GMC doesn't do concepts very often but their latest example was unveiled here at the Chicago Auto Show. The new Denali XT concept is primarily a styling exercise but it also highlights a lot of ideas for the future of the truck market. As new fuel economy regulations kick in the coming years, trucks will have to get smaller and lighter and a car based truck like this will likely become a viable option for drivers who chose pickups for personal use rather than as a work truck. Regardless of whether this particular vehicle turns up, the powertrain almost certainly will. Future GM trucks will very likely use a smaller displacement V-8 like this 4.9L (or even smaller) with direct fuel injection. It many applications it will also be combined with the two-mode hybrid system as volumes increase and cost is reduced.
