If this has already been posted, sorry. If not the 2014 GC will be getting as an option a 3.0L V6 Diesel engine. They are calling it the EcoDiesel. It's rated at 240 HP and 420lb-ft of torque, hooked up to an 8 speed AT. It makes more torque than the 5.7L hemi. Advertised mpg is 30. I'm guessing the sticker price for the diesel engine is going to be close to $4,000 more than the 3.6L Pentastar GC will be. It should be interesting to see how successful the engine is here in the US, and if the 2014 Wrangler will be offered the same way.
