Re you sure though that drag doesn't affect these cars till 250kph...?
Not entirely true, but I get your point that it only becomes a real issue at higher speeds. Drag is proportional to velocity squared.
Yes it's certainly not the reason for accelerating away, that is something tp do with mechanical forces. Suspension setup, gears etc although with so many gears in the cars it is unlikely to be an issue.
I'd read before that drag doesn't actually reduce lap time by as big an amount as some think. But now I'm curious to understand when drag does become visible in two identical F1 cars who's only difference is wing size.
Where would one start to noticeably pull away in a drag race. I'd love to see that.
My understanding is that it becomes noticeable at around 250km/h, it doesn’t influences it as much below that point and starts making a difference from that point onwards.
That’s why I mentioned that if the gap is created early on an straight is most probably a traction issue… If you look at the telemetry of Hamilton and Norris, in the back straight you will notice that both cars are at 248km/h at the same point of the track, nevertheless by the time they reach 290km/h there is a 2km/h in favor of Mercedes, which is maintained until the end of the straight, this would imply that even if there is a bit more drag in the MCL60, the difference is negligible against the Mercedes and less than 0.1 is loss by McLaren due to top speed drag.
The main straight (longest straight) shows a little bit different picture, both the Mercedes and the McLaren have the same speed all the way to 279km/h… With the gap growing after that point until there is a 5km/h difference… The question is if it’s due to drag or deployment or a combination of both.
But normally, we similar exit speeds and traction, cars won’t see a difference due to drag until 250.
