Hurricane 4: Jeep’s 2.0L Turbo Engine That Breaks Four-Cylinder Boundaries
Jeep's Hurricane 4 is a 2.0L turbo making 325 hp that uses a Formula 1–derived Turbulent Jet Ignition pre-chamber with twin sparks, plus direct/port injection, a variable-geometry turbo, electric cam phasing and Miller cycle to maximize power and efficiency—nearly 27 mpg highway in the Grand Cherokee—marking one of the most tech-packed four-cylinders in modern cars.
