2018 Jeep Wrangler Unlimited JL with 3.6L V-6 Gets Official Fuel Economy Ratings

Base Engine Gets Up to 23 MPG

Nov 3, 2017
The new 2018 Jeep Wrangler Unlimited JL underwent EPA testing recently, and today, those fuel efficiency numbers hit the web.
As stated on fueleconomy.gov, the “2018 Jeep New Wrangler Unlimited 4WD” will achieve 18 city/23 highway/20 combined mpg when kitted with the 3.6L V-6 and eight-speed automatic transmission. When equipped with the standard six-speed manual, the city and combined numbers drop one tick.
Compared to the 2018 Jeep Wrangler Unlimited JK (which will be produced simultaneously for the first few months of the JL’s lifecycle), the JL represents a moderate efficiency increase. Compared to the outgoing model and its five-speed automatic transmission, the JL auto gets 2 city mpg and 3 highway mpg better, for a 2-mpg combined improvement. The JL manual’s 17 city/23 highway/19 combined mpg are better than the outgoing JK manual’s 16/21/18 figures.

It’s not clear what measures Jeep took to improve the JL’s fuel economy, as the 3.6L Pentastar engine is largely carryover from the outgoing Wrangler. Weight loss surely helped, as the new off-roader will feature extensive use of aluminum on the body panels, and the JL’s aerodynamics have been improved from “brick” to “slightly slanted brick.” Furthermore, the new-to-Wrangler automatic transmission, which is a ZF unit used in other Fiat Chrysler products, likely pulled some weight in helping fuel economy.

We got our first official look at images of the all-new Wrangler on Wednesday at a SEMA preview, and its improved efficiency only stands to make us more excited for the latest iteration of Jeep’s most iconic nameplate. We’ll see the JL in full in three weeks when it’s revealed at the 2017 Los Angeles Auto Show.
