BorgWarner, a global leader in innovative and sustainable mobility solutions, has reached an agreement with Stellantis to supply its 50 mm variable turbine geometry (VTG) turbocharger for the automaker’s all-new Hurricane 4 Turbo 4-cylinder gasoline engine. This engine will debut in the 2026 Jeep® Grand Cherokee (with late availability). Additionally, BorgWarner will provide its electric variable cam timing (eVCT) technology for the Jeep Cherokee, as well as its EP6 four-cylinder engine.

“We are pleased to partner with Stellantis on these exciting project launches,” said Dr Volker Weng, Vice President of BorgWarner Inc and President and General Manager, Turbos and Thermal Technologies. “Our long-standing relationship includes supplying the OEM with several turbos for previous vehicle models, and this specific project marks our shift into the next generation of turbos.”

BorgWarner’s VTG turbocharger technology combines a high-performance turbo with advanced wastegate functionality to enhance both emissions efficiency and engine performance. As the only turbocharger of its kind to combine VTG and wastegate technologies, this system enables quicker catalyst heating during cold starts. The VTG provides precise boost control, optimizing engine performance across a wide range of speeds. Additionally, the technology supports a high Miller cycle, offering improved fuel economy and reduced compression at lower speeds, while increasing boost at higher speeds for greater power output.

The integration of BorgWarner’s eVCT technology into the Jeep Cherokee’s EP6 engine marks the first use of this system on a Stellantis engine. This application is expected to deliver significant improvements in fuel economy, performance, and emissions reduction. Unlike traditional systems, eVCT offers a broader phasing range and operates independently of oil pressure, enabling advanced combustion strategies that enhance efficiency and lower emissions.
