Jeep Wrangler delivers unmatched off-road capability with legendary four-wheel drive and is produced with more than seven decades of 4x4 engineering experience behind it. Wrangler continues to offer a body-on-frame design, front and rear five-link suspension system, live axles and electronic lockers.

Jeep Wrangler now offers a choice of two transmissions: a six-speed manual and a five-speed automatic gearbox.

Along with a new powertrain, Jeep engineers have thoroughly optimized ride and sound characteristics of the Jeep Wrangler's body-on-frame design. New motor and transmission adaptations and revised suspension calibrations contribute to overall improvements that are immediately evident both on- and off-road.

The interior sound quality is greatly improved through refinements in the powertrain mounting system, noise damping in the firewall and the inclusion of the first Jeep Wrangler engine cover to effectively isolate the cabin from noises emulating from the engine and road surfaces.

On the outside, engine noise is barely perceptible at idle. With the new 3.6-liter V-6 engine, all accessories are mounted directly to the engine with no accessory brackets. This helps ensure that all accessories, including the power steering pump, alternator and air conditioning compressor, are anchored firmly and less susceptible to vibration and noise.

Shocks have also been retuned and are designed for optimum balance between advanced on-road handling and rugged off-road capability.
