Going to need a pump in there somewhere too I would have thought.
Why? Closed loop system. could also have a safety valve so that the first few mm of movement on the steering wheel in/out unlocks the system and the continued travel actuates the cylinders on the rack - that would avoid feedback to the steering wheel if the front wheels were impacted. I think I wouldn't want to use two cylinders on the rack though, just a single cylinder. Even if I used two, I would need to do something else mechanical to ensure they travel at equal pace (avoids one wheel toe'ing in/out faster than the other). If I'm going to tie together the movement of both rods mechanically in any case, might as well simplify and save weight and use a single cylinder.Possibly a scissor action could be employed, or twin racks crossing a central pinion to ensure both project and retract at the same rate?
In other news - good ol Grosjean, not even at the first race and already he's just binned his car!!

Definitely looking forward to the technology trickle-down so I can have this on my car.
Yep next big thing, I can see it now...Introducing the all new Mercedes Benz A180d AMG Line now with DAS.

I know it is usually with merit to give that guy a kick but lets be fair, he has completed over 140 laps and it's not like he was the first guy to spin out, just so happens he dropped the car closer to a barrier than the others.

For a change of topic, anyone feel like commenting on Russell and the Williams performance?
Have we seen enough to say they won't be adrift at the back anymore? Hopefully they can regularly fight for points. But significant if not massive improvements I would say. Encouraging.

Yes but this affects aero without changing the direction of the car; it's a controllable aero surface like drs.
They even banned mass dampers for being a controllable aero device, iirc.
I love innovations like this but I doubt it will make the grid, and if it does it will be banned after a couple of races for sure.
OK but people who are scrutineers, marshals, engineers up and down the pit lane and the FIA seem to be saying it's OK at the moment. They even banned mass dampers for being a controllable aero device, iirc.

Aero surfaces have to be fixed except DRS. If a part moves then consequential aero is allowed, this was tested with the dipping full lock. There is a restriction on moving things as a means of altering the aerodynamics, this is a consequence of moving to change toe, the damper was held to be moved in order to improve aero.

Sure but it's going to have a measurable aero benefit... and every fraction counts.Aero surfaces have to be fixed except DRS.

Time will tell, it's good to have something interesting to talk about anyhow.
So the FIA will have said it looks OK to them but is up to the other teams to explain why they think it's not.
Either way, as you say, it's an interesting topic!

The Renault mass damper was intended dampen sudden body movement in order to improve tyre contact patch over bumps and under braking like a road car shock absorber - giving a particular advantage when riding kerbs on cornering. The aero benefit of stabilising the car was secondary.Aero surfaces have to be fixed except DRS. If a part moves then consequential aero is allowed, this was tested with the dipping full lock.

Regardless of any aero benefit being dwarfed by the benefit of the variable geometry on mechanical drag and tyre wear if there is any aero benefit at all then the precedent is there to ban this.
As I said - it doesn't matter if Mercedes are up-talking it as a purely steering thing.
If the season starts with a runaway 1-2 for Merc with the others a lap behind then this will get banned in jig time, if for no reason other than I and many others won't be watching the subsequent races.

The key difference is that this is a mechanical system, that is fully under the control of the driver.Aero surfaces have to be fixed except DRS.
