GMC Yukon Hybrid – 2008 Preview: Though attitudes are changing, talk of hybrids leads many folks to think of compact and midsize cars like the Honda Civic Hybrid and Toyota Prius, with more and more becoming aware of regular sedans and SUVs such as the Lexus GS 450h and Saturn Vue Green Line. What they don’t envision are large SUVs, though that will start to change when the 2008 GMC Yukon Hybrid (and 2008 Chevrolet Tahoe Hybrid) arrives later next year. Engineers have blended the utility of a full-size rig, the power and capability of a V8 engine, and an expected 25-percent gain in fuel economy via the use of a dual-motor, two-mode hybrid system.
