Detroit LIVE: 2017 GMC Acadia

The new Acadia is 700 pounds lighter than the outgoing model.

GMC has officially unveiled the 2017 Acadia at the 2016 Detroit Auto Show.

More refined than ever before, the Acadia is up to 700 pounds lighter than the outgoing model thanks in part to a body structure made with high-strength steel. More weight was shed by simply reducing the crossover's dimensions, and it's seven inches shorter and about three inches narrower than its predecessor. The more compact dimensions and the lighter weight help both driving dynamics and efficiency.

The Acadia lineup is divided into three models: the regular Acadia, the luxury-focused Acadia Denali, and the off-road-ready Acadia All Terrain. Range-topping Denali models gain a specific grille with a thick chrome frame, extra chrome trim on the lower bumper, large alloy wheels, and HID headlights. The All Terrain version receives a twin-clutch all-wheel drive system with an All Terrain mode, a body-colored grille, specific wheels, and black chrome trim all around.

Developed with families in mind, the Acadia offers a drawer integrated into the center console, USB ports for all three rows, and an innovative alert system that reminds the driver when an item may have been left in the second- or third-row seats. Trunk space checks in at 12.8 cubic feet with seven passengers on board. Folding down the third row yields 41.7 cubic feet, while up to 79 cubes are available with the second and third rows folded flat. The aforementioned All Terrain model is exclusively offered as a five-seater because it gets covered storage bins in lieu of a third row.

Confirming a recent rumor, the Acadia's standard engine is a 2.5-liter four-cylinder engine that delivers 195 horsepower at 6,300 rpm and 190 lb-ft. of torque at 4,400 rpm. For more power, buyers can step up to a 3.6-liter V6 tuned to generate 310 horsepower at 6,600 rpm and 271 lb-ft. of torque at 5,000 rpm. Front-wheel drive and a six-speed automatic transmission come standard, and all-wheel drive is offered at an extra cost. The Acadia can tow up to 4,000 pounds when properly configured.

Fitted with GMC's first-ever start/stop system, the four-cylinder returns a General Motors-estimated 22 mpg in the city and 28 mpg on the highway when it spins the front wheels. Selecting the six-cylinder lows gas mileage to 17 and 25 mpg, respectively. Official EPA figures won't be published until closer to the Acadia's launch date.

The 2017 GMC Acadia will go on sale this spring. Since the Acadia is getting replaced, it's safe to bet that new versions of the Chevrolet Traverse and the Buick Enclave are right around the corner.
