Ferrari Suspension Light

The Ferrari Luce's suspension is one of the focal points of the project, as it works together with the electric motors, steering, regeneration and control software. The car uses four electrically actuated active suspensions, derived from the experience of the Purosangue and F80 and evolved to take advantage of the greater freedom offered by the electric architecture. Each wheel is managed on several levels. There is one actuator for traction and regeneration, one for steering angle and one for vertical movement. In practice, the dynamics of the car do not depend solely on the rotation of the steering wheel or the torque sent to the motors, but on continuous coordination between torque vectoring, set-up, footprint and wheel response. The front suspension is semi-virtual and uses the split lower arm to position the virtual steering axis close to the wheel centre. This reduces steering sensitivity to bumps and torque peaks transmitted to the wheels, smoothes reactions during braking and keeps ground contact cleaner. The steering ratio is 13 per cent more direct than in previous applications, which supports the car's agility without making corner entry sharp. The active dampers use an internal recirculating ball screw. The 20 per cent increased wheelbase improves the ability to absorb and control vertical impacts, reducing the inertial force transmitted to the chassis in the wheel strike. The shock absorbers weigh 2 kilograms less than previous applications and incorporate a thermocouple to monitor oil temperature and normalise cold response. Suspension is not just for comfort and handling. They also contribute to aerodynamic efficiency by lowering the car 10 millimetres at the front when it is convenient. They can also recover energy by exploiting the relative motion between the wheel and chassis. The system works in conjunction with the independent steered rear wheels, Virtual Short Wheelbase 3.0, ABS Evo and Side Slip Control X. Noise and vibration reduction also goes through here. The first elasticised subframe in Maranello's history, the modelling between the chassis, subframe and underfloor battery and the mass damper integrated into the steering wheel are elements designed to filter out vibrations without taking away precision.
