InsideLine has taken the time to review the new 2009 Mercedes-Benz ML320 Bluetec that, as they state, can run for 600 miles on a single tank of fuel. Compared to a normal diesel, the ML is fairly quiet. There is a low diesel rumble when you put your foot down, but it can easily be drowned out with music.
