IMSA and Bosch sign five-year technical partnership

Bosch was already exclusive hybrid powertrain supplier, covering SportsCar Championship and WEC.

The International Motor Sports Association (IMSA) and Bosch have announced a five-year technical partnership.

Confirmed:

  • Rear-wing endplate of all Le Mans Daytona h (LMDh) cars to carry Bosch branding
  • Bosch to provide system engineering, as well as electric motor, inverter, hybrid control unit, and electric braking system
  • Hybrid technology to be awarded to the top three finishing competitors in the LMDh class at the end of each season

Context: LMDh cars compete in both the Grand Touring Prototype (GTP) class of the IMSA SportsCar Championship and the Hypercar class of the World Endurance Championship (WEC). Bosch is the exclusive supplier of the hybrid powertrain in each LMDh car, with the company having a 120-year association with motorsports.

Comment: John Doonan, IMSA president, said: “Our new hybrid-electrified era of IMSA GTP racing would not have been possible without the substantial contributions of Bosch. This is the newest chapter in a decades-long partnership between Bosch and IMSA. We have worked together in lockstep as technology has advanced over the years, and the best is yet to come with our ultimate showcase of relevance, technology and sustainability in the GTP class.”

Coming next: Following the partnership's debut at Sebring, both series return on the same weekend with IMSA at Long Beach on 15th April and the 6 Hours of Portimão in WEC on 16th April.
