The editors of TheCarConnection.com have driven the 2009 GMC Sierra Hybrid, along with other hybrid-powertrain vehicles. And to bring the most useful information to green vehicle shoppers, TheCarConnection.com also highlighted insightful observations from other top review sources.
Following in the footsteps of the new GMC Yukon Hybrid launched last year, a new Hybrid version of the GMC Sierra bows for 2009.
Unless the 2009 GMC Sierra Hybrid is fitted with the optional hybrid decal package, observers will likely not notice it as different from a standard GMC Sierra. That’s not bad; the Sierra was completely redesigned, alongside the Chevrolet Silverado, for 2007, and because of its conservative but tasteful design it still looks fresh today. Hybrid-only features include a tonneau cover over the pickup box that provides a 5 percent reduction in aerodynamic drag for better fuel economy. Although the Sierra is offered in countless configurations, the roomy crew cab body style is the only one available for the Hybrid.
The new powertrain in the 2009 GMC Sierra Hybrid is completely different from what was last offered a couple of years ago. The new two-mode hybrid powertrain mates an all-aluminum 6.0-liter V-8 (with Variable Valve Timing and Active Fuel Management) to an electrically variable transmission (EVT) that utilizes two electric motor/generators and four fixed-ratio gears. A 300-volt nickel-metal-hydride battery pack stores electricity for the system, which altogether is rated at 332 horsepower and 367 pound-feet of torque—bringing acceleration similar to that of the standard Sierra’s 5.3-liter V-8. But most noteworthy, the powertrain brings EPA fuel economy ratings of 21 mpg city, 22 highway with rear-wheel drive, 20/20 mpg for four-wheel drive.
While a Hybrid model might be expected to carry a reduced tow rating, the Sierra Hybrid can pull a very respectable 6,100 pounds in its two-wheel-drive version.
