This is what you call, "thinking ahead", of course this is a little late, but better late than never. The whole automotive landscape here in the U.S will change forever compared to what we know it as now. Trucks and SUV's will become smaller and lighter and built using unit-body construction as oppose to prelethic body on frame construction. I think the Denali XT is a perfect and smart example of the future of the truck; they can manipulate various aspects of the dimensions but you'll still have a utility vehicle in a more efficent and practical package that will cater to those wanting something bigger with the ability to haul stuff to an fro, and relastically how many people actually NEED 4WD???? Not many.... nor do many need the size of today's SUV/Truck. Some people think because they've got a kid or two on the way they need an SUV with three rows of seats that could accomadate multiple twin sets.... ridculous!

As far as performance cars go; there will always be demand. Not everyone wants a mundane means of personal transportation, because a car is exactly that, "personal transportation". Peope want something that expresses thier individuality and performance cars give them that option among a variety of other unique and specialized products. As Dragon said, cars are more adpatable to more stringent fuel economy standards than trucks/SUV's because their size and weight are more managable and easily modified than the ladder. Hopefully many people will still want to buy muscle cars even though going forward they won't be the same today as they were several years ago. Times change, and I know that both the domestics and we that buy them will adapt, sucessfully.
