What Changed in the 2018 GMC Acadia?

The 2018 model year brought subtle but meaningful enhancements to GMC's popular Acadia SUV. Following its complete 2017 redesign, the updates focused on convenience features and package flexibility rather than major mechanical changes.

Notable Standard Features

  • Tire-Fill Alert System: This innovative feature monitors air pressure during inflation, alerting drivers when optimal tire pressure is reached
  • Expanded All Terrain Package: Now available with 5, 6, or 7-passenger configurations (previously only 5-seat)
  • Denali Upgrades: Heated steering wheel became standard on the premium Denali trim

Powertrain & Performance Specifications

Engine Option Horsepower Torque EPA Combined MPG
2.5L 4-cylinder (standard) 193 hp 188 lb-ft 22 mpg
3.6L V6 (optional) 310 hp 271 lb-ft 20 mpg

The Acadia's smaller footprint compared to previous generations contributed to improved handling and fuel efficiency without sacrificing cargo capacity.
