While the JL Wrangler has been on the market for awhile now, the much-anticipated diesel variant has yet to arrive. Finally, the Wrangler EcoDiesel is nearing launch and its pricing has leaked out, showing that the oil-burner option is going to cost a hefty sum.

The folks over at JL Wrangler Forums have consistently been at the forefront when it comes to leaking JL Wrangler details, so it comes as no surprise they’ve uncovered the diesel pricing first. According to their information the 3.0-liter diesel V-6 will be a $4,000 option on the Wrangler. On the surface this sounds good, since the same engine is a $4,995 option on the Ram 1500, but the premium doesn’t stop there for Wrangler diesel buyers.

Checking the EcoDiesel option box automatically requires buyers to add the eight-speed automatic transmission, which is an additional $2,000 option. All in, there’s about $3,250 separating the diesel and the 3.5-liter Pentastar V-6 with the automatic.

Not every detail surrounding the Wrangler diesel is known yet. EPA ratings have yet to be announced, though it is rumored to offer greater than 30 mpg highway. Given the Ram EcoDiesel can manage similar figures, it shouldn’t be difficult for Wrangler to get similar ratings.

Production of the Wrangler diesel will commence on November 25th, but the order books are open now for interested buyers.
