Audi motorsport division is saluting Porsche’s highly anticipated return to Le Mans which will take place on June 14 and 15. It’s been a huge 16-year hiatus for Porsche but now they are officially back in the game with the 919 Hybrid which will have to go up against Audi’s R18 e-tron quattro. It’s interesting to see Audi and Porsche on the Le Mans grid taking into account both automakers are part of the Volkswagen Group.
In previous articles we’ve extensively talked about the 2014-spec Audi R18 e-tron quattro so we shall focus on the Porsche 919 Hybrid which will use a direct-injection V4 single-turbo gasoline engine working together with an electric motor mounted on the front axle and with a lithium-ion battery pack. The special V4 engine can rev up to 9,000 rpm and powers the rear axle while the electric motor propels the front wheels.
Thanks to this configuration, Porsche’s Le Mans racer has temporary all-wheel drive and benefits from two energy recovery systems (brake energy recuperation & thermal energy recuperation). Needless to say, the 919 Hybrid meets the most recent LMP1 regulations so it weighs a minimum of 870 kg and its dimensions cannot exceed 4650mm length, 1900mm width and 1050mm height.
The Audi motorsport division will face the fierce competition coming not only from Porsche, but also Toyota’s TS040 Hybrid which uses a 3.7-liter V8 gasoline engine and a four-wheel-drive hybrid system providing the Le Mans racer with a combined output of no less than 1,000 bhp
