GMC Graphyte Hybrid SUV Introduced 2005

The GMC Graphyte concept showed the potential of a hybrid system on an attractive mid-size four-wheel-drive SUV. As in the Opel Astra Diesel Hybrid concept, two electric motors supplement a conventional engine, in this case GM’s 5.3-liter small-block V-8, with cylinder deactivation. Fuel economy reportedly gets better by 25 percent over the same engine running on gas. Despite the hybrid drivetrain, GM assures us there will be no loss of performance or utility—golly, it has 22-inch wheels. The so-called two-mode hybrid system can move the vehicle away from a stop using just the electric motors (first mode), and once under way the gasoline engine kicks in and assists the electric motors. When cruising, the Graphyte will shut off its electric motors until more power is needed in, say, a passing situation (second mode). In 2007, GM promises that a hybrid system similar to the one in the Graphyte will be available in the GMC Yukon and Chevrolet Tahoe full-size SUVs. http://www.caranddriver.com/news/gmc-... S645
