That car is about half a second slower to 60mph than a 550i, and yet runs about 12.35 for a good 1/4 mile @118mph.
So despite that lack of traction at the start it manages to uses its power to catch back up and cross at a similar time, at a slightly higher speed. If someone has the skill to get the start right anyway...
Or I suppose the other way to look at that is your car is still bloody quick, and more likely than not you'll beat an E60 M5 at the drag strip!  |
Correct. With traction you tend to lose MPH, not gain it. In fact, when you spin you pick up MPH as you are "lengthening" the runway. I have had people beat me early on when my car was a bolt on setup with better ET and less MPH - because they were cutting much better 60' times than I was - and keeping that traction all the way to the towers, while I was spinning and effectively standing still as they make their way down the track.
The E60 M5 is the last of the "smaller" GT's and using its trap speed - I know it has a better power to weight than the M550ix. If the M5 ran a solid 60 to get that 12.35 then it would take a tire for him to do it again against me. If that ET was with spinning - then he will likely run a 12.0 with better traction, tires, weight and DA at a better MPH than the M550ix - probably around 115. The M550ix would also lose MPH in a better ET run - removing special circumstances with super cool air and correspondingly fantastic DA - but on the same day I ran the 12.36 at 115 - if the car hooked better - I would gain a tenth or two and likely lose a MPH air two in the process - as the traction means less time on the track to increase speed (thus "shortening" the track").
It's all math in the end of the day.
