2007 Mercedes-Benz ML63 AMG Reviews

Outperforms sports cars. It's the most powerful
naturally aspirated V8 in the world, 510 hp. AMG says
it all. It's as smooth as it gets going 150 mph+ like in
a lazy boy. As with any Benz, you learn something new
almost every time you ride for the first few months.

6.3 AMG enhine sound is awesome !
