When does the 2025 QX55's Active Trace Control apply brake pressure?

The Active Trace Control system in the 2025 QX55 is designed to enhance vehicle stability and handling during various driving conditions, particularly when cornering. This system monitors the vehicle's dynamics and can apply brake pressure to specific wheels to help maintain optimal traction and control. During cornering, as the vehicle shifts weight and the dynamics change, the Active Trace Control can intervene by adjusting brake pressure on the outside wheels. This action helps to counteract understeer or oversteer, allowing for a smoother and more controlled cornering experience.

The other scenarios do not leverage the specific enhancements that Active Trace Control offers. For example, heavy braking generally involves the vehicle’s main brake system rather than adjustments made for cornering dynamics. Reversing and driving on straight roads do not typically require the same level of dynamic response, as there is minimal lateral movement or weight transfer involved. Therefore, cornering is where the technology is most applicable, cementing its role in improving driving performance in those situations.
