Mercedes W11

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.

Cosworth was just an engine supplier not also the dominant team (that just copied their car for another team as well that is now also top 3 to say the least, might be top 2 as well).
Don't forget this is the customer car period, so a large chunk of the grid ran duplicate or almost duplicate cars, or one or two season old models.

I was just about to point this out as well. It reminded me a bit of Indy Car before they went to a single supplier chassis.

I'm sure you guys have seen it before, but I've just noticed this for myself.

The modern car is a feast of detail. Simply eye watering detail.

Zibby, the car doesn't touch the kerbs at all during 0:22 and 0:35. At 1:00 there's a pretty clear separation denoting the sound from the car and the sound from the kerbs.
The farting noises is the engine tuning system working its magic. It is similar to the Honda step-firing. Cutting some cylinders or adjusting of timing to fire a bit late, i think respectively saves fuel or used to quick spool (blow down energy). It is not considered traction control because it doesn't use a feedback loop from the wheel speed sensors to do this. It is baked into the engine map from the garage.
I noticed the car doing this honda-like noise in winter testing, but was told it was already doing this from before.

Must be a more subtle sound then, are you listening with headphones?

Can somebody explain this please?

What is the difference between this (W11)

And this (W10)

See where the leading leg of the lower control arm is? Right beside the driveshaft. It must pushed rearward. The trailing leg is also far back.

There is also that it has been raised relative to the previous one, I think. That's helped free up space above the diffuser to help airflow.

One of the few things where it's immediately clear what it's purpose is and where you can see how it improves performance.

I haven't had time to check it, but I was sure that traction control systems were outlawed by requiring a kind of unique growing function between the pedal position and the power output (or demand).
Was I wrong?

Cylinder skipping still delivers whatever torque the driver requests. The difference to normal firing is that there are fewer cylinders operating at higher load. The mean torque at the wheel is the same.

It also looks like it turned into a multi-link suspension. The lower control arm is actually two separate arms now.

Most likely fuels savings and reduced heat.
