Mazda’s proprietary system is called Kinematic Posture Control, or “KPC” for short. This system works somewhat similarly to the concept of torque vectoring, which distributes a car’s torque to its wheels to maintain control. However, KPC is a little more advanced than that, focusing not only on the strength of the wheels, but the posture of the entire vehicle.
Through a network of sensors working in tandem with the car’s onboard braking and suspension systems, the KPC framework automatically detects when one side of the vehicle is experiencing higher levels of G-force than the others, like when it’s skidding. When the sensors kick in, braking force is automatically applied to the inner section of the relevant rear wheel. Not only does this help to increase the wheel’s traction on the ground, but it also forces the car downward, reducing the chances of it going off the ground or flipping over. Braking force can also be applied in varying degrees, such as when you drive through a tight corner and put more pressure on one side of the car. KPC keeps you leveled out and reduces strain on the car’s suspension as it takes the turn.
