CHEVROLET SILVERADO 2005 HYBRID CAR
Introduced during the 2004 model year, Chevy Silverado and GMC Sierra Hybrid models provide General Motors fleet and commercial customers with yet another option when considering full-size pickup choices. The Hybrid Silverado and Sierra 1500 models promise up to 10 percent improvement in fuel economy, but they return all the performance and capability that have made these trucks legendary.
  
The hybrid option is available on two- and four-wheel-drive Extended Cab Silverado and Sierra models. They are available in limited quantities to retail customers in California, Washington, and Oregon, Alaska, Nevada and Florida for the 2005 model year.
The Vortec 5300 V-8 engine delivers 295 horsepower (220 kw) and 335 lb.-ft. (463 Nm) of torque – the same as its non-hybrid counterpart. Yet there's something Silverado and Sierra Hybrid provide that standard models do not: these trucks are essentially mobile power-generating stations, with four 120-volt/20-amp electrical auxiliary power outlets (APO). The power outlets are located under the rear seat of the cab and in the pickup bed. Customers can conveniently operate power equipment without taking up the bed space typical portable generators would use.
A uniquely designed, engine-independent electro-hydraulic power steering (EHPS) system provides variable-effort power steering, even when the engine shuts off to conserve fuel. The EHPS “powerpack” integrates an electric motor, a hydraulic pump and an electronic control module; it is powered by the truck's 42-volt battery pack.
Silverado and Sierra Hybrid's advanced multiplexed electrical architecture enables the driver information center to monitor and report on as many as 34 system functions, including service indicators for "Ice Possible" and "Door Ajar," as well as feedback on the operation of the hybrid system. Available redundant steering-wheel controls allow owners to personalize several functions and safely access infotainment options and provide easy access to the OnStar system. A standard automatic temperature control, dual-zone heating, ventilation and air conditioning (HVAC) system provides outstanding comfort. |
