On mi je sledeci na tapetu

Ali samo jos ovo da dodam na ovom topiku:

 

 

Mislim da su prilicno rizikovali sa ovakvim airboxom, ali je na bocnim usisnicima prilicno vidljivo zbog cega su to odradili. Neverovatno podseceni sa prednje strane, minijaturni, suzeni. Nivo detalja je vec fantastican na ovom bolidu. Deflektori ispred usisnika, pod, zadnji deo koji je vertikalnim deflektorima vezan za pod, vertikalna krilca pored retrovizora. Ludilo od detalja.

 

Ova cuda sa bocne strane airboxa su pretpostavljam kamere za promotivnu voznju?

To 'Force, majstoru!

 

I meni je ovo omiljeni deo sezone, jer se davim u tehničkim pikanterijama.

 

U pravu si, svi su se pošteno oznojili u aero tunelima. Meni se čini da na delu gledamo mini revoluciju dizajna, sa "zategnutim" guzama, "nepostojećim" menjačima  a la Vilijams i bokovima na nož.

 

Ako airbox ne radi i ne "hrani" pogon, Ferari uzima titulu. Ali ako su "usta" (airbox) dovoljno halapljiva, će bidne opet gangbang...

Tech analysis: The 15 key changes on the Mercedes W07

 

Giorgio Piola and Matt Somerfield detail the key design tweaks that Mercedes has made with its W07 design as it aims to continue its dominance of Formula 1.

Mercedes had already teased images of its new 2016 F1 car during a 'promotional' day at Silverstone on Friday when Nico Rosberg and Lewis Hamilton completed almost 100km between them.

But on Sunday, the team finally delivered some clearer pictures of the car that it hopes will deliver it a third consecutive F1 championship double.

Although some of the most interesting aspects of the new design may not yet have been revealed – like the final nose design – there are some notable clear differences to the car compared to the W06.

 

 

1. The nose shown on the images released by Mercedes on Sunday is unchanged from the W06, and appears at first glance to be different to that run in the Silverstone shakedown earlier this week. We cannot rule out a new design being used when the car hits the track.

2. Like last season the steering arm has been placed in-line with the lower wishbone, creating less blockage and increasing the surface area of the two components. This allows them to condition the airflow in unison.

3. A large vanity panel fills the upper wedge at the front of the bulkhead, allowing easy access to make set-up changes, whilst the size of the panel means the introduction of an 'S' duct cannot be ruled out.

4. The horizontal leading edge slat, that forms part of the vertical sidepod airflow conditioner has been raised when compared with the W06.

The vortex generator now sits underneath the slat, rather than on top, and defines the difference in shape of the outboard section of the sidepod.

Like the Ferrari SF15-T bodywork used from Barcelona onwards in 2015, Mercedes has created a notch which changes the way in which the airflow moves around the sidepod.

5. The mirror stalks have been mounted closer to the cockpit, rather than on the side, which has allowed them to place a new much taller fin behind it.

6. The new, enlarged airbox combines the main compressor feed with the two 'ears' used on the W05 and infrequently on the W06 (like the below image shows from the Mexican GP for example). 

 

7. Interestingly the airbox is lent back at an angle, which should allow airflow to follow the sculpting around the underside of it.

Whilst unusually a single centreline lifting spar is loop shaped rather than a simple straight edge.

8. The engine cover is a little more bulbous, accounting for the additional pipework associated with the enlarged airbox.

 

 

9. The sidepod cooling outlets have been shrunk, proving what a wonderful job they've done with cooling, considering they're expecting an uplift in power.

10. In line with the changes at #9, the rear undercut is now much more pronounced, maximising airflow in the coke bottle region.

 11. Mercedes has increased the number of slots ahead of the rear tyre, reminiscent of Toro Rosso's approach in 2015 (see below), as it looks to marginalise the effects of tyre squirt.

 

The Mercedes AMG F1 W07 has similar cuts in front of rear tyres introduced by Toro Rosso in Austria together with new rear suspension

12. The twin vertical floor strake arrangement used in the past has been retained.

13. The detached hoop run by Mercedes during the 2015 season seems to have been improved upon.

14. A twin wastegate arrangement will be run by Mercedes, echoing what we saw with the Williams FW38 launch.

15. A simple change, but the Y150 Winglet (Monkey Seat) now features an additional slot, which should assist in manipulating the exhaust plume, improving balance and performance.

Mercedes to run new nose on third F1 test day

Mercedes executive director Paddy Lowe has confirmed that the W07 will run with a new specification of nose on the third day of the pre-season Barcelona Formula 1 test.

Toto Wolff previously alluded to the reigning champion outfit running some “unusual” parts on its 2016 contender this week, after making big progress on the opening day of the test.

That was immediately in evidence on Tuesday, as the team introduced a radical new bargeboard design on the car in which Nico Rosberg completed 172 laps.

Now, the team is set to introduce a new nose design on Wednesday, as revealed by Lowe in a keynote speech in Barcelona.

“Tomorrow we will have a new nose,” he said. “That’s typical of the sport at this stage; we’re bringing lots of new parts to the car on a daily basis - all the way up to the first races.”

'Floor W'

Lowe added that a new floor design that was introduced on Tuesday was deliberately given a code name unrelated to its purpose.

“[We used] a new floor today, which we code-named Floor W,” he said. “It caused a lot of excitement in the pitlane this morning."

“We code name things internally, so that they are completely unrelated to what they are.

“It means that when people talk about them, nobody really understands what it means, unless they are closely involved.”

CONMAN JAILED AFTER BIZARRE ‘MERCEDES F1 CHIEF’ DECEPTION

 

A fantasist conman has been jailed this week for posing as a Formula One chief at reigning champion Mercedes following thousands of pounds worth of fraud and theft, and racking up huge hotel bills.

Warwick Crown Court heard how Stuart Howatson, 37, falsely claimed he was chief operations officer at the Mercedes-Benz Formula One team in 2014 while he negotiated deals for expensive computer equipment and systems, and stayed in hotels across the counties of Warwickshire and Worcestershire, running up sizable room bills.

In total, he pled guilty to 12 charges of fraud and one of theft, for stealing over £1,400 from a man whom he offered a fake job with Mercedes.

The court was told how Howatson posed as an F1 chief in deals for security systems worth over $234,000, computer software systems worth almost £20,000 and a web security system costing almost £800,000 – although his lawyer pointed out he personally would not have financially benefited from them.

He was sentenced to two years in jail.

Personality disorders

Howatson's lawyer also claimed that his client suffered from a "variety of personality disorders".

Howatson had previously been jailed in 2010 for convincing a couple in Spain to allow him to stay in their villa under the pretense he had the funds to buy it, and claiming he was a senior figure in the Metropolitan Police.

Although Howatson attended court at the start of his hearing, he was admitted to hospital on the day he was due to be sentenced. The court was told he was "apparently suicidal," and later learned he was under the care of a mental health crisis team following an overdose. This delayed the case for over a week.

During sentencing at Coventry Crown Court, recorder Derek Sweeting QC told Howatson, whose jail term had been reduced by a third because of his guilty pleas, "You carried off the deception with a great deal of persuasive skill.

"The victims have commented on the lengths you went to. The real purpose of the fraud was to make you feel better and more powerful, and to carry through the persona of being chief operations officer for the Mercedes-Benz racing team."

When contacted for a response to the conviction, the Mercedes F1 team stated, "Mercedes-Benz GP Ltd has worked closely with Warwickshire Police on this matter and would like to thank them for their support in bringing it to a conclusion. Mr Howatson fraudulently used the company name and wrongly declared himself to be an authorized person acting for the company. We regret the damage and trouble this behaviour caused to third parties, in addition to how it impaired our own business. We are pleased that this matter has now been brought to a close."

In Australia two weeks ago, both silver cars were beaten off the grid by the Ferraris, after the Maranello team proved to have best mastered the new rules limiting drivers to the use of a single clutch lever for race starts.

 

"Daimler is making a new clutch for us," team boss Toto Wolff told Germany's Auto Bild. "We have asked the research department for help."

 

"We don't know exactly when it will be ready," he added, referring to "weeks or months".

[Rad-oh-yeah?]

Mercedes on Sunday rubbished suggestions Lewis Hamilton's horror run of bad luck so far in 2016 may be a conspiracy.

As Nico Rosberg turned his six-race winning streak into an almost unprecedented seven at Sochi, some were daring to wonder if reigning champion Hamilton's continuing reliability problems have been more than just bad luck.

"This (suggestion) is b------t," team chairman Niki Lauda told British television Sky, after Hamilton had to start the race tenth following an engine problem identical to the one in China two weeks ago.

Team boss Toto Wolff said heads are being scratched.

"We have eight engines in circulation, thousands of test kilometres have been driven, but this defect has occurred only twice and always in the same car," he told Auto Motor und Sport.

It is believed Mercedes is not ruling out a chassis problem that is causing the glitch, but the conspiracy theorists suggest that Hamilton's in-race water leak just as he was catching Rosberg is a further sign of a deliberate plot.

Wolff calls those sorts of people "lunatics".

"The last thing we would do is sabotage Hamilton -- he's a great friend to us and we are letting him down."

Indeed, Mercedes demonstrated its valiant efforts to minimise the damage to Hamilton's weekend in Russia after qualifying.

A crucial part - preventing a grid penalty - was flown to Russia overnight aboard a specially chartered jet, reportedly at a cost of some $43,000. The team then enlisted the help of Bernie Ecclestone to ensure it cleared customs and arrived at the track at 2am.

Further fuel for the conspiracy theorists, however, is that Hamilton's car is this year being serviced by mechanics who formerly worked on Rosberg's side of the garage.

"All of a sudden we swapped for no apparent reason," a downbeat Hamilton recalled on Sunday.

"But that's not the reason we're having these issues. Don't jump the gun," the triple world champion, now 43 points down in the championship, added.

"It (favouritism) has not happened in the last three years and I have no reason to think it's happening now."

Lauda also hit back at the conspiracy theories.

"I hate this talk because we have eleven hundred people all trying their best for both cars. These are simple, human mistakes," he said.

Mercedes: A Letter to the Fans

To the fans,

We returned from Russia on Monday with mixed emotions. On the one side, filled with pride at another one-two finish – a rare achievement in the ultra-competitive world of Formula One and something to be savoured but never taken lightly. On the other, pained by a stressful weekend – both behind the wheel, on the pit wall, in the garage, back at the factories and for all of you watching at home.

We have seen a lot of frustration aired online after the mechanical issues experienced in Sochi. We share those same emotions – but for us, it goes far beyond frustration. For those watching at home, a Grand Prix weekend starts on a Thursday morning and ends on Sunday night. A bad result might hurt for a few hours afterwards – but then life moves on. For more than one thousand people at Brackley and Brixworth, however, this is our life. These men and women pour their blood, sweat and tears into racing, day in, day out – often working around the clock and spending weeks at a time away from loved ones. They do so through passion for their work, loyalty to their team-mates and a desire to be the best.

The success we have enjoyed in recent times has not come about by accident. To paraphrase Mr Toto Wolff, we have worked our a**es off to get where we are today – and we have done so as a team. The faces you see at the track are only the tip of the iceberg – but they are a perfect example of just what this represents. They don’t just perform pit-stops together. They travel, share rooms, eat meals, construct garages, build cars, re-build broken cars, kit spares and pack down tonnes of freight – together. They sweat, strain, laugh, cry, shout, scream, celebrate, and commiserate – together. And, as one of our own often says, they win and lose – together. We have the best guys and girls in the world, doing an awesome job, week in and week out – and they do it for the team. Not for one driver or the other – but for each other. There is no ‘A’ or ‘B’ team here. Every single member of the crew has earned their right to be counted among the elite of their trade – and have sacrificed much to do so.

What happened in Sochi showed the world just what a team working in unison is capable of. We were baffled and gutted by the repeat MGU-H failure on Lewis’ car in qualifying. But we kept calm, gathered our thoughts and sprung into action. It took a monumental effort from a significant number of people back in the UK and in Russia to fly spare parts out to the track, fit them to the spare Power Unit by working through the night and make sure Lewis could start from P10 on Sunday without having broken parc fermé. This made Sunday all the more stressful for each of us. But, in the end, we were relieved just to get both cars to the flag.

Shortly after his pit stop, we saw some alarming behaviour from Nico’s MGU-K. We spent a number of laps reassuring him that he had a good gap over Lewis and could ease off before the FIA gave us the all-clear to tell him to switch to a setting that would control the issue. At the wheel, Nico wouldn’t have had any inkling of the stress on the pit-wall. When he put in the fastest lap on the penultimate lap of the race, he was still in that ‘safe’ setting – demonstrating just how much pace the car had last weekend.

Not long after Nico’s issue arose, we started to see the water pressure falling on Lewis’ car. At the time, he was pushing hard to catch Nico and pull away from Kimi – posting several purple lap times in the process. Again, we needed to await confirmation from the FIA of what we could tell him via the radio. After several calls asking him to take it easy, the all-clear came to let him know that he was losing water pressure. With zero – yes, zero! – water pressure remaining for the last 16 laps, the job he did to nurse the car home and still retain second place was truly remarkable. He had to keep the car as cool as possible to avoid damaging the engine whilst also keeping Kimi at a safe distance, which was no mean feat. We genuinely aren’t sure by what miracle the car limped across the line – but we’re certainly not going to complain!

Ultimately, none of this changes the fact that we have not met our own expectations in terms of reliability so far this season. Performance-wise we are right on the money – with a points haul just two shy of what we had managed by the same stage in 2015. But there is work to be done. Our goal is not simply to be fast but bulletproof too. Not just to manage problems but to understand them, fix them and ensure they are not repeated. We are working tirelessly to do just that and will continue to do so every step of the way. But there are no guarantees. This is a mechanical sport, balancing on the knife edge of performance and endurance. You have to push the boundaries and failures can happen.

And then, there’s the bigger picture. Here we sit, picking apart a weekend of various challenges – both on and off track. But look at the result. We should not simply be grateful to see both cars crossed the line but proud and humbled after a team result which quite literally could not have been stronger, thanks to the amazing efforts of the guys and girls in the factories, in the engineering offices, on the pit wall, in the garage and, of course, in the cockpit.

So, four races down, 17 to go. And, from what we’ve seen so far, it’s going to be one heck of a rollercoaster. There will be highs and lows, good day and bad days, successes and defeats. But, through all of this, we stand united as a team – just as we always have. To those who stand with us, we thank you. And to the rest – the haters, the naysayers, the conspirators… if we can convince even half of you of what we really stand for, we’ll consider that a battle well won.

Together, #WeAreW07
Together, #WeAreTheSilverArrows

Mercedes' technical problems in recent races are a result of the growing threat of Formula 1 rival Ferrari, according to team chief Toto Wolff.

The world champion team was very reliable in pre-season testing but has encountered a series of problems during race weekends, particularly on Lewis Hamilton's car. In Russian Grand Prix qualifying, Hamilton suffered an identical power unit problem to the one he suffered in China and required parts to be flown in overnight. In the race, his chase of team-mate Nico Rosberg ended when he encountered a water pressure problem while Rosberg had to back off because of an issue on the MGU-K.

Speaking in a video on the Mercedes YouTube channel, team boss Wolff said: "With the regulations staying stable, you want to extract every single bit of benefit out of the engine and therefore it becomes more difficult. Ferrari has made a huge step over the winter and this is why we are pushing boundaries and sometimes when you reach the limits, you just need to find out. And this is where we are."

Wolff said the causes of the two problems were not yet evident but working groups have been set up to get to the bottom of them.

"Because we are pushing so hard, we had an issue on Nico's car where on the MGU-K, we saw some overtorque, which is quite a worrying signal because it might break," he said. "With the current regulations, you are not really allowed to tell the driver, so it was quite difficult to manage that. On Lewis' car, we had a cracked carbon pipe which looks like it being a problem on the quality of the pipe itself. We need to look at it. We are trying to analyze and find the root causes for the problems and it's not evident. It's a complex issue. There are a couple of project groups looking at each of the possible problems and I'm sure we will overcome these and come out on top of understanding the issues."

LETTER WAS A THANK YOU TO FANS

Mercedes wrote an open letter to its fans on Wednesday, responding to suggestions on social media that Rosberg is favored over Hamilton.

"This was a letter to our real fans," Wolff said. "What you could see on social media is that they support us, they suffer with us.

"They argue for our cause and that was so nice, so we felt we wanted to give an insight as to what was happening and how we felt and thank them for their support. We want to be transparent in our communication. There is nothing we are hiding. This is why the letter was a good example and a good way of sharing our feelings and thanking for support of our fans."

[Rad-oh-yeah?]

Lewis Hamilton has moved to reassure his fans that he still has faith in the Mercedes team and his mechanics, despite a troubled start to the 2016 season.

Hamilton used Facebook to put his thoughts across, saying that he trusted his guys “1000%.

His full message is as follows: “I want you to know how grateful I am for all of your support. I’d like to ask that you please trust in my team, as I do. This is my family. These guys have been the greatest, hardest working people for me, and that is why I am now 3x World Champion. Please don’t put any more thought into my team doing anything unjust towards me, and understand that it would be in no one’s best interest for that to be the case.

“We’ve had the best 3 years together, and whilst it’s not going to plan right now, all will unfold in its own time. I trust these guys 1000% and my mechanics are incredible, the best in the business. I respect them so please do the same. They are the guys that are going to make winning this championship possible. Thank you once again.”

Toto nezadovoljan vidljivoscu Mercedesa tokom TV prenosa, smatra da ih FOM bojkotuje zbog dominacije:
 

Toto Wolff has vowed to raise with Bernie Ecclestone the issue of Mercedes' underrepresentation on television, despite its ongoing dominance of F1.

The German marque's F1 chief claims that, as Nico Rosberg won all four grands prix so far in 2016, the silver cars were not featured prominently on the FOM-controlled broadcasts, particularly in Russia recently.

"It is a difficult thing and we are having discussions to make our point," Wolff is quoted by The Sun newspaper.

The issue is not new, after Mercedes' one-two at Suzuka last year attracted only five of the broadcasted 90 minutes of television coverage.

Bernie Ecclestone denied he ordered the blackout as punishment for Mercedes refusing to supply Red Bull with engines, explaining that focusing only on the lead cars is "boring".

"Lewis and Mercedes are just too dominant for their own good at the moment," he said at the time.

Now, Wolff is unhappy about FOM's coverage of the recent Russian grand prix.

"We thought we didn't have the exposure of the race cars that we thought we should have, but I guess it is a difficult discussion," he said.

"I think the difficulty for Bernie is that he has multiple clients. There are the sponsors on the car, the sponsors on the track, the TV and the fans who want to see spectacular racing and the main protagonist who is leading the race and that needs to be balanced out," added Wolff.
