2011 Brazilian Grand Prix Preview
- The 2011 Formula 1 World Championship draws to a close in Brazil as the Autodromo Jose Carlos Pace stages the 19th and final Grand Prix of the season
- The 4.309 km track, situated in Interlagos, is quick and one of a few to run anti-clockwise on the calendar. The bumpy surface and the constant ups and downs mean that the cars and the drivers are put through their paces. The potential unstable weather conditions may also add to the excitement surrounding one of the most popular races on the calendar and last event of the 2011 season.
- Pirelli has nominated its PZero medium (prime) and soft (options) for this race.
- There are two strategies, one which is a higher downforce setting where the middle of the lap is better optimised, and the other one is a lower downforce setting which is better for the long straight up the hill through to turn one and then the second straight down to turn four. That will cause a little bit of work on the wing level, both from a strategic and also the lap time point of view

Pirelli tyres , KERS , DRS and ban of multiple deck diffusers are the main reasons for the significant differences observed in the chart above .
data source : Brembo
Preview – Indian Grand Prix
The Buddh International Circuit in Greater Noida is located about 50 kilometres south east of New Delhi in the northern state of Uttar Pradesh
Track length : 5,137 km
Corners : 16
downforce level : fairly high
Pirelli tyres : Hard/soft
Estimated average speed : 235 km/h
Estimated top spedd : 320 km/h
Expected lap time : 1 min , 27 sec
Seating capacity : around 150.000
The track is a combination of slow corners and high-speed straights which flow into each other. The altitude difference is extreme, rather like in Spa or Turkey, which will give the driving an additional element. Incidentally, teams are expecting the track to have the second highest average speed of the season after Monza.

Top speed is significantly increased in 2011 due to KERS and DRS resulting in greater braking power as well . Canada is very tough on brakes and 2011 race was even more crucial bringing brake components to the limit . Traditionally teams enlarge their brake ducts in Montreal to ensure cooling and reliability .

Monaco is a unique circuit hold on public streets with the track lined by barriers .It combines turns of different nature like very low speed and tight turns , medium speed S turns and hairpins . Cars are set on greater camber and highest possible downforce .Once again Pirelli tyres are responsible for the differences shown in the braking analysis chart below , reflected upon the much lower mechanical grip provided .

To date Spa will be the lowest downforce level the teams have run, with a lap of slightly over seven kilometres it is the longest track of the season . A lot will depend on the weather conditions, because they are very unpredictable. As always in Spa, teams have to monitor the weather closely over the weekend. The circuit itself is very popular with the drivers, and a great place to engineer a car. The track is primarily high speed with long straights and well known corners. The Pirelli tyres are the soft and the medium compounds. Teams are aware from Silverstone that the soft tyre works well with the high speed corners, but teams have some work to do with the medium compound

Analogous observations to China and Malaysia are noticed in Turkey like the greater 2011 top speed at long straights due to KERS and DRS and lower speed in slow corners because of lower grip provided by Pirelli tyres compared to Bridgestone used last season . Pirelli tyres lower grip is supported also on other strong facts seen on regular base, like the greater stopping distance, the increase in braking time with a significant decrease in maximum deceleration .

2011 Hungarian Grand Prix Preview – Hungaroring
The Hungaroring is a long established circuit which the teams know well. It’s a fairly low speed track with lots of medium and low speed corners, but all of them are quite flowing rather than stop start. It’s one of the high downforce circuits during the year. Not as high as Monaco, but certainly higher than the majority of circuits . It will be an interesting event because teams will have the soft and super soft tyre compounds, which they haven’t run since Canada. These are tyres which will work very well there. It is usually fairly hot there, so the ambient and track temperatures play a role in the way the tyres work and how you have to operate your car. It’s also a track which has never been particularly easy for overtaking, so qualifying and race strategy will probably play quite an important part. If the temperatures are high, and tyre degradation is also high we could well see a number of different strategies being played out.

2011 German Grand Prix Preview – Nürburgring
The Nürburgring is a technical track which is characterised by medium speed levels and a good mix of slow and fast corners. The main challenge will be the weather in the Eifel Mountains which is quite unpredictable just like at Silverstone . Mechanical set-up is very important here, because of the understeering-nature of this race track and the nature of the corners.

Sinopec circuit features long straights followed with violent sharp brakings, fast turns that require perfect car balance and many slow and medium speed corners . The most violent braking point is at kurve 8 where cars brake from320 km/hand seventh gear to only 68 and first gear loosing 2649 KW of kinetic energy . Lower 2011 entry speed in tight kurves 3 , 4 , 5 , 6 , 7 , 8 , 9 indicates the worse grip level provided by Pirelli tyres compared to Bridgestone . On the contrary higher 2011 entry speed in medium kurve 1 reveals the higher amount of aerodynamic downforce generated by 2011 cars body permitting a faster travel through the corner .

Once again it is clear from the chart above that 2011 cars suffer much greater deceleration energy due to KERS and DRS . However in low speed corner 2 , which follows a short stretch , the stopping distance is significantly increased, but the opposite outcome should be expected as both Maximum deceleration and braking time are by great percentage increased ( despite the greater top speed at the end of the stretch ) ! . This observation is unique and to the opposite trend compared to car behavior on the rest corners. A logical explanation is hidden on tyre compound differences between this season Pirelli and last season Bridgetone tyres, showing that Pirelli ones offer less mechanical grip leading to longer stopping distances. Another fact indicating less mechanical grip provided by Pirelli tyres is the lower speed entering a corner after a stretch ( final speed in the chart above ) .

Melbourne track is full of demanding braking zones where disc brakes suffer hard pressures and high ware, the surface is quite bumpy particularly in the braking zones and very slippery at the start of the race weekend as it is used as public roads , the surface of which is full of small debris . Nevertheless grip gradually increases during weekend as the track is rubberized.

The 2011 cars suffer significantly higher braking pressure compared to last season as they are equipped with the new DRS ( drag reduction system ) and boosted with extra energy from KERS comeback and thus being able to achieve significant higher top speed . Mc Laren even covered both the front and rear brake ducts with wire netting to prevent debris from entering inside the braking components , understanding the significance of steady and non fading out braking performance .

Pit Stop strategy in Sepang
Pirelli predicts a possible four or three pit stop strategy in Sepang circuit due to higher track temperatures and more rapid tyre degradation than was experienced in Melbourne .
