McLaren MCL33

[M840TR]

Elongated winglet on engine cover is back. This also means rear end is going to be more open than before as the 'valley' is flattened a bit.

No.

I wonder if they're trying condition the flow of air to the rear wing with those ?

Just more rear end downforce. Trying to take advantage of downwash from sidepods and engine cover to get a bit more streamlined air.

Helps extract air from the sidepods too, and condition flow to the rear wing.

We should throw a party when we're all right!

Doesn't that form a gurney flap at the end? That winglet has been tested extensively but i'm not sure if it was ever raced.

I don't think they had a gurney flap on it. Yes it was tested but looks set to be raced now.

So why doesn't any other team use vortex generators?

Mercedes does, copied them straight from McLaren.

Incorrect - Mercedes used them several years ago on the W04 and W05

No he's correct, McLaren used them before Mercedes, on the 2012 MP4-27. Mercedes then used them on the 2013 W04.

And McLaren copied them from Lotus, who introduced them in 2012.

Definitely not.

The top of the sidepod is a lift generating surface. Teams put in a lot of effort to reduce it's topside area and/or find ways to push air away from the top.

There is zero reason to place the element there if you are looking for downforce, considering the free area exists far above it's position as well.

This is more about managing exiting airflow.

I know the top of sidepods are commonly dedicated to pushing air downwards to the diffuser, but the Mcl33 has a tiny winglet adjacent to the vortex generators on top which obviously is directing air to the rear wing area. My point was that the winglets at the back do manage exiting air, but by extension they create rear end stability, which the car clearly lacks.

Think Lotus only had one on each sidepod though didn't they, Mercedes had one of those as well in 2012 to be fair. Red Bull had a double one in Valencia at least as well.

I'm talking about the group of 3 that McLaren had in Germany 2012 that Mercedes turned up to Australia with in 2013.

Who stuck the first single one on and where I couldn't say, could well be Lotus. Think STR could lay claim to the first to use 3 in Korea to be fair as well but different config to the McLaren/Merc ones.

[charliesmithhd]

The difference is that before, teams used the vortex generators in a line across the front of the side pod, but now McLaren have them staggered. What's the reasoning for this?
