The 2018 Jeep Wrangler EcoDiesel has been spied testing once again, providing us with more evidence that the next-generation off-roader will be offered with the venerable oil-burning engine.
According to JL Wrangler Forums, this mule was given away as a diesel tester due to the presence of a DEF tank on the underbody, though there doesn’t appear to be any photos of that. We’re assured it was present, though, and that it was covered up with its own skid-plate so it doesn’t get damaged when off-roading.
From the looks of things, this mule is based entirely on the JK Jeep Wrangler. Even though the next-generation JL Wrangler will look a bit different, they are likely testing the diesel engine in the current version of the Jeep for cooling and packaging purposes.
The EcoDiesel V6 in the Wrangler should be mated to Fiat Chrysler’s ZF-sourced 8HP75 eight-speed automatic transmission when it arrives. A six-speed manual is expected to return with the new Wrangler, though it seems unlikely it would be offered in the diesel.
