Following Monday's preview, Audi has taken the wraps off the 2014 R18 e-tron quattro which will have its racing debut on April 20, 2014 in the six-hour race at Silverstone.

Audi says they had to redevelop "every single component" due to the new LMP1 regulations which will be applied starting next year. The vehicle comes with a V6 TDI mid-engine powering the rear wheels and an e-quattro hybrid system driving the front axle.

Audi's engineers have optimized the flywheel energy storage system and worked on the hybrid system which has an electric turbocharger installed within the internal combustion engine.

Compared to its predecessor, the latest version is 30 percent more economical and rides on slimmer wheels. The vehicle has a 1050mm height (20mm taller than before) and its width has decreased by 100mm which has resulted into a slimmer underfloor. It has been fitted with wheel tethers and a carbon fiber reinforced plastic (CFRP) structure behind the transmission which is capable of absorbing energy in case of a collision.

The updated R18 e-tron quattro will participate on June 14-15, 2014 at the Le Mans 24 Hours where Audi wants to repeat this year's success.

Additional details can be found in the press release area.
