Low-speed traction improvement was the target they were saying publicly in 2023, for the RB20. That they have achieved it, we have witnessed in all the quali+races so far - the traction advantage that Ferrari enjoyed for 2 yrs is no longer there for them, the Redbull is on par (or almost on par) with the Ferraris (undisputed kings of rotation and traction in this new rules era).
Regarding the loss in speed in the plot (the S's, the two straights, turn12 sweeper) for the RB20 w.r.t RB19, what is the consensus in this forum, after taking into account the difference brought by factors like :
- unfavourable wind direction
- wing levels
?
If there is no wind factor and same wing level used, is the RB20 inherently more draggy than the RB19 (due to more downforce from higher efficiency wings - front/rear/beam and diffuser) ? And when they say they have reduced drag with Suzuka update, surely they must be referring to launch edition RB20 and not the RB19 ? How else to interpret it ?
