2005 GMC Sierra Review

The GMC Sierra is nearly identical to the Chevy Silverado but features more mature, restrained styling. It's a look that reflects GMC's history of building trucks, and only trucks, that dates back to 1902, nearly a decade before Louis Chevrolet produced his first car.

GMC also offers more options than Chevrolet, including the luxurious Sierra Denali, a suave, uniquely styled, ultra-luxury pickup whose exclusive features include a high-performance 6.0-liter V8 and full-time all-wheel drive. Denali appeared in 2002 as an Extended Cab pickup; for 2005, GMC has transformed Denali into a Crew Cab with four full-size doors.

GMC continues to offer light-duty 1500 Crew Cab models in SLE and SLT trim. With their 5-foot, 8-inch cargo box, Sierra Crew Cabs are no longer than standard-bed, extended-cab models for easier parking and maneuverability. Crew Cab models offer a rear-seat DVD entertainment center as an option, making these pickups an attractive alternative to a full-size SUV.

At any trim level, and with any cab configuration, Sierra offers first-class hauling and towing capabilities. Extended Cabs, with their standard 143-inch wheelbase and optional Quadrasteer four-wheel steering and heavy-duty brakes, make supremely stable tow vehicles, with towing capacities up to 9,000 pounds. The 1500HD Crew Cab, which returns for 2005 after a one-year hiatus, can tow up to 10,200 pounds. Even the plush Denali tows 8,100 pounds.

Yet all Sierras deliver a smooth, comfortable ride among the full-size pickups. Even compared to more recently introduced or re-engineered pickups from Ford, Dodge, and Nissan, the Sierra rides and handles very well. Sierra's current design dates from 1999, but it was significantly refined and updated for 2003, with cleaner engines, a bolder exterior appearance and more comfortable interiors.

The front styling of the GMC Sierra ties it closely to the mid-size GMC Envoy, and to some of the great GMC pickups of the past. The chrome-framed grille consists of three black horizontal bars that prominently display a big red GMC emblem. Chromed front bumpers include two airflow cutouts. Up-level models have a body-colored lower front fascia; base models have a light-charcoal fascia. An optional grille/brush guard adds front-end protection. A single OnStar roof antenna combines the GPS and cell-phone functions.

Compared with the Chevrolet Silverado, GMC's styling is more conservative, more mature, with smoother, more sophisticated lines. Overall, it's a look that a lot of truck buyers like: more upscale than the Chevrolet pickup, more conservative than the Dodge or Ford pickups.

Like the Denali versions of the Yukon and Envoy, Sierra Denali features a distinctive front-end appearance. Its chromed mesh grille looks like something from a hot-rod shop. Projector-beam headlamps and unique front fascia and fog lamps add up-market distinction, along with body color on the door handles, side moldings, tailgate handle, outside mirrors, rear bumper and tonneau cover. Chrome running boards with integral mud guards further distinguish the Denali from other Sierras.

For 2005, nearly all Sierras come with 17-inch wheels: painted steel on work trucks, chromed steel on base and SLE, aluminum on SLT and polished aluminum on Denali. The only exceptions are the 1500HD and the Hybrid, which make do with 16-inch rims. Denali models are available with 20-inch wheels for a stronger styling statement.

The load height (the distance from the ground to the bed) for 2WD Sierra models is just 31.6 inches. For 4WD models, it's 33.7 inches. Those numbers start to look a lot more important when you have to lift something heavy into the pickup bed.

All GMC Sierras are built on the stiffest and lightest truck frame General Motors has ever produced. The frame rails are hydroformed, a process that uses high-pressure hydraulics to shape relatively large steel components. Tubular crossmembers and roll-formed mid-rails increase rigidity further. This stiff structure enhances handling and ride quality immensely, while improving crashworthiness.
