Ex-Formula One drivers Johnny Herbert and Allan McNish have joined Audi UK's
2004 sportscar line-up.
Herbert won four times in the American Le Mans series last year
The Team Veloqx-run Audi UK squad will run two cars at the Le Mans 24 Hours
and in the inaugural four-race Le Mans Endurance Series.
The pair will join English trio Jamie Davies, Darren Turner and Guy Smith - a former Le Mans winner - along with Germans Pierre Kaffer and Frank Biela.
"Le Mans glory won't be easy - we must fight hard for wins," said McNish.
The Le Mans Endurance Series consists of 1000km races at Silverstone, Monza, Spa-Francorchamps and Nurburgring.
Former Audi driver McNish, who raced in F1 for Toyota in 2002 and was Renault's test driver last year, won the 1998 Le Mans 24 Hours in a Porsche.
He is relishing the chance to drive the Audi R8, which has won three of the last four titles.
"I had a very successful and happy time when I was with Audi previously while Le Mans is a very special race and dear to my heart," said Scotland's McNish.
"The Audi R8 has been further developed since I raced one and is an outstanding sportscar."
Essex's Herbert won three Grands Prix in his F1 career, won Le Mans in 1991 for Mazda, and clinched four victories for Audi in the American Le Mans Series last year.
The 39-year-old will only compete at Sebring and Le Mans.
He said: "We'll be up against two similar Audis at Le Mans run by American and Japanese teams so it will be tough but I have every confidence and am looking
forward to the challenge."
The sportscar season kicks off on 20 March in Florida when Sebring hosts its 12-hour race, traditionally the first pointer as to who will do well at Le Mans title.
