2011 Brazilian Grand Prix Preview


Circuit
Autodromo José Carlos Pace / 4.309 km
Race distance
71 laps / 305.909 km
Schedule
Qualifying and race 14:00 hrs local time (16:00 hrs GMT)
  Date:  25th-27th November
  •                 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

Preview – Abu Dhabi Grand Prix


  11th-13th November
Circuit
Race distance
55 laps / 305.355 km
Schedule
Qualifying 17:00 hrs, Race 17:00 hrs local time (13:00 hrs GMT)

 James Key, Technical Director (Sauber) :

Abu Dhabi was a memorable race last year when the championship was won there. One factor in that race was overtaking was difficult. That’s something we have to bear in mind this year, although DRS should support overtaking. But certainly it will be an interesting race where the strategy could play a role. We go there with the soft and medium tyres, which is the same combination we had in Suzuka. The track itself has got three very distinct sectors. The first one is a short sector with medium to high speed corners. The second is dominated by a couple of chicanes and two long straights, so there low drag and efficiency are important. The third sector requires high downforce for the slow to medium speed corners. Therefore getting the downforce level right and balance it for this track is an important part of Friday’s work. The car will be the same specification we had in India. We have, however, several new approaches to some of the mechanical set-up, coming off the back of a difficult qualifying in India, where we just couldn’t get the tyres to work. We think Abu Dhabi will be better for this, but nevertheless we looked into this in detail and we will go with some fresh ideas to make sure we’ve got everything covered if tyres are the problem. In the race in India we got back to where we should be competition wise, and we clearly also need to be at that level in qualifying in Abu Dhabi.”
Colin Kolles, Team Principal (HRT) : “We had quite an encouraging weekend in India, showing a much better pace than our direct rivals, and we are looking forward to Abu Dhabi to round it off. However, we have to keep our feet on the ground, focus on ourselves and do our job properly. If we do, I am sure we can hope for a good result at the Yas Marina Circuit. The event was fantastic last year, a really impressive facility with great atmosphere. For the first time, Daniel will drive at a racetrack that he has already been before with a Formula 1 as he was one of the young drivers participating in the post-race test. He actually had an impressive performance and, although this time will be a different situation, I am confident that this can allow him to kick the weekend off from a better position. Tonio will be back in the car this weekend and he is highly motivated. I am sure that we will see an interesting Grand Prix. The team’s performance has improved th roughout the season and the last races have been particularly positive for us. We certainly are in a much better position than we were eight months ago and I hope that we will continue this way until the end”.

Preview – Indian Grand Prix

October 21, 2011 1 comment

17th of 19 Rounds of the FIA Formula One World Championship, 28-30 October 2011

 

 

The Buddh International Circuit in Greater Noida is located about 50 kilometres south east of New Delhi in the northern state of Uttar Pradesh

Circuit
Buddh International Circuit / 5.125 km
Race distance
60 laps / 307.249 km
Schedule
Qualifying 14:00 hrs, Race 15:00 hrs local time (08:30/09:30 hrs GMT)

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.

Preview – Korean Grand Prix


 

Track location : Yeongam,South Jeolla , 400 kilometres south of Seoul and near the port city of Mokpo

  • Circuit Length   5,621  kms ( 3.492 mi)
  • Circuit Turns  23
  • Circuit Direction anti-clockwise

 

Lap record :   1.50.257 , Fernando Alonso – Ferrari 2010

 

 

 

Technical view with James Key, Technical Director of Sauber :
We have got some quite good memories of Korea from last year. It’s obviously a neat track. It took a bit of work with the very low grip levels on the very fresh tarmac, but, once the track rubbered in, it turned out to be a good circuit which the drivers liked. It seemed to be quite technical with two long straights, but then you’ve got the relatively winding sector towards the end of the lap, and then some high speed corners before the last straight. So it’s a really good mix of corner speeds that will probably require quite a different set-up compared to what we were using in Suzuka. Last year it was extremely wet, therefore we haven’t experienced a full race distance in the dry, so we don’t fully know what to expect from the tyres, which will be the super soft and the soft compounds. We don’t know how green the track will be in the beginning, so we’ll have to see the track evolution during the weekend and try to allow for that. Concerning the car, we will continue to develop the package we introduced in Suzuka. We’ll have some small additional follow up development items for introduction in Korea. I hope we can carry on the momentum we found in Suzuka.

Japanese Grand Prix Preview

September 30, 2011 1 comment

  After passing through Singapore, the Formula 1 World Championship stays in Asia for the Japanese Grand Prix. The 15th race of the season is also the second in a five race stint in the Asian continent. Suzuka is a unique race track as it crosses over itself in the shape of an eight meaning that it is the only circuit in the championship to run both clockwise and anti-clockwise during a lap. It is a quick and technical track where downforce and tyre conservation are important elements.One of the standout features at Suzuka is the 130R, a 130 metre radius turn taken at speeds of over 300 km/h.
Pirelli have chosen the P Zero White medium and the P Zero Yellow soft tyres for the Japanese Grand Prix.

     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 .

2011 Belgian Grand Prix Preview


12th of 19 Rounds of the FIA Formula One World Championship, 26-28 August 2011

Circuit
Spa-Francorchamps / 7.004 km
Race distance
44 laps / 308.052 km
Schedule
Qualifying and Race at 14:00 hrs local time (12:00 hrs GMT)

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 circuit braking analysis


Melbourne street circuit main characteristics :

Length Km : 5.303 m
Number of laps:

58

Type of brakings: hard
Number of brakings:

8

Downforce Level: High
Tyre Compounds: Soft/hard
Time spent under braking per lap:

11

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 .

James Key, Technical Director:
“Montreal will be the first track this year where slightly lower drag levels tend to be beneficial, although this will depend on the grip of the track surface and the tyres, which are an unknown. Last year we had some interesting strategies developing because tyre degradation was quite high. It’s not clear if this will also be the case with the Pirelli tyres. It’s a circuit with quite a few low speed chicanes and kerbs, so mechanical grip, good traction and kerbing is quite critical. It’s also a track which is one of the hardest on braking, therefore brake stability, brake cooling and general use of the brake system will be something to watch out for. The track in Montreal is usually good for overtaking, and with KERS, DRS and the tyre characteristic it should definitely offer opportunities for this. For the first time this year we will have two DRS zones which will also add to this. Our car will have some modifications to adapt to a lower drag setting, but we will tune that according to the track grip and the conditions. We hope for a good race weekend again. Monaco was a race with ups and downs, with Kamui bringing us ten points but with Sergio not competing after his accident in qualifying. When I spoke to him he sounded very well and was looking forward to getting back to work. We are looking forward to having him back in the car.”

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 .
