Fons Adriaensen:
The data used by car manufacturers to describe engine noise
is a spectral description, where some small divider of the
RPM (depending on engine configuration) is regarded as the
funcdamental frequency. For each harmonic you have a smooth
amplitude map in function of RPM and throttle position.
Staring from these it's not so difficult to synthesise
something quite realistic.
The company "Staccato" tried to provide synthesized car sounds
for race car games in 1999, according to this page:

The 'industry standard' in this field is Head Acoustics
of Germany, who sell an insanely expensive system used by
many car manufacturers to 'synthesize' the sound of their
products. It's not a synthesis system, and it requires
recordings that can be made only if you have a anechoic
room big enough and designed to accomodate a car with the
engine running and the wheels on torque-controlled rollers.
Absolutely insane, but they are selling it.

Whats the target group for such a system? 10-20 customers?
I mean, how many car manufacturers (that care about the sound) are there in
Europe or the whole world? It sounds almost like one of the last financial
reports of SCO where they announce sales of four licenses of their product
and claimed a big success...

Not so many but they *all* care very much about sound, either
the sound of the machine itself, or the sound reproduced inside,
or both. You may wonder e.g. how Bose, known for the worst HiFi
speakers in the entire universe, survived. They did by selling
high end sound systems to manufacturers of expensive cars (and
PC-speakers to the unwashed masses).

It depends on what you're selling. If it's expensive enough
even *one* sale (i.e. a custom made product) can represent
a huge commercial success.
Things were like that when I started working in the space
industry 12 years ago. ESA would pay whatever was required
to have a system build to their very stringent specs. Times
have changed, now they're buying COTS from the lowest bidder.
