  1. Dont disagree, but hard to say how long he was in 4th gear.

  2. Wouldnt make much difference, believe it or not.

  4. Not easily, for sure not; lest you literally tow the mondeo with a rope. Runways cant be used to test the top speed of any "faster" car, its just a fools errand.

  5. Takes 210-220hp at least to go over 150 in an xc70, so I guess you got one of the hotter versions?

  6.  @InActionReaction  628? That is some stage 3, cant be much stock left in that engine bay, if its supposed to stay in one piece for long full throttle durations. Oh, and with that power, a true 200mph isnt out of the question.

  7. Most faster cars take several miles, yes.

  8. Did you really think you can hit the top speed of a car on a normal runway? Really? If you did, I can only conclude you havent gone very fast before and/or dont know much about cars. Sorry, just calling it as I see it. A mile or even 2 isnt enough in most "faster" cars. Thats why testing the "top speed" on a runway is a fools errand.

  9. Flying start makes little difference in this case.

  10. To be fair, a flying start doesnt make a big difference though in this case.

  11.  @jamesbrook16  It does, but by a very small amount. Think about how much distance it takes to accelerate to 60mph from a standstill vs how much distance it takes to accelerate from 140 to 141 mph, and you will realise it would only increase the end speed by 1 or 2 mph at the most in this car. Thats why a "test" such as this should never be done on a runway, they are just too short, it takes an enourmous amount of space (3+ miles) to reach the true top speed in most cars such as this.

  12.  @jamesbrook16  First, I want to thank you for giving me opportunity to explain this, as a former physics teacher it is very rewarding getting to do this again. Secondly, dont feel bad about thinking its the time thats the limiting factor, its a very common mistake. Now, with that said: since we have a fixed distance of runway, we are limited by that, not time. Which means that average speed is very important. If you do a 0-60 in 9 seconds, your average speed for those 9 seconds might only be about 40 mph, meaning you travelled 161 meters. This is how much you gain with a 60mph flying start compared to a standing one. Now on the top end we already have 141mph, and want to get to 142. Lets say the average speed is just 141 to lowball it. This give us just 2.55 seconds of additional acceleration until the extra 161 meters are used up. Not much, right? And yes, close to the true top speed, it can easily take 5-10 seconds between each mph gain in most cars. This car wasnt at its top speed, so it will accelerate quite a bit faster, but not more than one mph per 1-2 seconds for sure, which is why I said, 1 mph; 2 at the very most gain with a flying start. Now you see why at least 3 miles or so is necessary with this car, the distance ticks by fast when trying to squeeze the last bit out. Cheers.

  13.  @jamesbrook16  Means a lot, thanks. 👍

  14. It actually wouldnt, believe it or not. Because its the track length limiting them, not time.

  15. Flying start doesnt make a big difference though, to be fair.

  16. Not possible to test top speed on a runway, so it was always doomed to failure.

  17. Rolling start doesnt make much of a difference.

  18.  @Oldcarsrule0184  A bit, but not much. Maybe 1 mph, for sure less than 2 in this car.

  19.  @sprintermaximus  Agree, but it wont make much difference. Think about distance traveled per second at different speeds, and it should become clear.

  20. No, it makes little difference.

  21. Unlikely.

  22. Wouldnt have mattered much at all though.

  23. Close to nil difference, believe or not. Much less than 1mph gain.
