McLaren MP4-28 Mercedes

He's right though..

I've been watching the timing screens for the last two days , and all cars have started well then tailed of dramatically.

This afternoon Perez and Hamilton did some longer runs ,starting with an initial 1m23s (ish) then within the next two laps their in the 26s,27s and finishing in the 1m31s after approx 10 laps.

The best run I've seen was yesterday when Kimi did 4 consecutive laps of around 1m23.6 or .7 before boxing a 6 lap run.

The McClaren has had (as most have) rubber build up at the rear floor near the tire heat sensors and it makes me wonder how the cars with 5 element wings are going to fair when all that nice gummi rubber starts being flung off and enters the following cars FW.

The McLaren has been looking great on the high fuel race sims – they've been going from 1:28 to 1:30 in 12 laps, while RedBull were going from 1:29 to 1:34 in only 8.

Simple lid for electronics?

[bhall]

More likely ballast.

[Nando]

In that little box? wow had no idea about that. I also expected the put ballast inside the 4 wheels.

[mx_tifoso]

That little box just might hold electronics inside imo (sensor). And the ballast might actually be surrounding it while filling up the entire central (spec) section.

Doesnt driveability decrease when you put ballast in the wheels? because of inertia or something like that?

but yeah, most likely is a spot for ballast, electronics seem like a no go to me because of it's quite vulnerable position.

[bhall]

I think he meant within the dimensions set by the wheels. At any rate...



The part you see on top of the wing likely just connects to the ballast attached to it under the wing.

fuel. The mclaren has neither looked great or bad compared to the rest on tyre use thus far.

More likely ballast.

What is ballast made of on this car, and how much would a piece like that weigh? How many would be typically located on the car and would they be different weights between the right and left side if equidistant from the centerline of the car, and a longitudinally parallel location?

I dont think they place much weight left or right, mostly because of body roll. It could be that they use slight weight differences left or right.

The ballast was from a metal, I believe it was called tungsten, but I am not sure, it weights the most per m² iic.

You'd want ballast on the parts of the car "suspended" by the suspension. That way you have less unsprung weight (the tyres and wheels are unsprung weight)

F1 teams generally use tungsten as a ballast, that is correct.

F1 test - Barcelona T02 - day 3

[chumma]

No pod winglets again.

Isn't lead the heaviest metal?

[raymondu999]

Isn't lead the heaviest metal?

Lead is about 11000+ kg/m^3 I think. Tungsten about 19000+ kg/m^3

I think tungsten is pretty much as dense as it gets. Platinum is denser - I think, but I don't think that's exactly financially sound
