The old 3.8-litre V6 makes way for the versatile Pentastar engine, which sends a healthier 285 horsepower and 260 lb-ft of torque to all four wheels through a 5-speed automatic transmission or 6-speed manual (the first manual gearbox to be available with this powerplant).
Jeep claims the transplant will improve fuel economy on the road while preserving all the Wrangler's capabilities off the road. Moreover, accelerations from 0 to 96 km/h will be 25-percent faster at 8.4 seconds.
Following the lead of many Chrysler products, the interior will feature higher-quality materials, automatic temperature controls and larger rear windows for greater visibility.
Elsewhere, classic design cues such as the 7-slot grille, round headlights, exposed door hinges, half-doors, fold-down windshield and removable top are back.
The Jeep Wrangler and Wrangler Unlimited will continue to be available in four trim levels, including Sport, Sport S, Sahara and Rubicon.
