Rumors of a factory diesel engine for the Jeep Wrangler have been circulating since 2008, 2013, and early 2015. They've been available in overseas markets forever but have long been denied to American buyers. It's shame, too, because the 3.0L eco-diesel is a potent powerplant that has already proven itself to meet US emissions standards so it's lack of availability is simply a marketing decision slap in the face of the brand's enthusiast base. In the meantime, owning a "diesel Jeep Wrangler in America" will continue to be limited to a small niche.
