BorgWarner revealed an integrated drive and generator module optimized for range-extended trucks and large SUVs, a technology many see as the predominant electrified strategy for utility vehicles with the headwinds currently facing the BEV market.

The company already has a contract with what it calls a major American automaker to build the model beginning in 2029 for a series of range-extended vehicles.

The integrated drive module (iDM) combines an induction electric motor and gearbox in one compact unit. A generator module, which can be mounted on the drive module, was developed by BorgWarner’s engineers with “an optimized dual inverter design featuring its next-generation Viper power switch technology,” the company said in a news release. The power-dense module is more cost-effective, the company said.

Stefan Demmerle, vice president of BorgWarner Inc. and president and general manager of BorgWarner PowerDrive Systems, said the system allows for the capabilities of an EV with what he called a no-compromises access to the ICE engine.

The electric motor itself avoids permanent magnets, which helps support a resilient supply chain, but is still torque dense, the company says. BorgWarner said the big engineering challenge was to meet the automaker’s high-performance demands while being compact enough to share space with an internal combustion engine.

The company also announced that it would supply a variable turbine geometry turbocharger for a major European OEM’s hybrid EV platform that will be sold in North America. In a VTG turbo, the pitch of the vanes of the turbocharger can be adjusted to affect airflow, allowing optimized turbocharging across a wide range of RPM. They generally reduce the ubiquitous turbo lag and improve low-end torque. The company said that the end effect is better efficiency and fuel economy and lower emissions.

The VTG turbo unit’s compressor wheel is treated with shot-peening, a process that fires hard spheres at the wheel during forging to increase strength and durability, resulting in longer service life for the component. The unit also features noise-reduction tech.

“BorgWarner is proud to extend our long-lasting, trusted partnership with this OEM by supplying our VTG technology to the company’s HEV platform,” said Dr. Volker Weng, vice president of BorgWarner Inc. and president and general manager, Turbos and Thermal Technologies.
