In the corporate channel “Weave with LADA” tried to explain the lack of boiled engines. AvtoVAZ identified three reasons why power units with a turbocharger are not installed on LADA cars from the plant. Firstly, the features of the legislation of Russia. Secondly, the complexity of the design and the high cost of such motors. Finally, in the range there is no suitable model yet.
In Russia, the tax is calculated based on the engine power, while abroad the rate is tied to the working volume. Therefore, our “small” turbo engines did not become massive. AvtoVAZ believes that abroad “a wave of interest in small -scale turbo engines gradually decline”, since in practice the benefits of fuel and ecology consumption were not confirmed.
The second reason is the complex design of turbo engines and their exactingness to the quality of the service and spare parts. In addition, you can’t just make a turbo engine from the “atmospheric”: engineering experience shows that you need to completely “shove” the base engine, change materials, lubricant, cooling and ventilation. The cost of the turbo engine is at least 50% higher than that of the “atmospheric”, and they do not see a massive request for such units at AvtoVAZ.
The latest Niva, Minivan and B-Cross: what was shown to Putin on AvtoVAZ AvtoVAZ called the minimum resource of Lada engines, the equipment, filling and the price of the cheapest Lada ISKRA are disclosed
Also, under the turbo engine, you need an appropriate car. Under the increased power, it is necessary to seriously finalize the design: gearbox, suspension, brakes, cooling system. As a result, a turbocharged car will be more expensive. Now there is no suitable model in the LADA line. The situation of the first generation of “atmospheric” 1.8 is repeated: for “Priora” and “Kalina” from “big”, and for Lada Vesta came to the court.
The engine with a capacity of 145 horsepower from Lada Vesta Sport for mass cars has not been created: it is produced piece and for the family sedan “will be alien”. The high-cost unit hopes to return to the conveyor this year, replacing the French 5-speed “mechanics” with a Chinese 6-speed transmission. And on ordinary AvtoVAZ models, modernized “six” will appear.
