The Grand Cherokee plug-in hybrid is badged as a 4xe. It can cover about 25 miles of electric driving range before transitioning into a hybrid operation. The 2.0-liter turbo four-cylinder that comes with the 4xe has some punch and it feels refined. It takes about two and a half hours to charge the battery. Fuel economy as a hybrid is estimated to be 23 mpg combined by the EPA. We measured 21 mpg overall with the standard 3.6-liter V6. Like the regular Grand Cherokee, handling is sound and secure, brake pedal feel is firm and inspires confidence, and the ride is firm yet absorbent, particularly with the smaller 18-inch tires. Off-road seekers will want the Trailhawk version with its off-road modes and height adjustable suspension. The latest Uconnect 5 infotainment system has many features and levels of customization but requires an initial learning curve. AEB with pedestrian and cyclist detection, AEB highway, BSW, and RCTW are standard.
