Mazda CX-90 配備 KPC（Kinetic Posture Control）車身平衡控制輔助系統。每當拐彎橫向力度超過 0.3g 數值，系統便會對彎內側車輪施加制動力，有效抑制呢部大型 SUV 過彎時可能出現嘅車身傾側，保持行車平穩舒適。
The Mazda CX-90 features KPC (Kinetic Posture Control). When cornering forces exceed 0.3g, the system applies braking force to the inside rear wheel, effectively suppressing body roll for a smooth and stable ride.
