McLaren MP4-29 Mercedes

[Pup]

I agree that the packaging between the 29 and the E22 look remarkably similar. I think the E22 has somewhat smaller inlets to the side pods, with the bottom of the triangle being a touch concave.

I think the 29's inlets are ever so slightly asymmetrical, no?

Front wing seems far more finessed than we're used to seeing from McLaren at launch.

The rear suspension looks pretty ordinary to me. I doubt that this is the 'special' version.

On the E22/MP4 29 comparison...
(unfortuantely we got jsut 3d renders for the Lotus, but I think they are fairly close to the real car, like the previous renders)

The Bodywork between the M of 'MP4' and the rear wishbones looks wide, just like the Mp4 26, 27 etc

It's hard to tell from those pics due to the different perspectives, but the philosophy certainly seems the same (from the air box down of course). I think it gives doubt to the rumor about the Lotus having some trick engine packaging, and is a good indication that the cooling requirements between the Renault and Merc units are similar..

And how do these pylons fulfill the single section rule from the regulations?

"3.7.8
Only a single section, which must be open, may be contained within any longitudinal vertical cross section taken parallel to the car centre line forward of a point 150mm ahead of the front wheel centre line, less than 250mm from the car centre line and more than 125mm above the reference plane."

How do they not? What makes up the second cross section?

To be more precise, it's about a single open section.
The FIA says:

"1.20 Open and closed sections :
A section will be considered closed if it is fully complete within the dimensioned boundary to which it is referenced, if it is not it will be considered open."

At the line in red in the picture it could be that the section is closed, but probably i'm wrong and it just looks like that.

Unless I'm misinterpreting your picture, you're taking the cross section in the wrong axis – longitudinal, vertical, means in the same plane as the camera there, not orthogonal to it – i.e. the cross section is seen as a plane, not a line from this camera angle. You need a side view to see it as a (vertical) line.

Perfect match.

beelsebob, here is the definition of "longitudinal vertical". When viewed from the front/back/top/ground you see a line. The red line should represent the cut in question.

Actually, I think this photo you posted in the Lotus thread is a better comparison...



So you're correct, it looks like the 29 is a bit porkier in the rear (as usual), and maybe a slight bit slimmer at the widest part of the side pods.

Two more pictures.

Sorry if someone already pointed it out and i missedit, but to me the Mclaren has a low chassis at the section AA. It looks like it's gradually increasing from 525mm at AA to 625mm at BB.

They introduced the silver RB'ish stay underneath the tube. Saw it the first time on a McLaren in that side view picture

someone should email that to mclaren, and ask them to paint it that way

No, I think it looks awful.
