Audi has wrapped up a week-long test at Sebring International Raceway, with the German manufacturer completing significant mileage in its heavily revised R18 e-tron quattro in preparation for the FIA World Endurance Championship season.
All nine factory drivers were on hand for the five-day test last week, which saw the single LMP1 contender complete more than 3,700 miles around the airfield circuit, with a focus on durability.
“All the drivers were enthusiastic about the car,” said Head of LMP, Chris Reinke. “Our Le Mans prototype for this year is an evolution.
“In spite of this, the drivers agreed that they felt improvements in so many areas that you could almost call this a new car.
“The new aerodynamics, for example, in combination with the excellent work of our tire partner Michelin, makes enhanced performance possible.”
Audi has yet to reveal the technical configuration of its 2015-spec model, which features heavily revised front aero and other developments.
Additionally, all four LMP1 manufacturers must declare their hybrid subclass in advance of this month’s Prologue official pre-season test at Paul Ricard.
Porsche, meanwhile, is coming off a five-day test at Motorland Aragon, which saw the debut of its updated aero package. Six of its drivers were on-hand for the test.
