If there's one single item we think the Jeep Wrangler sorely needs, it's a new powertrain. The current 3.8-liter V6 engine and four-speed automatic transmission are extremely long in the tooth and feel downright anemic when traveling down paved roads. It could be argued that a small-displacement diesel engine would be the ideal way to add some much-needed grunt and improved fuel efficiency to the iconic off-roader, but apparently that's not going to happen – at least not here in the United States.
Says Michael Manley, president and chief executive officer of the Jeep brand, "We have no plans at the moment for diesel Jeeps in North America, although one of the things I've learned in this business is to never say never... I wouldn't rule it out."
Fortunately, that doesn't mean the 70-year-old Civilian Jeep won't get any updates at all. According to the Toledo Blade – the Jeep brand's hometown newspaper – Chrysler is likely to install its new Pentastar V6 engine, which we'd hope would also include a new six-speed automatic transmission, in the Wrangler starting next summer. Also, we're told that more special edition models will join the recently unveiled Islander and Mountain models. Thanks for the tip, Tom!
