It's probably the clutch actuator releasing. Mine does it too - it's normal.

If you turn the ignition on without starting the car and cycle the gears you'll probably hear it making some noise.

Being as how the Forfour was a reworked Mitsu with an actual auto trans, my guess is whatever 451 noises we know about don't transfer to that car. Probably better to have a Mitsu mechanic check it out.

The 450s do this as well.

What am I missing here - the 450/451 cars are not related to the Forfour, other than being called a smart. No engine/tranny commonality at all.

The forfour shares the same platform and manual transmission as the new Mitsubishi Colt. The new petrol engines are the result of cooperation between DaimlerChrysler and Mitsubishi and both models are built at the same factory in Holland.
