General Motors has announced that the redesigned 2014
Chevrolet Silverado and 2014 GMC Sierra full-size pickup trucks will return up
to 24 mpg on the highway when equipped with the new 285-horsepower, 4.3-liter
V-6 engine and rear-wheel drive, regardless of cab configuration.
The fuel-economy rating makes the new Silverado and Sierra
models nearly the most fuel-efficient, gasoline-engine pickups available. Only
the Ram 1500 HFE (High Fuel Economy) in regular-cab configuration does better,
at 25 mpg on the highway. However, the Ram 1500's maximum payload and tow
ratings are 1,930 lbs. and 6,500 lbs., respectively, whereas the Chevy and GMC
can haul 2,108 lbs. in the bed and tow up to 7,200 lbs. of trailer weight.
"Budget-conscious customers often buy V-6 pickups to do real work, and the 2014 Silverado with the 4.3-liter EcoTec3 V-6 will combine unmatched capability and excellent fuel economy with surprising levels of refinement," said Jeff Luke, executive chief engineer at General Motors. "Our V-6 has torque where you need it to get the job done, with 230 lb.-ft. of torque available at 1,200 rpm, and more torque available from 2,400 to 5,300 rpm than competitive V-6s make at their peak."
In addition to making 285 horsepower at 5,300 rpm, the new direct-injection, 4.3-liter V-6 engine generates 305 lb.-ft. of torque at 3,900 rpm. Standard Active Fuel Management technology switches the engine to 4-cylinder operation under low-load driving conditions, such as when cruising on the highway without payload in the bed or a trailer attached to the back of the truck.
General Motors said that the V-6 delivers 18 mpg in the city, 24 mpg on the highway, and 19 mpg in combined driving with 2-wheel drive. With 4-wheel drive, the V-6 returns 17 mpg in the city, 22 mpg on the highway, and 18 mpg in combined driving.
Previously, the most fuel-efficient GM full-size trucks were the 2013 Silverado and Sierra Hybrid models, priced from $42,130 and available only in a crew cab configuration.
Equipped with a gas-electric hybrid powertrain pairing a 6.0-liter V-8 engine with a 300-volt nickel-metal hydride battery pack and an electrically variable transmission containing twin 60-kW electric motors, the hybrid trucks were rated to get 20 mpg in the city, 23 mpg on the highway, and 21 mpg in combined driving. Maximum payload capacity for the hybrid trucks measured 1,527 lbs., and maximum tow capacity was 6,100 lbs., well short of the new V-6 engine.
