Andy Farnell has some
interesting procedural techniques for engine sounds in 'Designing
Sound'. I've found better results combining some of his techniques with
actual engine recordings.
You could go the 'traditional' method and record engine sounds at
different RPMs and varispeed (read an array at different rates) and
cross fade between them. It will take some effort but should take you
somewhere.
If you want to design more realistic sounds it might be worth reading up
about the techniques used in actual game engines (especially on load
and off load sounds).
I'd made a prototype some time ago, in Max/MSP, that was a combination
of granular resynthesis, additive synthesis and a bit of convolution.
Not the most efficient technique, but it sounds quite alright.
