Lada Granta has the status of the most affordable passenger car on the Russian market, which promises it good sales volumes in advance. But already in 2022, we will all witness the transformation of the model.
On the page the first details and latest news about the completely new generation of the 2022 Lada Granta model:
- Release date and start of mass production;
- First photos;

Last news
If you don’t turn a blind eye to the price of the new Lada Granta, then the car has quite a lot of disadvantages: the old design of the cylinder block in the engine, the transmission “singing” due to the poor manufacturing precision of the gears, the lack of a subframe, which forces the suspension elements to be attached directly to the body.
All this is the same inheritance that does not allow the model to reach anywhere close to the level of frankly budget foreign cars. The new 2022 Lada Granta promises to take a noticeable step forward, however, all planned improvements boil down to one thing: in fact, the car will become a redesigned Logan.
This will happen due to Granta's transition to the new Global Access platform. In fact, we are dealing with a copy of the well-known budget “trolley” B0, which continues to be used in the construction of Renault Logan, Nissan Tiida, Dacia Dokker, etc. This will already make the new car larger and more spacious, as well as give the opportunity to choose from a wide range inexpensive power plants.
The acquisition of the 2022 Lada Granta will be a serious increase in all aspects: comfort, safety, practicality, efficiency - almost everything will be the merit of a more modern platform, and the exterior will be responsible for the quite successful X-style, which was once developed for Vesta.
Body
Current “family”.
Perhaps the main achievement of the 2022 model year Lada Grant will be the presence of a subframe on which the front suspension with steering mechanism will rest.
This will automatically reduce vibrations and improve handling, giving better steering feedback. The new body itself, most likely, will also be borrowed from Logan, but will receive some of the original stamped parts to give the Russian budget vehicle originality.
Of course, the status of this car in basic equipment will not allow you to count on LED optics, but in the future the Grant will be able to have all the systems and options that the “French” have today.
Salon
New generation salon – Renault Logan.
The new “trolley” will definitely lead to a change in the interior, but it’s not difficult to predict the style of the new design. The Lada-Dacia alliance is unlikely to start inventing something new; rather, the front console from Logan will be transferred to the new 2022 Lada Granta, receiving only spot changes.
It follows from this that in the center of the dashboard there will be a “tower” topped with air ducts, under which a modest multimedia display will be placed. Even lower is a laconic “climate” block.
Obviously, simply transferring interior elements from other “related” models will help keep the model in the segment of the cheapest cars. The only question is which of them will share seats, steering wheel, rear sofa, door cards, etc. with Granta.
Lada Granta 2022 has become more modern
The Granta update is immediately noticeable when viewed from the front, but from other angles and in the interior, the results of the work done are not so obvious. There are many differences, although everything was done with little blood. For example, they didn’t spend money on a new dashboard - they took it from the discontinued Kalina with minimal modifications.
VAZ has modernized the gearbox and parking brake levers. The latter, gleaming with bare metal, needed this especially urgently.
The instrument cluster has been updated to match the latest Lada innovations. Granta now has radial digitization and orange accents. The old-fashioned display with a green background has given way to stylish black and white. The interior lighting is LED, and the lampshade is combined with an emergency call button. They didn’t even forget about the seat upholstery - it now has a different pattern. It seems like a trifle, but against its background the pre-restyling Grant seems like an alien from the distant past.
Technical characteristics and filling
The B0 platform is compatible with a large number of power plants, but the Lada Granta developers are unlikely to miss the opportunity to supply the simplest and most reliable 1.6-liter Renault engines, which can have 82, 102 and 113 hp. With. power. They also provide a decent selection of transmissions (manual transmission, automatic transmission, DSG), which will increase the number of modifications.
In its maximum configuration, the 2022 Lada Granta will be able to have side front airbags, air conditioning, cruise control, power windows, climate control and other comfort systems.
Failure with headlights on Lada Granta 2022
Vesta-style headlights look beautiful, no doubt about it. However, they use lamps with an H19 base. This is exotic even in Moscow, but the lion's share of Grant is distributed throughout the provinces. Where can the owner look for these lamps? In addition, they are noticeably more expensive than the H4, which is sold on every corner and is very familiar to everyone.
In addition to the mistake with the type of lamps, the headlights of the updated Granta have another drawback. They do not shine in the best way, but this is active safety!
Owners of the updated Grant can be consoled by the fact that similarly shaped handles are installed on BMWs of the latest generations - from the relatively affordable “three rubles” to the flagship “X-Seven”.
Release date and start of mass production
The manufacturer promises to show the new Lada Granta in prototype form in 2022. Serial production of the vehicles is expected no earlier than 2022-2023. Initially, the model was supposed to debut in 2021, but due to the global plans of the Renault-Nissan-Lada alliance, production was postponed, but for AvtoVAZ the project of the new Grant is one of the highest priorities and the debut will not take long.
Exhaust system
Grants are equipped with a catalytic converter, which burns exhaust gases, making them less toxic, as well as an exhaust manifold.
The entire structure together is called a catalytic collector. On old Grants it often failed, burned out, and was very sensitive to fuel quality. When it breaks down, and it is expensive, many owners of cars that are not under warranty simply throw it away. They installed a dummy instead, followed by flashing the control unit for Euro-2.
Also regarding the exhaust system, at one time there were frequent complaints about strong vibration of the exhaust system at the moment of starting movement. The culprit was the corrugated insert of the additional muffler, which did not dampen vibrations from the engine. There have never been any problems with the main muffler - it’s an ordinary can, there’s nothing to break.
Model history
Granta in the Sport configuration, which was released in 2011.
The history of the Lada Granta begins in 2011, it was then that the debut of a budget front-wheel drive car under the in-plant index VAZ-2190 took place. The car had a big task; it had to replace the VAZ 2107 (“Seven”), the Lada Kalina sedan and the Lada Samara. The model fully accomplished this goal and became the best-selling model in Russia in 2013, 2014, 2015 and 2019.
At the time of release, the cost of the basic configuration was 229,000 rubles; it is worth noting that all cars came with airbags.
In 2013, the Liftback body appeared, and in 2022 the model underwent restyling, during which it received VAZ’s signature X-Face front end.
Lada Granta 2022 has become more practical
Granta always had everything in order when it came to practicality. Crossover ground clearance, low maintenance costs, a good range of available options - the car retained all these virtues after the update.
A useful addition was the seal along the leading edge of the hood. It is designed to reduce the amount of dirt falling from the road onto the units. Looking at the editorial Grant with a mileage of over 100,000 km, I confidently say: modernization is necessary!
Finally, electric trunk opening buttons have begun to be introduced in Togliatti! Granta didn't have her for seven years.

Main engines
As the main engines, AvtoVAZ offers customers a choice of the power units already mentioned just above. Let's talk about each of them separately.
VAZ-11183-50
The eight-valve VAZ-11183-50 engine is an improved VAZ-2111 with a power of 82 hp, which is installed on Grant sedans and hatchbacks. The work carried out to improve the unit has increased its environmental friendliness and reliability, the level of engine torque and its elasticity have significantly increased.
The disadvantages of the VAZ-11183-50 include increased noise and the need to adjust the valves from time to time. In addition, this motor may not warm up to the required temperature due to a malfunction of the thermostat (the thermostat in such a situation must be replaced).
In addition, instability in the operation of the motor is often observed, for which there may be several reasons. For example, such instability is often associated with the burnout of one of the valves, with a violation of the integrity of the gasket, or with a malfunction of the ignition module. However, bending of the valves due to a broken timing belt will not occur.

Oil seals
A separate story was with the seals. On old Grants, all the oil seals that were installed on the car leaked.
Here are some of them:
- On wheel drives.
- On the gearbox input shaft.
- Front and rear crankshaft oil seals.
- Camshaft seals.
- On the gear selection rod on 12 gearboxes with a traction drive shift.
It was a rare case that the engine and gearbox remained dry. Basically there was always an oil leak somewhere. The situation changed dramatically for the better when Freudenberg Teflon oil seals began to be installed. The defect rate for these seals is almost zero. Therefore, at the moment, leakage defects on new Grants are an extremely rare case.

Test drive of the new Lada Granta: let's figure out who this car is for
If you have been to Russia outside of Moscow and St. Petersburg, you probably noticed a huge number of Lada Granta and Kalina. Ultra-budget models from AvtoVAZ have always been held in high esteem in the Russian outback, but in Belarus they are not accepted as readily as, say, the Hyundai Creta or Skoda Rapid. We are located too close to Western Europe and at the height of motorization we brought a lot of high-quality (and not so good) used cars into the country. In other words, the Belarusian is more demanding in terms of comfort, options and, let’s face it, the car brand than his eastern neighbor. This year, the Russians crossed the Granta and Kalina families into one. They called it Granta. The Onliner.by correspondent went to Tolyatti to admire the Zhiguli Mountains, the Volga River and the X-shaped “face” of the new Lada. Now Granta from certain angles can be confused with Vesta!

Interior
In this regard, Lada Vesta has no competition. Her salon is designed in the spirit of the latest trends. Dashboard wells, poisonous lighting, 3-spoke steering wheel, comfortable seats, well-thought-out ergonomics of the center console, well-placed air deflectors, excellent visibility. All this makes driving Vesta pleasant and comfortable. The spacious and wide rear row guarantees the ability to accommodate three passengers. And if we add to this the significantly increased quality of assembly and materials used, it becomes clear why the sedan became a milestone model for AvtoVAZ.
The inside of the LADA Vesta is simply luxurious.
