I saw the comments by Cristian Horner regarding the Renault power deficit compared to Ferrari and Mercedes but I don't fully agree with him. He said:
"If you look at the rear wings on the cars, we're running Spa levels of downforce [at Silverstone] and everybody else is running that bit more.
"In qualifying I think every single corner we were quicker than Sebastian, but we just hose time down the straights."
Isn't it strange that you have less downforce and still can be faster on the turns? I think it's looking like McLaren last year. They were thinking they had the best car and a --- engine but it was not true in the end.
Ok, the Red Bulls might be using a small rear wing, but the fact they are so fast turning says to me that, somehow they must have more downforce, and consequently more drag.
I would put it to the aggressive rake they use.
RB ran like half the wing level compared to merc and ferrari, which more than makes up for any supposedly draggy elements they might carry. Ferrari is also running tons of rake, yet it also ran massive amounts of wing in silverstone (double whammy in terms of drag), yet was still able to top speed traps.
Silverstone exposed renault and honda for what they trully are, that is nowhere against ferrari and merc. Doubtful they will ever be able to catch them. We've been waiting for years on a meaningful convergence, but in my opinion the difference is as big as it has ever been.
On corners which are not power limited (so not T1 abbey and not T9 copse) they have indeed been faster. Not by much, but they also weren't carrying much DF on the car.
Rake on the Ferrari "looks" less than that of Red Bull. But i will concede that it "looks" more than what Mercedes carries. If the car carries X degrees of rake & Y degrees of angle of attack on the wing, the total angle of incidence that the freestream air "sees" when it hits the rear wing is X+Y degrees. If your rake is significantly higher to make your aero work, trimming the wings a little will not help your cause a lot.
There is no way of knowing how efficient the flow through the radiators and the internals is.
You can also see the way the bargeboards are placed on the Ferrari and the Red Bull, with the latter being a lot more curved compared to the Ferrari's. I am not for a second denying that Renault is underpowered, i am implying that Red bull's aero philosophy is just as draggy. Combine these two and you end up with an unholy compromise on all the power sensitive tracks. Red Bull should start quoting their drag coefficients if they make up power deficit numbers to their competitors.
Ferrari's aero philosophy has changed significantly from last year and you could see from the beginning of the year that their low drag philosophy was paying off even when their engine was clearly #2.
Horner's whining does absolutely nothing other than fill columns on websites.
