The M5 features several F1 inspired engine and transmission controls including launch control, dynamic stability control, and the option of changing to either automatic or manual as well as the speed at which shifts are completed (there are 11 shift programs). Manual shifting can be done with either a floor shifter or the steering-column mounted shift paddles (another F1-inspired feature), both of which come in each M5. There is also a "power" button which, when switched off, limits the engine to only 400 bhp, intended for daily use. Switching it on unleashes the full 507 bhp for the Autobahn or track. Performance * 0-60 mph: 4.2 s - Road and Track tested 0-60 in 4.1 seconds (February 2006 issue). * Top speed: 250 km/h (155 mph) (electronic limited), 330 km/h (206 mph) (electronic limited upgradable option), and 334+ km/h (206+ mph) (no electronic limiter) citat din urmatorul link http://en.wikipedia.org/wiki/BMW_M5 in josul paginii iar viteza de 334 nu este cea maxima , am citit in alta parte ca turometrul se mai duce ... logic ca pe o masina mai ushoara m6 trece de 334km/h fara limitare
