I thought I explained myself in my original post?
Does the Bat-Pod make any noise in the movies? You can clearly hear the engine come back on when the lights turn on, as well. Essentially, The Tumbler turns into a front wheel drive vehicle while in stealth mode, using the same engine that the Bat-pod does, which sounds like an electrical motor in the movie.
