Fiat Chrysler Automobiles CEO Sergio Marchionne may be watching Ford experiment aluminium-bodied pickups from afar, but as far as the 2018 Jeep Wrangler is concerned, the lightweight metal may wind up on the iconic vehicle before the Ram 1500 considers taking the plunge.

Automotive News reports Jeep’s engineers and designers are already at work finalizing design work for the next-gen Wrangler, set to enter production in 2017. Based on recent job postings, the brand as an eye on dropping weight for the vehicle as part of its plan to meet ever-tightening CAFE goals. The current Wrangler holds an average of 17 city/21 highway while weighing anywhere from 3,785 to 4,340 pounds depending on trim, while the new Cherokee 4×4 — based on a lighter foundation — pulls 19 city/25 highway at a weight of 4,044 pounds.

Other key components of the plan on the table include an eight-speed automatic and an expanded lineup of fuel-efficient gasoline and diesel powerplants.
