Ferrari F50 Structure

The body was built entirely from composite materials with carbon fiber, Kevlar and Nomex honeycomb molded in one of five available colours: red, red Barchetta, yellow, black and grey Nurburgring. On the Berlinetta version, the function of the integral hard top was to complement the structural elements. On the Barchetta version, the bodywork element incorporated the anchor points for two roll hoops. The engine was visible through part of the transparent, vented engine cover.

The chassis of the F50 was made entirely of carbon fibre, weighing 225 lbs and offering a torsional rigidity of 25,677 lbs-ft/°. Like a Formula 1 car, occupants sat in the central tub formed by the chassis, and the aeronautical rubber fuel cell was located in a protected position between the passenger tub and the engine and rear suspension. The result was in advanced driving position, with a front to rear weight distribution of 42:58. A load-bearing element, the F50's engine acted as a support for the suspension, rear bumper and bodywork elements. To guarantee perfect suspension operation, the engine-transaxle assembly was rigidly attached to the chassis.

The suspension and engine-gearbox assembly were mounted via low-fatigue light alloy inserts co-polymerized to the chassis. To optimize the structure that made up the fulcrum of the entire system, even from the safety viewpoint, finite element calculation techniques were employed, using programmes that included sandwich elements and multi-ply shells, typical of laminated composite structures. Engineers and designers had to solve problems of the long-term stability of dimensional and structural elements. Tests were carried out on computerized vibration benches.
