The 2017 GMC Acadia will arrive this spring 700 pounds lighter with new powertrains, additional safety technologies, and a Denali trim model, as it enters its second generation.

General Motors unveiled the 2017 Acadia at the North American International Auto Show in Detroit on Jan. 12.

The redesign should make the Acadia more attractive in the highly competitive mid-size SUV segment that also includes the Chevrolet Traverse and Buick Enclave that have shared GM's Lambda platform. The 2017 Acadia will no longer be built on this platform.

The Acadia will arrive as a smaller vehicle than the outgoing model. GMC has shaved off 7.4 inches from the wheelbase and 7.2 inches from the overall length. The three-row SUV will offer trim grades for five, six or seven passengers.

A revamped engine lineup will power the Acadia starting with a new 2.5L four-cylinder standard engine that makes 194 hp and 190 lb.-ft. of torque. A new available 3.6L V-6 engine increases power over the outgoing V-6 to 310 hp and 271 lb.-ft. of torque. Power is delivered through a 6-speed automatic transmission to standard front-wheel drive or available all-wheel drive.

GM will offer a new All Terrain model with an advanced all-wheel-drive system with an active twin clutch. This model provides greater hill-climbing capability.

Curb weight falls to 3,956 pounds for the front-wheel Acadia compared with 4,656 pounds for the outgoing model. The lighter weight should pay off at the gas pump. GM estimates the 2.5L FWD Acadia should reach 28 mpg on the highway and 22 mpg in the city. The 2017 Acadia will also be the first GMC vehicle to offer stop-start technology.

Available safety and convenience technologies include front pedestrian braking, low-speed forward braking, forward collision alert, lane keep assist, and front and rear parking assist.

The vehicle will offer a Denali trim with HID lamps, a dimensional chrome grille, and six-spoke wheels.
