Bosch has secured a significant long-term agreement with Mercedes-Benz to supply electric motors for the automaker’s next-generation electric powertrains well into the 2030s. The deal marks another important step in Bosch’s expanding role in the global electrification market as demand for advanced EV technologies continues to grow.
The new contract strengthens the long-standing partnership between the two companies and highlights Bosch’s position as a key supplier of high-performance electric mobility systems. According to Bosch, the company won more than 70 electromobility-related customer projects worldwide in 2025 and now supplies over 50 automakers with EV technologies and solutions.
Bosch says its latest electric motors deliver efficiency levels of up to 98 percent while also achieving higher power density through advanced winding technology. The motors also feature innovative rotor oil cooling designed to improve thermal management and maintain consistent performance under demanding conditions.
Another major advantage is the scalable platform architecture. Bosch can adjust the motor length depending on power requirements, allowing automakers to integrate the system across multiple vehicle platforms and axle configurations. This flexible design helps manufacturers reduce development complexity while lowering production and integration costs.
The company notes that combining optimized winding technology, high efficiency, advanced cooling systems, and scalable architecture results in a more compact electric drive unit. The smaller packaging reduces weight and installation space while improving overall system efficiency.
Bosch’s global electromobility business continues to expand rapidly. The company expects to manufacture more than seven million electric-drive components in 2026, with approximately seven electric motors currently rolling off its production lines every minute worldwide.
Beyond its partnership with Mercedes-Benz, Bosch works with a wide range of automakers across Europe, China, and India. In India, the company has partnered with Tata AutoComp Systems to develop and manufacture e-axles for the local market.
China also remains a major focus for Bosch’s electrification strategy. The company says it collaborates with nearly all major Chinese car manufacturers as well as international automakers operating in the country. Bosch has been producing EV-related technologies in China for more than a decade and currently supplies electric driving solutions to over 30 customers there.
Bosch’s electromobility portfolio now spans everything from silicon carbide chips to complete integrated powertrain systems. Alongside standalone e-axles, the company is increasingly focused on highly integrated “X-in-1” solutions that combine components such as the electric motor, transmission, power electronics, and energy management systems into a single compact package.
These integrated systems are designed to reduce complexity, lower weight, and improve cost efficiency for automakers developing next-generation electric vehicles.
As competition intensifies across the EV sector, Bosch’s latest Mercedes-Benz contract signals continued momentum for the supplier’s electrification business and reinforces its growing influence in the future of electric mobility.
