Vehicle Overview
When it debuted for 2002, the Avalanche upset the trend of making more-SUV-like pickups. Chevy simply made its popular Suburban into a pickup; it gave the Avalanche more versatility, but didn't lose any of the SUV's inherent creature comforts. The Avalanche features a midgate that expands the cargo area into the passenger cab. By removing the midgate and folding down the second-row seat, the cargo floor extends from 5 feet, 3 inches to more than 8 feet. The cargo bed also features lockable, side-mounted storage. A locking tailgate and cargo cover increase the secured-storage options even more. The Avalanche is available in LS, LT and LTZ trim levels and in two- and four-wheel drive.

New for 2010
GM has dropped the 6.0-liter V-8 engine from the Avalanche lineup, leaving the 5.3-liter flex-fuel V-8 as the only engine. It's paired with GM's six-speed automatic, giving drivers two overdrive gears for better highway mileage. A 3.08:1 rear axle is now standard for both two- and four-wheel-drive models, enabling reduced engine speed during cruising to improve fuel economy. Inside, Chevy has added a USB port that allows you to control your MP3 player through the truck's stereo.

The Avalanche doesn't mind flaunting its split personality. It's neither an SUV nor a pickup it's both. It has the bold but familiar front-end styling found on Chevy's truck-based products. Setting the Avalanche apart are distinctive sails that connect the cab to the bed and emphasize the smooth roofline and exterior length. The only real problem with the design is rearward visibility. Parking and backing up in tight spots can be tough, so the available sensors and backup camera are invaluable.

The 1LT model now includes dual-zone automatic climate control, power-adjustable pedals, remote vehicle start and a heavy-duty rear locking differential.

The interior's centerpiece is the fold-down rear seat and the removable midgate. The rear glass can be removed separately from the main midgate for an open-air effect.
