Audi is already at work testing next year’s LMP1 hybrid Audi R18 e-tron quattro race car a week after the World Championship winning Audi R18 e-tron quattro racecar’s ran its last race.

Tests of the new LMP1 sports car, which has been kept under wraps up to now, start today on the U.S. Sebring race track, in Florida.

Audi Sport in Ingolstadt and Neckarsulm developed jointly a fundamentally new Le Mans prototype, said Audi, that respects new 2014 Technical Regulations and is designed for maximum efficiency. The development started in 2012 and today, the next-generation Audi R18 e-tron quattro is being tested on the race track where all new Le Mans prototypes of the Audi brand have been tested.

“We’ve reached a crucial stage in this project,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “After building the first prototype, testing on various race tracks is now taking center-stage. The tests are mainly focused on achieving high mileage, coordinating the highly complex hybrid drive systems and working out an efficiency-optimized total package that has never before been as complex as this one.”

Audi has won the manufacturers’ and drivers’ classifications in the FIA World Endurance Championship (WEC) for the second time in a row and the Le Mans 24 Hours for the twelfth time this year.

Audi stated it will present the next generation of its hybrid sports car and announce further technical details before the end of December.
