The GMC Graphyte concept vehicle is a refined SUV with all the capability expected in a four-wheel-drive truck, but with 25 percent improved fuel economy enabled by GM's latest two-model full hybrid propulsion system. A tailored design, including an elegant, metal-framed grille gives the Graphyte an urban flair. It was designed and built at the GM Advanced Studio in Coventry , England .

The midsize Graphyte uses a two-mode full hybrid combined with a Vortec 5300 V-8 with Displacement on Demand (DoD) technology. It is similar to the hybrid system that will be available on GMC Yukon and Chevy Tahoe full-size SUVs in 2007.

Two-mode full hybrid technology is at the center of GM's three-prong advanced propulsion strategy that aims to take automobiles out of the energy and environmental debate. Its universal design allows engineers to scale the architecture to fit vehicles of any size. The system fits within the space of a conventional automatic transmission, with a battery pack providing the electric power.
