Mclaren MP4-30 Honda

[PlatinumZealot]

It seems that McLaren and Mercedes are running without an independent toe link on the rear.

Or at least I haven't spotted it yet on either car.

The back slanted peice is the toe link. All five members are there. U just have to look a bit more....

Yes, they try to direct the air in the same direction and upward as what the diffuser does. The wake of the tires tends to create a V wake that create a convergent flow structure where you want a divergent instead.

Hello Matr!x
I do believe that this is the correct layout of the MP4-30 rear suspension.

Basicly they moved the toe arm (RED) in front of the driveshaft (ORANGE), while the two wing-shaped arms towards the back of the car (YELLOW) are joint together in a triangle.

(In CYAN the upper wishbone and in BLUE the pull-rod lever).

They have been able to raise all the arms and get a cleaner area around the first half of the tyre, obviously for aerodynamic reasons.

Here's a comparison and closer look, with some interesting insights.

hi Giando
i've put our speculations about this rear suspension geometry (focusing on lower part).... because i think there wasn't much attention about it, here on f1technical...
your recostruction is very good ...maybe the pull-rod lever must be put more oblique... =D>
They are all aerodynamic advantages... but i consider, however, a strange solution...

(1) I agree... and it's quite strange, considering how carefully this forum usually analyzes each single part of the cars and how 'new' is this idea from McLaren!

(2) Absolutely... just a very rough scheme... no intention to be fully precise... just to give the idea of the layout.

One for the aero guru's
The left endplate seems to have a shroud with an exit near the Trailing Edge.

I tried adding a zoomed shot, but only new and they won't left me

[Just_a_fan]

Do you mean on the inner face of the endplate just above the vertical strakes? If so, that's a reflection of the engine cover and the "slot" you see is the end of the engine cover that vents the engine bay heat. Look to the right of that "slot" and you can just make out the reflection of D and A of the word HONDA on the engine cover.

[Rick Diznik]

Doh off to specsavers for me

[adrianjordan]

Not the first time a reflection has played tricks on the eyes of this forum!!

Mclaren must see a benefit to not integrating the drive shaft with the suspension as this staggered top and bottom a-arm arrangement they have is clever, but a risk as it looks very particular in its pickup points and not almost infinitely adjustable as Mercedes' carbon encased gearbox practically is. Mclaren could have have the situation where this car runs particularly well at some circuits but not others.

There are more pages in this thread than the MP4-30 did on the last day of testing in Jerez.

and so?

it looks pretty good and planted on most of that video,so that Kravitz comments were most likly made when Alonso was on old wet tires and the track was pretty dry by than.
