Seems Audi is not happy with R8 and want a new supercar to sit above it, and to do so they will build a street-legal Le Mans racer based on the R18, with a diesel engine and an electric motor.
The appearance of the car will be shaped based on the Le Mans race car, including the trademark full-length tailfin, a downsized single frame grille, stacked LED headlights, ventilated front and rear wings, an adjustable rear spoiler, and a relatively narrow canopy-style cockpit accessed through gullwing doors, so it will have a long, wide, and low look like a racing car.

The diesel engine is said to be a twin-turbo V6 producing 550hp, while the two electric motors connected to each of the front wheels will help with 150hp adding torque vectoring, zero-emissions capability, ultimate traction, an on-demand boost effect, and an improved torque curve reaching 1000Nm.
Of course there are no acceleration, top speed, or consumption figures available for now, but we expect the vehicle to do 0 to 100km/h (62mph) in around 3.0 seconds and a top speed of more than 320km/h (200mph).
The hybrid technology allows for staggered brake energy recuperation, high-speed coasting, and a broader start-stop application. Supposedly the car will be shown to the public in 2015 and will begin to be delivered to its buyers in 2017, ready to tackle the Porsche 918 Spyder, the Lamborghini Aventador, McLaren P1 and the Ferrari F70 (codenamed F150).
