The MDX SH - AWD ® rear drive unit is constantly overdriven by 1.7 - percent and the resulting overdrive effect is regulated by left - and right - side electromagnetic clutch packs within the rear differential that independently control the power delivered to each rear wheel. (topspeed.com)
The SH - AWD ® ECU also monitors steering angle, lateral G - forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts. (topspeed.com)
Direct electromagnetic clutch systems mounted on either side of the hypoid gear that drives the rear axle control the amount of torque sent to each rear wheel and provide a limited - slip differential function when needed. (topspeed.com)
