Specifications leaked online for the redesigned Jeep Wrangler confirm that the off-roader will someday feature a 3.0-liter diesel variant and that efforts to put the vehicle on a diet proved difficult.
The 2018 JL Wrangler enters production next month and will be in showrooms early next year.
The internal FCA document, which appeared on jlwranglerforums.com, references the two-door version, the four-door Wrangler Unlimited and the upcoming JT Scrambler pickup. According to the document, the diesel variant will be available only in the four-door model and the Scrambler.
FCA had filed notices with federal regulators citing only a standard 3.6-liter V-6 and optional 2.0-liter inline-four engine variants for the JL Wrangler. The notices were filed amid a conflict with the EPA involving 3.0-liter EcoDiesel emissions in the Ram 1500 pickup and Jeep Grand Cherokee.
The new documents show the next-generation Wranglers with a maximum towing capacity of 3,500 pounds and maximum payloads of between 1,040 and 1,310 pounds, depending on configuration. That indicates that designers have trimmed between 50 and 150 pounds, depending on the model, from the current JK Wrangler.
FCA executives had rejected using weight-saving aluminum body panels on the Wrangler, which would have resulted in greater weight reduction. The JL will use aluminum for its doors and hood.
The documents show the Scrambler pickup will carry a tow rating of 6,500 pounds, with a maximum payload of 1,400 pounds in all but the premium trimmed versions, which will have a 1,100-pound maximum payload.
