Why the Bugatti Veyron doesn t use supercharging

From the perspective of fuel economy, there is no turbocharging and fuel saving, because mechanical supercharging is to increase the engine speed to increase the intake pressure of the engine, and the higher the speed, the higher the fuel consumption, but with the increase in speed, the explosive power is not so good. In this era of rampant environmental protection, turbocharging can effectively make the power of small displacement cars beautiful large displacement cars, without increasing the speed, and can increase the power of the engine, so as not to cause large fuel consumption of large displacement cars, outstanding economy, mature technology, and the profits of the car factory are more objective, because turbocharged cars are more expensive to repair and maintain than naturally aspirated (that is, without supercharging) cars, so all things considered, turbocharging is very "practical".

The boost coefficient of civilian turbocharging will not be very high, so the lag caused by low rpm will not be obvious, and it will not be felt at all if you are not careful, such as Passat, Audi A6 and other commonly used engines.

Double supercharging, obviously, with mechanical supercharging to make up for the turbocharging at low speed of the turbo delay phenomenon, and turbocharging to make up for the lack of mechanical supercharging explosive force and make up for each other, so as to better improve the power of the engine, so that the cost is very high, there are also high requirements for gasoline, the quality of domestic gasoline is average, so domestic cars do not have good technology is not good.

Personal opinion, just for reference, because it is a problem, it is impossible to be as comprehensive as in class, I believe you will not be engaged in mechanical supercharging or turbocharging or car design work, so it is enough to understand it, after all, it is really not necessarily a good thing to have too many things in your head. There are many related articles on the Internet, so you can come and study them when you have time.

You have to ask the manufacturer this question.
