Bosch and IMSA Announce Long-Term Partnership

Rear Wing Endplate of All LMDh Race Cars Competing in IMSA GTP Class Feature ‘Hybrid Electrified Bosch’ Branding

  • Bosch continues its 120-year commitment in motorsports with new agreement with IMSA
  • Relationship extends beyond sponsorship as Bosch is a fundamental technology collaborator for IMSA series
  • Bosch provides system engineering as well as electric motor, inverter, hybrid control unit and electric braking system for new LMDh technology in IMSA
  • LMDh hybrid system developed for scalability to meet the needs of evolving propulsion technology

SEBRING, Fla. – At the Mobil 1 Twelve Hours of Sebring, Bosch and the International Motor Sports Association (IMSA) announced a five-year corporate partnership to further leverage Bosch’s electronics and mobility expertise to enhance vehicle performance, improve safety and create a more equitable and robust racing experience.


As the motorsports industry embraces sustainability and conservation of resources, Bosch is accelerating the development of components and systems for electrified drives that supplement the portfolio of components and services for conventional internal combustion engines. A prime example is the new Le Mans Daytona h (LMDh) vehicle -North America’s first hybrid-powered prototype race car that competes for overall victories in IMSA’s Grand Touring Prototype (GTP) class. Bosch Motorsport is an exclusive partner for the hybrid powertrain in each LMDh car. This new Bosch-IMSA partnership helps bring Bosch’s technology and data to life for customers, fans and stakeholders around the world.


“Bosch has played a passionate role in motorsports for more than a century. From our ABS systems allowing for unbeatable braking performance, to our collection of electronics and telemetry systems that allow for data driven performance on and off the track, to our new LMDh technology for electrified racing, Bosch helps set that pace,” said Jacob Bergenske, director of Bosch Motorsport, North America.

“Our new hybrid-electrified era of IMSA GTP racing would not have been possible without the substantial contributions of Bosch,” said IMSA President John Doonan. “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.”

Additionally, under the partnership agreement, hybrid technology will be awarded to the top 3 finishing competitors in the LMDh class at the end of each season.


Bosch Motorsport Helps Power IMSA

After a successful debut at the 2023 Rolex 24 At Daytona earlier this season, the new LMDh vehicles are set for their second race at the Mobil 1 Twelve Hours of Sebring. Bosch is the official systems engineering lead for the hybrid system which features high-cost efficiency due to standardized parts, enabling vehicle manufacturers and teams to compete under attractive conditions at endurance classics such as Le Mans, Daytona or Sebring.


The hybrid system is flexible and can be combined with different vehicle and engine concepts, while still offering a high level of performance. Per current LMDh regulations, the system in drive mode delivers a permanent output of 50 kW, and up to 200 kW in recuperation mode. However, the hybrid system has been designed for scalability and is capable of higher levels of performance, enabling Bosch to meet the ever-evolving power and torque demands of racing.
