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; 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. Updates for 2018 included standard forward collision warning, automatic emergency braking, and blind spot warning. Apple CarPlay and Android Auto capabilities were added to the infotainment system for 2019. Slight suspension tweaks and noise reduction measures were also new. For 2020, captain's chairs in the second row are optional on Touring and Grand Touring. Pedestrian detection is standard. Updates for 2021 included a new infotainment system, but we found it more difficult to use. All-wheel drive is standard for 2022. 2023 is the final year for the CX-9 replaced by the CX-90.
