The 2018 GMC lineup promises to impress. With a host of new technologies and a number of significant design changes, the 2018 lineup is setting new standards in the industry. At Knight Automotive, we’ve compiled a list of the new features for the latest lineup, including a breakdown of ways some of your favorite cars are being updated.


According to Car and Driver, the 2018 Terrain will have multiple changes. For example, the exterior design is noticeably leaner and more aggressive, with a shorter wheelbase and length. There’s also now a turbocharged engine under the hood, and an optional 1.6-liter diesel engine will be offered as well. The gas engine also gets a nine-speed automatic transmission, allowing for a truly smooth ride.


The Yukon and Yukon XL are adding the latest 10-speed automatic transmission, a tuned powertrain feature that’s great for city and highway. This SUV will also get a new grille, interior wood trim options, and a few minor trim changes.

Minor Changes

The Acadia and Sierra HD will have minor trim changes, while the Canyon and Sierra 1500 will carry over many of the great qualities from the previous model year. The Savana—GMC’s long-running full-size van—is also getting some changes. These include a new 4.3-liter V6 engine, an optional 2.8-liter turbo-diesel, and an eight-speed transmission. These exciting changes truly set the new 2018 GMC lineup apart.
