2017 F1 general testing thread

[Shakeman]

Good chat with Newey on Ted's notebook at 9.50.

His take on T wings, a lot of visual change for small aero change.

Surely the converse is true once DRS is active and the downforce is removed off the rear wing?

They clearly have some suspension trick as here is the RB13 coming thru a corner with the huge rake turned back on.

I am not so sure if this topic isn´t a bit overrated. The cars produce a very high amount of downforce at higher speeds, that would have them pushed down anyways. There is something going on, but it´s natural to have diving cars at high speeds.

DRS is wide open and the bum is squatting, if anything the bum should raise with less down force pushing the rear downwards.

Looks like Force india may have done it again! Produced a good car on a shoe string.

Currently closer to Ferrari than Williams.

Yesterday Massa did 1:22.07, Perez did 1:23.7. Williams are looking really strong and reliable with the merc engine, if RB don't show up they should be going in the season as 3rd fastest after Mercedes and Ferrari. Mclaren on the other side are looking like 2001-2002 Arrows both visually and relative-performance wise.

Dont get ahead of your self guys, at the end of testing they'll probably all be sub 1.20's.

Its slightly off topic, but is Ted's notebook only available on YouTube now? I don't see any of it available for non Sky subscribers (like in previous years). I was looking for it last night and this morning

as speed increases, the car produces both rear and front downforce so car would be overall lowered but rake conserved. moreover when DRS open the front dowonforce should prevail so you should obtain the opposite of what you see in rb

Indeed, that rear squat under full DRS is mightily impressive!

I wonder if the perceived 'effect' of exteme squat and rake are being exaggerated by the photographers perspective on both the main straight and in the corner. Difficult to imagine CofG movement that effectively makes the car 'wheelie' when DRS is active.

I think 1.19 will be possible.

Rake would never be preserved as relatively the front of the car is much stiffer sprung than the rear and the downforce and weight is rear biased.

[Vasconia]

No i just want them to run a bit faster than 5 secs off pace....say 2 secs.

No until they can make a good amount of laps just to gain somo confidence. If they can make 70-90 laps today perhaps they will increase the performance for tomorrow.

the fact that weight is rear biased has no impact for the case considered here.
while of course the relative stiffness of the spring has an impact: since I don't know these data as you do, my reasoning was general

[PhillipM]

It does when the photo's you're looking at are right after a bump in the track.

I hope they have a planned testing program. A few technical issues will not hurt if they are well planned. They must be able to complete each stage and be methodical rather increasing the performance of the engine abruptly.
However if things get murkier with every testing day and if there is no substantial no of laps in then it means there is serious problem. Honda might have failed again in 2017.

Surely no one thinks the shark fin looks worse than the isolated t-wing, right?

(FYI I think both should stay and are interesting)
