I think it sounds 'weaker', 'less powerful' and 'higher pitched'. Let me
know if you think one of these   is good enough for being committed
Here is how I created them:
sox ~/engine-loop/engine-loop-1-normalized.wav sounds/engine1.wav pitch -60
sox ~/engine-loop/engine-loop-1-normalized.wav sounds/engine1.wav pitch -200
engine-loop-1-normalized.wav  from:

I don't know what exactly the sound engine of Trigger does, but I assume
it's either a pitch or playback speed shift, depending on car engine speed.
Trying out alternative functions for defining that effect might be
interesting for a programmer on the team. :)
The car engine standby sound is simply the lower boundary of the effect

Yes, we have to at some point, for licensing reasons :) If they are just
too brutal=loud, volume might even be changeable via code.
I admit that I quite like the current slide/gravel sound.
