The first Formula One car to use a semi-automatic transmission was the 1989 Ferrari 640. This system used hydraulic actuators, powered by hydraulic fluid, and electrical solenoids for controlling the clutch and shifting, and was operated by paddle shifters mounted behind the steering wheel. Another paddle on the steering wheel controlled the clutch, which was only needed when starting from a standstill (i.e., stationary). The car won its debut race at the Brazilian Grand Prix, however, for much of the season suffered from reliability problems. Other teams began switching to similar semi-automatic transmissions, and the 1991 Williams FW14 was the first to use a sequential drum-rotation mechanism (similar to the system used in motorcycle manual transmission) to produce a more compact design that required only one actuator to rotate the drum and move the gear selector forks, and this was the direction that semi-automatic transmissions in Formula One took. A further development was made possible by the introduction of electronic throttle control soon after, which made it possible for the car to automatically rev-match during downshifts. By 1993, most teams were using semi-automatic transmissions. The last F1 car fitted with a conventional manual gearbox, the Forti FG01, raced in 1995.
