According to the EPA, the current Wrangler Unlimited with the 3.6-liter V6 and six-speed manual clocks 16 miles per gallon in the city, 21 on the highway, and 18 combined. The 2018 version with the same six-speed manual comes in at 17/23/19. Switching transmissions, the current model with the five-speed automatic hooks up 16/20/18, the 2018 model with an eight-speed automatic does 18/23/20.
Those numbers might not jump off the page, yet according to the EPA's cost calculator, you'll save $250 per year on gas with the eight-speed auto 2018 Wrangler Unlimited, $150 per year with the coming six-speed manual. The eight-speed auto option also exceeds Chrysler's prediction from 2014 of a nine-percent improvement in fuel economy over the five-speed auto. Now we wait for numbers on the dark horse four-cylinder, which we'd expect to best the sixer's numbers, unless the rumors are true and the four-pot really is packing every wild horse it can handle. In that case, we'll turn to the EcoDiesel for frugal kicks. If we don't find out beforehand, we can expect those goodies and more at the LA Auto Show in December.
