The Alpine A424 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.

The car is built on the “next generation” Oreca LMP2 chassis. The A424’s engine is said to be a “heavily modified” version of the Mecachrome V634 engine used in the FIA Formula 2 Championship; Alpine confirmed that the car’s engine was unrelated to the engine briefly used in the Ginetta G60-LT-P1 LMP1 car in 2018. Dyno tests for the engine were completed on 28 June. The car was first fired up on July 5. The program first completed 2 shakedown tests at Lurcy-Lévis at the end of August. The test programme then continued running at Circuit Paul Ricard, Motorland Aragón, Jerez and Portimão.
