The 24 Hours of Le Mans, the 77th Grand Prix of Endurance, is the world's oldest endurance sports car race. Danish native Tom Kristensen has won a record eight races including last year's and six-straight from 2000-2005. Kristensen and teammates, Rinaldo Capello from Italy and Allan McNish from Great Britain, will be racing the Audi R15 TDI for Audi Sport Team Joest. Kristensen has won six of his titles behind the wheel of an Audi.

"The 24 Hours is truly a one-of-a-kind event, testing both the high performance technology of the race cars and the endurance of the drivers and their teams," said Scott Greenstein, SIRIUS XM Radio's President and Chief Content Officer. "With satellite radio, SIRIUS and XM listeners have the benefit of being able to hear every minute of the race anywhere, at home or on the go."

"We have always enjoyed great support from U.S. based enthusiasts," said Eve Hewitt, Managing Director of Radio Show Limited, the team behind Radio Le Mans. "Broadcasting our Le Mans programs through SIRIUS XM makes perfect sense."
