The first generation Avalanche was launched in 2001 and its main attribute was the famous unique foldable mid gate. Thanks to this feature, the Avalanche can be transformed from a five passenger SUV with a 5-foot-3-inch bed into a standard cab pickup with a full 8-foot-1-inch load bed.
The Avalanche is based on the Suburban model and was designed to fill the big gap between the SUVs and pickups. The Chevrolet Avalanche however, is a couple inches longer than the Suburban, but half a foot shorter than the Silverado extended cab.
At the launch the first generation Chevrolet Avalanche was offered with a standard 5300 Vortec V8 engine and comes in both 4x2 and 4x4 flavors.
