Last year, we have reported that Volkswagen has been working on the electric turbocharger for a while. Now, it looks like VW is going to put this new technology in both gasoline and diesel engines.

According to Dr. Ulrich Hackenberg, Audi’s CTO, the upcoming Audi SQ7 will use a brand new diesel V8 engine, with twin electric turbochargers. Audi names this to be “E-Boost”.
By using electric motors to spin up the turbo’s turbine without help from the exhaust gas, the electric turbocharger theoretically has zero turbo lag and it responses to your throttle input instantly. The electric motor supports the turbo until the engine reaches 3,000 RPM: this is because under this situation, the kinetic energy of the exhaust gas is more than enough to spin up the turbine.
We will keep an eye on the new SQ7 and provide you the latest news.
