McLaren MCL32 Honda

[PhillipM]

Most of the first test is usually about testing aero correlation rather than the actual performance of the parts, which is why you see Red Bull, Mclaren, etc, all running relatively basic setups. Even Merc and Ferrari haven't bolted a whole lot on for testing yet, that usually comes at the second test.

interesting curvature on the suspension arm ...

Removed some Posts about detuned PU and testing Performance. Please stay on Topic Guys.

Couldn't find a better one.

Looks quite attached to me. What do you guys think?

[Jef Patat]

To me it looks too low res

Outch... this song at 24:47 even on day 3

Just sounds like he's off the throttle and it's cutting cylinders, it clears as soon as he touches the throttle before diving in the pits.

Completely agree flmkane.

With regards to a basic looking floor, it's my view they are simply testing a base design in this new and different layout. Once they understand how the base works with the rest of the car, then they can start cutting slots and adding shapes to fine-tune the airflow where needed.

It may also be the case (which has been hinted by Eric Boullier) that they have something special yet to come in that area. He's been quoted several times suggesting that when other teams see it, they may lodge protests, but that they are convinced their innovation is legal. I can't see anything fitting that description yet, so it may be some sort of floor/diffuser design that they're holding close to their chests for now (less time to copy). Of course, it could be something else entirely.

Due to the wider & taller diffuser and an increase in rake present on the 2017 cars, the surfaces of the brake ducts, diffuser, floor, suspension arms and rear tire sidewalls are now all in closer proximity to each other. Perhaps they have unified all these elements in a unique way.

That was for the suspension. I need source for this. Him saying those words.

This involves the suspension.

Structural suspension components are not considered bodywork, so there's potential to combine the suspension & diffuser in unique ways that aren't constrained by bodywork regulations.

For example: they could form part of the diffuser ceiling with the suspension arms & brake ducts. As such, the diffuser would only be fully formed when the rear suspension is minimally compressed.

At higher speeds, when the rear suspension is fully compressed, the continuity of the diffuser ceiling would be broken. A sort of DRS for the diffuser.

Do i only have a feeling, or is the Honda engine whistling much more than others. Also, u can see a little bit more of the car taking corners.

According to de la resta : ""The McLaren is more nervous than I expected," he told El Confidencial.

"I see a Fernando (Alonso) who has to work on the steering wheel more than is ideal. The car is unstable in turns 1 and 5 and tends to lock wheels.

"No one is attacking like Fernando. I really did not expect the McLaren to be as restless on these wide tyres," de la Rosa added."

I agree we can say that she's struggling in some corners... take a look at : 11:33 and 11:54

All i can see is a wet patch where he hits the gas pedal and rear snaps off which is logical. When Ferrari comes behind him he has exactly the same problem, but a little less of it due to the fact that he stepped on the gas pedal a little later.

Redbull had no problem at all, as the driver went into the corner slower and not in such an angle, acceleration was softer as well.

Atleast to me it looks as a wet patch issue, or an engine mapping needing a fine tuning.

The fact is that the car isn't struggling on the wet part... but on the dry one !
