Right, but I still believe the R29 nose to be a decay...ooops, I mean decoy.

Seriously, is Jerez a "power-track"? Could Renault and Red Bull's speed be down to Renault doing a better job than expected on the upgraded engine, anyone?

Jerez isn't a power circuit. It is a mechanical grip and balance circuit. Low down torque is quite useful too.

I know we've got a limited number of cars on the track, but has anyone seen any driver comments regarding the wake/tow coming off a leading car and what they expect in terms of overtaking?

Whilst it may look like a joke, Renault are serious about that nose and the only way it won't be on the car come the first race will be if they've made a huge mistake. It's not a decoy.

*SIGH* this topic done a bender. The ones we should be talking about are the ones inboard. The ones on the outside of the wheels have been there for weeks, keep up. The ones on the inside are new. The ones on the outside may have been for measuring something in test last year, but this year they are aero devices - they have clearly managed the maximum width regulation but reducing the front track width. The ones on the inside again clearly have a similar aero function to the outboard version and have been integrated into the brake ducts to make them legal.

take care now, bye bye then.

Their function has already been covered dude.

Aside from increasing front end downforce from the front wing, I suppose an additional benefit will be less complicated flow for the front suspension to straighten out, maybe improving its effectiveness a little.

Anyone have any idea why mac is still running 08 spec rear wings?

I read Hamilton was fastest today of all 09 cars but the pics today show him running with the wider wing.

They are waiting on their definitive 2009 wing to arrive from the wind tunnel, so are using the 2008 wing as an interim measure to put realistic loads on the car for reliability checks.

He might not have been running it all day. :)

In a french traduction of a quote from Kovaleinen, it was mentioned that the team is waiting for it's high downforce version of the 2009 wing. Maybe the traduction was bad, but the way I read it meant they already have a 2009 wing (which we have seen), but aren't interested to test with it (as they are probably in preparation for medium to high DF tracks, of which the first half of the year is filled).

If true it means their 2008 wing is currently used to simulate the highest DF level of 2009, which coul explain (partially) their stunning pace at Jerez.

Hi again,
First McLaren were using an '08 wing apparently "as a precaution" and now we hear it's because the wings not built. Don't believe everything you hear.
I did mention some time ago that they are trying to get as near as they can to '08 rear end downforce, and to use it as a known level.
They will alter the rear of the car (including diffuser) using an '08 wing. They will then know if an alteration has improved or not.
If they used an '09 wing they would have to take the '09 wing into account, making it harder to determine the actual improvement as the '09 wing is not fully proven.
I highly suspect diffuser testing is going on.

All the teams have to seriously look into the Toyota - Williams style rear diffuser.

Who will be the first to bring it to a race will give us an idea of design, manufacturing and development capacity of the teams ovfer the season.

Well, F1 is not a design contest, and it is important that all your car works well, not just a diffuser. In recent times many bright innovations came from "lesser" teams but it was grands who really made it work... or ultimately discarded.

These items will NOT be on the car come Melbourne as they are A/ Illegal & B/ for testing purposes to measure various Tyre parameters, same as they were last year!

I agree with you that sometimes ideas that 'lesser' teams come up with are quickly copied by others. But the fact that Adrian Newey get 10 million a year would suggest that someone thinks the 'best design' this year might just win some races.

If they are there solely to measure tyre parameters... why are there none on the back tyres?

If its an illegal test only part - why not run it completely across the tyre (bridging from outside rim to inside rim) so you can measure the full tyre temperature range?

Your not going to get an awful lot of data on temperature across the contact patch when measuring from the side.




While admittedly I did not follow testing very closely last year, I do not recall there being any wheel shrouds on the inside of the wheels last year - thats the ones we are talking about here.
