To mark the 25th anniversary of their TDI diesel engines, Audi launched a concept model based on the RS5 Coupe, powered by a very special V6 TDI engine. This car is a showcase of the fact that diesel engines can be hugely powerful while remaining fairly economical.
The TDI unit powering the Audi RS5 TDI Concept is a twin-turbo 3.0 liter V6 featuring equipped with an additional electric turbocharger. Theoretically, the electric turbo (E-Lader) force feeds the engine until the conventional turbos build up enough boost to take over, thus eliminating the turbo lag.
Using this system, Audi engineers have managed to extract 385 horsepower and 750 nm of torque. Those numbers seem especially impressive when you realize the average fuel consumption is under 5 liter per 100 km.
Performance-wise, Audi RS5 TDI Concept accelerates from 0 to 100 km/h in about 4 seconds, and it can reach a top speed of 280 km/h. The car has its eight-speed automatic transmission and quattro all-wheel drive to thank for this.
Audi has no plans to launch a diesel-powered RS5, but the technology used in this engine could be utilized for other production models.
