Bosch has secured a major contract from Mercedes-Benz to supply electric motors for the automaker’s next generation of electric vehicle drive systems through the 2030s.
The agreement covers the production of electric motors across multiple power classes, though Bosch did not disclose financial terms or specific production volumes.
Unlike some of Bosch’s other electric vehicle supply contracts, the deal does not include fully integrated e-axle systems combining motors, transmissions and power electronics.
Instead, Mercedes-Benz will integrate Bosch-supplied electric motors into its own proprietary drive units.
The German automaker is already using a similar strategy in vehicles such as the all-electric Mercedes-Benz CLA, where the company’s ATS 2.0 rear-drive unit is paired with an externally sourced front electric motor in all-wheel-drive variants.
For Bosch, the contract represents an important win as the supplier continues to expand its electrification business amid restructuring and workforce reductions tied to declining combustion-engine demand.
Markus Heyn, executive director of Bosch and chairman of Bosch Mobility, said the agreement reflected the companies’ long-standing relationship.
“The new order reaffirms our long-standing partnership with Mercedes-Benz and shows that we can successfully contribute our expertise to technologically demanding projects as well,” Heyn said.
Bosch said its electric motors achieve efficiency levels of up to 98%, supported by a newly developed winding technology designed to improve power density while reducing overall weight.
The company also highlighted its rotor oil-cooling system, which is intended to improve thermal management and performance under high-load conditions.
According to Bosch, the electric motor platform is scalable, allowing different motor lengths and power outputs to be adapted for multiple vehicle and axle configurations.
The supplier said its portfolio includes electric motors delivering up to 500 kilowatts of power and up to 1,000 Newton metres of torque, operating across voltage architectures ranging from 400 to 850 volts.
Bosch said it currently supplies electrification technologies and components to more than 50 automotive manufacturers globally.
The company added that it expects to produce more than seven million components for electric drivetrains by 2026 and currently manufactures around seven electric motors per minute worldwide.
