Motor Trend had the chance to test drive the Audi R18 e-tron in Italy at the Misano circuit. Behind the wheel was MT’s resident racer Randy Pobst who had the opportunity to take last year’s Le Mans overall winner for a quick ride, a race car which has an estimated value of no less than $30 million.
We remind you the car is motivated by a V6 TDI mid-mounted engine which power the rear axle and works together with a front-mounted ERS-K – Energy Recovery System Kinetic to enable the R18 e-tron provide a quattro hybrid setup. The system also benefits from an electric turbocharger installed in the internal combustion engine called ERS-H – Energy Recovery System Heat which stores the energy converted from the heat.
There’s also a Motor-Generator-Unit (MGU) which recovers kinetic energy at the front axle during braking and that energy flows into a flywheel energy storage system. A novelty of the 2014 Audi R18 e-tron was the connection between the turbocharger of the internal combustion engine to an electric machine which allowed the thermal energy of the exhaust gas to be converted into electric energy. During acceleration, the stored energy can flow back into the MGU at the front axle or it can be transferred to the electric turbocharger.
