- Bosch’s new e-motor achieves record efficiency with significantly reduced energy losses and high power output consistency.
- Its modular and supply chain optimized design supports scalable global production across multiple vehicle segments.
Robert Bosch GmbH has introduced an advanced generation of permanent-magnet synchronous electric motors engineered for both battery-electric and hybrid vehicle platforms. The system focuses on maximizing efficiency while maintaining strong real-world performance, offering automakers a viable path to optimize energy usage and reduce overall system costs. Developed with scalability in mind, the new motor architecture is suitable for a wide range of vehicle categories, supporting both passenger and commercial mobility requirements across global markets.
Record Efficiency and Reduced Energy Losses
The newly developed e-motor achieves a world-leading efficiency level, with energy losses measured at just 0.85 kWh per 100 km under the WLTC cycle. This represents a reduction of up to 30% compared to conventional systems, significantly improving energy utilization within electric and hybrid powertrains. The motor also delivers a continuous-to-peak power ratio of up to 93%, ensuring consistent performance across varying driving conditions. This balance between efficiency and output allows manufacturers to reduce battery size while maintaining driving range and performance expectations.
Modular Architecture for Multi-Segment Applications
The e-motor is built on a modular platform that enables flexible integration across different vehicle segments, from compact passenger vehicles to larger commercial applications. This modularity allows OEMs to standardize components while adapting to varying performance and packaging requirements. By offering a scalable solution, Bosch enables manufacturers to streamline development processes and accelerate deployment timelines, supporting both electrification strategies and hybrid system integration.
Supply Chain Optimization and Sustainability Focus
The system incorporates sourcing strategies designed to enhance supply chain resilience and sustainability. This includes the use of rare-earth-reduced magnet configurations, addressing material dependency concerns while aligning with environmental targets. Additionally, localized production strategies support compliance with regional regulations and reduce logistical risks. These measures help automakers operating in Germany and other global markets manage supply uncertainties while meeting evolving regulatory and sustainability requirements.
Series-Ready Solution for Global Deployment
Bosch positions this new e-motor as a production-ready solution capable of supporting large-scale global programs. Its combination of high efficiency, modular design, and supply chain adaptability makes it suitable for widespread adoption across multiple vehicle platforms. As automakers continue to transition toward electrified mobility, this system provides a practical approach to balancing performance, cost efficiency, and sustainability goals without compromising technical reliability.
