The Grand Cherokee will have two rows of seats at first. I'd expect a stretched chassis with three rows (Grand Cherokee XL perhaps) in 2012.
Darton is right about the improved 3.6L gas V6. It's got 280 hp and 260 ft-lbs., up from 202 hp and 237 ft lb in the 2009 V6. An 11% improvement in fuel mileage would put it at 19 mpg combined. This engine will find its way into the Wrangler at some point.
I think I remember that the '11 is built on the same platform as the Mercedes G class? It would make sense.
Trail Rated, indeed.
