Mazda's CX-9 is a stylish three-row SUV that is quite engaging to drive. Power comes from a responsive, free-revving 227-hp, 2.5-liter turbo four-cylinder mated to a smooth six-speed automatic. This engine is rated at 250 hp if you use premium fuel, but there's no reason to do so. We got 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. Available safety features include automatic emergency braking and blind-spot monitoring.
