It’s been a long time coming, but the 2018 Jeep Wrangler JL is finally here. It debuted in all of its two-door and four-door glory, sporting three different engines, two transmissions (including a new eight-speed auto,) fresh interior design with a new Uconnect infotainment system, body-on-frame design, and more than 75 available safety and security offerings. There’s already a host of performance parts from Mopar available and, with four different trims available (three for the two-door plus the Sahara trim on four-door models) there’s definitely an option for anyone with a hankering for a new off-road but road-capable machine.
According to Jeep, all models include a trail-rated badge due to the outstanding four-wheel drive system that includes a 2.72:1 crawl ratio on Sport and Sahara models, a 4LO ratio of 4:1 and locking differentials on Rubicon models, and the ability to ford up to 30-inches of water when properly equipped. Furthermore, the new JL Wrangler can haul as much as 3,500 pounds and can be had with 17-inch off-road wheels. Rubicon models get 33-inch tires as standard equipment while all models get a standard approach angle of 44 degrees, breakover angle of 27.8 degrees, departure angle of 37 degrees, and a minimum ground clearance of 10.9 inches.
When equipped with the 3.6-liter Pentastar, the Wrangler will offer 285 horsepower and 260 pound-feet of torque. The new 2.0-liter, hybridized, four-cylinder offers as much as 270 horsepower and 295 pound-feet of torque, and – for those of you who really want some serious torque – the new 3.0-liter EcoDiesel V-6 will deliver 260 horsepower and an astonishing 442 pound-feet of torque on demand. That new eight-speed auto offers up decent economy and simple stop-and-go driving and can be equipped on any model. Real Jeep fanatics will surely go for the three-pedal-and-six-gears standard offering with a revised shift pattern, shorter throws, and a 4.41 ratio for better efficiency, higher speeds, and quick acceleration. All told it’s not bad, but we’ll let you decide for yourself once we update our full review. Until then, you can check out the debut video below, and check out the important specs below along with the full press release at the bottom.
