2018 GMC Acadia: What's Changed

2018 GMC Acadia


  • Most significant changes: A tire-fill alert that monitors how much air is pumped into an underinflated tire is now standard. The All Terrain Package is now available with seating for five, six or seven people.
  • Price change: The starting prices for the SL and Denali models are $50 lower, but a destination charge that's $50 higher for all versions leaves the price of these trims effectively unchanged. All other models are $160 higher, including destination.
  • On sale: Now
  • Which should you buy, 2017 or 2018? The 2017. There are no groundbreaking changes for 2018, and dealers should be willing to discount the remaining 2017 models.

The GMC Acadia SUV was redesigned for the 2017 model year with smaller dimensions and updated-but-familiar styling. Instead of coming only with three rows of seats and a V-6 engine like its predecessor, the redesigned Acadia offered two- and three-row versions and four-cylinder or V-6 power.

Among few changes for 2018, the tire pressure monitoring system adds a fill alert that monitors how much air is pumped into a tire to prevent overfilling, and Denali models get a standard automatic heated steering wheel. The All Terrain Package for SLE and SLT trim levels is available with five, six or seven seats; it came only with five seats in 2017.

The 2018 Acadia's base engine is a 193-horsepower, 2.5-liter four-cylinder; a 310-hp, 3.6-liter V-6 is optional. Front- and all-wheel-drive versions are offered.

Even though it's smaller than before, the Acadia retains much of the utility and practicality of the previous version while offering greater agility and fuel efficiency.
