i wonder why the renault f1 team on most occassions have about 5 km/h top speed lacking to redbull on straights. for those of you who thinks drag has noting to do with how competitive the car is. not only redbull is the quickest renault on straight , its also producing efficient downforce. next year will be a good comparision. we will find out how much hiding mclaren were doing with honda
No one is saying drag has nothing to do with performance, you are arguing with your self, like some kind of echo chamber. You never respond to the counter points of others, you just rinse and repeat.
The issue that most have is your assertion that the Honda PU is competitive with the Renault PU and it is the excessive drag of the McLaren chassis which is responsible for the poor top speeds. Brundle's statement is not AIUI a result of some calcs based on drag. They are figures which have been spoken of in the pit lane and as such can be used to verify the drag of the cars.
The formula I have for calculating power from speed and drag can be transposed to calculate drag from power and speed. in Austin, the McLaren had approx 1.5% more drag than the RedBull. Interestingly, 3.5% more than the Merc, so the Merc had less drag than the RB.
