Motorsports remains a key platform for General Motors to hone engineering and leadership skills in a fast-paced, highly competitive environment and make the company stronger.
For 2025, Cadillac Racing has expanded its Grand Touring Prototype lineup to three entries for the nine-race IMSA WeatherTech SportsCar Championship season and increased its FIA World Endurance Championship lineup to two Hypercars for the eight-race season.
To further support its IMSA and WEC programs, GM Motorsports is rolling out a new Cadillac Racing leadership structure. The moves reflect the level of resources and investment that GM is making in its global motorsports initiatives.
The Cadillac Racing leadership team includes the additions of a technical director and propulsion manager.
