Mercedes W11

Yes. But note what I said.
The rulesare in black and white. Steering in on chapter. Suspension in another.

This is how Mercedes could not be touched this year.

[bosyber]

Yep, that's the way I see it too, and what seems to be the informed consensus, as that's the only way Merc and the FIA would be so sure it was legal for this year.

Interesting details on the DAS joint

[PlatinumZealot]

McLaren had this sort of joint in the 2000's. It was for aerodynamic reasons, to change the pitch the steering arm in the air.

[El Scorchio]

Apparently just been confirmed by the FIA that DAS will be outside of the rules in 2021.

Edit: which actually makes what someone said earlier completely true. Great piece of strategy to put the other teams in a situation right now, where they potentially waste time developing a dead end to keep up this year but sacrifice next year, or kiss this year goodbye.

But it can be argued that it's not steering.

Mario Isola did an interview which more or less confirmed a thought that I had based on the movement of the front wheels: the system changes both camber and toe.

While the system may decrease rolling resistance slightly due to reduced toe, I think the real advantage will be that it can get the full contact patch of the tire in contact with the road while in a straight line. Hence you can work heat into the full width of the tire before you hit the brakes or begin to corner.

Presumably it will also reduce wear on the inner portion of the tire, but I don't think the effect will nearly as large as one would expect because the system is only used for a small portion of each lap.

But if it changes also the camber then the system would not comply with articles 10.2.1 and 10.2.3, right?

and also.. tech rules define wheels as part of the suspension system
so 2 chapters but wheels are described in both

Is this really just for DAS system. My opinion is that this oval thing changes height of the car when cornering. It is present on most cars nowdays.

Wouldn't the camber change become more negative though due to the castor angle? In my mind they're actually reducing the contact patch when they adjust to the neutral toe angle down the straight.

Could this all just be a Mercedes flex/red herring? We have so much money/resources, here's this piece of tech that might give us what- .5 sec around a given lap, and even if that's a big maybe, making other teams think about that just for one year could throw a spanner in their 2021 plans.

Maybe you’re right any comparison pictures from 2019 would give us an idea of the differences in packaging
