The secret is in the three discreet buttons on the dashboard, labelled Comfort, Sport and Advanced Sport.
At the push of a button, the driver indicates how he wants to drive his S60R. The intermediate setting, "Sport", provides optimum performance during normal but sporty driving. Starting from this point, the driver also has the choice of two outer settings. The "Comfort" setting uses "Sky Hook" technology to optimise the body's insulation against an uneven road surface. It is as if the car was suspended from virtual shock absorbers in the sky. The "Advanced sport" setting transforms the Volvo S60R into an uncompromising sports car which prioritises maximum driving pleasure and direct road contact.
What gives the driver this freedom of choice is the unique Four-C Technology, the Continuously Controlled Chassis Concept. It is the Four-C Technology's ability to collect large amounts of information on the movement of the car, and adjust the dampening of the shock absorbers extremely quickly, which makes the chassis on the Volvo S60R one of the most advanced on the market.
The system then very rapidly adjusts the damping on the shock absorbers and the electronic control of the AWD system.
Every other millisecond, i.e. 500 times per second, Four-C updates the setting on each shock absorber, on the basis of continuous information on the car's speed, the movement of the wheels and chassis, and the position of the steering wheel.
