Ferrari 458 Italia Suspension, SCM and Tires
The Ferrari 458 Italia has an innovative new suspension architecture compared to the F430: the front wishbones have L shape arms while there is a multilink suspension to the rear. This innovative approach results in greater longitudinal flexibility, which improves the car’s ability to absorb bumps, reduces suspension noise, boosts transverse rigidity and consequently improve 458 Italia’s handling and responsiveness.
These characteristics combined with specific tire development further improve overall vertical rigidity for less body roll and allow the introduction of a more direct steering ratio (11.9 degrees compared to the 16.9 of the F430, resulting in a 30 percent improvement). Quicker and more responsive steering consequently provides higher safety on both road and track driving experiences. The car new suspensions also offer a better compromise between vibrational and acoustic comfort as well as sportiness.
The Magnetorheological Suspension control (SCM) was first introduced in the Ferrari 599 GTB Fiorano and uses a fluid which viscosity instantaneously reacts to an electronically controlled magnetic field generated inside the damper. The control software adjusts the intensity of the magnetic field every millisecond, for an improved calibration and responsiveness on uneven ground. Compared to the previous version, …
