Chevy Silverado Hybrid Parts and Chevy Silverado Hybrid Accessories

Silverado Hybrid

GM launched a hybrid version of the Silverado/Sierra in 2005, becoming the first ever GM hybrid passenger vehicle.

Known within GM as the Parallel Hybrid Truck or PHT it is not actually a parallel hybrid by the current defintition, but a type of mild hybrid design. The electric motor housed within the transmission flywheel housing, serves only to provide engine cranking/starting, battery charging, and powering accessories.

The engine automatically shuts down as the truck comes to a stop and uses 36 Volt electric power to the starter/generator unit to restart the engine as the brake pedal is released. Besides the typical 12V automotive battery the PHT uses three additional 12 Volt valve regulated lead acid (VRLA) batteries mounted under the rear seat to store and provide power. The truck uses a 5.3 L Vortec 5300 V8 for primary propulsion power.

The PHT features four 120 volt 20 amp AC outlets, two in the bed and two inside the cab under the rear seat. These are particularly interesting to the building/construction contractor market, since they often require AC power when on the job. Additionally, the extra reserves of power for the accessories make this truck well-suited to that market, where trucks often sit at idle for hours at a time.

In 2005 the truck was offered at retail in Alaska, California, Florida, Nevada, Oregon, Washington and Canada. For 2006-07 the truck was generally available to retail buyers throughout North America. The Parallel Hybrid Truck was discontinued for the 2008 model year with the release of the GMT900 truck line, however General Motors offers the Chevrolet Silvrado and GMC Sierra equipped with a Two-Mode Hybrid powertrain for the 2009 model year.
