Den nye Audi R18

Den nye Audi R18 er blevet redesignet helt fra bunden og har næsten intet til fælles med sin forgænger. Den byder på et mere radikalt aerodynamisk koncept og en ny sikkerhedscelle. Dens hybridsystem er for første gang batteri-drevet, V6 TDI-motoren er blevet revideret og nye systemløsninger er blevet tilføjet.

Som resultat er Audis LMP1-sportsvogn blevet endnu mere kraftfuld og – endnu engang – markant mere effektiv end sin forgænger. Til trods for at den nye R18 er den stærkeste til dato, er dens forbrug mindre end tidligere generationers.

Power output of more than 1,000 hp delivered by the TDI and hybrid powertrain, ten percent less fuel consumption than before – Audi is achieving new best marks under the efficiency regulations. The FIA WEC regulations have been providing automobile manufacturers with incentives to build increasingly efficient race cars since 2014.

Starting in the 2016 season, this competition will intensify, as the upper limit for fuel consumption will considerably decrease by 10 megajoules per lap at Le Mans. “The result is a race car that manages energy even more effectively than before. This is an objective we’re pursuing for our road-going automobiles as well,” says Head of Audi Motorsport Dr. Wolfgang Ullrich. “This type of motorsport continues to set an example for automotive engineering. For Audi, production relevance has been a core topic of all racing programs for 35 years.”

 

All development engineers at Audi Sport were challenged to enhance the efficiency of the Audi R18. As a result of switching to the 6-megajoule class, the hybrid system, due to the regulations, now recovers 50 percent more energy. The car’s  aerodynamics concept is fundamentally new. Nearly all vehicle systems have been refined or redesigned. Consequently, energy consumption decreases, the race car has become lighter, and allows for more favorable packaging of the component assemblies. This has resulted in an R18 which even visually clearly differs from its predecessor.
