Cadillac today announced it is developing a fourth generation Cadillac prototype constructed to the new IMSA and Automobile Club de l’Ouest (ACO) LMDh regulations. The Cadillac LMDh prototype will compete in the IMSA WeatherTech SportsCar Championship and the WEC Championship beginning in 2023.
Cadillac and constructor Dallara are designing the new Cadillac LMDh. The two companies’ cooperative efforts led to the design of the championship-winning Cadillac DPi-V.R. A new GM developed engine will integrate with the LMDh common hybrid system.
Cadillac’s program will partner with Chip Ganassi Racing (CGR) and Action Express Racing (AXR). The Cadillac LMDh will debut on the track for the first time at the Rolex 24 Hours at Daytona in January of 2023, with the objective of participating at Le Mans.
“We are excited to compete at the top level of international motorsport in the LMDh class beginning in 2023,” said Rory Harvey, Cadillac Global Vice President. “Like motorsport, Cadillac is making the transition into a future driven by alternative propulsion. The hybrid nature of the LMDh rules will help us to bridge our technology transfer to our all-electric future. We are excited to carry forward our success and continue to transfer our learnings and technology from the track to our production vehicles. We have had great success with the championship-winning Cadillac DPi-V.R and look forward to building on that record into the future with the next generation Cadillac LMDh.”
“We are looking forward to the new international prototype formula and running the Cadillac LMDh,” said Chip Ganassi. “We have had a great relationship across three different racing disciplines with GM and we are looking forward to developing the car with Cadillac and Dallara over the next year-and-a-half.”
“The IMSA LMDh category is looking to be very competitive with multiple manufacturers,” said Gary Nelson, AXR Team Manager “We’ve had a lot of success running the Cadillac DPi-V.R as one of the original teams since 2017 and we are looking forward to being a part of the next chapter of Cadillac Racing.”
