For 2003, Bentley decided that their new evolved Speed 8 would need competitive testing in order to prepare for an overall win at Le Mans. The pair of new cars were therefore entered in the American Le Mans Series 12 Hours of Sebring. Despite having to start at the back of the field due to a rules infraction in qualifying, the two cars quickly made their way through the field. The Bentleys were able to take third and fourth places, behind the factory and a privateer R8.
