McLaren MP4-27 Mercedes (pre-launch speculation)

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

Agreed – as far as I can see the packaging at the rear is the biggest problem on the -26. We know they can lower the gearbox down a chunk after last year's exhaust fad, and I suspect that the packaging could be yet tighter than they managed to get it this year.

And that rear compactness could be crutial for next season! Beacuse with lower rear section they will gain on downforce level from diffuozor, but on the same time they will almost keep almost the same level of low drag penatly! They must somehow equalise the of EBD downforce lost...

But there is problem in exhaust monting point? Maybe will be the most usefull if they squizze closer to the engine and try blow toward under rear wing?

There is a limit to how tight the sidepod can get. The heat has to be rejected from radiators, kers, exhuast etc. With the U pod, volume is at a premium.
The only solution to tightening is to not tighten, but to move the wheels further away from the side pod. This translates to an increase in wheel base.
I would go with as long a car as possible. It only need to be able to make the tightest corner on the calender.

Exhuast positioning is also critical with the U pod. It can in fact cause the car to lift if mclaren aren't careful. Dont want to much acceleration of air over the side pod. That is not good. They only need enough to prevent separation.
You want the air over the side pod to decelerate. From the sides you want sufficient speed over the beam wing. Therefore exhuast may be angled slightly inward.

I think 2012 will see highly under developed cars at the beginning. The teams will only converge on a good idea when they see one team running away with wins with a particular side pod shape.

Not many areas left on the car to blind side another team with. All innovations will be copyable.
For Sure!!

Sure that is the maine problem and space around it...

Yes it true, but i actually preffer to adapt on the most of rest races wihout Monaco, which is to specific race... I think the longer whellbase like Red Bulls will be slighty to occurred...

Yes that is the main problem how to mount the legal exhaust exit on u pods design.. And i mentioned in previsious post that the exhaus most be highest and toward the rear and as posibble...

Hmm but wait to the "end of beggining" is not good idea! Remember the many others seasons where other teams very struggle to catch up the leader team!

Maybe somebody has already asked this. What do you think that some engineer left the McLaren to join the Ferrari or Torro Rosso. Will they be weaker? or have they got younger, more talented men for this positions?

Everyone is always leaving Team A for Team B. it's not much special in the paddock. Some guys switch back and forth between teams too. Tombazis and Iley spring to mind. Theyve "pingpong'ed" between McLaren and Ferrari for quite a while, though Iley's jumped out of the loop now

Yes this is true. I've read the turnover between Mclaren and Ferrari is particularly high, which I guess is quite surprising given that they are such big rivals and located in different countries.

It's not that surprising when you frame it as "given that they have been established as one of the top 3ish teams for the past 50 years"

Thank you for your answers. It's very interesting indeed.
In other sports, football for example, it would be sacrilege

Anyone else noticed that Scarbs tweeted a french report that the 27 already has surpassed the downforce levels of the 26? Is this a surprise or expected?
Became a McLaren fan in the late 70's when I ended up laminating their Kevlar nosecones.

That's promising stuff. I hope they will start the season with similar levels of downforce to that of Red Bull.

Regarding the few staff decamped for Ferrari. Did they have anything to do with the 27 or they have had very little to do with it? Some reported a number of them left McLaren some months ago. Let's hope their departure will have no negative impact on McLaren's performance this year.

shorter wheelbase to protect front tyres... (did the rear tyre dimensions change?)

they will always say its better because we don't know the value of this.

Lewis will say during testing its the best car his ever driven as well. Happens every year. Last year he said it was better than the mp4-25 yet we know that that's not true because of the exhaust issues.

Its PR and to please the sponsors (as DC said in the BBC preview show last year)

I believe its better or as good when i see the times

Assuming google translate is right then apparently "The team also are working on an innovative solution that will not go on the machine from the first Grand Prix". Is this just another way of saying regular updates in PR speak or have they got something special to bring at the start of the season (when it will b harder to copy) like the f-duct !

Said it of the MP4-24 too.

Frukost- the rear was made stronger to soften the loss of the EBD IIRC
