Chevy Silverado Hybrid Pickup 2005 Revs It Up In Performance Parts at Partstrain

Written by Jenny McLane

Vehicles with bigger, less fuel-efficient engines will benefit more from hybrid technology, thus big pickup trucks, vans and SUVs are prime candidates forrepparttar gas-saving benefits of hybrid technology. The Chevy Silverado hybrid pickup feature GM's 5300 Vortec V-8 and Hydra-Matic 4L60-E four-speed automatic transmission, coupled with hybrid technology that delivers 10 to 12 percent improved fuel economy over GM half-ton pickups.

It features a powerful 42-volt lead-acid battery pack underneathrepparttar 142049 rear seat, an auxiliary starter-generator betweenrepparttar 142050 engine andrepparttar 142051 transmission, an electronic control module, and a regenerative braking system, which chargesrepparttar 142052 battery while braking, and coasting.

With an auxiliary generator capability,repparttar 142053 truck's generator can operate whenrepparttar 142054 truck is parked without a key inrepparttar 142055 ignition. The hybrid Chevrolet Silverado and GMC Sierra pickups could power tools or appliances for up to 32 hours non-stop. This design shutsrepparttar 142056 engine down beforerepparttar 142057 tank is emptied, leaving enough gas to drive to a station for refueling. All power supply circuits are protected by a ground fault detection system to prevent overloads and short circuits.

A compact electric motor that generates up to 14,000 watts of continuous electric power makes these pickup trucks more fuel-efficient. The main function ofrepparttar 142058 three deep-cycle lead acid batteries is to assistrepparttar 142059 starter generator to instantly restartrepparttar 142060 engine. Whenrepparttar 142061 Silverado Hybrid comes to a stop while in Drive or Park,repparttar 142062 engine will automatically shut off. Whenrepparttar 142063 driver takes his/her foot offrepparttar 142064 brake and puts it onrepparttar 142065 accelerator,repparttar 142066 engine re-starts automatically and almost seamlessly.

GMC Sierra Hybrid 2005 Accentuated with GMC Parts from Parts Train

A standard Vortec 5300 5.3-liter V8 engine powersrepparttar Sierra Hybrid and a 4-speed Hydra-Matic automatic transmission coupled withrepparttar 142048 full-size truck segment’s first hybrid propulsion technology for improved fuel economy.

The Sierra hybrid uses electric power even less frequently. Its gasoline engine can shut down whenrepparttar 142049 car is stopped (actually, when it's braking to a stop, below 13 mph or so) and-that's it. The batteries (three 14-volt units plusrepparttar 142050 standard 12-volt) cannot powerrepparttar 142051 truck at low speeds. Nor do they help outrepparttar 142052 gasoline engine, which therefore can't be any smaller. It'srepparttar 142053 same 5.3-liter V-8 GM pickup buyers know and love. Because ofrepparttar 142054 limited nature of this hybrid system,repparttar 142055 benefits are mild: roughly 2 mpg in city driving and 1 mpg duringrepparttar 142056 EPA's highway cycle.

The system replacesrepparttar 142057 traditional starter motor and alternator with a compact 14-kw electric induction motor or starter generator integrated betweenrepparttar 142058 engine and transmission. The starter generator provides fast, quiet starting power and allowsrepparttar 142059 gasoline engine to automatically start and stop under certain conditions to conserve fuel.

The Sierra Hybrid also offers four 120-volt/20-amp electrical auxiliary power outlets located underrepparttar 142060 rear seat and inrepparttar 142061 pickup bed. Becauserepparttar 142062 5.3-liter V-8 isrepparttar 142063 same as that in non-hybrid pickups, its power and torque outputs arerepparttar 142064 same (295 horsepower, 325 pound-feet of torque). Acceleration, towing, and payload are undiminished. The extra hybrid gear takes up very little space-the biggest component,repparttar 142065 three extra batteries, is underrepparttar 142066 rear seat. One interesting feature ofrepparttar 142067 hybrid trucks are its four, 120-volt 20-amp AC power outlets inrepparttar 142068 cargo bed andrepparttar 142069 rear seat; butrepparttar 142070 engine must be running in order to use them.
