What's New for the 2018 GMC Sierra?

The classic GMC Sierra pickup truck has seen some changes coming into the 2018 model year. On the interior of the truck, GMC has added a premium 6-speaker audio system as a standard feature for trim packages available in the Sierra. The Infotainment System with a 7-inch display screen was also added to all base models of the truck. As well, a rearview camera was added as a standard feature on all models the Sierra produces in 2018. On the exterior, GMC added two new colors to their lineup in deep mahogany metallic and red quartz tintcoat. A tire fill alert monitor was added to the tire monitoring system that has been standard on the pickups. Finally, the Sierra is featuring the new performance front brake kit with duralife rotors that limit corrosion on the rotors and make for quieter and smoother braking in the truck.

Trims & Features

The new Sierra trucks come available in many trim packages to consumers. The 2018 GMC Sierra 1500 comes in the base Sierra, SLE, SLT and Denali trim packages. The Sierra HD trim packages in 2500HD and 3500HD come in the same base Sierra, SLE, SLT and Denali trim packages as well. The new Sierra trucks are also offered in a few custom trim packages. The Sierra All Terrain pickup features 18" wheels with all-terrain tires and an underbody shield that are perfect for drivers that prefer to take their trucks off the beaten path of paved roads. Drivers that want to step it up from that package can opt for the All Terrain X package that includes 18" mud-terrain tires and a black sport bar on the bed of the truck. Finally, the Sierra Elevation edition shows a mean look on the road with 20" aluminum wheels and a custom painted grill and bumpers to match the truck all the way around the frame.
