Unless you spend a lot of time on a race track or your local autobahn, the 550i will blow by the M5/6 and many other high revving pseudo racecars. It's all about torque and physics: M5 has 380 ft/lbs torque @ 6100 rpm and weighs 200 pounds more; 550i has 360 ft/lbs of torque @3400 rpm, plus a torque converter and automatic kickdowns in the steptronics, which doesn't jerk you around in any gear. People who buy M5's are either speed nuts or image guys who haven't done their homework and have an extra $25,000 to blow and a car that can't even do more than 18 mpg on the highway. My 550i is capable after break in of zero to sixties around 5 or less and I have seen 30 mpg on level highways at 60 mph+ with the 32mph per thousand rpm in 6th gear. My 550i has no badge on the rear so many people who tail gate me or try to cut me off on the highway are left with their hearts in their mouths when I press the loud pedal to the floor. Surprise is worth at least 100 horsepower.
