Porsche officially unveiled today at the 2014 Geneva Motor Show its all-new 919 Hybrid. Set to race in the top LMP1 category of the World Endurance Championship (WEC), which includes the renowned 24 Hours of Le Mans, the Porsche 919 Hybrid is the most complex racecar built by the German carmaker.
919 Hybrid benefits from the know-how that Porsche acquired in producing the 918 Spyder plug-in hybrid super sports car, but also the hybrid versions of the Panamera Gran Turismo and all-wheel drive Cayenne.
Furthermore, just like any other race car, the LMP1 racecar is a unique test laboratory that prepares the technology for future sports cars. The big surprise is found under the hood, where the Porsche 919 Hybrid features a hybrid system that consists of a new 2.0-liter single-turbo V4 direct-injection gasoline engine and an electric motor mounted on the front axle as well as a lithium-ion battery pack.
The new V4 engine revs up to 9,000 rpm and powers the rear wheels, while the electric motor delivers all of its power to the front wheels. The 919 Hybrid also features two energy recovery systems: brake energy recuperation and thermal energy recovery system that is incorporated in the exhaust system.
According to Porsche, the 919 gets an 8 megajoule/lap energy recuperation boost function, the maximum allowed by the current LPM1 rules. 919 Hybrid has an impressive weight of just 870 kg (1,918 lbs) and respects the LMP1 rules in terms of dimensions: it has a length of 4,650 mm, a width of 1,900 mm and a height of 1,050 mm.
