The Mazda CX-9 and CX-7 are equipped with Mazda’s new active torque split all-wheel drive system. The all-wheel-drive system achieves a fine balance between sporty control and handling stability on snowy or wet surfaces, or under other challenging road conditions, that makes it particularly enjoyable to drive. Power and torque are effectively transferred to the road surface for maximum efficiency and performance.
The system uses real-time input data on steering angle, yaw rate, lateral G force and engine status to determine road surface and driving conditions. The active torque coupling mounted in front of the rear differential is electronically controlled accordingly, adjusting front/rear wheel torque distribution between 100:0 and 50:50 to deliver optimum drive power to each wheel. The result is powerful acceleration and positive handling regardless of constantly changing road conditions, as well as the ability to fully balance the car in a turn by deft use of the accelerator pedal.
The Mazda CX-9 and CX-7’s onboard computer automatically determines driving and road conditions so the driver can relax and enjoy the pleasure of the drive.
A new rear differential with greater torque capacity is employed by the system to deliver a high level of reliability. Increased torsional rigidity of the propeller shaft and rear differential mount improves the response of torque transfer to the rear wheels and delivers a more rigid feel to the ride under acceleration. A limited slip differential is used in the rear to optimise transfer of torque to the left and right rear wheels, bringing solid traction and linear vehicle control for a stable-feeling ride when cornering.
