Ferrari 575M Maranello
The key elements of the Ferrari 575M Maranello can be neatly summed up in the model name. In fact, the engine is described by the new numerical code, 575, as this is an abbreviated indication of its capacity, increased from 5500 to 5750 cc, resulting in an increase in both power and torque. The letter M, an abbreviation of "modified," underlines the fact that changes have been wrought to all areas of the model's performance. Key amongst these, apart from the engine is the introduction of an F1 type gearbox, first time on a 12 cylinder Ferrari road car.
When it came to looking at the style of the vehicle, the thinking behind it is to retain the balance and sober looks, which invested it with the status of an instant classic, fitting in perfectly with Ferrari's return to a front engine high performance car. Modifications were limited to those required to deal with the technical changes: different shape and size for the air intakes in the new front end of the car, with refinement of the aerodynamic and fluid-dynamic efficiency and a new treatment for the front spoiler. Finally, the light clusters have been redesigned to produce a new aesthetic, with colour-coded headlamp bodies and grey surround, combined with xenon technology for the dipped beam, with headlamp washers. The wheels are also a new design. On the aerodynamic front, the final iteration brings improved airflow around the wheels and there are small elements which reduce drag, while every detail of the floor has been designed to generate downforce while reducing drag.
The 12 cylinder engine in the Ferrari 575M Maranello, maintains the 65 degree V angle, four overhead camshafts, four valves per cylinder, the light alloy block, heads and oil tank and the dry sump lubrication system, with two scavenge pumps and one sender pump, separate reservoir and individual radiators. The objectives fixed for the new V12 engine in the Ferrari 575M Maranello were to increase both the power curve as well as the torque. It now has a maximum power output of 515 CV (379 kW) at 7250 rpm and maximum torque of 60 Kgm (588.6 Nm) at 5250 rpm (588.6 Nm) with an increase in mid-range torque of 1.5 Kgm between 1000 and 4000 rpm, when compared to the previous engine fitted to the Ferrari 550 Maranello. These increases in performance across the board have been achieved through a variety of modifications applied to the 12 cylinder. In particular these are an increase in capacity, a higher compression ratio, new fluid dynamics for the intakes and more general changes aimed at improving the efficiency and the management system of the power unit.
This car was auctioned off by RM Auctions in January of 2012 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona.
