Germany Preview: new double-diffuser version for BMW
By BMW Sauber F1
July 3 2009
You always have a special attachment to your home race - in both good times and bad - and the BMW Sauber F1 Team is certainly looking forward to the German Grand Prix at the Nürburgring. Many chapters of success in BMW's motor sport history have been written at the circuit in the Eifel mountains, which is also used to put series-production cars through the most rigorous of testing.

Plus, the company has played its part in the extensive modifications carried out at the 'Ring.

Robert Kubica: "The Nürburgring is our home race. Even though this season has not gone well for us so far, there will be a lot of BMW Sauber F1 Team fans there crossing their fingers for us. This is just the right time to put in a strong performance and record a good result. However, I have to admit that the track itself is not one of my favourites. Having said that, it does have a big variety of corners and also opportunities to overtake. The best of these is in the first corner, where you can take various different lines. So I expect we'll see more passing moves again at the Nürburgring and enjoy an exciting race."

Nick Heidfeld: "It goes without saying that our verdict on the season at the half-way point is anything but positive. Especially when you compare our results so far with our aims going into the season. Of course I hope we will make improvements, and that's what everybody in the team is working to achieve.

"A lot of fans and fan club members traditionally come to my home race. That is something I really enjoy and it gives me an extra shot of motivation. I will once again be lining up for my home race with a special helmet design. This year it has been created by a fan on my website, and he will present me with the helmet before the start of practice on Friday.

"I have many happy memories of the Nürburgring. I went there a lot with my parents when I was a child and the 'Ring is only an hour away from my home town of Mönchengladbach. In winter we went sledging on the Hohe Acht slopes, I learnt to ride a bicycle at the Nürburgring and this was also where I sat in a kart for the first time - with a tyre and a blanket wedged behind my back so that I could reach the pedals.

"Since then I've competed in races at the 'Ring in Formula Ford, Formula 3 and Formula 3000 and celebrated many victories there. My best Nürburgring result in Formula One was in 2005 when I took pole position and finished second in the race itself.

"For me, the Nordschleife is the most sensational race track in the world. In April 2007 I drove our Formula One car on the circuit, which was just brilliant! It was amazing to turn off the grand-prix course onto the Nordschleife and drive along this huge race track all alone in front of all those people."

Mario Theissen, BMW Motorsport Director: "Going into the German Grand Prix, we cannot be happy with the season so far. After three successful years, this recent period has been the first set-back for our team - and is one we will overcome. After all, this is the same team in Munich and Hinwil that has delivered continuous improvements since the team was founded. We are all absolutely determined to start moving forwards again and I expect us to experience an upturn in form. It is certainly not easy to make up lost ground without the chance to do any testing, but that is what we're aiming to do. We are bringing a series of mechanical improvements to the Eifel mountains, as well as a further developed version of our double-decker diffuser.

"We feel a particular bond with the Nürburgring. Every series-produced BMW is tested on the Nordschleife circuit and BMW has celebrated some great successes in touring car racing here in the Eifel. The company also runs a Driver Training base here, as well as the BMW Lounge and the BMW Ring Taxi for the Nordschleife. Added to which, we are lending our name to the newly erected BMW M Power Tribüne grandstand on the start/finish straight."

Willy Rampf, Head of Engineering: "After our disappointing performance at Silverstone we have to turn things around at the Nürburgring. That's something we owe our many fans who always come to the race here. The characteristics of the Nürburgring mean the cars tend to understeer here. The key question is: how do you set the car up to stop it pushing over the front wheels too much? That can be resolved by an optimal aero balance combined with the corresponding mechanical set-up. We will be bringing a modified version of our double-decker diffuser to the Nürburgring, and we have also made improvements on the mechanical side. Much will doubtless depend on how successful we are at getting the tyres to work."

Re: Germany Preview: new double-diffuser version for BMW
It would be so funny if they brought some mechanical updates (suspension) and the car would suddenly click.

And Willy and Mario would still be scratching their heads in wonder what actually happened.

While it was actually a cleaning lady who spilled a coffee on keyboard,pressed some keys on active keaboard while wiping it and acdidentally changed few numbers on screen... hahaha...

Re: Germany Preview: new double-diffuser version for BMW
I'm afraid spilled coffee isn't going to be the answer, but who knows ? Nothing so far seems to be working well enough to give us a car that's even close to the boys out front. I'll cross my fingers again and await the outcome. Good Luck BMW.

At last mechanical changes. It should have been done straight after Monaco, but you know we're talking about BMW...

It's like with old polish joke about who invented the radio: Marconi or genius Russian Popov.

The joke went that "Popov invented the radio. And Marconi invented the radio that worked" ;-)

so BMW was bringing mechanical updates before.

now hopefully they will bring the updates that work smiling smiley

So.....are you saying we have Popov working in Hinwil?

I seem to recall hearing that during practice at Silverstone, the team realized the updates brought to Britain actually made the car worse. So, hopefully with the benifit of that on track 'testing', they must just do the opposite of those changes. In fact, perhaps the whole team needs a reverse psychology attitude: "Do the opposite of what we've been doing so far. Since what we've been doing dosen't work, logically, the opposite must be correct!". (Sm128)

Then we must give BMW another huge thumbs up, as we haven't seen slightest improvement since Monaco in terms of mech grip.

Re: Germany Preview: new double-diffuser version for BMW
I fear we cannot take the mech grip issue in islaion. We still lack of downforce too. I didn't say that they did introuce improvements on the mech said, I just said that there could have been even despite not apearing in press releases. I don't have enough info to judge properly any of the things above

Anyway, interesting quote from Nick, back in Silverstone:
We've certainly stepped up our pace of development, including the introduction of a new front wing that we had originally earmarked for the German GP, but the other teams have obviously come along with even better updates, so as a consequence, we don't seem to have made up any lost ground.

and

After a mediocre performance in qualifying, the race went pretty much as expected. Starting from 15th on the grid, the prospects are always going to be minimal. My best hope lay in a high-risk start, and that's exactly the approach I took. It was incredibly tight out there and I smashed my front wing. After that, of course, the aerodynamics were out of balance – we could see from the data coming in that I was desperately short of downforce. But essentially, I was relieved that the damage wasn't worse. We decided to wait until the planned pit stop before changing the part, so as not to lose any more time. When I got my new nosecone, I also fitted fresh tyres, but because of the regulations, they had to be the hard compound. The soft tyres were obviously the best choice this weekend, as the lap times in the previous stint had shown

I wish PR articles didn't filter ths kind of info, which ultimately is far more interesting than what we are used to.

Racing against the machine!

But in fact it was Tesla, so maybe if they buy Tesla from nvidia would be better than Albert XYz.

Re: Germany Preview: new double-diffuser version for BMW
Preoccupied or forgotten. That's the analysis of the front wing. I don't care if there's a 55 deck diffuser at the rear of the car, there has been ABSOLUTELY N O T H I N G done to the front wing.(Sm145) Oh silly me, I forgot, it's a total package.(Sm131) Wait! Did they change something. NOT.

[f1.gpupdate.net]

I happened to go to GP Update site and checked out the photos from Thursday. I looked at the wings from Brawn, Mclaren, Red Bull and others. It's is just beyond me how EVERY other team has sculpted the front wing while the lego front end still appears the same on the F1.09. Hell a pterodactyl has a more fluidly shaped wing. It's really nauseating how antiquated that booger looks hanging off the nose of the F1.09. I realize the whole car is krap, but for me there is nothing happening design wise that even comes close to matching the development pace of other teams. Hell, even the Force India wing appears more streamlined.

angry smiley Don't expect much in performance gains. For me, I'm going canoeing. I'll have more fun.

I don't know where they get their numbers, but seriously would it hurt to try a different end plate? The rest of the wing looks quite good, but then they just kill it. No wonder they lack downforce.
