Long time lurker here.. wanted to run something by you guys more knowledgeable than me.

Merc comes up with DAS at the front to change the toe angle of the front wheels.
Is is possible that they might have thought about something and is using something similar for the rear? I.e. rear wheel steering

They seem to be able to square off the corner and get on the accelerator quicker out of slow/sharp corners than the other teams.

Just my two cents.

Same reason why road cars do it, to increase part load efficiency.
With conventional load control (closing the throttle) the efficiency is low due to high throttling losses.
I suspect there are other advantages too, for example if the throttle doesn't close at part load then blow off valves (and all the associated disadvantages) are not required.

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.

Thank you! Awesome explanation.

I just cannot comprehend how the torque is being transmitted to the wheels? Where is the drivetrain?

It's the turquoise colored bar in the second pic. It used to be in a fairing with the rearward arm of the lower wishbone.
It's placing likely hasn't changed compared to last year but the rearward arm of the lower wishbone (yellow) is now decoupled from it and moved backwards and upwards.

The driveshaft is hidden in the carbon fibre sheath/fairing you see between the leading and trailing legs of the lower control arm. Covering of the driveshaft to reduce aerodynamic disturbance, is something that I think started about 2012 or so... Bare uncovered driveshafts used to be what was seen up to that time.

Actually, it was already done in the mid-2000s.

I thought so too but couldn't remember which car. Only could confirm in 2012.

Which car was it?

Mercedes will not have to use any tokens to remove DAS. I can't remember if it was here, or another thread, where someone was asking about that.

James Allison answers other technical questions, as well.

So much emphasis on team work and interpersonal. I like that, and I would feel good about if however menial my job at Mercedes. Get everyone in the family and keep them happy. Ferrari take note.

the first car with shrouded drive shafts was the Williams FW 16 (1994)

That and the no blame culture would really spark innovation, at least for me personally. They seem to also use the fail fast methodology in their work. With the no blame culture, failure is a very powerful learning tool.

Musk uses it and has progressed at many times the rate of companies like Boeing and even NASA. (different limits I know) If ti fails, you know parts of it do not work and which ones, not 'oh that wont work'
