(autoinsidernews) - General Motors today unveiled the 2008 GMC Yukon Hybrid at the Los Angeles Auto Show. Essentially the same vehicle as the Chevrolet Tahoe Hybrid, the GMC Yukon Hybrid, features the world's first two-mode hybrid propulsion system in an SUV and GM's Active Fuel Management cylinder deactivation technology. The two-mode hybrid system was developed with DaimlerChrysler and BMW, reports Trend.
GMC has always stood for engineering excellence, so we're extremely proud to be the first to market with a two-mode hybrid SUV to further improve our segment-leading fuel economy while providing all the performance you expect from GMC, said John Larson, general manager, GMC.
While traditional full hybrid systems offer only one electric mode that is utilized during low-speed driving, the two-mode hybrid system is designed for both city driving and highway driving. The first mode, designed for low speeds, can operate with electric power only, engine power only and any combination of engine and electric power. In the first mode, the systems uses expected hybrid functions like regenerative braking and engine shut-off to improve fuel efficiency. The second mode is primarily used on the highway. In addition to electric assist, the second mode integrates Active Fuel Management, and other electronic controls allow more efficient engine operation. Full eight-cylinder engine power is provided when conditions demand it.
The 2008 GMC Yukon Hybrid is differentiated from its traditional sibling with a new hood, front and rear fascias and a new grille.
The 2008 GMC Yukon Hybrid will offer consumers a 25-percent improvement in overall fuel economy, and will arrive in dealerships toward the end of next year.
