Hamilton 106 laps only in the morning session...what the hell!! Closing in on 2 race distances in 4 hours...wow!

These guys have so much endurance...unbelievable! Even a robot's battery would have ended by now...

Im pretty sure it's not to get heat into the tires, because if you use it for added scrub, only the surface of the tire will heat up, causing graining. Its the same when a car doesn't have enough downforce and slides too much, it also causes graining.

It must be for less tire resistance on straights

Heat must be come from somewhere and they will use it only for gaining enough heat on the tyres, may be just for one straith. That not cause anything bad but cold tyre can cause many thing

Although I don’t think heat is the main issue it HAS to reduce/increase scrubbing if it’s changing the toe of the wheels. Which HAS to change how much temps the tyre create.

It could also be a way of removing heat too. It depends on which side of the coin you’re looking at. I’m not certain tyre heat is the main reason for it though it could be loads of things. It could be to reduce tyre wear in general, resistance, etc.

That is true, but I still think its reducing scrub, for lower resistance, and as some say maybe even work in conjunction with POU to change ride height. Maybe thats why their POU is that extreme

If they are lifting the front they are also likely dropping the rear, or at least, changing the pitch of the entire car to make it more slippery.

34.1 Every team must provide the FIA technical delegate with a suspension set-up sheet for both of their cars before each of them leaves the pit lane for the first time during qualifying practice session.

so the toe angle in Mercedes' setup sheet will be: "it varies"

They won't be terribly concerned with graining they are just priming for a qualy lap.

Something a bit different (though still involves HAM/Merc)


Mostly, over the 1st and 3nd stint, Hamilton is over a second faster than Sainz Jr. and does a roughly similar, or longer stint. But that 2nd stint is an interesting comparison, as after 15 laps HAM is only as fast as SAI, who remains quite consistent there and can go five more at the same pace. Of course, 2nd day running and all, but, I found it interesting. Maybe HAM's first lap was a bit too hot?

[Tamburello]

Williams already many tenths inside their best qualy time in Barcelona last year.

10.2 Suspension geometry :
10.2.1 With the steering wheel fixed, the position of each wheel centre and the orientation of its
rotation axis must be completely and uniquely defined by a function of its principally
vertical suspension travel, save only for the effects of reasonable compliance which does
not intentionally provide further degrees of freedom.

So the rules say fixed steering wheel but don't mention what fixed means. I think the spirit of the rules is the wheel should be only rotated and translation shouldn't be in its degrees of freedom.

Furthermore if they deem this legal what's stopping the teams from implementing a system with more than 2 options? They could shift the wheel like a manual gearbox and have a different steering profile for each corner.

Nothing, and since the POU are outlawed next year, there's not a lot of point to running the system next year.

So teams will have to decide if it is worth slapping on to the car or not. Similar to the Double Diffuser and F-Duct, it's something you want to design into the car, not slap on the car.

One is "auto" the other isn't. Maybe someone should explain that to Cyril?
