The World Endurance Championship unveiled its full provisional entry list for the 2023 season, and a record number of teams will be competing in the top class – with 13 in all contesting the new hybrid Hypercar class, which has replaced LMP1 racers.

And the 1997 World Champion will be heading back into the WEC field for the first time in 15 years, having had two attempts at winning the 24 Hours of Le Mans in the past with Peugeot – finishing second in 2008.
