In games you get a better result for the cycles by cheating rather than doing a physical simulation.
Live for speed IIRC did have a fully synthesized engine sound but most games now have samples and some clever interpolation / synthesis as mentioned by others.
Live For Speed also sounded pretty average, although it was still highly appreciated that they simulated it instead of fauxing give the type of game it was.
