This represents the first major update to the Acadia in quite a while. This was the first crossover to be introduced on the platform that's shared with the Enclave and Traverse, so it makes sense that it's the first to get refreshed. The new styling is the most notable difference, with a new three-bar grille and standard LED running lamps. If that grille looks familiar, it's because GMC showed something similar on the Sierra All-Terrain HD truck concept first seen at the 2011 Detroit auto show. While the Acadia nose is a toned-down version of that concept truck's front end, it still gives the 2013 crossover a much more upright, flat-nosed look. While it's an interesting choice here, it is a nose that's better suited to a pickup, which is where we expect it to go next. There are also updated taillights to match the changes up front, plus there's a new rear spoiler, new wheels, and now the rear uses wraparound rear glass.

Power still comes from a 3.6-liter V-6 with 288 horsepower, and the front-drive crossover has all-wheel drive as an option. The transmission is the next-gen Hydra-Matic 6T70 six-speed automatic, said to have better shift response. According to GMC, the suspension has been retuned as well. The same versatility in the cabin—including the SmartSlide second row, fold-flat third row, eight-passenger seating (now with more comfortable seats), and a cargo area that's wide enough to carry 48-inch-wide drywall—are back for 2013. It also comes with the industry-first front center airbag, which protects the passenger who is on the opposite side of the vehicle from where a collision happened.

The second vehicle GMC unveiled was a member of the Acadia family: the 2013 Acadia Denali. This trim level currently brings in 30 percent of Acadia sales, and GMC expects that percentage to go up. The Denali has different styling cues, with a three-section polished honeycomb grille, unique wheels, and a different color scheme in the cabin. It uses the same engine as the regular Acadia, but the Denali has more features that come standard. Pricing has not yet been released for either vehicle, and both will go on sale in late 2012.
