Audi Sport UK Team Veloqx triumphed in the Sebring 12-Hours race in Florida, with Frank Biela, Allan McNish and Pierre Kaffer in the winning car.
The experience of Biela and McNish boosted Veloqx
Biela handed over to Kaffer with a less than 90 minutes left and Kaffer went on to win by five laps.
The "sister" Veloqx Audi R8 of Jamie Davies, Johnny Herbert and Guy Smith was third behind an ADT-Champion Audi.
It was Audi's fifth straight Sebring triumph, tying them with Porsche for the most consecutive wins.
Audi has dominated the American Le Mans Series, winning four drivers and manufacturer titles in five years.
The win also is Biela's third, tying him with Mario Andretti, Phil Hill, Hans Stuck and Olivier Gendebien.
Kaffer held a 5.7-second advantage over Guy Smith at the halfway point, even though he was forced to pit for minor body damage repairs after a clash with a GT class Porsche.
The Veloqx team needed only 20 seconds to replace the
entire rear-body work on Kaffer's car, but the delay was
enough to allow Smith to take a short-lived lead.
But Kaffer needed only a few laps to close the gap and overtake Smith for the top spot overall.
The pole-starting ADT-Champion team ran into early trouble when defending series and race champion Marco Werner tried to overtake two backmarker GT class Porsches.
"One overtook the other and I followed the first one, and
then the other came from the outside and hit me from the rear," he said.
The damage needed extensive repairs, which gave Team Veloqx Audi too much of a cushion.
Kaffer declared himself "overjoyed" at winning in what was a triple debut - for Audi, at Sebring and over long distance.
Former Toyota Formula One driver McNish, back with Audi after failing to extend his F1 career, said: "Coming back and scoring this victory is amazing."
