- Since the 1930s, Chevrolet has been producing pickup trucks. In 1962, "C" and "K" monikers were given to designate the drive types of each model: "C" for rear-wheel drive, and "K" for four-wheel drive. In 1998, the C/K designators were replaced by the Silverado and Sierra names. Hybrid technology was merged with the Silverado in 2005, and the Silverado 1500 Hybrid is still produced as of October 2010. The 2011 Silverado 1500 Hyrbrid comes in two models: the 1HY and 2HY.
Engine and Fuel Economy
- Each model of the 2011 Silverado 1500 Hybrid comes with a 332-horsepower, 6.0-liter V-8 engine. The engine achieves maximum horsepower at 5,100 rpm, while maximum torque is reached at 4,100 rpm with 367 ft.-lb. With variable valve timing, a 120-kilowatt electric motor, regenerative braking technology and deceleration fuel cutoff, the engine can achieve about 21 mpg city and 22 mpg highway. A 26-gallon fuel tank allows for an overall range of about 520 to 600 miles.
Transmission and Drive Type
- The 1HY and 2HY models come with a four-speed shiftable transmission with overdrive, which allows the engine to achieve greater fuel efficiency while reducing engine wear. Each model comes available as rear-wheel drive or four-wheel drive, with four-wheel disc brakes, gas-pressurized shocks, electronic stability control and rack-and-pinion steering as standard features.
- Most of the (few) differences between the two models lie in the interior. The 1HY sports cloth seating for up to six people, with front and rear bench seats. The 2HY comes with leather front bucket and rear bench seats that can seat up to five people. A power sunroof is available for the 2HY, while both models come with power locks, power windows and dual-zone front air conditioning.
