The race carCadillac V-LMDhwill make its debut later in January at the Rolex 24 at Daytona.
The car features a 5.5-liter naturally aspirated V8 with an internal designation of LMC55R. It also has the common hybrid system that all cars in this class are required to use. The total power output is 670 horsepower (500 kilowatts), which is the maximum allowed by the rules. The engine directs power through a seven-speed sequential gearbox. The chassis comes from Dallara.
The cars competing with Cadillac use forced induction instead of using a naturally aspirated engine. For example, Porsche uses a 4.6-liter twin-turbo V8. BMW has a 4.0-liter twin-turbo V8. Acura chooses a 2.4-liter twin-turbo V6 that revs to 10,000 rpm. Lamborghini will also use a twin-turbo V8.
Cadillac is moving into the new LMDh class after having many previous successes in the IMSA WeatherTech SportsCar Championship. It won the series in 2021, 2018, and 2017. It also recorded wins at the Rolex 24 at Daytona in 2020, 2019, 2018, and 2017.
Cadillac recently announced an entry into Formula 1 with partner Andretti Global. This will be separate from the endurance racing program.
