Ferrari 575M Maranello Suspension
Unsprung weight of the 575M Maranello has been safely lightened yet further, to provide exact steering and perfect control of the car in all conditions, especially in those necessitating excellent overall dynamic balance. One of the major factors on the car’s road-holding is the new adaptive set-up, based on a system of independently controlled damping at all four corners of the car. The system selects the ideal ride height for any condition, with two choices: Sport, which is selected for a more sporting ride, improving traction, and Comfort, which gives a more comfortable ride, absorbing road bumps. The 575M has four wheel independent suspension with a transverse parallelogram structure and triangular arms, aluminum gas dampers with coaxial coil springs, and anti-roll bars front and rear.
Brakes:
A car's performance is determined not only by its acceleration and stability but also by the quality of its deceleration. Ferrari has further modified the braking system of the 575M Maranello with Brembo, applying methods from Formula 1 to the 4-piston calipers on 13" front and 12.2" rear rotors. To cope with the increased performance of the vehicle, especially in terms of avoiding fade and improving response under braking, changes have centred on improving cooling for the brakes with new pad material (Ferodo HP1000;) reduction in brake pedal effort and an increase in the level of assistance from the servo system. The ABS/ASR system has been uprated from version 5.0 to 5.3.
ASR:
As with the rest of the Ferrari range, the electronic traction control of the 575M can be set between normal and Sport. The new Maranello offers a unique driver-adjustable dynamic stability control system. Depending on the selected mode, the system intervenes by cutting off the torque delivered by the engine, or, coordinated by the ABS system, braking the two rear wheels independently. It is the first driver-controlled active anti-wheel spin system. The mode selection complements the suspension damping setting, giving the driver total control of the car's lateral and longitudinal dynamics.
Steering:
The ZF speed-sensitive rack and pinion steering system varies assistance in relation to speed.
Wheels:
The unsprung weight has been optimised in the following way: the ABS/ASR sensors are integrated into the wheel bearings and the weight of the tires and rims has been reduced. These changes have seen the weight of the complete front wheel come down by 4lbs and that of the rear by 2.6lbs. The tires have also evolved and now produce less noise, are longer lasting and perform better in aquaplaning conditions. A new optional tire, suitable for more extreme performance with improved lateral and longitudinal grip, has now been produced in a 19 inch size measuring 305/30 ZR19 at the rear and 255/35 ZR19 at the front respectively. The 575M Maranello is also fitted with tire pressure sensors, which mean that tyre pressures can be checked while the car is on the move, and even when the engine is off.
