2027 GMC Acadia Engine, Price, Dimensions – The 2027 GMC Acadia arrives with a full-scale redesign that moves the model into a more commanding and premium space. It’s no longer a midsize SUV trying to stay compact—it’s grown in every dimension to better compete with three-row rivals like the Ford Explorer and Toyota Highlander. With an extended wheelbase and more muscular frame, the Acadia now sits firmly in the large SUV category while retaining its nimbleness. 2027 GMC Acadia Engine
2027 GMC Acadia Redesign and Update Plan
Exterior & Interior
The 2027 Acadia commands attention with a bolder grille, squared-off LED headlights, and a more vertical front fascia. It borrows design inspiration from GMC’s Sierra and Yukon models, incorporating C-shaped LED running lights, a wide stance, and muscular wheel arches. New color options like Redwood Metallic and Arctic Frost give the SUV fresh character, while trims like AT4 and Denali now come with exclusive styling treatments including skid plates, chrome delete packages, and adaptive air suspension for improved ride height control.
Around the back, the updated Acadia features full-width LED taillights and a redesigned tailgate that improves loading ease. Roof rails, new 20- to 22-inch wheel options, and more defined body sculpting contribute to its premium look. The AT4 variant gains an off-road oriented fascia, increased ground clearance, and a two-tone appearance with functional red tow hooks. All trims benefit from an improved drag coefficient thanks to subtle aero enhancements.
Step inside, and the 2027 Acadia feels worlds apart from its predecessor. GMC has prioritized upscale materials, with available open-pore wood, brushed aluminum, and quilted leather trim. A massive 15-inch portrait-oriented infotainment display dominates the dash in most trims, complemented by an 11-inch digital gauge cluster. Ambient lighting, tri-zone climate control, and upgraded sound insulation make for a more refined experience. A new second-row sliding seat design improves third-row accessibility, and cargo volume now tops 80 cubic feet with the seats down.
This new generation rides on GM’s updated C1 platform, allowing for improved rigidity, better suspension geometry, and enhanced ride comfort. The exterior proportions are now boxier and more upright, a deliberate departure from the rounded aesthetic of the outgoing model. With added width and height, it boasts increased cabin space and cargo capacity. The redesign focuses on enhancing utility without compromising on GMC’s upmarket styling cues.
From a technological standpoint, the 2027 model ushers in a full refresh across lighting, infotainment, and safety systems. It also debuts a new architecture that supports over-the-air (OTA) software updates, GM’s Ultra Cruise semi-autonomous driving system (in select trims), and a more streamlined interface for connected services. This isn’t just a facelift—it’s a platform-wide reimagining of what the Acadia name stands for.
2027 GMC Acadia Specs
Engine & Performance
Under the hood, the 2027 Acadia drops the old naturally aspirated V6 in favor of GM’s latest 2.5-liter turbocharged four-cylinder engine. But don’t let the downsizing fool you—this unit churns out an impressive 328 horsepower and 326 lb-ft of torque, easily outpacing the previous V6 in both performance and efficiency. It’s mated to an advanced 8-speed automatic transmission with smoother shift mapping and quicker downshifts.
All-wheel drive is available across the range, and standard on AT4 and Denali trims. The AT4 gains hill descent control, a terrain-select system, and electronic twin-clutch rear differentials for off-road capability. Towing capacity has increased to 5,500 pounds, making the 2027 Acadia a true weekend adventure vehicle. The ride quality benefits from updated suspension with adaptive dampers, and an optional air suspension further elevates handling comfort, especially when fully loaded.
Denali buyers receive a fine-tuned version of the same powertrain but with improved insulation, smoother calibration, and performance suspension. The steering has been reweighted for better on-road precision, and driving dynamics are now among the best in the segment. Whether navigating tight urban streets or cruising at highway speeds, the Acadia feels responsive and planted, reflecting GMC’s continued investment in chassis tuning and ride dynamics. 2027 GMC Acadia Engine
2027 GMC Acadia Fuel Economy
The 2027 Acadia performs admirably in fuel efficiency despite its larger size and improved power. Thanks to its lighter construction, start-stop system, and turbocharged engine, it achieves an EPA-estimated 23 mpg city and 29 mpg highway for front-wheel-drive models. AWD trims see a modest drop, with figures around 21 mpg city and 27 mpg highway—still competitive within the segment.
2027 GMC Acadia Safety Features
GMC pushes safety to the forefront in the 2027 Acadia with a comprehensive suite of standard and available driver-assistance technologies. Every trim level comes equipped with GMC Pro Safety Plus, which includes automatic emergency braking, forward collision alert, front pedestrian braking, lane keep assist with lane departure warning, and IntelliBeam automatic high beams. These systems have been updated with better sensor accuracy and quicker response times.
Advanced safety features such as rear pedestrian alert, adaptive cruise control with stop-and-go, and lane centering assist are available on mid and upper trims. The new Surround Vision camera system offers 360-degree visibility, enhanced by high-resolution cameras placed at each corner. Rear Cross Traffic Braking and Traffic Sign Recognition are also available, adding another layer of protection in daily driving and on longer trips.
One of the biggest leaps is the introduction of Ultra Cruise on Denali trims. This semi-autonomous driving system builds on Super Cruise but offers enhanced lane changing, automatic overtaking, and broader map coverage across U.S. highways. Combined with a driver-facing camera for attentiveness, it offers hands-free driving on over 400,000 miles of mapped roads. With this level of automation and awareness, the 2027 Acadia brings near-luxury class safety into the mainstream three-row SUV market. 2027 GMC Acadia Engine
