If you’re shopping for a new three-row SUV near McKinney, Allen, or Frisco, this detailed comparison will help you decide whether the Mazda CX-90 or GMC Acadia best matches your lifestyle and priorities.

Power, Performance, and Efficiency

Both SUVs come with impressive powertrains — but the way they deliver performance differs.

Mazda CX-90 Performance

The 2026 Mazda CX-90 is built on Mazda’s new longitudinal platform, designed to prioritize balance and driving feel. It’s powered by a 3.3-liter inline-6 turbocharged engine, supported by Mazda’s M-Hybrid Boost 48-volt system, creating a smooth and responsive performance profile.

• Standard Output: 280 hp / 332 lb-ft torque (on regular fuel)

• High-Output Version: Up to 319–340 hp / 369 lb-ft torque (on premium fuel)

• Transmission: 8-speed automatic

• Drivetrain: Standard i-Activ AWD

• Fuel Economy: Approx. 23 city / 28 highway / 25 combined mpg

• Towing Capacity: Up to 5,000 lbs

Mazda also offers the CX-90 Plug-In Hybrid (PHEV) model, combining a 2.5-liter four-cylinder engine with an electric motor and battery system to provide both power and efficiency. The PHEV variant can travel short distances on electric power alone — perfect for city commuting or low-emission driving days.

GMC Acadia Performance

The redesigned 2026 GMC Acadia introduces a new turbocharged 2.5-liter four-cylinder engine paired with an 8-speed automatic transmission.

• Power Output: 328 hp / 326 lb-ft torque

• Drivetrain: FWD standard, AWD optional

• Towing Capacity: Up to 5,000 lbs

• Estimated Fuel Economy: Around 20 city / 26 highway mpg

The Acadia’s performance leans toward capable and confident rather than sporty. It delivers solid acceleration and steady power delivery, with available trailering packages that make light towing easy for weekend adventures.

Verdict:

The CX-90 feels more refined and performance-oriented, thanks to its inline-6 architecture and hybrid boost system. The Acadia offers dependable strength and good numbers, but Mazda’s focus on precision handling and fuel efficiency gives it an edge for drivers who enjoy being behind the wheel.

Interior Comfort and Cabin Experience

Mazda CX-90 Interior

Inside, Mazda takes a premium-first approach. The CX-90’s cabin blends soft materials, elegant Japanese design cues, and intuitive technology placement. Higher trims include Nappa leather upholstery, real wood accents, and available second-row captain’s chairs.

• Passenger Capacity: Up to 8 passengers

• Cargo Space: ~14.9 cu ft behind 3rd row; over 74 cu ft with both rear rows folded

• Infotainment: 12.3-inch center display with Mazda Connect, wireless Apple CarPlay® and Android Auto™

• Sound System: Optional 12-speaker Bose® premium audio

• Climate Control: Tri-zone automatic

Mazda’s craftsmanship shows in the details — precise stitching, chrome accents, and driver-centric ergonomics make it feel more like a luxury SUV than a family hauler.

GMC Acadia Interior

The 2026 Acadia emphasizes space and technology. It offers an expanded interior over the previous generation, with a sleek new design and a tech-focused dashboard.

• Passenger Capacity: Up to 8 passengers

• Cargo Space: 23.0 cu ft behind 3rd row; 97.5 cu ft maximum (estimated)

• Infotainment: 15-inch vertical touchscreen with Google Built-In

• Digital Cluster: 11-inch driver display

• Climate Control: Tri-zone automatic

The Acadia’s large infotainment display and connected tech features are standout elements. The cabin design feels modern, if slightly more utilitarian compared to Mazda’s premium finishes.

Verdict:

The Acadia wins for sheer cargo room and screen size, making it a strong choice for families prioritizing space. The CX-90 edges ahead in craftsmanship and ambiance, offering a more refined and upscale driving environment.

• Automatic Emergency Braking

• IntelliBeam® auto high-beams

• Rear Cross-Traffic Braking

Higher trims, such as the Denali Ultimate, add adaptive cruise control, HD surround vision, and hands-free Super Cruise™ semi-autonomous driving technology (available on select models).

Technology, Infotainment, and Connectivity

Technology can make or break a modern SUV experience.

• Mazda CX-90: Features an intuitive rotary controller and clear 12.3-inch center display. Wireless smartphone mirroring, integrated navigation, and available head-up display enhance convenience without overwhelming the driver.

• GMC Acadia: Prioritizes screen size and connectivity, boasting a 15-inch touchscreen with Google Built-In, voice-activated functions, and over-the-air update capability.

Both vehicles support Wi-Fi hotspots, multiple USB ports, and Bluetooth® connectivity, ensuring passengers stay connected and entertained.

Pricing, Trims, and Ownership Value

The 2026 Mazda CX-90 lineup is expected to start around $39,000–$40,000 for base trims and climb to about $58,000+ for the top Signature PHEV model.

The 2026 GMC Acadia Elevation trim starts around $43,700, with Denali Ultimate models likely exceeding $55,000.

Ownership value depends on your priorities:

• Mazda CX-90 offers longer hybrid range options, strong fuel economy, and a premium feel without luxury-brand pricing.

• GMC Acadia offers slightly more space, easier family usability, and cutting-edge infotainment technology.

Mazda’s reputation for reliability and low maintenance costs often appeals to drivers looking for long-term ownership confidence.

Both SUVs offer remarkable capability and comfort, but each appeals to a different audience.

Choose the Mazda CX-90 if you want:

• A refined, performance-tuned drive

• Premium craftsmanship and materials

• Hybrid efficiency and strong torque

• Exceptional safety ratings

Choose the GMC Acadia if you prefer:

• Cutting-edge infotainment and driver-assist tech
