LOS ANGELES — When it hits the market in late 2008, Chevy’s new Silverado Hybrid is expected to be the most fuel-efficient full-size pickup yet—an impressive distinction for the domestic workhorse. Working in conjunction with 300-volt nickel metal hydride batteries that sit beneath the rear seats, the 6.0-liter V8 powerplant is capable of operating on four cylinders for economy, or shutting off completely at speeds of up to 30 mph. The two-mode 
hybrid system uses regenerative braking for fuel economy, and will be capable of operation while towing up to 6100 pounds. An electrically variable transmission (EVT) rounds out the powertrain setup, enhancing seamless delivery of power for either 2WD or 4WD crew cab models.
The Silverado Hybrid should also ride quietly, thanks to low-rolling resistance tires, electrically powered HVAC and steering systems, and internal fans designed to cool the NiMH batteries. Its Z85 suspension is specially tuned for hybrid duty, and a new hydraulic body mount smooths out road surface irregularities. Long-haul drivers might benefit less from the hybrid system, but should appreciate the 26-gallon fuel tank, which enables a theoretical cruising range of more than 500 miles. Underneath its imposing exterior proportions, the 2009 Chevrolet Silverado Hybrid promises to offer a unique combination of fuel economy, rugged utility and cruising comfort. —Basem Wasef
