BorgWarner to Supply VTG Turbochargers for HEVs

BorgWarner Inc. has secured a contract with a major European original equipment manufacturer (OEM) to supply its variable turbine geometry (VTG) turbocharger for a hybrid electric vehicle (HEV) platform. The agreement positions the company within the OEM’s global supply chain and will support one of its first HEV offerings in North America. Start of production is scheduled for 2028.

The VTG turbocharger is engineered to deliver precise engine control across a wide speed range, enhancing performance, fuel efficiency and emissions management. Electrically actuated adjustable vanes regulate pressure upstream of the turbine, enabling near-instant acceleration and improved transient response. The system has been customised to meet specific size and packaging requirements, featuring an updated turbine housing to suit space constraints while maintaining performance standards.

The turbocharger also incorporates a shot-peened compressor wheel to enhance strength and durability. The shot-peening process improves resistance to wear, supporting longer component life under sustained operating conditions. Additionally, an integrated silencer at the compressor outlet helps reduce in-vehicle noise levels.

With established experience in supplying VTG solutions for similar applications in Europe, the company continues to expand its presence in electrified mobility platforms, reinforcing its role in the transition towards more efficient hybrid powertrains.
