Chevrolet Silverado

General
Motors is expanding its line of full-size hybrid vehicles by rolling out a new
hybrid version of the Chevrolet Silverado. While the last Silverado Hybrid's
claim to fame was its ability to act as a worksite generator, the all-new 2009
version is designed to deliver markedly improved fuel economy. Powered by an
advanced two-mode hybrid powertrain. The all-aluminum 6.0-liter V-8 features
variable valve timing and Active Fuel Management, which shuts down half of the
engine's cylinders during coasting and cruising.
The hybrid electrically
variable transmission (EVT) utilizes two electric motor/generators and four
fixed-ratio gears. Electricity for the motors is stored in a 300-volt nickel-metal-hydride
battery pack.GM claims that the truck will see a 40% increase in city fuel
economy and a 25% overall bump compared to its non-hybrid sibling. It can run
in all-electric mode up to 30 mph, even when towing (up to 6,100 lbs). The 2009
Chevrolet Silverado Hybrid is capable of towing 6,100 pounds when outfitted as
a two-wheel-drive unit, and only 200 pounds less when all four wheels are
driven via a two-speed, off-road-capable transfer case. Depending on the state
of battery charge, all-electric operation can continue for up to one full mile.
GM engineers also implemented a number of improvements to make driving quieter
under all conditions, which is great for the occupants and makes for a more
seamless transition between electric-only and engine-on modes.
The cabin
of the Silverado Hybrid is much like that of the regular Silverado. The low-set
instrument panel feels upscale for a pickup, and front seats are generous in
comfort and support. Interior build quality and fit/finish on the 2009
Silverado Hybrid examples we drove are excellent.
The
Silverado Hybrid is offered in the crew cab body style on both 2WD and 4WD
models. Each model is equipped with several standard, popular features,
including StabiliTrak electronic stability control system, a locking rear axle
and a trailering package.
The new
Silverado Hybrid includes standard equipment far beyond what one might find on
a standard work truck, including dual-zone air conditioning, power windows,
remote keyless entry, AM/FM audio system with MP3-capable CD player, and a
tilting, leather-wrapped steering wheel with controls.
Hybrid-only features
include a standard tonneau cover over the pickup box that provides a 5 percent
reduction in aerodynamic drag for better fuel economy.
We
recently tested a 2009 Chevy Silverado 4×4 Hybrid rolling in imperial blue
metallic paint and found the new pickup to deliver nearly everything we have
come to know and admire in a Chevy fullsize pickup, save a little bit of
payload and towing capability tradeoff.
