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.
