2017 Audi  SQ7 TDI


Powerful as it is, a turbocharger lags before kicking in; it’s asleep until exhaust builds up to spool its turbine, blasting pressurized air into the engine. The Audi SQ7 TDI uses a 7-kilowatt electric motor to spin its turbine. Inspired by Formula 1, the system hits 70,000 rpm in less than 0.25 seconds. For now, the electric-powered compressor (EPC) is Europe-only. We can’t wait for it to leap the pond. $100,000 (€89,900)
