows you to more gently control the machine when driving - uncontrollable demolition from the led beam cloth.
• When starting from the place, the mass of the body is transferred back, increasing the clutch of the tires with the road.

disadvantages

• Rear-wheel drive is more inclined to drift.
• Such a scheme requires a larger working volume, not allowing minimizing body.

Problems of front drive

• Concentrated Mass in Front motor compartment (Engine, gearbox, gearbox, semi-axes, shoes) eliminates proportional toolting on the body.
• Overclocking from the place often occurs with the slip due to the weight transfer of the body back.
• When driving the car on the road is more difficult to keep due to combining in the front wheels of the managerial and drive function.

Dignity

• Such a layout makes the car more passable on the wet soil: she drags the car, like in a tug, and does not push the entire weight in front of them, as with rear drive.
• The front-wheel drive gives the machine less weight, the compactness of the placement of the aggregates, which makes it easy to modify the body in two and even the single-visuous layout option.
• The inhabitual combination of the control of the machine both in speed and in the direction allows you to better "feel" the steering wheel.

Modern technologies compensate for many of the difficulties of the front and rear drivesTherefore, the choice often depends on the personal taste of the user, and not the capabilities of the car.
