Bosch has secured a large-volume electric motor supply order from Mercedes-Benz running into the 2030s, with the components destined for the German automaker’s next generation of electric powertrains. The supplier announced the order from its Stuttgart headquarters, framing it as an extension of an established commercial relationship. The deal covers motors across several performance classes and lands as Bosch continues to scale a global electric-drive business that the company says now serves more than 50 automakers worldwide. Further detail is available in the Bosch press portal.
Highlights
- Bosch will supply electric motors across multiple performance classes to Mercedes-Benz for its next generation of electric powertrains, with the partnership extending into the 2030s
- The supplier added more than 70 customer projects worldwide in 2025 and currently provides electromobility technology to more than 50 automakers
- Bosch plans to manufacture more than seven million electric-driving components in 2026, with roughly seven electric motors leaving its production lines every minute
- The company’s motor platform delivers up to 98 percent efficiency, uses rotor oil cooling, and offers scalable length to fit different axle configurations
A Long-Standing Partnership Extended
The new agreement builds on an existing commercial relationship between the two German companies. Markus Heyn, member of the Bosch board of management and chairman of Bosch Mobility, said the order “reaffirms our long-standing partnership with Mercedes-Benz and shows that we can successfully contribute our expertise to technologically demanding projects as well.”
The contract follows a year in which Bosch booked more than 70 electromobility customer projects globally. Mercedes-Benz has been deepening its electric portfolio through models such as the electric CLA, named European Car of the Year 2026, and the recently unveiled electric GLB with 800-volt architecture.
Motor Specifications and Platform Architecture
Bosch’s current-generation electric motors are built on a scalable platform designed for integration flexibility across vehicle programs. Key technical features include:
- Efficiency: Up to 98 percent, driven in part by new winding technology
- Cooling: Rotor oil cooling for thermal dissipation
- Scalable length: Motor length varies with required power output, enabling installation across different axle variants
- System impact: The combination of efficiency, cooling, winding, and scalability is intended to reduce weight, installation space, and total system cost
The supplier sells the platform as a way for automakers to integrate electric powertrains across multiple vehicle programs without bespoke engineering for each application.
Scale of the Electric-Drive Business
Bosch plans to produce more than seven million electric-driving components in 2026. Output already runs at roughly seven electric motors per minute across the company’s global manufacturing footprint. North American motor production runs at Bosch’s Charleston, South Carolina facility, part of a global network supplying customers regionally.
Beyond Mercedes-Benz, Bosch operates a joint venture with TataAutocomp Systems in India developing and manufacturing e-axles for the Indian market. Marco Zehe, president of Bosch’s Electrified Motion division, said the company “already work[s] with almost all Chinese car manufacturers, as well as with numerous international automakers operating in China,” with more than 30 customers in that market receiving electric-drive solutions.
X-in-1 Integrated Systems
Alongside individual electric motors and complete e-axles, Bosch offers what it calls “X-in-1” solutions — packages that bundle the electric motor, power electronics, transmission, and energy management into integrated systems. The supplier positions these higher-integration packages as more compact and lighter than discrete-component assemblies, with corresponding cost advantages.
The company’s electromobility offering also extends down to component level, including silicon carbide chips for power electronics — covering, in Bosch’s framing, the full spectrum from semiconductor to complete powertrain.
