2018 GMC Sierra 1500 SLT Black Photos

The 2018 GMC Sierra 1500 did not get big changes this year, and actually did not need it. Sierra, who shares the design with the Chevy Silverado, is very capable when it comes to towing and is an impressive and luxurious truck.

Offered with three different engines and with multiple bed and body configurations, the 2018 GMC Sierra 1500 can be customized like a full-size truck on the road these days. It can tow over 12,000 pounds and is also available with a long list of fancy and safety features. There are some drawbacks with the Sierra, including a slightly sluggish base powertrain and outdated interior. But overall it is an attractive offer from the GMC in a very competitive class.

2018 GMC Sierra 1500 Interior Photos


To be honest, the 2018 GMC Sierra 1500 cabin is not that special when compared to Ram 1500 or Ford F-150. Higher trim levels are certainly luxurious, but overall, the Sierra 1500 is more focused on functionality. At the same time, material interiors and build quality are much better, especially on lower trims. There are also many bin and storage areas, and the center console in Sierras five passenger offers USB ports to keep your device connected and charged.

Comfort and space compete in the 2018 GMC Sierra 1500 three cab. The rear seats in the crew cabin are not as friendly as those offered by Ford or Ram, but families will still find plenty of space there. Flipping the rear seat opens a flat load floor.

The IntelliLink infotainment interface handles various audio, navigation and phone functions, and deserves praise for clear intuitive controls. It’s getting better since its upgraded processing speed and the addition of Android Auto and Apple CarPlay make calling up playlists, podcasts, contacts and certain apps much easier.
