The front fenders were also lowered in an effort to reduce drag while the concept of air running through the car was abandoned for a more conventional design. The frontal area of the car was redesigned to reveal the raw crash structures. Aerodynamic efficiency was also a major area of focus for 2010. However, despite this, Audi's engineering team led by Ulrich Baretzky were able to achieve engine power and performance that was comparable to the 2009 powerplant. 2010 Regulations reduced the size of diesel LMP1 air restrictors and turbocharger boost pressure. In response to losing the 24 Hours of Le Mans and the Petit Le Mans to the Peugeot 908s, Audi updated their R15 for the 2010 season, creating the R15 plus.

The electrical system uses a lithium-ion battery, a first for Audi sports prototypes, as well as LED headlights, and a unique system of LED rear lights that are mounted on the rear wing endplate.

But they ensure against the risk of aquaplaning. these are based on the design of slicks, except they feature some grooves.As a consequence, grip performance on dry roads is not as good as for slicks. There is an alternative to slicks if you are looking after performance driving on the road: semi-slicks. That is because with no grooves aquaplaning on wet roads happens immediately Using them on wet roads is just sheer recklessness. The tread of a slick tyre is completely slick for unrivalled grip on dry. Slick tyres are exclusively designed for competition.
