The Wrangler and its 4-door sibling, the Wrangler Unlimited, come in four trim levels for 2014, all with a 3.6L V6 engine. The engine makes 285 hp at 5200 rpm and 260 lb-ft of torque. All Wrangler models have a 6-speed manual transmission as standard equipment, while a 5-speed automatic is optional. All Wrangler models also come with electronic stability control, a full-size spare tire and shift-on-the-fly 4-wheel drive; the Sahara and Rubicon models add traction control. All models also share new Dana solid front axles and heavy-duty rear axles, ensuring that the Wrangler will keep moving over obstacles that would stop other off-roaders. Every 2014 Wrangler's interior features cloth-wrapped bucket seats with driver height-adjustment, a tilt-adjustable steering wheel, temperature and compass gauge, cruise control and an anti-theft engine immobilizer. The Sahara trim receives heated power mirrors, power windows and remote keyless entry. The suspension is a heavy-duty type and the wheels are 18-inch aluminum. A standard 3-piece hard top is also included that comes with a rear wiper, defroster and tinted windows. The Sahara Wrangler gets performance suspension, 18-inch aluminum wheels, fender flares, a leather steering wheel, side steps, satellite radio with a one year subscription and remote keyless entry. The Rubicon is the Wrangler's factory off-road model. Mechanically, the Rubicon is fitted with Tru-Lok front and rear axles, Dana heavy-duty axles, an electronic sway bar disconnect and 4:1 Rock-Trac 4-wheel drive system. Inside and out, the Rubicon is fairly subdued, and the interior is intended to be more functional than luxurious, with cloth seat trim and a basic AM/FM/CD stereo. The options list however, is broad enough to configure Wranglers any way the buyer wants, ranging from a 30GB media center stereo that includes a 6.5-inch touch screen, navigation and a USB port, Katzkin 2-tone leather seats, remote start and a trailering upgrade package.
