The GMC Sierra didn't receive any significant changes for its 2012 model year, yet a number of minor upgrades were made. All versions of the truck now come with a spare wheel lock, and the base Work Truck variant now features cruise control. SLT and SLE versions received a three-bar chrome grille. The navigation radio became hard-drive based and now features CD/DVD drive and USB port. The GMC Sierra continues to provide a proven combination of excellent power, capability, and durability. The model employs a broad line of potent power plants that deliver superior performance and efficiency thanks to advanced technologies such as VVT and active fuel management. A 4.3 L V6 is the base engine, capable of delivering 195 hp. The line-topping power plant is a 6.2 L V8 good for 403 hp. Two gearboxes are offered – 4-speed and 6-speed automatic.
The 2012 GMC Sierra uses a fully boxed frame featuring a hydroformed front section, rack-and-pinion steering, and coil-over-shock suspension setup in front. The frame decreases vibrations transmitted to the model’s cabin. The truck also comes with wide tracks, both front and rear, for increased stability and handling. The 2012 Sierra offers 5 suspension system options designed to meet different needs. The 4-channel ABS is standard for the vehicle, connected to the corporate StabiliTrak system. The latter is an electronic stability control system intended to decrease the risk of rollover. It is also standard for all versions. All models except for V6-powered ones can be fitted with an integrated trailer brake controller. A locking rear differential (automatic) is offered as well - it is optional for the Work Truck, SL and SLE and standard on higher grades.
The 2012 GMC Sierra offers two interior options for different needs. The SL, SLE and Work Truck trims feature a “pure pickup” interior for working purposes with large door handles and controls that can be easily operated by gloved hands. The SLT and Denali come with luxury interiors inspired by full-size SUVs by the automaker, featuring distinct trim, unique dash and door panels, and large-capacity center console offering over 20 liters of storage.
