Endurance racing is the ultimate test for any piece of engineering. Every component from things as big as a pistons to as small as a wheel nut has to function without failing under extreme load for prolonged periods. The Le Mans 24 Hour is arguable the worlds most famous race and this year Porsche return to an event they once dominated. Today it is Audi who rule the World Endurance Championship, but the Porsche 919 Hybrid LMP1 hopes to upset that.
The Porsche 919 Hybrid LMP1 racer complies with the latest regulations that will see this class of car utilise their hybrid systems to a much higher level. The engine in the 919 is a direct injection 2.0 litre turbocharge V4 petrol engine. Revving to 9,000rpm one of the two cars will be piloted by ex-Red Bull Formula One pilot Mark Webber. The new Porsche 919 Hybrid LMP1 is rear driven by the combustion engine, but has temporary all wheel drive when the electric motor is activated to drive the front wheels.
