In the 1950s and 1960s, Cotal used this same technology to provide an electric
clutch (with full manual changes through a normal gearbox, but no
clutch pedal) for
small Renaults like the Dauphine and Caravelle, but it was
relatively unsuccessful — it needed to transmit the entire engine torque through the
clutch, requiring a
relatively large and powerful
clutch that tended to give trouble with the sliprings.
