Sorry, its just Internet speculation. I wish there was something more concrete. But speculation, rumor or whatever you want to call it, the diesel line up for Jeep is important- because in the next 3 years (and again in 2011) CAFE standards are going to rise, this time CAFE will include trucks and SUV's. Jeep is in a poor position because 95% of their vehicles are SUV's/trucks so they will be forced (its about time) to increase their MPG over their entire fleet, because ultimately Jeep is pulling down the numbers for DC. So its the diesel that will save them - at least in the next 3-5 years. Of course they could be developing some new, super, hybrid engine, but again, anything like that wont see the light of day for the next couple of years - and will be expensive - so rule out use in a Wrangler. I really cant see jeep going in any other direction. At least for now.
