Long regarded as the twin of the Chevrolet Silverado, the 2008 GMC Sierra 1500 offers more differentiation from its General Motors stable-mate in looks, while sharing the same basic architecture and engine choices. Exclusive to the GMC Sierra line, though, is the Denali trim level that brings with it a variety of power and luxury features. Looking to extend their leadership in the pickup truck segment, GM engineers and designers have created a new breed of pickup, one offering an improved chassis, more precise steering and not one but two quieter, more upscale interiors. The Sierra also delivers segment-leading fuel economy thanks to the new line of Active Fuel Management-equipped V8 engines.You'll Like This Car If...

Sufficient power and surprising ride comfort are two hallmarks of the 2008 GMC Sierra 1500. Riding on a fully-boxed frame for more chassis stiffness, with coil-over-shock front suspension and rack-and-pinion steering, the big pickup truck is surprisingly nimble and easy to maneuver. Our lengthy test drive took us over rough, washboard gravel roads, yet the Sierra's cabin retained library-like calm and quiet. We found it hard to choose between the "pure pickup" interior and the "luxury-inspired" interior, because both were handsome and functional. While the available 4.3-liter V6 is no doubt adequate, the Sierra can also be equipped with a variety of V8 engines, most with 5.3-liter displacement, while the Denali features its own 6.2-liter variable-valve-timing engine. Power delivery with each V8 engine we tested was more than ample, though we have to admit we liked the pure power of the 6.0-liter and 6.2-liter V8s. The StabiliTrak electronic stability control system is welcome standard equipment on crew-cab models, and it is available on extended-cab models as an option.Favorite Features
