Grant increased fuel consumption. Fuel consumption frets grants with automatic transmission. Air conditioner and other electronics included

In reality, the fuel consumption is determined for a mixed driving cycle.

At the same time, according to the reviews of the car owners of the model in question, the actual combustion of gasoline occurs differently. So:

• in urban conditions, the standard 100 km goes from 7.1 to 19.7 liters (the average value, respectively, is 11.8);
• on the highway - 6-10.2 (7.6);
• combined cycle consumption - 7.2-14.8 (10.4).

As it is easy to see, the difference is, for the most part, very significant. Why is this happening? Let's talk about this below.

How to find out the expense yourself

The method described here allows you to determine as accurately as possible for your specific case the amount of fuel burned per 100 kilometers.

The procedure is as follows:

• having exhausted the fuel as completely as possible, the tank is poured to capacity, that is, until the pump pistol makes the first "shooting";
• the daily mileage scale is set to zero;
• after one day, compare the distance covered by the car with the fuel consumption.

For example, if you drove the conditional 400 kilometers and consumed 31 liters of fuel, then dividing the sum of liters by the first number and multiplying the result by 100, we get 7.75, which is the real value for you.

By acting in this way, you will know exactly what the exploitation of Grants will result in.

Basically power point Grants belongs to the subcompact category. These vehicles are generally not capable of consuming a lot of fuel. However, there are many factors that directly affect this indicator. We will talk about them in more detail below.

Equipment

This is one of the most significant factors affecting the total fuel consumption of a vehicle. In particular, we mean the differences in:

• types of bodies;
• types of power units;
• electronic equipment;
• mechanical or automatic gearboxes, etc.

For example, the sedan and liftback are produced in three versions each. The difference lies in the power of the unit and, accordingly, their gluttony also differs. So:

• a 98-liter engine will burn 7.8 liters at a rate;
• by 87 - 7.2;
• by 106 - 6.9.

It is worth knowing that the weakest of them has 8 valves, while the rest already have 16.

The only exception the designers made for the Sports Grants. On this model they put power unit by 1.6 liters (this parameter is the same for all cars), but its power is higher - 118 l / s. Moreover, the sports version is also equipped with a 5-position gearbox.

Curiously, with all this, having a 16-valve engine, the aforementioned model, according to the manufacturer's standard, spends only 6.8 liters per hundred kilometers. This is a very modest figure in comparison with other relatives.

Fuel quality

Reviews of the owners of the Grants indicate that the amount of consumption differs significantly from what kind of fuel is used to refuel it.

The manufacturer, for its part, recommends giving preference to a better brand, that is, AI-95. Moreover, practice confirms that the aforementioned grade of gasoline is burned more economically than the cheap 92nd. At the same time, the difference is so significant that it is more profitable to use expensive fuel.

This circumstance should also be taken into account in order to optimize the operating costs of the vehicle in question.

Highways load

Driving around the city is usually seriously hampered by the abundance of cars on the streets. This constantly leads to traffic jams. As a result, the operation of the engine requires more gasoline.

The situation is aggravated in winter and summer, when it is also necessary to either heat the interior of the car or cool it.

In total, consumption can grow several times under the influence of all the factors mentioned above.

Driving style

Fuel consumption also largely depends on it. Lovers of speed and spectacular starts with abrupt stops spend more fuel than calm car owners.

Moreover, when the driver constantly starts with a cold engine, the amount of gasoline burned usually increases by about 12 percent.

As noted earlier, the employment of different electronic systems, and including an air conditioner, fuel is also required. The more gadgets and “gadgets” are installed on the car, the more difficult it is to save gasoline.

Only one conditioner can "eat" an additional 15 percent of the total.

Seasonality

The most expensive car is in winter and summer. Moreover, it is more difficult to have it in the cold season, because in the heat, the owner only needs to monitor the temperature of the engine and the operation of the air conditioner. In cold weather, consumption is also influenced by other factors:

• winter tires;
• heating;
• heating systems for mirrors and rear-view glass;
• the need to drive as carefully as possible, etc.

There are certain techniques for determining the average fuel consumption of a car engine. By the way, they are approved by law. The car is not tested at landfills, but driven to special laboratories with "ideal" conditions. Next, the wheels of the machine are installed on the drum, which simulate urban and suburban operating conditions. That is why in most cases real expense does not match the factory one.

Add to this the factor that the driving style is different for most drivers.

Factors affecting fuel consumption

Fuel consumption of 8 valve engines

Engine (model)	Engine power (hp)	Engine volume (cc)	Fuel consumption in urban cycle (l / 100 km)	Fuel consumption In the countryside (l / 100 km)	Fuel consumption in a mixed cycle (l / 100 km)
11183	82	1596	9.7	6.1	7,4
11186	87	1596	9	5.8	7,0
21116	87	1596	9	5.8	7,0

Fuel consumption of 16 valve engines

The data is presented for Lada Grant cars equipped with manual transmissions.

As you can see from the tables, the consumption of 16 valve motors just below the 8 valve. And there is a version with powerful engine expensive. Therefore, we want to ask your opinion.

Test lamp technique

The simplest of them, and as it seems to me the most biased, is carried out by the fuel control lamp. Its essence is as follows:

1. as soon as you light up control lamp"Gas stations", you need to fill up 20 liters of fuel.
2. Reset daily mileage.
3. Wait until the control lamp of the "gas station" lights up again and divide the distance traveled by 2. For example, if you have driven 300 km, then you need to divide 300 by 2 (300/2 = 150 km). This means that on 10 liters you drive 150 km. Or divide 20 by 300 and multiply by 100, it turns out that in this case Your fuel consumption was 6.6 liters per hundred kilometers.

At 20 liters, the car drove 412 km

This method cannot be called accurate, especially considering that the control lamp on the Lada Granta lights up when she wants to, from any slide, it can even light up from a sharp press on the brake pedal (emergency braking).

Tank to tank

This method is the most accurate if you follow all the rules. Its essence is as follows:

1. with a minimum fuel remaining in the tank, it is necessary to fill full tank, before the first "shooting" of the gas station pistol.
2. Reset daily mileage.
3. Wait until the fuel level drops to the minimum mark (the lower the level, the more accurate the measurement will be) and refuel until the tank is full again, before the first “shooting” of the gas station pistol.
4. Next, compare the readings of the daily mileage and. For example, if you drove 500 km, and spent 41 liters of fuel, then the fuel consumption of the car will be (41/500) * 100 = 8.2 (8.2 liters per 100 km.)

Average fuel consumption by on-board computer

The main world methods of measuring the consumption of new cars

As we wrote above, there are several methods for measuring the average fuel consumption of cars. Let's tell you more about them.

NEDC

On the territory of Europe, the most common cycle is the NEDC type, which was developed about forty years ago. This is what causes accusations from experts who say that the method is not modern.

Structure of the NEDC algorithm

The main feature is that manufacturers are allowed to use a selective method of choosing a car. We are talking about the fact that for testing, cars are provided with already run-in nodes, special lubricants low viscosity, as well as with the most compact tires that can be installed on a car.

In addition, if desired, testing can take place with the radio turned off, heating, and so on. This allows you to "select" those results that would best suit the manufacturer.

Measurements are carried out in urban (NEDC UDC) and suburban (NEDC EUDC) cycle. The length of the "urban test" is 780 seconds, while the suburban movement assumes a time period of 400 seconds. In the first case average speed will be a little over 18 kilometers, and in the second - about 62.6 kilometers per hour.

This technique is criticized because many models with an additional electric motor can travel most of this short distance without using an internal combustion engine. This is the source of amazing results with extremely low fuel consumption, even in sports cars.

FTP-75

But these standards no longer meet market requirements, so manufacturers often turn to the American FTP-75 standard. It is considered the closest to reality, although experts talk about problems with the lack of areas where movement occurs evenly.

Dependence of the speed of the FTP-75 algorithm

It is similar to the European NEDC, including an average speed of 34.1 kilometers per hour. An advantage is that the test duration is 1,874 seconds, which makes it harder for hybrid car models to show “unrealistically low” fuel consumption figures. But, most importantly, the American version of the test obliges manufacturers to turn on the air conditioner if it is included in the package.

As a result, fuel consumption in this test is 10 or even 20 percent higher than in the NEDC.

Japanese cycle JC08

In the case of the JC08, the difference will be even greater. The fact is that in it the number of accelerations and decelerations is maximum, and long sections with flat speed parameters no at all.

In addition, the maximum speed does not exceed 80 kilometers per hour. On one of the sections, the length of which is 8.2 kilometers, the average speed does not even reach 25 kilometers per hour.

The "slowest" known method for calculating the average flow

Of course, we can talk about the stiffness of the test, but it takes into account the increased traffic load, which is typical for the island country of Japan. In addition, drivers of most large cities around the world are in such conditions. So, it is worth considering this technique as the closest to reality.

In general, there is no optimal testing method yet. The options available represent a compromise that car manufacturers try to use it to their advantage. Therefore, you should always try to take into account the specific methodology that gave the results indicated in the vehicle specifications.

The main technical factors that affect fuel consumption

Basically, the fuel consumption of a car is affected by:

1. The quality of the fuel itself. If you are unlucky and instead of good fuel the car was filled with a "badyagi", then you have to.
2. the cleanliness of the filters (s). These breakdowns can be diagnosed by yourself. The most common reasons are not meeting the deadlines for replacing filters.
... This situation is very common. This is due to bad weirs, water gets into brakes and disrupts their work, knocks out the lubricant from there, as a result of which there is a "acidification" of the mechanisms.
3. ... This is of course a controversial issue. Due to the design features of the cooling system. Previously, this phenomenon was considered a breakdown, now, on the contrary, AvtoVAZ issued a reverse prescription and.

In 2011, the Volzhsky Automobile Plant launched mass production budget front wheel drive Lada car Granta. Developed on the basis, it changed in lineup family Samara, becoming the first car with serial installation on the automatic transmission conveyor. Having a subcompact engine, Lada Granta is very economical in fuel consumption.

How are consumption rates determined?

Fuel consumption, that is, the amount of gasoline consumed per 100 km of track, in many countries is recognized as one of the most important characteristics... Vehicle weight, engine efficiency, transmission ratios, power consumption of accessories, tire quality, performance fuel pump, braking and other factors affect the specific fuel consumption. Aggressive, overly active driving also suggests more.

In the recent past, the calculation of fuel consumption was determined by professional drivers during factory tests on specially equipped tracks. At the moment, the new principle of such approbations shows high reproducibility of results. But in a standardized test in a test lab, the vehicle is operational, refueled with reference fuel, and all auxiliary electrical equipment, air conditioning, and lighting are off. At the stand in automatic mode cycles of uniform motion and acceleration-deceleration are performed.

The manufacturers publish the data obtained on the test bench, which is not the norm. Aggressive driving style and second acceleration, engine and fuel metering system malfunctions, low tire pressure and car load, jammed brakes and transmission malfunction - these are not all reasons for incomplete fuel combustion and, as a result, a significant increase in gasoline consumption. If the car is technically sound, then in normal driving mode an experienced driver will be able to reduce fuel costs.

You should be aware that fuel consumption increases by winter time, on mountain roads, when transporting bulky cargo. Cars from the assembly line, with the air conditioner running, as well as engines after overhaul consume more fuel.

Factors Affecting Grants Fuel Consumption

IN technical parameters Lada Granta AvtoVAZ indicates the consumption of gasoline per 100 km of track in the amount of 6.8-7.8 liters (it all depends on the configuration of the car). However, when operating a car, drivers are often faced with the fact that the actual fuel consumption is almost twice as high as declared by the manufacturer. The main parameter that affects the actual fuel consumption is the driving cycle.

This is a virtual route along which the car passes in accordance with a strictly prescribed scheme of acceleration and deceleration, the minimum and maximum speeds in a certain mode, and for a mechanical box at each moment of the cycle, a gear is determined. That is, imitating traffic on a city road or highway, fuel consumption is determined. In reality, various factors affect the consumption of Lada Granta gasoline.

1. Depending on the season, during the frosty winter months, fuel is used to heat the passenger compartment. It takes longer to warm up the engine. Braking on icy conditions also does not contribute to fuel economy. However, in summer, when using an air conditioner, fuel consumption also increases by at least 1 liter.
2. The quality of gasoline, that is, what kind of gasoline is poured into the car. Based on the results of tests and observations of drivers, it is much more economical to use AI-95 on Lada Granta than AI-92.
3. Driving style. Fuel consumption increases several times with aggressive driving style with hard braking and acceleration.
4. The scourge of large cities is traffic jams. Due to uneven city traffic, Lada Granta drivers in cities always have higher gasoline costs.
5. Defective systems and components. Working in a harder mode, the car consumes more fuel.

Features of consumption depending on the gearbox

It consumes more fuel, since the driver controls the manual gearbox, and the automatic gearbox switches on its own, with a slight delay. For Lada Granta with manual gearbox, the gear engaged while driving is very important. By analyzing his daily journey, the driver can determine the real gas mileage of his car. According to the reviews of Lada Granta car owners, it turns out that 100 km are spent:

• in the city - automatic transmission 9-12 liters, manual transmission 7-11 liters;
• on the highway - automatic transmission 8-9.5 liters, manual transmission 6-7 liters.

In winter, the indicators are maximum, in summer they are minimum. Thus, a tank volume of 50 liters allows you to drive more than 500 km. In city mode, drivers are forced to combine aggressive and calm driving, hence the average consumption run-in gasoline Lada Granta 8 l / 100 km. Reducing fuel consumption by 1.5-2 liters will help the use of engine braking, right choice transfers (on mechanics) and driving only in the extreme right lane for by public transport... On a suburban highway with a smooth ride on a flat road surface values ​​of 5 liters are observed. However, with sharp braking and a quick start, with constant overtaking, the flow rate increases to 6-7 liters.

Fuel economy principles

Reducing the cost of gasoline Lada Granta is not difficult at all. First of all, you need to understand that the deeper and more often you press the accelerator pedal, the higher the gas mileage. And the less often you use the gas pedal, the more fuel you save. The main skill that trains over time is the ability to brake the engine. Any driver will easily get used to rarely using the brake pedal if desired.

When braking by the engine, the load on the braking system is noticeably reduced, fuel is saved. Grants, thereby, will last longer brake pads and all brake system... When the engine decelerates, the fuel consumption is zero. According to experienced drivers, the savings are at least 10 percent.

In colder months, the vehicle takes longer to warm up. However, the modern Lada Granta has the ability to warm up in motion, and there is no need to warm it up for too long. On a cold engine, do not just accelerate sharply. And if there is a goal to save on gasoline, you should avoid slipping and accelerate smoothly and evenly.

Significantly more gasoline is consumed on uneven or dirt roads... The extra pounds in the trunk of your car increase fuel consumption, so don't carry anything extra with you. Substandard car oils lead to various engine malfunctions and Lada systems Granta and increase vehicle fuel consumption. Spend technical inspection car in a timely manner. By following these simple tips, you can reduce your gasoline costs.

Domestic cars have always been famous for their modest appetite for fuel consumed, but many are still interested in the question of how much fuel Lada Granta consumes, especially against the background of the fact that, in addition to the Standard version, only gasoline of at least AI-95 must be used in engines due to the design features ... Today we will discuss this issue with you.

What is the fuel consumption for Lada Granta?

The manufacturer, represented by AvtoVAZ, regulates fuel consumption for Lada Granta in the combined cycle from 6.7 liters per 100 kilometers, up to 7.6. The most "voracious" version is expected to be the version with the "automatic", and the most modest appetite distinguished Grant with a new VAZ 21127 engine with a capacity of 106 hp. But the passport data are not always reliable, since they are achieved in the "greenhouse" conditions of the landfill. We are interested in real tests.

Since all VAZ engines are similar in their appetite, an example would be the VAZ 21116 engine, which is aggregated to the "Norm" version. It has a lightweight piston group, which has a positive effect on fuel consumption. Experienced vehicle passed at the moment 13-14 thousand kilometers in a city with a population of 800 thousand people and 2 thousand on the highway. For all this mileage, consumption at the time of this writing is 7.4 liters. Let me remind you that in the combined cycle for this engine, a consumption of 7 liters per 100 kilometers is regulated. Our mode is not entirely mixed, there are not so many tracks, so I think it is correct to say that in the head Oddskie indicators of consumption this motor has kept within. It should also be noted that when measuring fuel consumption, the car drove at ease, fuel economy stood atlast place. The owner, that is the author of this article, did not deny himself the pleasure of a ride "with a breeze" and did not jam the car in the cold.

Why does my Lada Granta consume a lot of fuel?

On specialized forums, you can find messages from people who complain that their Lada Granta uses an on-board computer in the city to consume 12, and sometimes 13 liters of fuel per 100 kilometers. Why then, one wonders, on one car the consumption is 7.4 liters, and on the other 12? The answer is very simple. For a more accurate measurement of fuel consumption, you need to drive at least a thousand kilometers and check the consumption, which is called "by receipts" or "from light bulb to light bulb." How to do it? We are waiting for the remaining fuel lamp to light up - this means that you have less than 7 liters of fuel in the tank. We fill a full tank or it is necessary e the amount of fuel, measure the mileage and wait until the remaining fuel lamp lights up again. Thus, we refuel and measure until we have traveled a thousand kilometers. Next, we calculate the consumption using a simple formula: (Fuel quantity / Mileage) * 100 = average consumption.

Example: we filled in 100 liters of fuel and traveled 1000 kilometers. Our average consumption will be as follows: (100/1000) * 100 = 10 liters per 100 kilometers.

Among other things, the urban driving style will fluctuate greatly depending on the congestion of the roads on which the car drives, on the duration of the trip, warm-up time, and the duration of parking with the engine running. Do not forget the expense for Idling strive for infinity. And even if, according to the results of the calculations, you received a result of over 10 liters of fuel per 100 kilometers of city driving, do not despair, this does not mean that the car systems are malfunctioning. To check the health of the systems, it is required to conduct a simple test: we reset the readings of the on-board computer, go to a free track and drive 5-10 kilometers at a constant speed of 80-90 km / h. If the test result is a consumption of 4.5-5.5 liters, then all the systems of your car are working properly, and the reason for your car's “big appetite” in the city lies in the driving style, traffic congestion and the duration of the trips themselves.

Also, do not forget that the plant regulates the fuel consumption indicators only when using fuel with an octane number of at least 95. When using any other fuel, the manufacturer is the fuel efficiency of its engines.

The following videos will be able to answer this question most fully, which will show the summer and winter fuel consumption of Lada Granta.

Reducing fuel consumption on the Lada Granta

For modern world characterized by constant, pleasant and not very, changes that affect the most diverse aspects of people's lives. The rise in prices in general, and in particular - the rise in fuel prices, cannot be attributed to positive changes.

Naturally, the change in gasoline prices towards their increase makes the absolute majority of car owners seriously think about saving. Refusal to use a car is an extreme measure, which very few car enthusiasts decide on, but attempts to reduce fuel consumption are not only acceptable, but also quite feasible options. Below we will try to understand the issues related to the reduction of fuel consumption on Grants.

Technical aspects provoking an increase in fuel consumption

In recent years, VAZ has made many attempts to improve its own products, however, the number of unresolved problems is also quite large. A whole list of these problems has a direct impact on the amount of fuel consumed. These factors are conditionally subdivided into "hardware" and "software", a similar classification appeared as a result of the use of injection engine and the appearance of a large number of sensors in the design of a car. Now let's dwell on each problem separately.

1. Wrong choice of fuel

Many motorists in our country believe that it is possible to refuel a domestic car with any available fuel. This statement has long roots, but does not reflect the current state of affairs. Any car produced at AvtoVAZ these days is equipped with a variety of electronic systems that require timely care and respect. Naturally, this also applies to the brand of gasoline poured into the tank of his car by the car owner.

According to the official documents of VAZ, Grants must be filled only with A-95 gasoline, since their engine was developed specifically for this brand of fuel. Naturally, such an engine will be able to operate on gasoline with a different octane number, but it will compress it in the same way as the A-95, because this will allow the engine control system to make correct calculations for the production of the fuel mixture. Thus, refueling the car with gasoline with an octane rating of less than 95 will inevitably lead to an increase in fuel consumption.

2. Errors issued by the electronic system

These errors are among the most simple and easily correctable problems, which the owner of the machine can fix at any service center. The reason for their occurrence is the incorrect operation of some sensors involved in the preparation of the working mixture. In such a situation on dashboard the car will light up "Check Engine", and we will talk about violations in the operation of position sensors throttle and mass flow air, as well as a malfunction of the temperature sensors.

A malfunctioning MAF sensor is often associated with contamination and untimely replacement air filter. Since many motorists do not attribute this element to any important detail, little attention is paid to it, and therefore they simply forget to change it in time. However, it is air purification that is one of the determining factors in the operation of a car. Air is the most important component of the working mixture (making up more than 90% of this mixture), and if it is poorly cleaned, then the operation of the engine will be significantly hampered.

But incorrect readings can also be the result of false data received from the oxygen sensor. All this often leads to both the preparation of a lean mixture and the preparation of an overly rich fuel mixture. The result will be either a loss of power or an increase in fuel consumption rates. Diagnostics of all sensors will help to identify a malfunction, while inspection of each of them should be carried out separately.

3. The level of pressure in the fuel system

This malfunction is common and occurs quite often. The pressure can be either too low or too high, but in most cases it is the low pressure that is noted. The malfunction manifests itself in the loss of power by the engine, due to which the driver has to increase the speed when driving the car, which naturally leads to excessive consumption of fuel. And if problems arise with the fuel rail, the car may stop starting altogether.

4. Injector breakage

If the car owner does not follow the engine of his car, sooner or later he will face problems related to its functioning. As a rule, malfunctions arise due to contamination of the injectors, which entails a decrease in the quality of the fuel mixture supply and the engine begins to "triple". The driver's attempt to compensate for this deficiency by increasing the speed will provoke an increase in consumed gasoline.

5. Defective catalyst

Problems similar to those described earlier can arise when the catalyst burns out or deteriorates, which will provoke the preparation of a too rich fuel mixture. This will lead to excessive heating of the catalyst, which will shorten its life and reduce engine power. As a result, gasoline consumption will reach its maximum values.

6. Violations related to engine temperature

Every car owner must timely monitor the temperature of the engine of his car. Remember - at a temperature of 103 C fuel mixture the power unit is greatly depleted and, losing power, is forced to overspend gasoline. A rather tangible problem is the lack of information on the temperature readings of the engine, given to the driver in real time, on the Grants dashboard. Failure to warm up the engine on time leads to the preparation of an excessively rich mixture, which will also lead to an increase in fuel consumption rates by about 20%. Most often, the root of these problems lies in a faulty thermostat.

7. Malfunctions of the motor

Engine deterioration often leads to higher fuel consumption rates. In this case, the car owner has the following symptoms:

• Compression disappears;
• Oil consumption increases;
• The dynamics are deteriorating;
• The motor is unstable and unstable.

Factors that can significantly reduce the operating resource of the motor include:

• Errors made by the owner when choosing an oil;
• Short-term running-in of new car units;
• The engine does not warm up to operating temperature. We need to dwell on this point in a little more detail. Working temperature motor Grants - 90 C, but the overwhelming majority of owners of these cars claim that the temperature rarely rises above 80 C, even when the outside temperature is above zero. In such a situation, the increased risk of malfunctions and poor heating of the car interior are added to the main problem - increased gasoline consumption.
• Contaminated air filter

Failures in the passage of the air flow through the air filter lead to the so-called "oxygen starvation", and its natural result will be high consumption gasoline.

Will the "economical firmware" help to cope with the problem of excessive consumption of gasoline?

Equipping each Grant with a complete set of electrical systems and an on-board computer allows any owner this car Reflash these systems, replacing the settings set by the manufacturer with those that the owner himself considers necessary to activate.

Naturally, such a manipulation is one of the rather risky ones, however, the car manufacturer cannot initially assume in what conditions this or that car will be used. Re-flashing will allow you to significantly reduce gasoline consumption (you can save up to 20%), and if the result does not suit the car owner, he will be able to return to the standard settings without any problems.

It is recommended to replace the original settings with new ones only if the owner has a valid guarantee for the car, and it is better to entrust the carrying out of such a procedure to a qualified professional. If you wish, you can change the settings yourself, but before that you should thoroughly understand all the issues of the specified process.

One of the simplest recommendations for car owners wishing to save on fuel is advice on converting a car to natural gas. This will not lead to a significant decrease in the amount of fuel consumed, but it will almost halve the cost of each kilometer of travel. This option also assumes one drawback - the rapid wear of a number of parts. Note that such a translation will be ineffective in a financial sense for drivers who rarely use their cars.

You can also save on fuel to the detriment of your own comfort when moving - refuse to use all electrical appliances (air conditioner, radio tape recorder, etc.). Such a measure will allow you to save from 0.5 to 1 liter of fuel for every 100 km of run.

Many people think that when moving downhill by coasting gasoline is consumed less, and this is true. But do not forget about the weakening of control over the car during such movement, which is dangerous for both the driver and passengers and pedestrians. In addition, the result of such a ride can be failed brakes.

It is noticed that the movement is close to the heavy by truck reduces gasoline consumption, but this rule only works when the truck in front is moving quickly. At a speed of 50 km / h, movement will take place in a low gear and, on the contrary, gas consumption will only increase.

An important aspect is the tire pressure. At a reduced pressure, fuel consumption will increase due to an increase in the contact zone between the wheel and the roadway, which will complicate the rolling process. Therefore, by increasing the pressure in the tires, you will reduce the amount of fuel consumed by your car. The main thing in this case is not to exceed the parameters recommended by the manufacturer, because a very high pressure will increase the rigidity of movement, in addition, the risk of tire rupture on difficult sections of the path will also increase.

The quality of the fuel you use plays an important role in the economy. Choosing more quality gasoline, you will be able to slightly reduce fuel consumption, however, the high cost of such fuel can offset the possible savings. In addition, drivers wishing to save money on gas are advised to switch to the smoothest driving style and try, if possible, to bypass congested road sections using alternative routes.

Factors leading to excessive fuel consumption

If you leave out the brackets possible breakdowns and car malfunctions, then there will be very few factors provoking high gas mileage. These include driving with permanently on headlights, leading to an increase in gasoline consumption by 5-10%. The same can be said about the quality of the gearbox functioning - if it cannot pull out the required speed, then the fuel consumption, albeit slightly, will increase.

It is not worth saving on gasoline by purchasing low-octane fuel - this will end up with a quick deterioration of some elements of the engine and the gasoline supply system, bringing only additional costs and problems.

Not too obvious reason for excessive consumption of gasoline is poorly adjusted camber. This system is adjusted twice a year, when seasonal shift rubber. Most often, questions arise when the owner of a car chooses a "sports" type of camber, and gaps that are incorrectly set in the spark plugs can also cause problems.

Much also depends on the style of movement chosen by each particular driver - for this reason, fans of abrupt starts and stops should not expect moderate consumption of gasoline. It is possible to save fuel only with a smooth movement, a careful set of speed and a long holding at high rates with a minimum engine speed. It is quite difficult to achieve this result, especially on low-quality roads, but you can still try.

The question is, what is the real fuel consumption for domestic auto Lada Grant is interested not only in representatives of a large category of potential buyers, but also in successful owners who were lucky enough to "taste" all the delights of owning a novelty from domestic manufacturer.

Some "subjects" are satisfied with the consumer qualities of the car, but there are also such individuals who complain about the increased level of fuel consumption, whose words are echoed in support of the testimony on-board computers Frets of Grant.

In practice, there have been cases when the fuel consumption reached a two-fold excess over the norm regulated by the manufacturer. Before "splashing out" angry and offensive remarks to the manufacturer, you should carefully trace the relationship between fuel consumption, equipment level and driving style.

Driving cycle - as a basis for calculating the rate of fuel consumption

The driving cycle of the Lada Grant is a fundamental foundation for assessing the capabilities of a car in the discipline considered here. The role of such a cycle is played by a strictly proportional section of the roadway, during the passage of which the manufacturer's test division registers and then prescribes such parameters and aspects as:

• features of driving style;
• dynamics in acceleration and its intensity in a given area;
• braking distance;
• maximum permissible values ​​of the maximum and minimum speeds.

If Lada Granta passes testing with mechanical transmission, then, in addition, the accuracy and timeliness of switching steps on the same section of the path is taken into account.

Summing up a comprehensive result, the manufacturer positions the consumer the results achieved during the simulated regimes of urban, suburban and mixed cycle fuel consumption indicators.

Based on publicly available information, the fuel consumption of Grants per 100 km of the distance traveled is equal to:

• for city traffic: from 7.1 to 19.6 liters at the maximum, and on average - 11.8 liters;
• extra-urban cycle ( main traffic): from 6.0 to 10.2 liters, which on average equates to 7.6 liters;
• in mixed mode (city-highway): from 7.2 to 14.8 liters, or the average value is 10.3 liters.

Factors influencing the flow rate

The question of what fuel consumption does not have a semantic basis, since it does not take into account a number of important aspects:

• factory level;
• driving style;
• the presence of additionally installed elements (discs with an increased radius, bulky wing and other body kit, etc.).

It is realistic to single out at least six reasons, under the influence of which the fuel consumption per 100 km can "take off" to an unprecedented 20-21 liters.
Such figures, especially for budget car, shockingly affect any owner of the Lada Grant.

The factors considered include the following.

Seasonality

Especially acute increased consumption fuel per 100 km can be observed in the cold season. Together with gasoline, consumption of other fluids of systems and assemblies (oils, etc.) also increases. Have LADA Granta gasoline consumption in this time period can grow up to 2 liters. The main reason (provided that the power system is in good condition) is the need to warm up the engine to frosty temperatures. Indirect factors include movement on ice and the type of tires used (spikes, Velcro, etc.).

Fuel quality

This aspect may affect not only the level of fuel consumption, but also the reliability of the corresponding components. Here, the manufacturer strongly recommends using only 95th gasoline. Exactly given brand, according to numerous observations of owners and experts, as evidenced by many reviews of owners, it can extend the time until the next required refueling. One should not forget the fact that the first and foremost important indicator for fuel is its quality, not quantity octane number... Similar to the proverb: "Check seven times, and refuel once!"
