McLaren MP4-28 (pre-launch speculation)

[FrukostScones]

For what reason they should keep it low (the front bulkhead)? The only reason is to use an old design due to cost saving.
Or to keep the car pretty? lol (sry).
omnicorse.it said so, people who have seen the car say so (ok, rumors, but check the rumor history), they tested it, we have a modesty panel, the nose went from low to high(er) already in 2012 (because the tea tray issue), so well what can I say more.

I'm not saying thay should, but rather they could. Advantages could be lower CoG and a bit more front end grip. As well as a better CoG gain when they (possibly)opt for a pullrod front.

Well I say they dont, doesnt make it the truth.

They indeed raised the nose, it was around the same height of the rest of the field. Then the tub height change wont make a real difference, since airflow going under the nose tip goes there anyway, no matter the tub height.

There's possibly a bit of a grey zone between the McLaren tub height and the tub height of others. The higher tub got more area under the nose, but the McLAren tub got a bit of a lower CoG on the front.

Also Red Bull lowered their nose last year and iic a few others didnt have their nose tip at max height, so it shows that maximising area under the nose isnt everything

Ok, but as they will likely use the Ferrari style front pull rod because of aero reasons, maybe higher attachment points are necessary to make the conecpt work aerodynamicly.



but the front pull rod speculation is another matter...

[wesley123]

True. either way I am looking forward to see the MP4-28, only 16 days but still too long lol

In my memories, Ferrari had a problem, with the big rod angle (almost 90deg). I had read somewhere, that the pull rod works better or setup easier, with smaller rod angle. In this line of thinking, pure mechanically, the pull rod will fit better in lower tube

On the above link you have is the first picture of the mp4-28, put on the twitter page of Vodafone Mclaren Mercedes. It's a part of the car, but we could not certainly tell what part of the car. The most interesting opinion was this: "It's the new stealth version with low drag look no waves. I know Jenson Button and Perez are smooth drivers but wow. It's not a sub or a plane its a McClaren.". What do you think?

Check out the previous two pages. The picture is taken from the cockpit towards the front of the car.

I think a lower monocoque would be better for the pullrod front suspension. The pick up point will obviously be lower making the rod angle more than that on the Ferrari putting less stress on it.



McLaren Mircea you said "It's a part of the car, but we could not certainly tell what part of the car." im not sure if you was joking when you said it but if you're not to me it looks like the top of the monocoque pretty much the view the driver would have looking out of the cockpit.

The entire point of front pull rod is to get more clean air under the nose of the car, a low nose would defeat the purpose.

there are no suspension parts under the nose, a high nose and monocoque is to get more air under the nose not the suspension lay out. the pullrod suspension lowers the centre of gravity (the lower the monocoque the lower the centre of gravity) and aid aerodynaics through the suspension area as the pullrod is more horisontal.

little contradiction here(if you are thinking of the Ferrari talk),
also i think front pull rod marginally lowers the center of gravity because of the suspension parts are in the bulkhead and the rod....

anyway, pull rod front extreme worked mechanically well in the Ferrari so no need for a low nose when pull rod front is there because of aero reasons.

[allstaruk08]

how is it a contradiction? a pullrod suspension in a lower monocoque (McLaren) V's a pullrod suspension in a high monocoque (Ferrari) which will have the lower centre of gravity? my guess is the McLaren like i was trying to point out...

ok, so you say that with a pull rod front suspension we can have a lower nose (lower cog through that) and lower cog through the pull rod front suspension.
But hey, we don't want a low nose/tub, and as we have seen on the Ferrari it worked well at least mechanically, so what are you trying to say? that with a lower nose/tub the front pull would work better mechanically (or the other way round) and we could haver a lower cog?
also the rod would be more angled if lower tub, you wouls have the dwishbones more horizontal
i guess with suspension parts under the nose beelsebob meant the mini double keel.

The reason it improves the airflow under the nose is because it raises the angle of the wishbones, because you don't need a push rod joining the chassis above them. That means that the lower wish bone is higher up... Meaning more air can flow under it without getting disturbed

[allstaruk08]

ah beelsebob i get you sorry, i thought you meant literally underneath the nose lol

im not disputing that McLaren wont go with the high monocoque FrukostScones, yeah it worked with Ferrari and could work for McLaren. i just think maybe McLaren might stick with the shape they have now or something very similar they've had the last 4 seasons to realise they can go full height with the monocoque and they haven't. just trying to come up with different ideas not argue with you guys
