- Service & Repair
The GMC Sierra 1500 and Chevrolet Silverado share the same platform, but the GMC product is often positioned as a more upscale offering. Mechanically, the trucks are the same. There might be slight differences in curb weight and payload, but they share the same powertrain and chassis components. There are five engines and five suspensions in the lineup.
The Sierra comes in regular, extended and crew-cab forms. Standard (6-foot, 6-inch) and long (8-foot) cargo beds are available on regular and extended cabs, while the crew cab gets a short (5-foot, 9-inch) bed. All configurations are available in two- or four-wheel drive. The Sierra comes in five trim levels: Work Truck, SL (crew cab only), SLE, SLT and Denali.
Most V-8 models are rated to tow around 9,000 pounds, but some models get more than 10,000 pounds with an enhanced trailering package.
New for 2011
There are only minor changes for the 2011 Sierra half-ton pickup. The Sierra gets the latest OnStar 9.0 system, revised exterior color offerings and insulating enhancements that help reduce wind noise.
While GM is trying to differentiate the Silverado and Sierra, the common silhouette is hard to overcome, even with unique front fenders, grille, bumpers, headlamps, cargo box and taillamps. The upscale Denali trim features a unique chrome grille and wheels. Exterior features include:
The Sierra showcases two different interior designs. Work Truck and SLE models are more utility-minded, with large controls and door handles that can be operated while wearing gloves. The SLT offers upgraded materials and a different dash design. The Sierra's cab is inviting, spacious and well-organized. Leather seating is available on the SLE and standard on the SLT. The SLT also gets a Bose stereo, a 10-way power-adjustable driver's seat and a heated windshield-washer system. Denali trim is the most luxurious package available for a GM pickup with upgraded trim and materials. Interior features include:
