Red Bull RB21

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Considering that the cooling system aero development is unlimited, it's quite poor to have such an inefficient system. However we have to remember that Red Bull tried something last year with the cooling system and it failed so they reverted back to a cooling system from 2 years ago, for the most part.
It doesn't turn.

I seem to recall that being about those mini radiators fed by the intakes above and behind the cockpit, rather than some new technology implementation. Those were one of the examples cited by Horner when he judged last year's car as "too complicated."

I think the sidepod radiators were repositioned as well.

Wow... didn't expect the floor change to be this mega..
the old floor's diffuser kickup starts beneath the 'hexagon' sticker location, while the new floor's diffuser kickup starts beneath the 'HD' sticker location. Basically, a 'longer' venturi neck in the old has been shortened in the new, to increase the effective diffuser 'volume' but making the expansion 'gentler'. That is an enormous change (perhaps this is an old RB20 or early RB21 floor circled back into the pool ?) , no wonder they struggled and didn't achieve the optimal setup in Mexico (perhaps Max missing FP1 did more damage than they expected or perhaps they are again 'away from the sweet spot' without the Monza floor).
