Welcome to one of the race events of the year, the 24 Hours of Le Mans. Up front we all expect Audi to win but in qualifying Toyota were also quick - will either hybrid design be reliable enough to last the distance? The same question can be asked of the unique Delta Wing experiment which has suffered electrical gremlins so far this week, fingers crossed those problems are solved. Away from the technologically interesting cars we do actually have some close races! Watch the 'independents' fighting tooth and nail to finish as best behind the manufacturers - they might even take a few big name scalps. Behind them, the LMP2, GT Pro and GT Am classes are wide open and you can't pick a winner in any of them. 24 hours. 56 cars. 168 drivers. Boring? Not on your life.
