New Sport Chassis
To compliment the Volvo C30's new dynamic style, an optional Sports chassis will be available which gives the C30 a significantly sharper ride. The introduction of the Sports chassis means the car is lowered by 10 millimeters, resulting in a lower centre of gravity enhancing the driving characteristics. The steering is more precise owing to the installation of stiffer bushings. The steering ratio is lower, giving a 10 percent faster response to steering wheel input. Spring stiffness has been increased by 30 percent to deliver a more dynamic ride. The dampers too are stiffer and are designed to build up pressure more quickly. The roll stabilizers are also stiffer to reduce any leaning tendency when cornering. The new sport chassis is available as an option in all C30 variants except with the 1.6D DRIVe with Start/Stop. (More information on the new Sport chassis to follow).
