The FERRARI F1 2000 had an electro hydraulically controlled limited slip differential, the differential was an epicyclical gear type using five pairs of sun-gears running on needle bearings, a three or four-plate clutch , the clamping loads on which was applied by an annular hydraulic cylinder, controlled friction across the differential. The design aim of the final drive was driven by the desire to make it as narrow as possible as the width of the underbody diffusor is affected. The tripod constant velocity joints were placed as near the centre line of the car as possible, the elecrto hydraulically controlled limited slip differential was situated between them. The engine (maximum 18000 rpm) to the driven rear wheels (maximum 2800 rpm) required a 0.156 speed reduction and this was accomplished in three stages, the first stage was the gear cluster, the output shaft of which drives an intermediate shaft via spiral bevel gears (0.61 speed reduction), the third stage was the straight-cut final drive gear pair (0.306 speed reduction). Giving an overall (0.186 speed reduction) for the final two stages. Three alternative gear pairs (14/50, 14/52, 15/49) for the final stage were available.
