The 4xe has a 270-hp turbocharged inline-four between a 44-hp motor connected through the accessory belt at the front and a 134-hp motor taking the place of the transmission's torque converter at the back.

The motors draw power from a 14.0-kWh lithium-ion battery stashed under the rear seats. Whether the 4xe is running in Electric mode or as a hybrid, torque is routed to the wheels through an eight-speed automatic transmission and a transfer case that offers rear-wheel drive, all-wheel drive (4WD Auto), and high- or low-range four-wheel drive for the off-road crowd.

375 horsepower, an EPA fuel economy of 49 MPGe with the battery charged, and 21 miles of electric driving before the gas engine kicks on. The 4xe makes the same torque—470 lb-ft—as the V-8-powered Wrangler Rubicon 392, which is rated at just 14 mpg combined.
