Powers Vortec 5300 V8 engine standard 5.3-liter , the Sierra Hybrid and 4-speed Hydra-Matic automatic transmission , along with the first hybrid propulsion technology segment of full-size trucks for better fuel economy.

The Sierra hybrid uses electric power even less frequently . Its gasoline engine can shut down when the car is stationary (in fact, during braking to stop , less than 13 miles per hour or more) and that’s it . The batteries ( three units of 14 volts and 12 volt standard ) can not supply the low-speed truck . Nor help the gasoline engine, which can be very small . This is the same 5.3-liter V – 8 GM pickup buyers know and love. Due to the limited nature of this hybrid system , the benefits are slight: about 2 miles per gallon in city and 1 mpg on the EPA highway cycle .

The system replaces the starter and alternator with a conventional induction motor 14 KW compact electric or integrated between the engine and generator start transmission . The starter generator provides power for fast, quiet starting and allows the gasoline engine to automatically start and stop under certain conditions to conserve fuel .

Sierra Hybrid also offers four electrical auxiliary power outlets 120-volt/20-amp located under the rear seat and the truck bed . Because the 5.3 – liter V – 8 is the same as that of non – hybrid trucks , power output and torque are the same ( 295 horsepower , 325 pounds -feet of torque) . Acceleration, towing and payload are intact. The additional hybrid train takes up very little space – the most important component , the three extra batteries , is under the rear seat . An interesting feature of the hybrid trucks are its four , 120 volt , 20 amp AC power outlets in the cargo box and the rear seat , but the engine must be running for use.

As in hybrid cars, the gasoline engine is stopped at traffic lights to save fuel , and an electric motor restarts the engine when the accelerator pedal is depressed. Unlike most hybrids , the electric motor does not allow to propel the vehicle . The system includes a unique feature for commercial users and picnic tailgaters : a generator that supplies power to 120 -volt electrical accessories work.

Available in California, Washington, Oregon , Alaska , Nevada and Florida, the Sierra Hybrid delivers up to 10 percent better fuel economy with the same power and performance as the 5.3-liter V8 . In fact, that same power of hybrid engines , developing the same 295 horsepower and 335 lb- ft of torque.
