It’s hard to improve on an icon; people simply expect too much. Yet somehow, Jeep has accomplished the impossible with the all-new 2018 Wrangler JL. Every nut and bolt has been improved for better on-road comfort, off-road performance, and even fuel economy. Much of this is credited to the 200-pound weight reduction thanks to aluminum doors, hood, windshield frame, and tailgate. The diet combines with Jeep’s new hybridized 2.0-liter Hurricane turbo-four and an eight-speed automatic for the best fuel economy ever in a Wrangler. Even the familiar 3.6-liter Pentastar V-6 returns with fuel-sipping improvements. But those chasing the ultimate fuel efficiency will love the 3.0-liter EcoDiesel V-6 coming in 2019.
