This engine is rated at 250 hp if you use premium fuel, but there's no reason to do so; it puts out plenty of power on regular. We got an impressive 22 mpg overall. Mazda's flagship SUV has nimble handling that makes it feel like a smaller vehicle. The ride is very comfortable, and the cabin is commendably quiet. The interior is well-finished, particularly on high-end trims, and features comfortable seats, but the cockpit is snug and power-seat adjustments are limited. Mazda's dial-controlled infotainment system takes time to master. All but the base trim come with blind spot monitoring. Available safety features include automatic emergency braking and forward collision warning.

Based on a stretched version of the platform of the Ford Edge, the Mazda is quieter, more agile, and has a nicer interior with attractive trim. The third-row seat is small but relatively easy to access. Handling is taut and agile, plus the ride is firm and steady, yet comfortable. Braking distances are a bit long though. The 60/40-split second-row seats slide fore and aft for greater second- or third-row legroom. The CX-9 initially used Ford's punchy, 3.5-liter V6 engine, but it got a smoother, more refined 3.7-liter V6 in 2008. Neither engine is particularly fuel-efficient. The optional blind-spot warning system works well, but the CX-9 performed poorly when tested in the IIHS small-overlap crash test. The CX-9 soldered on for many years without a redesign, making later model years feel comparatively dated next to the competition.
