Limited Slip Differential

Limited Slip Differential







The advantages in terms of driving dynamics are boosted once again by the electronically controlled rear-axle differential lock with variable locking effect. The rear-axle differential lock improves traction if required during extreme lateral acceleration, when accelerating on surfaces with varying levels of grip and when accelerating out of tight bends. Electronic braking intervention (ABD) for traction control is used less frequently.

During load changes in a bend, the vehicle turns in less and remains more in line as a result of the yawing moment produced by the rear-axle differential lock. Any turn-in response triggered by abrupt deceleration is significantly reduced. Extreme acceleration can make the vehicle oversteer, e.g. on race circuits, which experienced drivers find easier to control. On the all-wheel-drive models, the rear-axle differential lock supports the driving dynamics of the controlled all-wheel system, Porsche Traction Management (PTM).
