Newey-Designed Rain Machines

I had been assuming that the diffuser-three would be the stars of the wet weather conditions as they'd naturally have a downforce advantage, especially at the rear where getting the power down is crucial in the wet. But Toyota wasn't all that special, Williams weren't either, and most surprisingly, the kings of 2009, BrawnGP weren't even able to keep up.
Button mentioned trouble keeping heat in the tires, and this is what I'm thinking is their problem. Its seems as if BrawnGP's biggest advantage is their race pace, and maybe they aren't so hot in cooler conditions and in heating up their tires, kinda like how Ferrari were last year? Is it that simple? Would this also mean that the Newey cars, while good in qualifying or the wet, will be less stellar in normal race conditions over longer stints?

It's too soon to tell yet, but the next few races should indicate whether Brawn can maintain the advantage they started the season with.
It looks as though Red Bull, McLaren and Renault have all moved closer in performance, and with the diffuser issue settled it's down to a development race.

This. The balance changes from aero generated mechanical grip to just pure mechanical grip.

Can it be as simple as good mechanical grip? Newey is noted as one of the great 'aerodynamicists', so you'd think that his cars would be more aero-orientated, right? Or is that a false assumption?

Which would definitely a valuable thing to have in the wet. I remember the Toro Rossos always being right up there in the speed traps when it was raining, while still putting in impressive times. People say that mechanical grip is so important in the wet, but I think we're seeing this year that aerodynamics play a huge role as well.Originally posted by Boing 2
in his williams days the talk was all about how his cars were more aero efficient than the rest, generating the same downforce for less drag, this allowed them to run bigger wing angles without losing top speed to their rivals.
This is kinda what I was thinking, that maybe there's simply more to it than simple mechanical grip, especially from a designer who is more noted for his aerodynamic proficiencies.

Of course aero is important, but the slower one goes the more important mechanical grip becomes.

I dont have the lap by lap timetables here but if I recall correctly Vettel was especially fast after the restart, he opened up quite a gap there until Button's pace gradually picked up and the lap-times got closer. I assume this was because of tyre temperature, as a car's ability to keep heat in the tyres becomes especially apparent during a safety car period. So I think that's THE main reason, just a guess though.

It think that though Newey is touted as great aerodynamicist, it misses the complete picture that Newey has on a car. He always included great mechanical solutions as well, only he was always one to go to the extreme, resulting often in breakages.
However, let that not fool you from the fact that he surely builts great mechanical grip into his cars.

I think what he means is that a fast race pace depends on low tyre wear, which means maintaining a constant tyre temperature, no overheating or having alot of weight on the rear suspension to wear the tyres. You keep a light approach to the tyre usage and don't stress them over a dry race stint.
In the rain you need the opposite. You need alot of tyre temperature to generate grip given that the rain is constantly cooling the tyres. If your mechanical setup is light on the tyres in the dry then in the wet then you might struggle to generate the extra heat needed to maintain a decent race pace in the wet.

With the lower speeds associated with the wet, you'd spend less time at the cut off speeds for the double decker diffusers to work in my theory, leading to a disproportionate reduction in downforce and tyre temperature.
Well, just some random thinking, that may or may not make some sense to someone.

In which case I think we should give them a little time to work on the problem before condemning them. Todays race was only the second time the Brawn has run in the wet, and the first time was during a race too. What they need is for it to rain on a Friday to allow them to experiment a bit and find out how to make best use of the wet tyre. So far they've basically had to guess the setup with no real data to base it on.

The Brawn is very gentle on its tyres. Look at the last stint in Melbourne, Vettel destroyed his softs which allowed Kubica to reel him in. Jenson went even longer on them, ok not pushing as hard, but had no tyre issues whatsoever. Jensons style, IMO, works the tyres less also which was to his detriment today, similar to Aus 06 where he famously had no tyre temps.
Jenson mentioned in the PC that the Red Bull had loads more grip in the fast corners. Im inclined to think that is aero grip rather than mechanical.
Im not disagreeing ofcourse...

Wings, on the other hand, still work. So if Brawn has better undercar downforce, but RedBull gets more downforce from its wing package, they may just work better in the rain.

We've seen this since 2007, where Vettel and Webber and even Liuzzi were able to put the Red Bulls and Toro Rossos to good use in the rain.

Whats this based on? I seem to remember many great wet weather performances in these cars. I think you are trying to blame occasional poor wet weather driving on the car.

I never perceived Newey cars as being bad in the rain as much as Schumacher Sr. making them (and everyone else) look slow.

I think the Newey's concept of "Upper Body Efficiency" makes the RB5 especially good in the wet. Newey knew that the rules this year meant much less downforce generated under the car (even with a DDD diffuser), so he focused on above-car downforce. The frontal area of the RB5 is quite small, which leads to low drag. He's also got a DD front wing with slot gaps, similar to last year's car and the wing on the current McLaren, for lots of efficient front downforce. However, this downforce is only good if you can get similar downforce in the rear. If not, you'll just get oversteer at high speed. The height of the rear suspension allows the sidepods to shrink down much lower than other cars, allowing less drag and cleaner air-flow under the rear wing to those mini-wings above the diffuser (around the crash structure). Also, the shark-fin engine cover helps keep the rear stable during braking and cornering (so much so that Raikonnen couldn't get the rear to behave as he wanted last year, so he opted to not use the fin, whereas Filipe's braking and turn-in style was able to benefit).
This is concept of generating downforce with the surface-airflow, as far as I understand, why Newey's car can be so quick without the DDD. However, since diffuser downforce is much less draggy, Newey had to compensate with less frontal area and small sidepods go really low towards the rear.
And whereas the pull-rod rear suspension isn't really... independent, it seems to be really good for traction. The better your mechanical traction, the quicker your downforce kicks in. And the quicker you can go, the better you can keep temperature in the brakes etc. So it seems like a good car in the wet. But as we saw in Australia, the car absolutely destroyed the super-softs, whereas the Brawns were able to maintain good pace over more laps.

How many wet races did Schumacher win over a Newey car? At least a dozen. From the top of my mind:
- 1992 - Spa;
- 1993 - Interlagos, Donington, Suzuka (Senna, obviously)
- 1995 - Nurbugring, Spa, Suzuka;
- 1996 - Barcelona;
- 1997 - Monaco, Spa;
- 1998 - Argentina, Silverstone;
- 2000 - Nurburgring, Canada, Indy, Suzuka
- 2001 - Sepang;
- 2002 - Silverstone;
- 2003 - Indy;
- 2006 - China, etc...
Of course these races weren't all wet and drenched like China was yesterday and the tyre war played a huge role back in the days. But the records give no indication that his cars are special for the wet.

When they got out of their cars Jensen went up to Vettel and Webber and said "your car has loads of downforce", which would imply he thinks the Red bull was fast in the fast corners which means aero grip, not mechanical.
I dont think the wet tyres need to be kept warm, it wears them out faster, so I doubt it's mechanical grip.

Yea, Steve Matchett was saying something similar on WindTunnel last night. And that makes a lot of sense as to why the Brawn's weren't as fast as the Red Bulls, despite probably having a better aero package overall for normal conditions.Originally posted by Neophiliac
I suspect it's a matter of generating downforce the right way. It could be that the diffusers don't work very well in the wet - the airflow under the car basically being disrupted by all that water. This may be why Jense is complaining about the car working differently in wet conditions and not to his liking.
Wings, on the other hand, still work. So if Brawn has better undercar downforce, but RedBull gets more downforce from its wing package, they may just work better in the rain.
