Cadillac have confirmed that 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 FIA WEC 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.”
2023 then should see the Cadillac brand return to Le Mans for the first time since 20o2 when the factory team completed a three-year LMP programme with the single season Northstar LMP 02 (above).
IMSA President John Doonan: “Cadillac’s decision to continue its successful IMSA prototype program further validates the LMDh platform,” Doonan said. “The combination of cost-effectiveness, technical relevance and the ability to compete for overall victories in the world’s most important endurance races has clearly resonated with five manufacturers so far, with even more expected in the future.
“Cadillac already owns a tremendous legacy in sports car racing, especially over the past four years in the WeatherTech Championship,” Doonan added. “If the launch of Cadillac’s DPi program in 2017 is any indication, we’d expect that the new Cadillac LMDh prototype will be a top contender right from the first race at Daytona in 2023.”
