V12 engine

I put this on facebook in the week its awesome. Anyone remember that scale model Ferrari that was on Top Gear a few years back, where they built the car exactly the same but in miniature even down to an ignition key that started it up you just needed fuel and a driver who was about 6 inch high
 
And I thought somebody had grafter a v12 into a cougar when I saw the thread title.
Saw the dinky engine vid on another forum, can't help wondering if it's running on fuel or just being turned over by compressed air or something ?
