Pininfarina Sergio is a incoming concept car and will be exhibited during the Geneva Motor Show (7–17 March 2013) and is a heartfelt tribute to the memory of Sergio Pininfarina, who died July 3, 2012, at the age of 85 years.[1]
Sergio is a roadster car that looks to the future, extreme, compact, sporty, racy, pure and sensual. An exercise in style that Pininfarina has decided to expressing themselves on the engineering of the Ferrari 458 Spider, which keeps some elements.
An element of innovation is constituted by floats and aerodynamic headrest attached to the roll rather than the body of the seats, becoming almost elements of the exterior more than the interior. In addition to ensuring maximum purity of the lines, this solution also acts as a fairing of the heads in the rear. In front of the door panel, in a small recess of the channel, are housed the two helmets. Made on a specific design of Pininfarina in collaboration with Newmax, helmets of Sergio are personalized with the color of the exterior car.
the Pininfarina Style Centre has transformed the original car, a Ferrari 458 Spider, into this roadster car with calculations and tests in the wind tunnel of Grugliasco to optimize aerodynamic performance. In particular, has been realized a bodywork totally new, full carbon, with a weight savings of approximately 10% in relation to the bodywork original aluminum, all to the benefit of acceleration and recovery. Compared to the original car, then, have been included in light alloy wheel rims monodado by 21 ', with specific design, and a hub derived from Ferrari 458 Challenge. The aerodynamics have allowed us to achieve more interesting results, starting with the creation of a virtual windshield. The elimination of the windshield would, in fact, the arrival of a stream of air pressure increasing with the speed on the head of the driver and the passenger. The engineers and designers at Pininfarina have designed, built and tested an airfoil placed in a shape of the bonnet, which produces a double deflection of the flow of air entering the passenger compartment. The first deviation is made from the wing itself, the second from the air that accelerates the channel created between the airfoil and the corresponding shape of the molding in the trunk. The result is that, thanks to the virtual windshield, the air passes above the heads of the driver and the passenger, greatly increasing the comfort. This effect also contributes to increase the aerodynamic downforce on the front axle of the car. The virtual windscreen is already effective from 50 km/h.
The loss of aerodynamic load on the front axle, due to the elimination of the windscreen, has been recovered from a wing inserted in the front bumper. The wing is calculated in the form and dimensions such as to give the required load at the various speeds and, at the same time, allow a correct flow of air to the radiators of the cooling system, the front seats, in a central position. To improve the protection of the occupants was made a roll-bar which has been applied a fixed spoiler that increases the downforce on the rear axle. The attention to detail goes so far as the rearview mirror, center, whose form has been aerodynamically optimized to link up with the air flow of the virtual windshield. The air intake of the engine is channeled from the air inlets in the two sides. The air vents at the base of the roll bar conveying the cooling air to the oil coolers. Overall, the Sergio offers performance of a real sports, with a shell, the torsional stiffness greater than that of the spider of origin, thanks to the reduction in the size of the doors, and with a reduction of the total mass of about 150 kg compared to the spider. This allows good handling and a further improvement of the acceleration, the value of the 0–100 km / h, even at the top of its class, is estimated to fall below 3.4 seconds.
