The LS adds body-colour mirrors instead of black ones, and the single-speed transfer case on the LTZ 4WD is now a two-speed. New 20-inch chrome-clad wheels are available as an option. Based on GM’s full-size SUV platform, the Avalanche uses a 5.3-litre V8 with Active Fuel Management, which shuts off half the cylinders under light load for improved fuel economy, mated to a six-speed automatic transmission. The engine is capable of running on E85 ethanol fuel. The Avalanche is rated as a one-ton crew cab truck. The LS and LT trim levels come in two- or four-wheel drive, while the LTZ is 4WD only. Also the basis for the Cadillac Escalade EXT, the Avalanche uses a “Midgate” between the cabin and box. It opens to extend the cargo bed length from 1600 mm to 2500 mm. The cargo box also contains lockable storage compartments with drains.
