Customization is the highlight of the 2018 Jeep Wrangler Unlimited. The three trim levels and available packages add to the fun. All three begin with a 285-horsepower, 3.6-liter V6 engine with a six-speed manual transmission and four-wheel drive. The Sport edition carries the standard features including an eight-speaker sound system, USB port, heated side mirrors, compass, cloth upholstery, split-fold rear bench, 16-inch steel wheels, cruise control, steering-wheel-mounted audio controls, and all-terrain tires. The Sahara kicks it up a notch with a leather steering wheel, SiriusXM AM/FM/HD/Satellite radio with a 12-month subscription, auto-locking doors, heated front seats, a premium sound system, MOPAR leather upholstery, and a three-piece hardtop. The Rubicon adds front-rear locking differential, automatic climate control, power windows, a trip computer, body-colored fender flares, a premium soft top, and 17-inch painted alloy wheels. All have their unique branding that matches the vibe of the model.
