The GMC Yukon Hybrid is the first full-size SUV hybrid with a state-of-the-art hybrid system using GM’s all-new Electrically Variable Transmission (EVT). GM’s advanced EVT is combined with a 300-volt nickel-metal hydride Energy Storage System, which work in concert with the standard 6.0-liter V8 Gen IV gasoline engine with Active Fuel Management and late intake valve closing technology. The new hybrid system allows the Yukon Hybrid to drive at up to 30 mph on electricity alone and also allows the engine to operate in its more economical V4 mode for longer periods.
The good: The power train in the GMC Yukon Hybrid delivers enormous power and better mileage than comparable SUVs, and can drive the car for short distances under electric power only. The audio and navigation interface is very well designed.
The bad: The navigation system offers no particularly advanced features. There is no Bluetooth cell phone integration, although you can get hands-free calling through OnStar.
