That answer would probably depend on what you mean by "powerful". One could think of civilian vessels vs military, firepower vs Engine Power etc etc. Probably a nucleart Aircraft carrier would be considered "most powerful" - but definitely not "most useful"!
If you mean by speed and wether or not it is a production car, then it is the bugatti veyron super sport, it has a 16 cylinder engine with 4 turbo chargers. It produces 1001 bhp and an air brake witch is very powerful
As with most cars, you can get a more powerful engine, shorten or buy a new muffler.
