They added a guide vane. That wasn't there in the initial picture posted a couple of pages ago.

You are right, the added the outter guide vane...the metallic unpainted one...although I am still curious about the bell shaped taper toward the exhaust exit and the fact the pipe is much higher than others who have outter blown diffusers and is not aimed downwards towards the underside of the diffuser at all...this is very unique in addition to the shorter length and the fact that the exhausts are more outboard vs the others...

Supersonic Nozzle. To make the air leave at one constant speed over a wide range of flows.

Aah it's a con-di nozzle, that makes sense! that helps in maximizing the benefit from the kinetic energy fo the hot gases!

Another shot of the lower/rake T-tray

verticle angle of the exhaust not xlearly visible from other shots... (contrary to initial impression it is pointed downwards)

MS didn't have that sensor, he instead has a different looking sensor
I also notice the T-tray in both pictures is now much lower to the ground in the front than in the rear...aka rake

Just out of curiosity, how are those sensors "attached" to the engine cover?

Good catch!

Not a clue!

Thanks bud!

Red Bull's, Ferrari's and McLaren's rakes still seem to be a bit higher than Mercedes's.

Well I think the front of the T-tray on the Merc is lower than on the MaLaren

I wouldnot go on and look for Rake angles on car which has wet weather tyres
Coz these rain tyres increase the ride height of the car on itself, especially the rear height

[DM0407]

It think the rake would be more easily determined when compared to the rear wheel seeing at the front of the car and the T tray would be sitting at about the minimal allowable height... Unfortunately those pictures only show the rear of the RB which does seem to still have an extreme rake compared to the others.

I see what your saying but the angle of attack should still be relative regardless of what tires you have on.

Same tires for everyone, so although there would be a small increase in the overall height both in the front and rear, it would be the same for all the teams

Agreed!

so a new type of diffuser gurney tab. should have known!

Yeah, it's an interesting idea this. Sort of bringing the Gurney around the corner to meet the channels turning outwards between the rear wheel and the diffuser, presumably improving performance out towards the back of the rear wheels. They're pretty big, tho, ay? Perhaps they act a little like a fence, as well, to help encourage more exhaust gases under the car?

This just a cheap and slap dash technique to get cheap and dirty down force.
It's a damn basically. The exhaust will flood into that little pocket and up the static pressure on the back of that diffuser.
It's a pretty smart but barbaric idea.
It's brain surgery with a sledge hammer.

The drag will increase a lot. They are taking advantage of their straight line speed.

Or it creates higher drag (blockage) on top of the floor which forces more exhaust flow along the underside of the floor where it's most useful.
