Introduction of the smart fortwo, Model Series 451
Single-plate dry clutch
A single-plate dry clutch, consisting of clutch plate
and pressure plate, is installed on model 451.
An internal computer in the automated manual trans-
mission control unit evaluates the clutch load. If a
threshold value is exceeded, the clutch starts to pulse
as an overload warning to the driver.
If the overloading continues, e.g. if the car is being
held with the clutch on a gradient, the clutch is closed
in order to provoke a stall.
