Engine
options for the 2012 Chevy Silverado include a V6 and four V8s. The base
V6 features 195 horsepower and 260 pound-feet of torque. The 5.3-liter
V8, available on all models and traditionally the most popular, has 315
horsepower and 335 pounds of torque. The V8 engines
use General Motors' active fuel management system (AFM), which
deactivates four of the eight cylinders when less power is needed. AFM
allows the engine to switch effortlessly between four and eight
cylinders as power requirements change. The 2012
Chevrolet Silverado hybrid has a 6-liter V8 combined with an electric
motor housed in a transmission casing. The V8 uses the AFM system. The
electric motor uses a nickel-metal battery pack that self-charges and
can achieve 30 mph on electricity. The hybrid is available in 2WD or
4WD. All models feature an electronic brake controller
connector located under the dash, which eliminates the need to join
wires when hooking up to a trailer. The 6.2L V8 crew cab with optional
trailer package achieves the maximum towing capacity of 10,600
pounds. The 2012 Chevrolet Silverado is fuel efficient
because of its active fuel management system and E85 compatibility on
some models. Two of the V8s are capable of running on 85 percent ethanol
and 15 percent gas. The horsepower remains the same when using E85 but
the mpg drops by about 20 percent. The V6 1500 2WD
gets 15 miles per gallon in the city and 20 mpg on the highway. The 4WD
model gets 14/18.The 5.3L V8 gets 15/21 for 2WD and 4WD. The 1500 hybrid
gets 21/22 mpg for 2WD and
4WD.
