The 2012 Chevrolet Avalanche is a four-door, full-size sport utility truck that combines the comfort and passenger capacity of an SUV with the cargo flexibility of a pickup truck. It's available in three trims: LS, LT, and LTZ. Under the hood, the Avalanche is powered by a 5.3-liter V8 engine that produces 320 horsepower and 335 lb-ft of torque. All models are equipped with a six-speed automatic transmission and come standard with rear-wheel drive, though four-wheel drive is optional. A standout feature of the Avalanche is its 'midgate' wall, which allows the rear cab area to be converted into additional cargo space. Inside, the Avalanche boasts a tech-rich interior with a 7-inch touchscreen, Bluetooth, and available navigation system. Safety features include a rear-view camera, rear parking sensors, and a full complement of airbags.
