2009 GMC Yukon Hybrid

About 2009 GMC Yukon The GMC Yukon Hybrid delivers a dramatic improvement in fuel economy over non-hybrid models -- up to a 50-percent improved mileage in city driving -- with all of the comfort and capability customers expect in a full-size SUV. The Yukon Hybrid's vastly improved fuel economy over gasoline-only siblings is due largely to a state-of-the-art hybrid system using GM's all-new Electrically Variable Transmission. Along with Active Fuel Management, the Yukon Hybrid uses specific aerodynamic aids and reduced-mass components to help achieve EPA ratings of 21 mpg in the city and 22 on the highway for 2WD models. That compares with ratings of 14 mpg in the city and 20 mpg on the highway for the smaller-displacement, less-powerful 5.3L base engine. With 4WD models, the fuel savings are rated at 20 mpg in both city and highway driving. The 5.3L base models are rated at 14 in the city and 19 on the highway. The superior passenger comfort of the Yukon Hybrid has been maintained throughout, with a quiet cabin environment at the very top of the list. Yukon Hybrid models match their gasoline-only siblings in comfort and convenience, but attention to acoustic details makes these SUVs even more enjoyable.
