Porsche's new LMDh prototype will compete for overall victories in the world's biggest endurance races at Le Mans, Daytona and Sebring from the 2023 season.
The car will compete in the FIA World Endurance Championship and the North American IMSA Championship under the team name Porsche Penske Motorsport. The testing program has just started in preparation for the race premiere in January 2023.
V8 engine with bit turbocharging
In its choice of combustion engine to complement the standard hybrid elements specified by the regulations, Porsche has opted for a large-volume V8 power unit with bit turbocharging. The engine is designed to run on renewable fuels. The system output of the hybrid drive is around 500 kW (680 hp) in the race.
Thomas Laudenbach, Head of Porsche Motorsport: "We were spoilt for choice when it came to selecting the engine for our LMDh prototype, as the product range offers several promising basic units."
Many freedoms for the designers
The engine regulations for the LMDh vehicle class allow great freedom in terms of displacement, design and number of cylinders. The maximum speed is 10,000 rpm, the maximum pass-by noise 110 decibels. The engine, including air intake and exhaust tract as well as peripheral components for cooling, must weigh at least 180 kilograms, and maximum power must be in the range between 480 and 520 kW (653 and 707 hp).
The unit components for recuperation, storage and delivery of electrical energy are from Williams Advanced Engineering, Bosch and Xtrac.
