LMDH prototype starts testing

Porsche’s LMDH prototype – its next Le Mans challenger – takes to the track

Testing of the latest Porsche endurance racer, designed for the new LMDH prototype racing category, has begun. The new challenger will start racing in 2023 and aims to win the world’s biggest FIA WEC World Endurance Championship races, such as the 24 Hours of Le Mans, Daytona and Sebring.

Engine regulations for the LMDH category provide freedom in terms of displacement, design and number of cylinders. However, revs are capped at 10,000rpm and drive-by noise can’t exceed 110 decibels. The Porsche hybrid machine is fitted with a large-capacity twin-turbo V8 engine that runs on renewable fuels. Some of its other parts are supplied by Williams Advanced Engineering (battery), Xtrac (transmission) and Bosch (motor-generator unit and electronics). In race trim the hybrid drive system produces around 680PS (500kw).
