McLaren MCL32 Honda

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

Interesting aero testing
Nope, no, no, no.

That is McLaren just adding drag to make the Honda PU look bad. :wink:

Not a loop hole. I read somewhere that this is permitted in the rules.

you are allowed to add winglets around the upper part with max. height of 20 mm
We will allow them to use non-structural fairings around the upper part, which can be no more than 20mm from the main structure.

Cool photo, thanks for that :wink:

Can one of you aero guys let me know exactly what that does please ?

Many thanks,

This creates lift -negative downforce- and a bit of drag. So on its own this is not desirable. What that tells me is that the halo creates substantial issues, either with the airbox or with airflow attachment to the rear (or both), which you can remedy through using winglets like that.

What I think is happening, is that the frontal tube of the halo pushes airflow higher up, away from the airbox and bodywork around it. This will rob the airbox of air, which has its impact on the PU, and the rearwing of airflow. So they have to come up with a solution, even though all of this is not desirable.

It is not a loophole, it was announced that teams will have cetain degree of freedom with their halo devices to tailor the airflow to their cars (airbox, rearwing etc.).

Other teams will have their own interpretations, McLaren is just the first one to try it on the track.

It’s also about controlling the Halo’s effect on the drivers helemt.

The shape of the bar is also altered, flattened across the topside. Different from the cylindrical versions seen previously in tests. We can surmise the the HALO supplier to the teams (as mentioned in the technical regulations) can make custom shapes per client.

I knew about that, but somehow i thought they would write the rules making sure the fairing was one piece and covering the Halo, apparently not.
