Vehicles with
bigger, less fuel-efficient engines will benefit more from hybrid
technology, thus big pickup trucks, vans and SUVs are prime candidates
for the 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 underneath the rear seat,
an auxiliary starter-generator between the engine and the transmission,
an electronic control module, and a regenerative braking system,
which charges the battery while braking, and coasting.
With an auxiliary
generator capability, the truck's generator can operate when the
truck is parked without a key in the ignition. The hybrid Chevrolet
Silverado and GMC Sierra pickups could power tools or appliances
for up to 32 hours non-stop. This design shuts the engine down before
the 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
of the three deep-cycle lead acid batteries is to assist the starter
generator to instantly restart the engine. When the Silverado Hybrid
comes to a stop while in Drive or Park, the engine will automatically
shut off. When the driver takes his/her foot off the brake and puts
it on the accelerator, the engine re-starts automatically and almost
seamlessly.
One feature
of GM's Hybrid pickups that is likely to attract buyers is its two
120 volt power outlets inside the box near the tailgate, and another
two 120 volt outlets inside the rear cab. These can be used for
power tools, compressors, generators, heaters, appliances or any
other electrical appliance. The outlets can be deactivated with
a button on the dashboard to avoid any unauthorized use of the external
120 volts outlets.
The Silverado
Hybrid extended cab is a comfortable, smooth-riding pickup with
a quiet, V8 engine, a roomy cab with good ventilation and excellent
outward visibility, and a rugged durable chassis.
GM's new gas-electric
pickup truck, the Chevy Silverado Hybrid pickup, is the latest vehicle
to take advantage of the gas-saving benefits of hybrid technology.
