It’s been a busy week of F1 car launches with McLaren, Aston Martin, Ferrari and Mercedes a🉐ll showing off their new cars.

While all teams are unlikely to reveal all of their new developments to the world just🍒 yet, there have been a number of key changes and trends across the grid so far.

One area of interest has been the front wing design of Ferrari’s SF-♏23.

Their new car’s front wing was fitted with front wing slot gap separators that were similar to what was seen꧅ on Mercedes’ version at last season’s United State🐟s Grand Prix.

Mercedes’ experimeไntal new wing fea🌄tured five enlarged slot gap separators, but was later asked to change it, which they did for Mexico.

Ferrari have gone d🀅own that design route, with a key change to the technical regulations allowing them to do so.

Mercedes’ design was banned because it was said to be ൲against the spirit of the regulations as it was for aerodynamic purposes.

The FIA rules stated that the slot gap separat🔥es could only be used “primarily for mechanical, structural, or measurement reasons”.

However, in December the rule changed slightly, removing the word “primarily” to outline that they must only sho🔥w a “structural connection” between consecutive front wing profiles.

Mercedes technical director Mike Elliott said at the end of last year: "I think there's a fuss about it, because in the regulations, it talks about the primary use being for mechanical or measurement purposes. And clearly, there's a secondary benefit of a♏n aerodynamic design that's in there as well.

"We'll decide whether we want to argue that one or not. It's actually not worth a huge amount. T🍎hat detail looks interesting, but it's not the big thing on the front wing."
