The front wing is a new package, described by the team as featuring “locally increased cambers to extract more load”. It’s difficult to pick up those subtle profile changes, but what is very clear is that Red Bull has moved the two slot gap separators that I have highlighted with the red ellipses further outboard.

The rear flap trailing edge trim line, highlighted in green, is from the same family as it was at Zandvoort, Monza and Baku. However, interestingly there is no Gurney flap (noted in blue) added to the trailing edge of the rear flap as there was for the Zandvoort wing.

Red Bull might have an ace up its sleeve to potentially make Max a last minute challenger for the driver's championship even as McLaren sealed the constructor's championship in Singapore.

In addition, if Mercedes's pace also sticks, then that just means that Verstappen has a LOT more room to play with 199 points left on the table. I continue to not be a fan of the personality. However, absolute respect for the grit!
