Wiesmann brothers had been aware in good time of the financial
risks involved in setting up a vehicle production facility.
For this reason, they first set up a facility for producing
hard tops for convertibles with the appropriate storage system.
They had a convertible in the family, and this proved them how
essential a solid roof was, especially in winter. Along with
not inconsiderable private funds being invested in the roadster
development, the hard top production provided a long-term and
solid financial base for covering the huge development costs.
Fortunately, these hard tops were very well accepted by the
market; on the one hand, they guaranteed financial survival,
and on the other, they attracted the necessary recognition through
cooperation with the car manufacturers. This culminated in a
supply contract between the BMW AG and Wiesmann for motive power
engineering for the roadster they were developing.
Then in 1993 it happened:
The Wiesmann-Roadster with BMW technology was launched!
