McLaren MP4-29 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 do not belong here.

Indeed, suspension parts are not considered as bodywork by the rules ("All entirely sprung parts of the car in contact with the external air stream"). But article 3.15 says the following :
Article 3.15 of the 2014 F1 Technical Regulations wrote:With the exception of the driver adjustable bodywork described in Article 3.18 (in addition to
minimal parts solely associated with its actuation) and the ducts described in Article 11.4, any
specific part of the car influencing its aerodynamic performance
:
- Must comply with the rules relating to bodywork.
- Must be rigidly secured to the entirely sprung part of the car (rigidly secured means not
having any degree of freedom).
- Must remain immobile in relation to the sprung part of the car.

[...]
The FIA could state that those wishbones "influence the aerodynamic performance of the car". I don't know if they will, but they surely can.

Wouldn't they be attached the actual changeable (as opposed to the main chassis) nose section anyway, so could easily be designed differently if what you suggest is right...

Turned down the chance to meet Vettel at Silverstone in 2007. He was a test driver at the time and I didn't think it was worth queuing!! 🤦🏻‍♂️

Can someone explain how these venetian blinds are beneficial?

These layman's eyes see drag but where is the benefit coming from that extra drag? More air directed over the top of the diffuser?

Interested to know...

IMHO they shouldn't, because it's not something that the other teams can't copy easily (even if the positioning of suspension means it's not as effective for them) and is an interesting design...

...so they probably will.

Well im assuming at high speed they open up and therefore are creating minimal drag, then when cornering they close and create downforce where drag is not an issue.

but i could be very wrong

indeed "influencing its aerodynamic performance" is much more specific than "aereoneutral" . "aeroneutral" could be interpreted as related only to the pure profile/shape/design (i.e. wing). but if one is honest is impossible to deny that such a thing does not influence the aerodynamic performance of the car

the movement of the suspension arm is minimal. probably they will "open" or change their configuration enough to produce some beneficial effect...but the drag will remain almost all there

So they made two superposed 'Blonchimont bells'' out of the upper wishbones ?

Are the black u-shaped things on top of the side pods at the front edge sensors or vortex genorators?

I don't recall ever seeing anything like them before

We think they're cooling chimneys....apparently Sauber have had them before...will try and find a picture...

I that picture they appear far too boxxy to be beneficial. And no longer look like they did in other images. Indeed they do look more like measuring devices from that angle
