MSRP: From $ 51,185Powertrains and Performance
The 2010 GMC Yukon Hybrid is available with rear-wheel or four-wheel drive. Both models utilize a 6.0-liter V8 engine coupled to a pair of 60-kilowatt electric motors located inside what GM calls an electrically variable transmission. Together, they produce 332 horsepower and 367 pound-feet of torque. The system can accelerate the Yukon up to speeds of approximately 25 mph using electricity only, while the V8's cylinder-deactivation system helps reduce fuel consumption at higher speeds. Regenerative braking replenishes the batteries by capturing energy normally lost when you come to a stop.
Fuel economy ratings stand at 21 mpg city/22 mpg highway and 22 mpg combined for rear-wheel-drive Yukon Hybrids, with 4WD versions earning identical numbers except combined, which is just 1 mpg less. Maximum towing capacity for a properly equipped 4WD model is 6,000 pounds.
Driving Impressions
It's not a stretch to say that driving the 2010 GMC Yukon Hybrid feels like being behind the wheel of a 5,600-pound Prius. There's the same eerie quiet when accelerating and braking, as the gas engine shuts off to let the electric motors do their thing. Although it's a tad strange, the result is a quiet cabin, while transitions between gas and electric modes, and eight- and four-cylinder mode, are either undetectable or easy to ignore.
Although the Hybrid is the most powerful Yukon available, it's also the heaviest, so don't expect particularly brisk acceleration. Also, the transmission isn't what we'd call responsive; there can be a notable delay when you ask for full power. Handling is about what you'd expect -- safe but ponderous. Most crossovers are notably more carlike from behind the wheel. The Yukon's cabin remains fairly quiet at speed, though, and the ride is relatively smooth for a truck-based SUV.
