This weekend's Le Mans 24 hours will feature twenty-two former F1 drivers among those entered for the classic French race.

Best placed to win the event is former Toyota F1 driver Allan McNish, and former Minardi and Williams driver Marc Gene, who race for the factory Audi team, the outright favourite for the event, having won the previous two years running.

Toyota's lineup includes Alexander Wurz, Kazuki Nakajima, Anthony Davidson, Sebastien Buemi and Stephane Sarrazin.

Nick Heidfeld, Stefan Johansson, Martin Brundle, Giancarlo Fisichella, Sebastien Bourdais, Franck Montagny, Shinji Nakano, Jean-Christophe Boullion, David Brabham, Karun Chandhok, Jean-Denis Deletraz, Gianmaria Bruni, Olivier Beretta, Jan Magnussen and Pedro Lamy are the other F1 driver's participating in this year's event.

Brabham, Gene, McNish, Wurz, Johansson and Brundle are all former winners of the race.

A number of F1 world champions have gone on to win the race outright - Mike Hawthorn, Phil Hill (3 times) and Jochen Rindt - but none in recent times.
