Despite the fact that the Lada Granta is a budget car, the manufacturer offers a wide range of engines for it:
- VAZ-11183-50;
- VAZ-11186 (VAZ 21116);
- VAZ-21126;
- VAZ-21127;
- VAZ 21126-77.
Of course, the volume of the engines listed above is approximately the same and is 1.6 liters, but each of the listed power plants has its own advantages and disadvantages. For this reason, many car enthusiasts who want to purchase a Lada Granda often cannot decide on the type of engine they need, and therefore below we will try to consider each of them.

A selection of accessories for LADA from AliExpress
If you buy a Lada Granta car, which engine is better to choose? This question interests many future car owners. Every buyer wants to purchase a maneuverable, powerful, controllable and fast car. And not everyone has the desire to do engine chip tuning.
The domestic automaker produces a grant with 5 types of engines. Not every driver knows which engine to choose, since Grant engines differ from each other not only in their advantages, but also in their disadvantages. Therefore, when choosing, it is better to immediately evaluate all the pros and cons.
Machine equipment
In the basic configuration, the client will receive several airbags, LED headlights, stability control, anti-lock braking system, a multi-adjustable seat, climate control, an audio system, fabric upholstery, an alarm, a spare tire, power windows and 13-inch wheels. For all this you will have to pay about 400 thousand rubles. which is not very much.
As for the top version, you can see central locking, electric power steering, rain and dust sensors, heated seats and front mirrors. Of course, all this will cost a little more, but you will enjoy it and feel comfortable while moving. The manufacturer provides a three-year warranty.
16 valve Lada Granta engines
Progress does not stand still. Therefore, 16-valve engines became the basis for most modern VAZ cars. Let’s make a reservation right away that on all 16-valve Granta engines the timing belt breaks, so we recommend that you take the issue of replacing and diagnosing it seriously. Read more about replacing the timing belt on a 16-valve engine here.
If you are the owner of a 16-valve engine, then these articles will be useful to you:
Engine 21126
Engine 21126 under the hood of Grants
A less powerful 16-valve engine for the Lada Grant is model 21126, which was developed nine years ago. In fact, this power unit can be called a logical continuation of the VAZ-21124 line. Experts consider this motor as one of the most reliable and high-quality in the entire model range of the domestic manufacturer.
Its power reaches ninety-eight horsepower, with a maximum engine speed of 5600 rpm. The torque will not be so impressive, amounting to only 145 Nm at four thousand rpm.
Some Grant drivers note difficulty starting the engine at subzero temperatures.
At one time there was a story that if the temperature is below -27 degrees, the ECU will not allow the engine to start. This turned out to be untrue. Read more about where the ECU is located here.
Engine life
The engine life will be equal to two hundred thousand kilometers.
It is also worth noting that the compression ratio in the cylinders will be equal to 11. All these positive qualities, including reduced fuel consumption in the extra-urban cycle, have led to some troubles.
The valves are bent!
We are talking about an increase in fuel consumption when driving around the city up to 9.8 liters , and also about the fact that when the timing belt breaks, what everyone is so afraid of happens - the valves bend.
Engine 21127
The second version of the 16-valve engine is the same 1.6-liter 21127, which was developed only three years ago. It boasts a maximum power of 106 horsepower, a torque of 148 Nm at four thousand revolutions, and an average fuel consumption of seven liters in the combined cycle.
Engine life
The engine life is limited to 200,000 km.
Positive points
Experts note such positive aspects, in comparison with the predecessor VAZ-21126, as greater engine thrust at the “bottoms”, which leads to noticeable changes in operation.
The valves are bent!
But the shortcomings remain the same. We're talking about bent valves when the timing belt breaks.
What engines are used on the Grant?
- In the standard version, Granta comes with a 1.6 liter power plant. The eight-valve engine develops power up to 82 hp. With.
- In the standard and luxury trim levels there is a 16 valve unit, the power of which is 98 hp. With.
One of the popular car modifications is sport. The main difference between the power plant is the presence of a lightweight connecting rod and piston group. The gas distribution system was changed, which allowed engineers to increase power to 120 hp. With. This is an aggressive modification of the car, adapted for fast and extreme movement.
- As standard, Lada Granta comes with a five-speed manual transmission. The system has been intelligently modernized. The changes also affected the gear selection mechanism of the torso drive, as well as the synchronizer.
- Later, configurations with a four-speed automatic transmission and a five-speed robotic transmission appeared. Moreover, it is interesting to note that the machine was installed at the factory directly on the assembly line, which was a new product for the domestic manufacturer.
Malfunctions, causes, elimination
The first drawback of Lada Granta engines, as already mentioned, is the bending of the valves when the belt breaks. To avoid this malfunction, it is necessary to change it in time and visit service centers for maintenance. Then the valves will not bend, since the updated belt will last for another 100 thousand kilometers.
Young people are trying to tune the power units of cars produced by the Lada Granta plant. This includes increasing engine power. To do this, they do chip tuning, that is, they program the electronic brains of the engine, or install a turbocharger. All this leads to the rapid depletion of the engine’s vital reserves and affects its operation. A tuned engine loses 50 thousand kilometers, which it would have covered if it had been left aspirated. And that's the minimum.
Other problems are hidden in the malfunction of hydraulic valve lifters. This is also a common malfunction that car owners have to deal with. This can only be solved by installing new hydraulic pushers.
Forgetting to regularly replace filters leads to system contamination. Crumbs from used engine parts appear and travel through the oil system. It acts as an abrasive on the pistons and wears them out. The solution to this problem is to regularly replace the filter elements, especially for oil and fuel filters.
The knocking sound of the crankshaft main bearings is a concern for car owners. In this case, you need to make sure that the oil pressure in the engine is normal. Tighten the flywheel mounting bolts.
If everything is fine with the bolts and oil, then you may have to replace the crankshaft bearings or grind the journals, or reduce the clearance in the thrust bearing. As a last resort, replace the crankshaft.
Reviews from car owners about the 87 hp engine.
Most reviews are positive.
Mostly problems occur due to low-quality fuel and lubricants. The engine may start to stall and run intermittently (floating idle, stalls, loss of power, etc.). In this case, the “Check Engine” malfunction icon (indicator) should light up on the instrument panel.
The engine pulls well at low end; on the highway, even with a full load, there is enough power. This is especially noticeable when compared with a Ford Focus automatic: engine capacity 1.6, power 100 horsepower. Granta drives more fun, Focus “deflates” after 80 km per hour. As for Focus - personal experience, I owned just such a car.
Fuel consumption
Even in a mixed cycle with traffic jams, consumption will not exceed 10 liters per hundred!
Fuel consumption is good. Even in a mixed cycle with traffic jams, consumption will not exceed 10 liters per hundred. My consumption is 8 liters in the city, 6 on the highway. This is on 92 gasoline. I checked from tank to tank, it roughly matches the readings of the on-board computer. On 95 gasoline, which is what AvtoVAZ recommends using, fuel consumption should become even less.
Read more about car consumption in the article: passport and real data on fuel consumption.
If your consumption exceeds the norm, then you need to look for a malfunction. Do not delay troubleshooting, as your engine may be overloaded.
Starting in the cold
In cold weather it starts, even after a long stay. The main thing is a good battery, a working fuel pump and power system.
If your car does not start, then this article will help you.
Basic motor: brief technical overview
The power of all installed motor modifications differs slightly. It should be noted that versions 11186, 21116 are only 7 liters. With. stronger than the modification with index 11183. It was possible to increase engine power through the use of a piston group that was 39% lighter, which also had a positive effect on fuel consumption. This is partly due to the greater elasticity of the motor and some increase in torque. A small increase of 20 Nm allows you to switch less in traffic, and accelerate from any speed after reaching a value of 1500.
Engine 11183 is now installed only on the Lada Kalina; this car is still somewhat lighter.
As noted, engines 11186, 21116 for the Lada Grant have a rather modest appetite. The average fuel consumption indicated by the factory is 7 liters; in road conditions the figures are similar, usually 7.5 l/100 km with working power and ignition systems. For comparison, according to the passport, the engine with index 11183 fits into 7.2 liters in the combined cycle, which is 0.2 liters more.
All of the mentioned engines have a gas distribution mechanism with 2 valves on each cylinder, which has not been a sign of engine perfection for a long time. However, here the main emphasis should be on structural reliability and excellent engine life, since the engines do not experience extreme overloads and are able to operate for a long time without failure.
Engines 11186, 21116 are four-stroke, with distributed fuel injection and overhead timing gear parts. The main technical parameters are:
- working volume - 1593 cm 3;
- torque - 140 Nm when reaching 3800 rpm;
- acceleration to 100 km/h - 1.5 seconds;
- maximum speed - 166 km/h;
- connecting rod and piston group - Federal Mogul;
- Timing drive - belt, with automatic tensioner;
- pistons are cooled using special oil nozzles.
The start of operation of the Lada Grant showed that the dynamics and traction characteristics with the installation of such engines, although improved, still remained average, which forced owners of AvtoVAZ products to modernize their vehicles.
Description
The Grant engine is a modernized version of the long-produced engines 21124 and 11183. It differs from its predecessors by the presence of a 39% lighter connecting rod and piston group developed by Federal Mogul. For the VAZ-11186 engine it is manufactured directly at AvtoVAZ OJSC.
As a result of the modernization, significantly:
- power increased;
- exhaust toxicity has decreased;
- fuel consumption has decreased.
The cylinder head has become much stronger, since during manufacturing it undergoes a special heat treatment cycle. In addition, it is further strengthened by metal gaskets.
Despite the fact that all the motors in the line are assembled according to an identical design, the 11186 engine has a number of design features. Among them are:
- Improved cooling system for the block and cylinder head. The piston group is covered with a cooling jacket along its entire height and is equipped with piston cooling nozzles, which prevents deformation of the cylinder block due to uneven heating.
- Using a new camshaft drive design equipped with an automatic tensioner.
- The original design of the crankshaft, equipped with special oil channels, which are closed with plugs. This required the use of high-strength cast iron for its manufacture.
A significant drawback of the grant engine is that if the timing belt breaks, the valves bend, which can lead to failure of the power unit as a whole (breakage of pistons and cylinders). In order to protect the engine, a highly reliable drive belt is installed at the manufacturing plant during assembly, which is manufactured by the American company Gates Rubbler Company. The service life of this belt is at least 200 thousand kilometers.
Interesting: As a result of modernizing the VAZ-11186 engine, it became possible to equip it with an electric throttle valve drive (E-gas). This allows you to increase its power to 90 hp. With.
