Apart from the new front wing which is now more sharply curved, the rear wing has also changed compared to Barcelona GP. It is now completely horizontal in the center, while only being curved on the outer edges, while earlier it was one nice curve downwards.

Here's how it looked in Barcelona:

Here's the Paul Ricard version:

Wow, the endplate on top sure is long, but why is it curved like that now? The rear wing bottom section looks flat.

Hard to tell but it looks like twin element too (as opposed to triple).

Raised outer edges of the element mimic the rear wing style of recent years.

Overall surface area has increased too?

It's visible that they are searching for more downforce
especially at front.
Where this ugly looking wing closes a gab compared to the old one
to get more frontal wing area.
Same thing for rear wing: less curvy more frontal area
:arrow: more drag but more downforce
This may be important for the coming high downforce tracks.

Just realised how narrow the McLaren front wing is!!


As Jason pointed out - look at the width of those endplates (horizontal bits)0!

But I suppose with a camberline like that immediately inboard of the endplate, there will be larger trailing vortices created, and this is mclaren trying to reduce them.


Normally a 2 element front wing should generate less drag than a 3 element front wing. They've also got the 1st plane of the front wing at a much greater AoA to the airstream than every other team.

Well we're talking about Monaco configuration here, it's possible that these wings are only to be used there and not at any other event. Monaco is really all about downforce, the more you can get the better.

@Kilcoo: if a 3 element wing causes more drag, how come some teams use 3 plates anyway?

Gives more downforce.

Exact same philosophy as decision on flap setup for an aircraft design. More lift (downforce here) needed = more flap elements.

What is the black line on the top of the Monaco Rear Wing? On the barcelona picture, the line ecompasses the whole top rear wing.

I think that is removable counterflap. Enables mechanics to rip it off during pitstop instead of spending more time in lowering wing angle.

Why is everybody at McLaren Technology Center working on the aerodynamics when they should be working on SUSPENSION?
Does anybody agree with me?, the general perception is that McLaren's weakness is the engine.

Is it to decrease downforce and enable more top end speed?

Gurney Flap.

McLaren has been one of the more reliable teams this year. Their engine is not the problem.

I thought that (removeable gurney flaps) was now illegal in F1.

I have never heard that gurney flaps are illegal. But I think it is a good idea to ban them since that would reduce the aerodynamic efficiency of the cars (quite considerably?) while making it very difficult for teams to cheat.

There is no reason to ban the gurney flaps. It would not decrease the efficiency 'quite considerably'. It would only stop teams from having varied setup options on their vehicle.

How would reducing the efficiency make it difficult for them to cheat?
