Fast on the heels of the all-new next-generation Yukon SUV introduced last year, GMC makes another leap forward in the full-size SUV segment with the introduction of the Yukon Hybrid.

It features the first production 2-Mode full hybrid propulsion system, which offers a 25 percent overall improvement in fuel economy. The large GMC SUV Hybrid is built on GM's full-size SUV platform, which features a fully boxed frame, coil-over-shock front suspension, rack-and-pinion steering and an all-new premium interior system that bolsters the vehicle's comfort, quality and capability.
Available in two- and four-wheel drive, power for the Yukon Hybrid is generated by a Vortec 6.0L V-8 engine with Active Fuel Management cylinder deactivation technology and automatic transmission.
The 2-Mode full hybrid system leverages automatic transmission technology and electronic controls in an integrated, powerful and compact system that can be used with both gasoline and diesel engines. Derived from GM's 2-Mode full hybrid system used in transit buses, the design integrates proven automatic transmission technology with a patented hybrid-electric drive system.
The 2-Mode system features two models optimized for city and highway driving. In the first mode, at low speed and light loads, the vehicle can operate in three ways: electric power only, engine power only or in any combination of engine and electric power. The second mode is used primarily at highway speeds. In addition to electric assist, the second mode provides full eight-cylinder engine power when conditions demand it, such as when passing, pulling a trailer or climbing a steep grade. The 300-volt battery pack provides electric power for the system and is designed to fit in the vehicle without compromising passenger space. Special converters located under the vehicle's hood convert the motors' AC output to DC current to power conventional 12-volt accessories, such as interior lighting, climate control and the radio. The vehicle's gasoline engine provides power to charge the battery pack, so the vehicle doesn't have to be plugged in to keep the battery pack charged up.
EPA fuel economy estimate:
City and highway: 20 to 22 mpg (Source: Edmunds.com)
Starting MSRP: $50,045 – $52,855
