Porsche uses four-cylinder hybrid powertrain in new Le Mans car

Porsche has concluded its 2013 test programme with the new LMP1 race car which features the company's recently developed powertrain. Testing will resume in early 2014 in preparation for the World Endurance Championship (WEC) which starts in April 2014, with the Le Mans 24 Hours as the highlight of the season.
The WEC regulations stipulate that manufacturers run hybrid vehicles in the highest class for Le Mans Prototypes (LMP1). Porsche says their hybrid system consists of a four-cylinder petrol engine with direct injection and two energy recuperation systems. The recovered energy is stored in a battery until retrieved by the driver. A powerful electric motor then provides additional drive to the front axle. However, the WEC rules limit the amount of fuel as well as the electrical energy, or so-called boost, available to the driver per lap. The development of such a highly-efficient drive will have positive influences on production development at Porsche.
Wolfgang Hatz, Member of the Executive Board for Research and Development at Porsche AG, said, "We always knew it wasn't going to be easy to return to top endurance racing after 16 years. Hence, our efforts in developing a competitive Porsche LMP1 race car are immense. Up to this point, our engineers in Weissach, the drivers, and the entire team have performed impressively. We are finding new approaches in the development, implementation and application of leading edge efficiency technologies. This also leads to further improvements of the entire hybrid technology in our production cars. Ultimately, our customers will benefit the most."
