By now, Mazda's turbocharged 3.3-liter inline-six engine shouldn't be a surprise. Debuting last year with the CX-60 offered in markets outside the US, it's the range-topping mill for the CX-90. However, it's considerably more powerful here, developing 340 hp and 369 pound-feet of torque sent to all four wheels. That's not pure combustion power, however, as Mazda nestles a small electric motor between the engine and transmission in a mild hybrid setup.
For those seeking a broader application of electric power, the second option is Mazda's PHEV e-Skyactiv powertrain. A 2.5-liter four-cylinder works with an electric motor to generate a combined 323 hp and 369 lb-ft of twist, once again going to all four wheels. A 17.8 kWh battery feeds the motor, giving the CX-90 the capability for longer electric-only travel. If this all sounds familiar, it's the same setup offered in the CX-60 and as such, the CX-90 likely has a similar all-electric range of around 39 miles. Note we said likely – Mazda hasn't yet announced official CX-90 range figures.
Regardless of the engine, two things always remain the same. AWD is standard, and power reaches the ground through a new eight-speed automatic transmission that ditches the old-school torque converter. With electrification, Mazda says power delivery with this transmission is smooth and direct while also improving efficiency. We'll have to take Mazda's word on that last bit, as mileage stats aren't yet available. Similarly, the automaker isn't ready to share figures for acceleration or top speed.
Mazda equips the big SUV with Kinematic Posture Control, which debuted on the 2022 Miata to give the sports car better poise and feel in corners. The system applies slight brake pressure to the inside rear wheel during cornering, and according to Mazda, it helps suppress body roll while giving a liner feel to the CX-90's steering.
A 12.3-inch center infotainment screen sits atop the dash, complemented with an array of tactile controls for operating common-use features like seats and climate control. Another digital display is available for the driver, and depending on the options chosen, features like third-row air conditioning and USB-C charging ports are available.
