Farmington Hills, Mich.— Bosch has introduced a new generation of permanent-magnet synchronous e-motors designed to set the benchmark for series-ready electric propulsion. The advanced motor delivers a world-record gain in efficiency, with only 0.85 kWh/100 km losses in the WLTC cycle and effectively cutting the losses by up to 30 percent. Depending on use case, the motor provides a continuous-to-peak power ratio of up to 93 percent, combining breakthrough efficiency with robust, real-world performance.
WLTC, or Worldwide Harmonized Light Vehicles Test Cycle, is a globally recognized test that measures how efficiently a vehicle uses energy under realistic driving conditions so automakers and consumers can compare performance across different vehicles.
By maximizing energy efficiency and power density, the technology supports the industry’s transition to scalable, high-performance electric mobility.
“Efficiency is the new horsepower,” said Kevin OKeefe, regional president of Electrified Motion, Bosch in North America. “This next-generation e-motor demonstrates how Bosch is helping our customers unlock greater performance, lower costs and enhanced supply-chain resilience. By enabling smaller batteries without compromising range, we’re delivering real value to automakers and drivers alike.”
Engineered for broad applicability, the motor is designed for both battery-electric and hybrid powertrains. Its modular architecture supports a wide range of vehicle segments, from passenger cars to commercial applications, allowing manufacturers to streamline development and accelerate time to market.
The new e-motor also reflects Bosch’s focus on global flexibility and long-term resilience. It incorporates sourcing strategies that support diversified supply chains, including rare-earth-reduced magnet configurations and, where available, localized production. This approach supports automakers in addressing regulatory requirements, mitigating supply risks and aligning with evolving sustainability and supply chain considerations.
With experience of 8 million electric motors of all generations produced so far and decades of experience in electrification and large-scale manufacturing, Bosch is positioning the new motor as a series-ready solution capable of supporting global production programs. The company continues to invest in innovations that advance efficiency, scalability and sustainability across the electric mobility ecosystem.
