A question to those who know more, when accelerating during qualifying...what should drivers press first, KERS or Rear Wing?

I had some earlier thoughts but one of Lewis remarks got me thinking, we may be trying something tricky there

Wing then kers

Bad assembly would cause too much vibration. It's probably deliberate. Then again it could be like the invisible bodywork from a couple of years ago..

Edit: translucent. Invisible parts were on the BMW...

Not that I would describe myself like that but surely KERS is usefull as soon their is enough grip, so pretty early during the acceleration phase, whereas the flattened rearwing only really matters at high speed.

So I'd go with KERS first.

KERS is limited, wing isn't - so the wing would presumably always be pressed asap. That doesn't answer your question, I know.

Don't think so. Accelerating out of a corner every ounce of downforce is useful for traction, and that initially matters more than less drag.

Press them both when you're not traction limited presumably.

I think the buttons are behind the wheel on both sides or infront.

4=KERS
20=DRS

Hamilton said on the bbc video hes doing the wing first, then kers.

Greater acceleration and thus benefit from kers that way. You can only use either of them once your not traction limited.

Of course, good point. I'm arguing from the (theoretical) premise that a driver has both at his disposal, and what he would use first in that case.

But it's really dependant on a lot of more things, which type of corner you come out of at which speed, etc.

I'd say out of Parabolica it's probably the wing first, because the car is already at high speed where less drag is more desirable than traction. Out of low-speed La Source I'd imagine the opposite, KERS first.

Really?

I think that is just worded badly, I assume you can use them when you like, but if your traction limited your likely to reduce traction further and be worse off for pressing the buttons.

You don't want the DRS deployed early on in traction as really you want the downforce to aid traction.

this is what I thought, KERS is useful when there is grip...you can use it to power through the traction phase quickly.

while if you release the rear wing too early, you may lose traction because of the loss of downforce and get all wobbly

But Hamilton did say they push the rear wing first.

So I wonder if they've found a way to activate the rear wing slowly, only for qualifying....so that if pressed in early stages of acceleration, you dont lose the downforce all at once, but slowly through the traction phase and it is fully open when traction is needed no more (i.e. when everyone else is just activating theirs). This way you might be able to press the rear wing before KERS.

Obviously, there is a huge chance im fundamentally wrong and it doesnt work like that

If not, I wonder if any team has thought about this.

Also I wonder if in some fast corners you normally take flatout e.g. 130R, while using the DRS it may not be possible.

Is it possible for teams to have a half DRS setting specially for those corners where instead of using the whole thing, you just use the minimum required for the corner?

Oh and by the way in 09, KERs was most useful accelerating from a slow exit unto a long straight...so I doubt anyone will be using in after 130R or so, except to overtake.

What he said! If you use either whilst traction limited, you'll just spin the wheels up and cause yourself more trouble.

Yep, that's what I'm thinking too.

I would've thought RW first then KERS. Otherwise KERS boost would face more resistance thus less efficient and energy wasted.
Like hitting a brick wall per se.

Nope. KERS is traction limited whereas the wing is lateral grip limited.

edit: to be accurate, wing is also traction limited whilst in the corner, however as soon as the corner starts to straighten out, the wing can be used as traction will no longer be a problem whereas for KERS it could still be a problem, especially in slower corners.

isnt the wing unlimited in practise and qualy? so you want tobe popping the wing as much as you can, and kers being limited your going to use that in select places only. activation time might be the reason if the wing is slow to move to low drag then its more a preporation.
what was the old kers disable/traction speed? was it 60kph or 60mph?

I thing it's first wing, then KERS. I think less drag makes it easier to accelerate. Of course, on the other hand, more downforce gives more traction.

I think we just need to look where KERS was used in 2009 (acceleration, re-starts, etc...) and where F-duct was used last year (straights) and we already know the answer.

Look, it's very simple, I have no idea what Vettel is whining about:

Special Moves:
Teleport: D, Up
Diving Kick: D + HK (in air)
Hat Throw: B, F, LP (Use Up and D to control the hat)
Whirlwind Spin: Up, Up, LK (keep pressing LK to spin longer)
Head butt: HP (close)
Finishing Moves:
Fatality 1: F, F, F, LK (sweep)
Fatality 2: Hold LP, B, F, release LP (far) - SG
Fatality 2: Hold LP, B, F, release LP (far), control the hat with Up and D so that it hits your opponents neck - A, PC, S32, SS, SN, PSX, PS2, XB, GC, PSP
Friendship: B, B, B, D, HK
Babality: B, B, F, F, HK
Stage: F, F, F, HP (close)

Hamilton said Wing then KERS, but even he had to think about it and check with Jenson.

The cars usually have enough traction so the wing should be able to be activated fairly early. But this is a question that will be answered during FP's I guess.

If both were limited, KERS first.

KERS is mainly used to accelerate away from slow corners, so you gain speed all the way down the straight, it´s used the earlier, the better. Low wing is more useful when drag is high, so it if was time-limited, it would be used on the final part of straights, the later, the better.

But as wing is unlimited, both at the same time: as soon as you can.

I properly lolled.

I wonder what combination might get you 'Nude Raider' on the timing screen.

The DRS is behind the wheel on the F150 so that picture is not accurate. What's the problem with using both devices at the same time?
