2021 GMC Acadia Denali AWD Automatic

Model Highlights

The GMC Acadia comes with a choice of three different engines--a fuel efficient 2.5L 4-cylinder making 193 horsepower, a 3.6L V6 with 310 horsepower and a 2.0L turbocharged 4-cylinder making 230 horsepower. Engines send power to either the front wheels or to all four wheels via a 9-speed automatic transmission. Even the all-wheel drive Acadia with the V6 manages 26 mpg on the highway, while 4-cylinder versions do remarkably well with a 21 mpg city rating for front drive versions with either 4-cylinder engine. The GMC Acadia comes in SL, SLE, SLT, AT4 and top-of-the-line Denali trims. The base SL model has plenty of features, despite its low base price. Key amenities include keyless open and start, tri-zone climate control, an 8-inch touch radio with IntelliLink, Apple CarPlay, Android Auto, Bluetooth, five USB ports, a rearview camera and 4G WiFi technology, meaning that buyers can turn their Acadia into a mobile WiFi hotspot. The base Acadia also comes with 17-inch aluminum wheels, LED headlights and daytime running lights as well as heated mirrors. Key features included on the SLE include a SiriusXM satellite radio, a programmable power liftgate, power adjustable driver's seat, 18-inch aluminum wheels, blind spot detection system, a rear cross-traffic alert system and rear parking sensors. SLT models add perforated heated leather front seats, auto-dimming mirrors both inside and outside, a remote starter, and a parking assist system. Standard safety features include Lane Keep Assist, Automatic Emergency braking, Front Pedestrian Braking, Following Distance Indicator, front/rear parking sensors and Teen Driver mode. The new AT4 Acadia is built for a bit more capability in low grip conditions. The AT4 comes with a beefier all-wheel drive system, all terrain tires, 17-inch gloss black wheels, a traction control system with an off-road mode and more weather resistant floor mats. The AT4 also comes standard with the V6 engine. Top-of-the-line Denali models stand out with their unique signature Denali grille and 20-inch polished aluminum wheels. Front seats come heated and ventilated on the Denali, while the steering wheel also gets a heating function--essential for those really cold days. The Denali versions also get a power tilt and telescoping steering wheel, heated second-row seats and upgraded interior trim.
