I see changes to the tail of the bodywork, where it meets the diffuser area, perhaps some radiator vents on the upper sides, different exhaust exits, different upper control arms (with some heat marks from exhausts too, so they've been art least straight line tested), and perhaps highly sculpted end plates for the rear wing. Hard to say for sure with just one, high contrast photo.

It looks like it was taken during unloading in Valencia. See the bleachers in the background.

normally the sidepods ended and did have a hole in the rear, this at least seems reduced, i see still a hole, but the seems to be some sort of horizontal plane a bit downwards. Although you can see alot on the pic alot of things are still hard to see, gonna check if i can show possible changes wit paint lol

EDIT: Image

Someone give clearance of what it is where the green arrow points to?

no not that one, it is in front of that under an suspension arm, it is a part of carbon wich starts at the side pods end, it isnt part of the floor, but rather part of the crahsbox, i dunno what it is.

Oh, sorry I see! I think it just maybe the sidepod but the light is reflecting oddly.

Not too sure how much has changed. The link are pictures from Germany, which seem to give clearer images than Hungary.

Is this a Valencia picture? There seem to be quite a few in the grandstand? Is that normal at this stage of the GP weekend?

According to the embedded jpeg data the picture was taken "2009-07-10 07:57". So it was taken before FP1 on Nürburgring...

I noticed that too...but they never ran anything like that at the ring, particularly in the race.

I think the camera lens is also decieving us slightly. The angle and the lens.

Once again I point out the pictures from their site which look pretty similar to this picture

Hey! Now Brawn are getting with the program! Note the barge boards along the sidepods!

I would only state that high drag really doesn't have to equal high downforce. While Brawn have had a good aero balance on the car from the beginning they also are the only team using that incredible cow catching, drag producing splitter design on the front. That is a centerpiece of their aero design. It would be interesting to see Brawn go more conventional on the splitter and add air straighteners to the outer corners of the sidepods like all the other teams and see where they wind up. If they don't, can you imagine how slow they will be at Spa and Monza?

If Brawn could scrape up the cash they should give it a try. IMO, this will be their best chance of a championship (either drivers or mfrs) for a good long time. If they fail this year they run the risk of low sponsorship monies in the future. They should go for it now.

I wouldn't be so hasty to say this. A few things come to mind...

How does the air get to where it is at the middle of the car? Generally it can be scooped up and over or it can be split R&L of the cockpit.

How do these differing approaches interact with the front wheels? The "wide nose scoop up and over" method creates a bit of a low pressure void under the chassis between the front wheels and this may help temper the high pressure wake area by the front brake ducts and smooth out the flow. Plus there is less air to split R&L under the driver's butt.

The F2001 was a car that had a very similar "slope nose" and it certainly wasn't a dog. Any "penalty" paid by the "drag inducing cow catcher" design can be reclaimed by a more efficient benefit of tempering the front wheel wake and calming the air as it meets the sidepod inlet area. There is also less air split R&L for better flow along the sides of the sidepods as it heads towards the rear wheels.

Aero is such a complicated matter that you can't just look at a design and say... "the cow catcher is drag inducing"... you have to take into account the whole length of the car. In the end such a design could have lower drag when all things are considered.

And finally, trap speed is indicative of more than just d/f or drag... it is indicative of a team's philosophical approach to the various track sectors, the length of the straights relative to the corner exit speed and much more. For instance, it is paradoxical but a high d/f approach of of the last turn at Barca actually results in a higher trap speed down the main straight than a low d/f set-up because the straight is not long enough for the drag penalty to offset the benefit of a higher exit speed off of the corner leading up to the straight.
