Le Mans Series champion team ORECA will enter its Peugeot 908 HDi FAP in the full Intercontinental Le Mans Cup this year, as it sticks with its title-winning car rather than receiving Peugeot's latest 90X Le Mans contender.
Team regulars Loic Duval and Nicolas Lapierre will form ORECA's main driver lineup this year.
ORECA's technical director David Floury said sticking with the 908 gave the team a better chance of hitting the ground running at the start of the season.
"A new car would have meant a later delivery date," he said. "To arrive at Sebring under the best conditions, we are conducting several tests in 2011 configuration, with the new restrictors and boost pressure. As for the 24 Hours of Le Mans, with the change in regulations we are aiming for reliability more than pure performance."
Contesting the ILMC means ORECA will return to the Sebring 12 Hours for the first time since it won the GT class with its Chrysler Viper in 2000.
Team boss Hugues de Chaunac said: "It's always with great pleasure that we cross the Atlantic. We especially appreciate the American way of racing and we are excited to once again enjoy the special, even legendary, atmosphere of Sebring."
