BorgWarner is first-to-market with its electric Torque Vectoring and Disconnect (eTVD) system for battery electric vehicles (BEVs) with launches for Polestar and an additional major European OEM.

The eTVD is part of the company’s electric torque management system (eTMS) portfolio. It is designed to control wheel torque intelligently to increase stability, provide superior dynamic performance, and improve traction during launch and acceleration.

The eTVD is currently in production on the Polestar 3 SUV, with production for the European OEM to follow later this year.
    
“Our new EV torque management systems showcase our multi-disciplinary expertise, system integration capabilities and the exceptional work of our BorgWarner team,” said Volker Weng, vice-president of BorgWarner, and president and general manager of BorgWarner Drivetrain Systems.

“With the market transitioning to more software-defined modules and vehicles, it is critical to have sophisticated systems in place, like our eTVD that can precisely and quickly calculate, predict and control vehicle behaviour across a wide range of situations. We have received exceptionally positive feedback from customers regarding their test-drive experiences, and we look forward to addressing further market needs with our software, controls and calibration expertise.”
        
The high-performing eTVD offers a 3-in-1 system, replacing the differential, and featuring both torque vectoring and an on-demand disconnect function. In contrast to brake-based systems, torque vectoring prevents unnecessary brake interventions, therefore reducing harshness and vibration. This leads to less wear and tear on brakes and tyres, with the added benefit of lower particle emissions.
        
BorgWarner’s eTVD systems offer high-level software and controls that can be customised by OEMs to align with their own platform needs and specific brand characteristics.
        
The higher weight of BEVs can reduce their agility, but BorgWarner’s eTVD systems enable a much lighter feel of the vehicle while increasing overall safety. A smart design and intuitive software minimise the risk of undesired driving characteristics, and also enable superior traction regardless of road and weather conditions. Torque response is instantaneous in challenging and demanding scenarios, ensuring smooth, safe rides.
