The Chevrolet Avalanche is a very recognizable full-size, four-door sport utility truck with a long chassis used on other Chevrolet trucks, SUVs, and the Cadillac Escalade. It has a front-engine rear or four-wheel drive layout. The Avalanche was first introduced in 2001 and is currently still in production in its second generation.
The 2008 Avalanche has a quality interior and is very comfortable. There is low noise road, even at highway speeds. The Avalanche offers many convenient storage options and the bed is rugged and vastly improved over past models.
Fuel economy is perhaps the biggest problem with the 2008 models. Many also criticized the pricing when compared to vehicles that are similarly equipped. The 5.3-liter engine does not accelerate as well as most consumers would hope. For families with children, there are some issues fitting specific child seat models in the 2008 Avalanche.
Many drivers and critics simply love the look of the Chevrolet Avalanche, and the 2008 model follows the basic layout of past models. The engine power is in the middle range for the class, and other than poor gas mileage and minor problems, the Avalanche is in the middle of the pack for its category.

Most of the changes to the Chevrolet Avalanche for the most recent generation were introduced in 2007; however, there were a handful of changes from the 2007 to the 2008 models, including the addition of side-curtain airbags as standard, electronic stability control, a standard V-8 engine, and newly available four-wheel-drive options. Only minor changes were made to the car’s exterior.
The exterior of the 2008 Chevrolet Avalanche is very similar to the 2007 version. There are three trim levels: LS base trim, LT, and LTZ. The 2008 versions introduced two new colors: Blue Granite Metallic and Deep Ruby Metallic. Seventeen-inch alloy wheels come standard, and 20-inch alloy wheels are available with upgraded models.
There are two rows of seats, and the Avalanche can accommodate up to six passengers. The rear seats may also be folded down for more cargo room. Leather interior is optional and the Avalanche comes with climate control, power seats, optional navigation, and optional DVD entertainment system for the rear seat.
Performance & Handling
All 2008 Avalanche models use a four-speed automatic transmission overdrive. Available engines include a 310-horsepower 5.3-liter V-8 flexible E85 engine, 320-horsepower 5.3-liter V-8 flexible E85 engine, and a 320-horsepower 5.3-liter V-8 gas engine, and the 366-horsepower six-liter V-8 gas engine.
The Avalanche’s handling is moderate for a full-size truck. It has good acceleration and descent power. On the open road and once up to speed, the Avalanche feels smooth and powerful. According to some critics, limited visibility and poor handling make city driving and parking a hassle.
Side-curtain airbags are now standard with the 2008 lineup. Other features include anti-lock brakes (ABS), electronic stability, rollover mitigation, and individually operating brakes.
