The RS sport suspension plus with Dynamic Ride Control (DRC) is available as an performance-oriented alternative. This positions the body of the RS 7 Sportback another 4 millimeters (0.2 in) lower than the RS sport air suspension.
Dynamic Ride Control offers integrated pitch and roll stabilization consisting of steel springs and three-way adjustable dampers that counteract the movements of the vehicle body with no delay, without the use of electronics. When the vehicle is turning into and traveling round a bend, the damper response is altered so that the vehicle’s movements about the longitudinal axis (roll) and about the transverse axis (pitch) are significantly reduced.
The dampers on one side of the vehicle are connected to the dampers diagonally opposite to them via two separate oil lines, each of which has a central valve. The valves provide the necessary compensating volume via internal pistons with the gas-filled compartment behind them. When the vehicle is steering into and traveling round a bend, an oil flow is generated between the diagonally opposite dampers via the central valve, thus creating additional damping force.
When one side is cushioned, the damping characteristics are altered such that roll and pitch movements are eliminated almost entirely. As a result, this highly responsive damper system ensures that the high-performance coupé has particularly good track stability when negotiating bends.
