From its debut as a 2002 model, the Chevrolet Avalanche has been defined by its unique Midgate and the one trick it performs: flipping down its Midgate to extend its pickup bed inside the cabin, turning it from a short-bed pickup to a sort of long-bed truck with a partial roof covering its bed. Cadillac builds a similar vehicle dubbed the Escalade EXT.
ForbesAutos deftly describes the 2008 Chevrolet Avalanche as "a cross between a full-size SUV and a full-size pickup truck." Cars.com says the Chevrolet Avalanche 2008 "closely resembles the 2008 Chevrolet Tahoe up front, though with an overall length of 221 inches it's nearly as long as Chevrolet's full-size Suburban SUV." Edmunds comments favorably on the 2008 Chevy Avalanche's "versatile midgate-based body style," while Kelley Blue Book notes that the Chevrolet Avalanche 2008's "monochromatic exterior features wraparound fascias that eliminate bumper-to-body gaps," adding that a "sleek windshield angle extends into a smoother roofline, the front air dam is low and wide and prominent fenders with integrated wheel flares complement the bulging power-dome hood." Edmunds complements the “sleeker exterior styling” in this generation. “The previous Avalanche's body cladding is gone, replaced with integrated rocker panels and bumpers,” Cars.com says. “Key elements of the previous model remain—namely the triangular pillars descending from the cab's C-pillars to its bed.”
The 2008 Chevy Avalanche has a "decent interior," according to Car and Driver; the 2008 Chevrolet Avalanche takes "interior styling cues [that] echo the Tahoe and Suburban, with a curvaceous dashboard," notes Cars.com. They add, “Gone are the boxy dashboard and chintzy controls from the previous version, replaced by a carlike environment that's far beyond GM's previous interiors — and even beyond the current Toyota Sequoia, for that matter.” ForbesAutos simply reports that the 2008 Chevy Avalanche's "nice two-tone interior is crafted from high-quality materials." Car and Driver pays a halfhearted compliment to the “decent interior.”
