2018 Jeep Wrangler to offer optional 368-hp 4-cylinder engine

The redesigned 2018 Jeep Wrangler will feature an optional turbocharged 2.0-liter inline-four engine that produces 368 hp, according to documents Fiat Chrysler filed with the National Highway Traffic Safety Administration.

Thetruthaboutcars.com broke the story, which was picked up by posters on  Wrangler-centric website jlwranglerforums.com. The Wrangler forum site posted the document, a vehicle identification number decoder. While a new inline-four variant is listed, the VIN decoder does not identify a diesel-powered Wrangler, which could come later or may have been postponed because of FCA's ongoing issues with regulators over its diesel emissions.

The next-generation Wrangler, dubbed JL, will begin production within the next several weeks but isn't expected to show up at dealerships until after the new year. The document indicates that the redesigned Wrangler will come standard with its current 285-hp 3.6-liter V-6. Both engines will be mated to a new-to-the-Wrangler eight-speed automatic transmission to improve fuel economy.
