New Delhi: BorgWarner has been awarded a new eTurbo™ program with a major European OEM for an advanced hybrid passenger car application, further strengthening BorgWarner’s leading position in electrified boosting technologies. Production is scheduled to begin in 2029.
“This new award underlines the strength of our eTurbo™ technology and the trust our customers place in BorgWarner’s electrified boosting solutions,” said Dr. Volker Weng, President and General Manager, BorgWarner Turbos and Thermal Technologies. “By continuing to evolve our proven 400-volt eTurbo™ platform, we are helping our customers meet some of the industry’s most demanding requirements for performance, efficiency and emissions compliance.”
The BorgWarner eTurbo™ is an electrically assisted turbocharger that integrates a high-speed electric motor directly on the turbo shaft to actively drive the compressor. The system eliminates turbo lag, enables significantly faster boost pressure build-up, and delivers 20 kW of continuous electrical power and up to 30 kW peak for both performance enhancement and energy recuperation. Excess exhaust energy is converted into electrical energy and fed back into the vehicle’s high-voltage system rather than being lost through a conventional wastegate.
The new program is based on a continuous evolution of BorgWarner’s proven eTurbo™ platform currently in series production. A key new feature is the introduction of remote power electronics, which allow flexible positioning within the vehicle and engine compartment, supporting integration into the most challenging packaging environments. Designed for operating speeds of up to 145,000 rpm and exhaust gas temperatures above 1,000°C, the system combines advanced cooling strategies with high-performance silicon carbide based power electronics to ensure efficiency, durability and reliability under the most demanding operating conditions.
Beyond performance, the eTurbo™ plays an important role in helping automakers meet upcoming emissions regulations such as Euro 7 (EU7), Super Ultra-Low Emission Vehicle (SULEV), and China National 6b Emissions Standards (C6b) by eliminating fuel enrichment at high load, reducing exhaust backpressure and converting otherwise lost exhaust energy into usable electrical power. With proven series production and extensive field experience, BorgWarner remains the only supplier offering a 400-volt eTurbo™ in series.
