2004 Chevrolet Avalanche Overview
Overall User Score
Based on 22 reviews
The Chevy Avalanche returned with minimal changes for the 2004 model year after a number of minor alterations and upgrades for 2003. The only notable change is a new optional anti-skid system on the two-wheel-drive versions of the truck.
The Avalanche continued to receive positive reviews for its ample passenger and cargo room, interior and bed storage space, and impressive towing capacities. The "crossover pickup," as Chevy has dubbed it, has been in relatively high demand since its 2001 debut, largely because of its unique styling. Yet reviewers have found that the Avalanche's road manners are more pleasant than some might expect, and it was even named Motor Trend magazine's SUV of the Year for 2002. Its refinement is similar to that of the Suburban, as the two massive vehicles share the same engines, platforms, brakes, and transmissions.
Like the Suburban, this popular SUV's downside is fuel economy. A 4WD Avalanche will average in the low teens for mixed-driving miles-per gallon. Road testers have also warned that the steering could be more responsive, and there is some palpable suspension float on rougher surfaces. According to owners, some common trouble spots include transmission slippage and an occasionally faulty blower motor.
The Avalanche has an unladen weight of 5,437 pounds and stretches over 18 feet in length. Chevy offered two different powerplant options for the massive SUV, distinguished from one another by the common 1500 and 2500 badges. A 5.3-liter V8 powers the Avalanche 1500, making 285 horsepower and 325 pound-feet of torque. The Avalanche 2500 gets an 8.1-liter V8 that produces 340 horsepower and 455 pound-feet of torque. A four-speed automatic transmission is paired with both engines. Towing capacity is 8,300 pounds on the 1500 model and 12,000 with the 2500.
Although there are no specific trim levels, buyers do get a choice of two- or four-wheel drive, and between 1500 and 2500 for power. There are no cab-size or bed-length variations for this vehicle. An optional Z71 suspension package provides a more trail-oriented feel, while a Z66 package for the RWD 1500 puts the focus on street performance. Other options include OnStar, leather upholstery, a sunroof, and a special North Face appearance package (1500 only).
