My car has a four-speed transmission. It is not as efficient as my daughter's five-speed.
Clegg's successor updated the car, to produce the Rover Fourteen, which featured the novelty of a four-speed gearbox.
Drive to the four speed synchromesh gearbox was through a single dry plate Borg & Beck clutch chain linked to the pedal.
A two-speed, three-phase motor drove the four speed gearbox to give a total of 8 spindle speeds from 170 to 2160 rpm.
It stood out from the other models at the time because it offered a mid-engine design and allowed consumers to choose a four-speed, automatic transmission.
