IMSA LMDh: Cadillac and Porsche Testing Together

Ken Zino of AutoInformed.com on IMSA LMDh: Cadillac and Porsche Testing Together

The first race is in late January 2023 at Daytona International Speedway.

Cadillac Racing drivers Sebastien Bourdais, Renger van der Zande, Earl Bamber and Alex Lynn participated in five days of testing last week at Sebring International Raceway in Florida, which followed the initial July 7-8 shakedown.

The all-new Cadillac 5.5-liter DOHC V8 engine developed by GM’s Performance and Racing propulsion team based in Pontiac, Michigan, is paired to the LMDh common or shared  hybrid system. The new race car was co-developed by Cadillac Design, Cadillac Racing and chassis constructor Dallara.

This is where Porsche comes in. The sessions at Sebring International Raceway were the first collaborative LMDh test as Cadillac was joined by Porsche on the track. The cooperation between the OEs during the development of the spec hybrid system will contribute to the success of the broader program, according to GM sports car program manager Laura Wontrop Klauser.

“The collaboration between OEs on the spec hybrid system development has been incredible and has enabled a more efficient timeline for issue identification and resolution,” Klauser said. “It’s great to work closely with those we compete against because we all want to make sure the spec parts are good to go and we can race it out on the track.”

Testing will continue through the year as Cadillac prepares to contest the top category of the IMSA WeatherTech SportsCar Championship and the FIA World Endurance Championship, including the 24 Hours of Le Mans. The first race is in late January 2023 at Daytona International Speedway.
