Jeep Unveils 2026 Hurricane 4 Turbo Engine: 325 HP with Cutting-Edge Tech

Jeep has unveiled its all-new 2.0L turbocharged inline-four "Hurricane 4" engine, delivering a maximum output of 325 horsepower and establishing itself as one of the most powerful production four-cylinder engines in the world. The engine incorporates Formula 1-derived Turbulent Jet Ignition (TJI) technology, featuring a pre-chamber ignition system, dual spark plugs, and a combined direct and port fuel injection setup—dramatically enhancing combustion efficiency. Coupled with a variable geometry turbocharger (VGT), an electric cam phaser, and Miller cycle operation, the engine achieves an impressive 27 mpg on the highway while also improving cold-start emissions and low-end responsiveness. Despite powering large SUVs like the Grand Cherokee, the engine delivers surprisingly strong performance, with minimal turbo lag and robust mid-to-high-range power delivery. By bringing numerous high-performance technologies down to its base powertrain, Jeep has created what is arguably the most groundbreaking internal combustion engine in the brand’s history.
