Hallo!
In der englischen Wikipedia findet man folgendes:
Chitty Chitty Bang Bang, the car of the film, was not a pre-1930s car at all. Four cars of this type were purpose-built in 1967 for the film, and these, due to using Ford Zodiac Essex 3.0L V6s, would easily keep up with the fastest vehicles of the day. Different Chittys did different duties (i.e. one was set up for floating out at sea - it was mounted on a speed boat and was remote controlled), and Chitty did actually fly (a partial car - hood only - being mounted underneath a helicopter in certain scenes).
Zum Nachschauen:
