RB trying to say DAS was part of the suspension system, hence a moveable
part, hence illegal.
If they had won, tyre carcasses are part of the suspension system and
are moveable - they rotate - and should also be illegal!!
According to Karun Chandok Mercedes were only using DAS during out laps.
He speculates that it's used to warm up the front tyres which was a
problem with the 2019 car. So seemingly it's not used to gain any lap
time except indirectly by bringing the fronts up to temperature before
a hot lap.
Surely there must be more to it than that. It will be interesting to see if
they use it during the race.
There is no doubt that there's more to it.
The normal setup for an F1 car is with the front wheels toed out just
slightly (for those who don't know, that means that each tire points a
little outward from the centre line of the car). This is a compromise
setting where it gains you speed in the corners by creating some
additional front grip (particularly in slow corners) but it costs you a
small amount of friction on the straights which both slows the car
slightly and wears the front tires more quickly because the the tires
run at a slight angle to straight ahead.
Mercedes system will definitely let the car go just a little faster on
the straight and probably means that they can use more toe-out to
enhance cornering than other teams can because of what it would cost
them in straight line speed.
So it allows a car which is more optimized for cornering AND more
optimized for straight line running.
The ability to deliberately run the tires toed out when you want to
build heat in them is just a nice bonus.
