Bugatti haven't the balls to do it. If anything, They'll just cannibalize one of Audi's Le Mans prototypes and badge it as a Bugatti...kinda like what Bentley did.
Those usually serve SOME purpose... still doesnt get around the fact that the engine will be rubbish for racing. I mean it will obviously get the car moving very quick, but its just overkill, heavy overkill. Not to mention it would probably overheat under strenuous use.
