Lexus Raises Handling and Performance with Provision of Adaptive Variable Suspension for RC F and GS F Models

The Lexus “F” designation is used to signal excellence in both performance and handling. To ensure that the 5.0-litre V8-powered RC F coupe and GS F saloon are faithful to their special status within Lexus’s model range, both are now equipped with Adaptive Variable Suspension as standard.

This is not simply a matter of introducing a stock system into the cars. The technology has been revised, tuned and integrated with precision so that its maximum potential can be realised.

The driver-selectable, electronic AVS monitors and controls the damping force at each wheel, adjusting instantaneously to ensure handling stability and ride comfort according to road conditions and the driver’s preferences. The system uses an array of sensors which constantly monitor parameters such as G-forces, yaw rate and vehicle speed. Based on this data, the AVS can adjust the level of damping force through 30 levels, ensuring optimum control on all road surfaces. This marks a significant refinement in operation compared to Lexus’s previous system, which spanned nine operating levels.

When cornering, the AVS applies increased damping force in response to steering input, yaw rate and vehicle attitude to provide pinpoint handling and suppress body roll through the turn. On rough surfaces, damping force is reduced to help absorb vibrations and keep the ride smooth and comfortable. In all, the system has seven damping force control strategies that include anti-dive and anti-squat. It also works to keep the car composed under heavy braking and acceleration.

Going further than simply increasing suspension control, the AVS has been linked to the cars’ Vehicle Dynamics Integrated Management (VDIM) and Drive Mode Select control. The instrument display has been revised to show when the driver has selected Sports AVS.
