The Wrangler has been diesel powered for nearly a decade, for export only.Saw (and heard) a Diesel JK here in Germany today. Pretty cool. Hope it makes i to the U.S. market.
Hopefully the VM 3.0 which is EPA compliant in the Grand Cherokee, makes its way into the Wrangler.
The Wrangler now uses the VM 2.8 which is not EPA compliant.
