2026 GMC Acadia vs 2026 Mazda CX-90
Comparison Overview
The 2026 GMC Acadia charges onto the scene with a brawny 328 hp engine, promising robust capability in its massive 204.0-inch frame. In contrast, the 2026 Mazda CX-90 tantalizes with superior efficiency and standard All-Wheel Drive, despite packing 48 fewer horsepower, logging a commendable 25 MPG combined. The Acadia boasts significantly more room, offering 23 cu ft of cargo space versus the CX-90’s 14.9 cu ft, a crucial factor for larger families. However, the CX-90 undercuts the GMC substantially on price, starting at just $38,800 compared to the Acadia’s $43,700 MSRP. While the Acadia’s power advantage is clear, the CX-90 counters with better fuel economy (28 highway MPG vs. 27 highway MPG) and superior torque delivery (332 lb-ft vs. 326 lb-ft) for a potentially snappier feel off the line, making this a true battle of brute force versus refined efficiency.
