Second-generation Chevrolet Avalanche trucks are built on the GMT900 platform and feature a 5.3-liter Vortec V8 engine. The 2013 Chevy Avalanche has a six-speed SL80 automatic transmission, optional four-wheel drive and achieves 21 miles per gallon on the highway. It is available in three trim levels.
The Chevy Avalanche shares its GMT900 platform with other GM trucks and SUVs, including the Cadillac Escalade, Chevy Tahoe, Chevy Suburban and Chevy Silverado. The LC9 V8 engine delivers 320 horsepower and 335 pounds of torque per foot. The Avalanche's six-speed Hydra-Matic transmission provides smooth shifting and quick acceleration.
The Chevy Avalanche features seating for five, with a cabin almost identical to the Chevy Tahoe and Suburban. The LT trim level adds leather upholstery and heated front seats, while LTZ models include an additional cooling seat feature. The top-of-the-line LTZ trim level also adds an eight-speaker Bose surround sound system, a security alarm and 20-inch alloy wheels. For cargo space, the Avalanche has a bed measuring 5 feet and 3 inches long. The cabin's rear bench-seat folds down and the mid-gate panel opens for added pass-through cargo space.
A Z71-package option improves the Avalanche's suspension for better off-road performance, adds an automatic locking rear differential and includes exterior appearance upgrades. For the Avalanche's final year of production, Chevy offered a Black Diamond package for 2013 models. The Black Diamond Edition includes commemorative badges and emblems on and within the vehicle. 2013 Avalanche models also have an exclusive paint color option of Fairway Green Metallic.
