Ferrari Luce Active Suspension System

With a lower center of gravity and reduced polar moment of inertia, the suspension needs lower active forces to balance cornering loads across all four wheels.

The main update concerns the ball screw connected to the electric engine, which is the true heart of the system. The screw has a 20% increased pitch and is able to better absorb and control vertical impacts, thanks to a reduced transfer of inertial force to the car’s chassis.

The electric engine is able to deliver the same torque as previous application and actively regulates the forces exchanged between the chassis, tires and the ground, without compromises between variable elastic setup and body motion control. The shock absorbers feature an optimized design that has lead to a weight reduction of 2 kg, and integrate a thermocouple dedicated to monitoring the temperature of the lubrication oil, with the aim of normalizing behavior in both hot and cold conditions. Unlike previous projects, the suspension button is no longer installed on the Manettino, thus making it possible to separate the ride comfort setting from the other control systems. The active suspensions contribute to providing the four-wheel modules with independent control freedom of the vertical forces. The configuration of electric powertrain with four engines, combined with the presence of four-wheel steering, makes this car the first Ferrari to have active actuators capable of controlling vertical, longitudinal and lateral forces in all dynamic conditions, thus guaranteeing the Driving Thrills typical of Prancing Horse cars.
