Vodafone McLaren MP4-27 Mercedes

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

"triggered-stalling system on the above-sidepod airflow"... For what possible benefit?

If you could do it, you'd do it all the time – the side pods create lift, so you'd want to dump both drag and lift no matter what situation you're in.

Maybe if you're managing downforce directly, maybe not so much if you're switching the exhaust flow vector

I don't think it's a big deal. Why not switch to something that works better if the team determines it is in fact better. The low nose can't be attributed directly to any poor performances.



Haven't been on here in a while..
Saw it from a mile away.
Yes it was only natural they switched. The regulations are so tight that every little performance advantage that can be had, must be had.

The mclaren nose was a dead spot; it was knowingly un-maximized. They knew it wasn't the best aerodynamically, but they thought it had something special to it. Desingn tradition and culture is to blame for this.
Anyway, there is no advantage aerodynamically with a low nose.
The aim is to get equal with the other teams, then find something to get ahead.

If you want to work the tyres right, you need the down-force; in the most consistent way which is at the center of the car. The higher the nose the faster and less disturbed the air is going to the floor and splitter.
For Sure!!

I was about to say that as well. I dont have an explanation for it, but that seems logical!

I must say they are still keeping it looking very sexy. I hope they dont go crazy stepping like all the other teams. Its truly a monstrosity of car design to allow such mongoloid looking cars period!

I don't think the change is for DDRS readiness. What stop them build the DDRS in with the old nose given the fact that the new nose is thinner? This is more about moving the high nose design philosophy for better airflow.

When you wrote "the higher the nose" do you mean relative to the back of the car or the ground or both?

I understand it as the higher the underside of the nose in relation to the ground. In other words more space under the nose.

Surely it's the nose to front wing rather than nose to the ground?

They run a test rig at the dffuser and some hump on the nose. What's that? Preparation for higher tub?

According to Whitmarsh, yes.

New vanes on the top of the sidepods as well.

I was going to ask the same, also that Ham running low nose, and But running high nose, do people think this is driver preference or just the usual back-to-back testing of parts? One more question, I think I'm right in saying it's the start of Q1 when parc ferme comes into action, so that's when a decision needs to be made?

The bridge on the nose has already been removed. So must have been the visibility test as mentioned.

Well its sort of Technical...the Mclaren crew has a new light systems on the jack to make sure everyone has compelted their duty by changing tyres (pointing at several pit failures from Macca in the earlier rounds).

Front wing looks to be working well for Button (visibility issues).
If someone said to me that you can have three wishes, my first would have been to get into racing, my second to be in Formula 1, my third to drive for Ferrari.
