What's New

The 2008 GMC Sierra has only minor changes such as the satellite radio that becomes standard equipment and an integrated trailer brake controller as an option.

Exterior

The headlights are vertically stacked with a tall bumper under them. The 2008 GMC Sierra has a tall squared-off nose and the windshield slants back. These features give it an aerodynamic design, improving fuel economy. The truck has an upright and chrome grille surround. In the middle of the grille sit dark horizontal bars with the GMC emblem set in the middle. A wide air intake wraps around the truck, extending from the front lower edge to the front wheel wells. Round fog lights sit on the bumper. The Denali has its own unique chrome grille with the air vent under the front bumper painted to match.

The profile view shows elongated fender flares that run down below the headlights. The cargo bed has high sides and the tailgate is sculpted with stacked taillights on each side.

A system to organize cargo in the bed with rails and various controlling boxes, dividers, and tie-downs proves to be a very beneficial feature.

Interior

The model style labeled the “Pure Pickup"" provides a work truck interior with less luxury and more useful truck features such as a dual glove box. Larger door handles and switchgear keep a driver wearing gloves in mind. In addition, it has a 40/20/40-split front bench seat with the center section capable of folding down to incorporate a hefty storage compartment and armrest.

The “Luxury Style"" version of the 2008 GMC Sierra includes unique features as well, such as audio and ventilation controls within easier reach of the front passenger. It also uses two bucket seats and a center console with various storage areas.

Both models have dashboards that boost analog instrumentation with simple controls. However, the upper models’ central dash have a small button that requires some getting used to.

Performance & Handling

The Sierra feels comfortable and easy to drive. The supple suspension and quiet cabin make it suitable for an extended trip. Depending on the cab size, the 2005 GMC Sierra offers various engine sizes, such as a 195-horsepower, 4.3-liter V-6; a 295-horsepower, 4.8-liter V-8; a 315-horsepower, 5.3-liter V-8; and a 367-horsepower six-liter V-8. Cargo bed lengths measure 6.5 or 8.1 feet for the regular and extended cabs and 8.5 feet for the crew cab. All engines pair with a four-speed automatic transmission.

In addition, the top-end Denali offers a crew cab and a 403-horsepower, 6.2-liter V-8 and a six-speed automatic transmission. It offers a choice of two four-wheel drive systems, which include a part-time setup only engaged on dry pavement and the Autotrac for any surface. Both have off-road capability with low range gearing. The Sierra also offers a choice of four suspensions, including the Z83 and Z85 that have optimum ride comfort, the Z60 for street performance, and the Z71 for off-roading.

Safety

Standard equipment on the 2008 GMC Sierra includes anti-lock brakes with front discs and rear drums. All-disc setup provides an option with the Max Trailering Package and on the Denali. Standard on the crew cabs and optional on the extended cab is a stability control system with roll-mitigating technology. Most models have the option of side-curtain airbags and adjustable pedals.

The Sierra receives a five-star rating for front-occupant protection in head-on collisions conducted by government agencies.
