Interesting analysis of the cars after testing by Heidfeld. It's sounding good for RBR again, promising for Ferrari as well, but oh dear on Virgin, doesn't sound promising.

QUOTE

Ferrari:

- Ferrari impressed more during the Jerez test.

- In Jerez the balance of the car was neutral, while in Barcelona the car had a slight tendency to understeer (this could be explained by the nature of the Barcelona track, which provokes understeer, while Jerez provokes oversteer.)

- The car has a lot of downforce.

- The car is stable in fast corners, which gives the drivers confidence.

- Sudden over- or understeer can be correctly easily by the drivers, even on high fuel.

Red Bull:

- Without looking at the lap times, the Red Bull looked to be the best car after its updates.

- It is almost frightening how good the Red Bull is.

- Red Bull has "sandbagged" in Barcelona; they haven't shown their full potential.

- He has seldom seen a car that is so well balanced, both is fast and slow corners.

- No other car has as much downforce in fast corners than the Red Bull.

- No other car brake as late and as long into the corners as the Red Bull.

- No other car is as good over the kerbs as the Red Bull.

- The Red Bull swinged the less on/after a bumpy track.

- They have worked a lot on the suspension and damping.

- The car has very little over- and understeer.

- Vettel and Webber can very easily drive the car on the limit.

McLaren:

- Before the updates the car was very nervous when driving over bumps.

- The car was very "pitch senstive"; it had extreme reactions under breaking and acceleration (tail stepping out and such).

- After the updates, the car was transformed in terms of handling.

- It over- and understeers a bit too much still.

- The car is tuned very stiff also in slow corners.

Sauber:

- The most stiffly tuned car.

- It jumps very much on uneven ground.

- Looks like a car that is difficult to drive.

- For Kobayashi, he always worries that he just flies of.

- But the car seems to be fast.

- Much will depend on whether Sauber can maintain that level.

Toro Rosso:

- Suprisingly good.

- The car oversteers a bit too much, but still driveable, due to which the tyres won't be destroyed.

Williams:

- Almsot in all aspects average; nowhere it is particularly good or particularly bad.

- Tuned very soft, which makes it good to drive in slow corners and over the kerbs, but slows it down in fast corners.

- The Williams is the car that rolls the most in turn 9, the fast righthander.

Renault:

- Improved a lot with it updates.

- The car is very nervous, or has to be driven nervous and aggressive.

- Suffers quite a lot from over- and understeer, but still controllable.

Force India:

- The car goes very well in fast corners.

- A bit nervous, but might be partly due to the aggressive driving style of Sutil

Newcomers:

- The balance of the Virgin is a disaster.

- Lotus looks much more balanced.

- Lotus has more downforce, but less grip and poor traction.

What amazing impressions - that is so, so interesting! It's like my entire Forza career described off-handedly.

Really good to read that stuff - so interested now! Renault sounds dreadful.

Fucking hell Leggard was embarassing durng that that BBC preview show, he really didn't k ow what what he was talking about and everytime he tried to raise a point he was blown down by brundle and DC, he really seemed out of his depth during that chat. Was hoping that Leggard would of been dropped after last years disaster but obviously not :)

Finally a shot of the HRT garage, they really are still building it.

It seems we might not have heard the last of McLaren's rear wing, the teams still seem to be complaining about it.

That young lad just let slip that

everybody's favourite Villeneuve

is commentating for the BBC on Sunday.

Also found out that the controversial McLaren rear wing staller seems to essentially just be an air hole that the driver covers or exposes with his knee, which means it gets around the rulebook. Genius.

Also Kobayashi's first exit from the garage was a lovely unruly fish-tail into the pit lane. I love this guy :)

That is pure fecking genius! Love the pic of Webber checking it out.

Id it just the little air scoop that sit in front of the driver to their left that is causing all the fuss? I need some sort of graphic showing me what that does when blocked to 'stall' the rear wing as I don't understand it at the moment.

Does it feed an internal tube that then feeds air to the rear wing or something?

Webber really was having a good look and poke around in the McLaren, can't blame him the perfect opportunity to do it.

Good to see the HRT finally make it out. Senna did seem to struggle with it and wasn't very fast, could just be a nervous first step into the unknown and was only an installation lap. Hopefully the second session will start to show us some more about where all the cars are and how close or far away the new teams really are.

Yes basically, with the driver being able to turn it on and off as he wants due to a hole in the tube by his leg. Good explanation of it on Scarbsf1's blog, he used to do technical analysis and illustrations for Autosport.

Cock, I would have told him in no uncertain terms to fuck off.

the interesting thing about both the Mclaren Wing & the Ferrari wheels is no other team can copy them this season.

The tub can't be changed once the season starts so no-one can add a hole, same with the wheels, they can't be changed. V Clever.

Why RBR sent Webber and not Vettel then, Webber would likely just laugh and tell them to fuck off as he has his head stuck in the cockpit. I like Liuzzi in the background, I can imagine an exchange like that was going on.

Also, Webber is a big bloke - Hamilton and Button would be able to bite his knees and not much else.....

How its done…

The snorkel on the top of the chassis feeds a duct passing down inside the footwell, its position is some where around the pedals, most probably it runs down alongside the brake pedal\footrest so as to avoid the mandatory padding inside the cockpit. This duct has a ‘hole’ in it to ‘cool’ the driver inside the cockpit. However the duct continues inside the chassis, past the fuel tank and up and over the airbox (probably passing by the hatch fitted high up on the engine cover), then through the shark fin and into the rear wing flap.

When the driver places his foot\leg over the ‘hole’ the flow is diverted into the rest of the duct and this feeds the slot on the rear wing flap. There is enough airflow through the convoluted duct to disrupt the airflow under the rear of the wing, effectively breaking up the flow around the wing. This is what F1 aerodynamicists term a ’stalled’ condition, although this is different to the term ’stall’ used in aeronautical aerodynamics. In this ’stalled’ state, the strong spiralling flows coming off the wing, that lead to the huge drag penalty a highly loaded F1 wing incurs, break up. With out these flows and their resulting drag penalty, the car is able to get to a higher top speed, by around 3-4kph.

When the driver is ready to brake for the next corner, he releases foot\leg and the airflow passes back into the cockpit and the rear wing flow reattaches, creating downforce and its attendant drag. In this format the car can lap normally with its wings delivering maximum downforce.

This set up is legal as the rear wing slot in itself is legal (used by McLaren, BMW Sauber last year). There is no specific working to prevent wing stalling in the rules. There are no moving aerodynamic parts, except perhaps for the drivers foot\leg. It’s a piece of interpretive genius, but perhaps as far removed from the spirit of the rules as you can get.

I think I'll be supporting Vettel and Liz this year

Red Bull's Sebastian Vettel, who has christened his 2010 car "Luscious Liz", is having his brakes changed after running wide. Did you know that last year, Vettel shunned the limelight by holidaying in Finland, in a caravan. I do not mean to be fickle but he is now my new favourite driver.

Yes practice, fuel loads and all that, but Sauber don't seem to be quite as high as expected. Hulkenberg seems to be doing a pretty good job so far though, looks like Williams have got two decent drivers finally.

The cars really are being thrown all over the place in the new section, could provide some excitement in the race if they don't get a proper handle on it.

Sauber's real strength (if indeed they have it) won't be seen until the final fifth of the race. When everyone else's tyres are dying on their arse.
