TheSilverado is a vastly different beast than the gas-powered versions of the full-size pickup truck. Its advanced two-mode powertrain starts with an all-aluminum 6.0-liter V-8 featuring variable valve timing and cylinder deactivation. To that, GM adds an electrically variable transmission (EVT) with two electric motor/generators and four fixed-ratio gears, as well as a 300-volt nickel-metal-hydride battery pack.
In all, thesystem is rated at 332 horsepower and 367 pound-feet of torque, which pushes EPA fuel economy to 21/22 mpg for two-wheel-drive models, and 20/20 mpg with 4WD. Driving the Hybrid is remarkably similar to driving the Silverado with the 5.3-liter V-8 engine--that is, except for the almost absurd smoothness and quietness as the Silverado runs up to 27 mph on battery power alone. The Silverado brakes are powerful and recapture energy to charge the batteries.
Even saddled with more curb weight, thetows 6,100 pounds with 2WD, or 5,900 pounds with automatic dual-range four-wheel drive.
