BorgWarner to power Stellantis’ next-gen Jeep engines with turbo and eVCT technologies

Press Release

BorgWarner has announced a new supply agreement with Stellantis to provide its 50 mm Variable Turbine Geometry (VTG) turbocharger for the automaker’s upcoming Hurricane 4 Turbo engine, set to debut on the 2026 Jeep® Grand Cherokee. The collaboration will also introduce BorgWarner’s Electric Variable Cam Timing (eVCT) system on Stellantis’ Jeep Cherokee featuring the EP6 four-cylinder engine, marking the first-ever use of eVCT on a Stellantis powertrain.

The VTG turbocharger is designed to deliver both performance and efficiency, combining variable geometry and wastegate functionality — a first-of-its-kind integration. This dual setup improves engine responsiveness and reduces emissions by allowing faster catalyst heating during cold starts and providing precise boost control across all driving conditions. Supporting a high Miller cycle, the system enhances low-speed fuel efficiency while increasing boost and power output at higher speeds — ensuring optimal performance without compromising economy.

Meanwhile, BorgWarner’s eVCT technology operates independently of oil pressure, offering a broader phasing range that enables advanced combustion strategies. This leads to improved fuel economy, reduced CO₂ emissions, and enhanced engine flexibility. According to Dr. Volker Weng, Vice President of BorgWarner and President of Turbos and Thermal Technologies, this project marks “the next generation of turbo innovation,” extending the company’s long-standing partnership with Stellantis.

By combining its expertise in thermal, turbo, and electric propulsion technologies, BorgWarner continues to position itself as a key enabler in Stellantis’ journey toward sustainable and high-efficiency mobility solutions across its future Jeep lineup.
