That sounds like something you should be able to do with subtractive synthesis. If you don't have an analog synthesizer lying around, you can try software like maybe zynAddSubFx. If you set the pitch bend range wide, you could simulate smoothly revving from low to high RPM.
I have a Moog Slim Phatty that does an interesting/glitchy thing if you try to play notes that are too low for it, where at some threshold the oscillators slow way down. If you use pitch bend to ride the edge of that threshold, it sounds like a car engine trying to turn over, catching for a few cycles, stalling, and so on.
