Inače ova fora sa menjanjem strana guma je Mercedesu provaljena na onom tajnom testiranju u Barseloni.

[Jimmy Kowalski]

Zar nisu govorili tada da su gume bile neobelezene?

[alpiner]

100km je voženo na ovogodišnjim gumama, ali nije ni to bitno, važno je to što su ljudi iz Pirellia pitali inženjere u Mercedesu zašto ne koriste foru i ovi su od tada počeli da je koriste. Leva i desna strana su bile obeležene.

Malo statistike.Vozači:Vettel nikada nije pobedio na domaćem GP-u. Ima samo jedno postolje iz 2009. Uvek se kvalifikovao i završavao trku u top10Webber je ovde prvi put osvojio pol i pobedio 2009. Poslednje tri godine uvek je završavao na podijumu.Alosno ima impresivan učinak u Nemačkoj. Pobeđivao je na obe staze. Hockenheim: 2005, '10, '12 i Nurburgring: 2005, '07 koje su vožene kao GP Evrope. Od kada je u Ferrariu, trku je uvek završavao kao prvi ili drugi i uvek se kvalifikovao u top4.Massa je bio u top5 na poslednje četiri trke u Dojču. Ima tri podijuma 2005. '06, i '09. Njabolja kvalifikacijona pozicija mu je treće mesto.Interesantno je da su oba vozača Ferraria završili sve svoje trke u Nemačkoj. Alonso-16, a Massa-14.Button nema ovde neke značajnije reezultate. Jedno treće mesto '04, poslednji put je ovde osvojio bod još sa Brawn-om kao peti. Na Q ima loš skor protiv timskog kolege sa 2-8Kimi ima samo jedan podijum, a odustao je čak pet puta. Poslednji put je završio trku 2006. Bio je nadomak pobede 2005, ali mu je spektakularno otpao točak u poslednjem krugu.Hamilton ima pobedu u Hockenheimu 2008. i Nurburgringu pre dve godine.Timovi:Red Bull je u Nemačkoj od 2009. uvek zavšavao sa oba vozača u bodovimaOvo je za Ferrari po broju pobeda najuspešnija zemlja u kojoj su vozili F1 trke. Imaju 21 pobedu(Italija 18, Francuska 17)Mclaren je osvojio osam pobeda.Mercedes ima samo jedno postolje i pobedu još davne 1954. sa Fangiom.Williams je do sada imao deset podiuma i tri pobede, poslednju sa Ralfom pre deset godina.

Od vesti kao značajnije treba izdvojiti odluku da na testiranja u Silverstoneu 17-19 jula timovi mogu da dođu sa standardnom vozačkom postavom. Prvobitno je planirano da ovo bude rezervisano samo za mlade vozače.Pirelli na ova testiranja dolazi sa novim gumama koje imaju oblik i konstrukciju prošlogodišnjih, a mešavinu iz 2013. Ove gume će se koristiti od Hungaroringa.Vozači prete bojkotom ako opet bude pucanja guma, ali ovo je malo verovatno obzirom da su ugovorima stegnuti u predelu međunožja. Ovde bi pre mogli da reaguju timovi, ali i oni su ucenjeni od sponzoraFormula 1 drivers pledge to boycott German GP if tyre dramas returnFormula 1 drivers have warned that they will boycott the German Grand Prix if there is any repeat of the Silverstone tyre problems over the weekend.Following a meeting of the Grand Prix Drivers' Association (GPDA) in the Nurburgring paddock on Thursday night, the body issued a strongly worded statement making clear its unhappiness at the current situation in F1.Although Pirelli is adamant that the Kevlar-belted tyres it has brought to the Nurburgring will not suffer a repeat of the dramatic failures that blighted the race at Silverstone, the GPDA is not fully satisfied.It has made it clear that if there are problems with the tyres at any point during the German Grand Prix weekend, then its members will withdraw.The statement said: "The drivers of the Grand Prix Drivers' Association wish to express their deepest concerns about the events that took place at Silverstone."We trust that the changes made to the tyres will have the desired results and that similar problems will not occur during the German GP weekend."We are ready to drive our cars to the limit, as we always do, and as it is expected by our teams, sponsors and fans."However, the drivers have decided that, if similar problems should manifest themselves during the German GP, we shall immediately withdraw from the event, as this avoidable problem with the tyres endangers again the lives of drivers, marshals and fans."Four drivers suffered blow-outs during the British GP - with Pirelli blaming a combination of low tyre pressures, adverse camber, tyre swapping and kerbs for the problems.The new Kevlar-belted tyres used in the German GP will be for this event only(do sada su korišćeni metalni), with a new specification - featuring 2012 construction and '13 compounds - being used from the Hungarian Grand Prix.http://www.autosport...rce=mostpopular

Još malo o gumamaF1 tyre tech analysis: camber, pressures and why reverse tyres?Pirelli's post-British Grand Prix analysis identified several factors that contributed to its tyre failures - reversing tyres, low pressures and extreme camber angles.AUTOSPORT's technical writer Craig Scarborough explains all.REVERSING TYRESReversing tyres - running them on the opposite side to the one they are designed for - is not a new trick but has come and gone with different tyre suppliers.Tyre dramas will mean changesPirelli tyres are asymmetric, requiring the outer face of the tyre is mounted on the outer face of the wheel, but they are not strictly directional, meaning that a reversed tyre will work.It is common practice for teams to reverse a worn set of tyres and the outer shoulder of the tyre is still the outer shoulder when reversed and there does not appear to be a performance advantage.Instead, it is about teams aiming to get more use from worn sets because tyres on one side of the car will wear more the other.Because of the asymmetric design of the steel belt in the pre-Nurburgring tyres, there is the problem that a reversed tyre has the joint between its two ends pointing in the opposite direction, making it easier for it to separate if there is a problem with the tyre's shoulder, as happened at Silverstone.TYRE PRESSURESTyre pressure is a key tuning aid, with stability, traction and warm-up characteristics all affected.At Silverstone, teams ran lower pressures, perhaps below Pirelli's recommended settings.This makes the tyre move about more as it is supported less by internal air pressure and with the 2013 tyres having stiffer shoulders and more pliable sidewalls, they will deform more and place greater stresses on the shoulder join.CAMBER ANGLEThis is the angle of the wheel and tyre assembly relative to the vertical and, at a standstill, the front camber angle is usually around 3.5 degrees from vertical with the rear set at between zero and one degree.Sergio Perez's tyre damage, British GP 2013, SilverstoneAs the top of the tyre tilts inwards towards the centre of the car, this measurement is negative and the inner shoulder will bear more of the load.As the car moves around the track, the suspension will vary these camber angles by several degrees.Such an increase in camber increases the stresses on the tyres inside the shoulder.At Silverstone, the drivers were putting tyres inside the kerb to straightline certain corners, meaning the loads on the inner shoulder of the tyre would be far higher than usual.Any cuts or imperfections in the tyres could lead to the catastrophic failures seen during the race.Currently, these set-up tricks remain unregulated (although Pirelli has asked for this to change as soon as possible) so teams are free to run the tyres outside Pirelli's recommendations in pursuit of performance.http://www.autosport...rce=mostpopular

Krenula je glasina kako bivši tehnički direktor Lotusa James Allison prelazi u Ferrari.Štampa u Španiji piše da je odbio ponudu Mclarena da bude zamena za Paddy Lowea i da je odabrao Maranelo. Jako talentovan inženjer, završio je dinamiku fluida na Kembridžu. Tokom Šumaherovih zlatnih godina u Ferrariu bio je glavni aerodinamičar na njegovom bolidu.

Raikkonen says Lotus stronger, but rules out poleKimi Raikkonen is optimistic that the Lotus will prove more suited to the Nurburgring than it was to Silverstone this weekend, but does not expect to be in the pole fight.After a muted British Grand Prix, from which he still might have taken second had his strategy been different, Raikkonen was in the top five in both Friday sessions in Germany."It is more or less the same car as we had last week. I think part of it is for sure the circuit, it is a bit better [for Lotus]," said Raikkonen."It is a more high downforce circuit and probably suits us better than the low downforce, and also it is a long time since we used the soft tyres on a normal race circuit, which was at Shanghai. For some reason they seem to be a bit better for us."He said a top-six spot is the most Lotus can expect for qualifying, but is more optimistic for the race."The front four cars will be very fast in qualifying, but the race is always a different story," Raikkonen said."I think the weather will get much hotter, so that should only help us."If we can put our cars in the top six tomorrow then that is a very good starting place, then we have to see where we end up in the race."We have to work on the cars a bit to get it a bit better - the long runs felt bad but the car wasn't with the right set-up."I think you can expect more or less similar to what we have done in previous races, where we qualified and we were a bit better in the race."http://www.autosport...t.php/id/108577

Tesko ce Kimi i do podijuma, bojim se. Za ocekivati je da prva dva reda na startu zauzmu Mercedesi i Red Bull i da na tim pozicijama i ostanu. U Mercu su zadovoljni tempom u duzem stintu i potrosnjom guma, pa bi trebalo da bude zanimljiva borba za pobedu..

[alpiner]

Ja ću biti zadovoljan ako Kimi završi u top5 obzirom da se Mercedes ubacio u igru na vrhu. U Mercedesu se žale na meku gumu, ali ona nije od odlučujućeg faktora zato što se neće voziti više od 10 krugova.

[Jimmy Kowalski]

Da, neka bude best of the rest.. To je maksimum u ovom trenutku..
