The 2010 GMC Sierra Hybrid is almost unique: it, and the similar Chevy Silverado Hybrid, are the only gas-electric pickups sold in America.
Casual observers probably won't notice the Hybrid at first; aside from some badges and decals, the Hybrid's only cosmetic changes are 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.
The Sierra's two-modepowertrain 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.
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.
