I think most of the difference between M5's and 550s is occurring over the first 330ft. M5's have a lot more tyre and the transmission allows launch control with traction control off.

Seriously though, does tire width really make that much of a difference? I always thought that a few mm wider on PS4s only bought you a couple hundredths of a second. |

Correct. The transfer case and front differential are the same in m550 & M5.

‘The M5’s transfer case is also reinforced, as are the front and rear propshafts.” |

here are my runs from yesterday with 2 ppl on board..
my 550i has 623 HP and 870 Nm after instaling race box i think it can go lower than 3,5 from 0-100 with low fuel tank and better weather. But i think 100-200 is quite fast |

I hate to tell you, but with a 3.5 second 0-100kmh, your car is making about 600hp. This calculator has been super accurate for me over the years:

Was that dyno measuring brake horsepower or at the wheels? If at the wheels, both curves look substantially better than the stock rating of 523 hp, 550 lbft, even allowing for the fact that the official BMW numbers are usually a little low.

That calculator was created in 2004, when automatic transmissions were SLOW. Our current automatics are almost the same speed as the dual-clutch on the website. |
