The Alpine A424[5] is an LMDh sports prototype racing car designed by Automobiles Alpine and built by Oreca to compete in the Le Mans Hypercar class in the FIA World Endurance Championship.

On 5 October 2021, Alpine formally announced an entry into the FIA World Endurance Championship starting from the 2024 season, using an LMDh-compliant racing design.

[7] Alpine unveiled a prototype show car, named the A424_β (pronounced "A424 Beta"[8]), on 9 June 2023, at the 2023 24 Hours of Le Mans.

It was also announced that the car would use a hybrid powertrain, consisting of a Mecachrome-based V6 single turbocharged internal combustion engine and standardized hybrid drivetrain components provided by Williams Advanced Engineering, Bosch and Xtrac, and that Signatech would run two cars.
