I have filmed the incredible 2014 Audi R18 e-Tron Hybrid Quattro LMP1 during a private test day at Monza circuit. This will be the next Audi which will participate at the 2014 24 Hours of Le Mans in the LMP1 category (Le Mans Prototype 1).
It's powered by a Turbocharged V6 DOHC TDI engine which is able to produce 510HP and over 850NM of torque, but thanks to its light weight and aerodynamics, can easily reach a top speed of over 340km/h.

 

The audio seems a bit "bogus", very last scene it sounds like the car is still accelerating after an upshift into a curve and the brake lights have come on..
