WHAT’S THE STORY?

The recently-constructed Buddh International Circuit represents brand new territory for all the teams as well as Pirelli. With the track never having been used before, Pirelli has opted for a tyre nomination that should cover every eventuality, with the P Zero Silver hard tyre – making its final appearance of the season – alongside the P Zero Yellow soft tyre. Contrary to convention though, the softer tyre has been nominated as the prime choice in India with the harder tyre as the option. This means that the teams will have more of the softer tyres than the harder tyres at their disposal during free practice on Friday: the first opportunity that the teams will have to run on the 5.137-kilometre track. In addition the teams will also get an extra set of soft tyres on Friday, allowing them to maximise their running and provide Pirelli with some valuable information for the future.

Collecting as much data as possible prior to qualifying and the race will be a priority for everybody, but the track is likely to be ‘green’ and slippery, as it has never been used before. Just as was the case at the last race in Korea, there is likely to be considerable circuit evolution over the course of the weekend as more rubber gets laid down and the amount of grip changes. This effect is also caused by the new track surface cleaning, before the oils in the bitumen dissipate and the asphalt begins
to age.

One of the highlights of the clockwise Buddh circuit is Turns 10 and 11: similar in its characteristics to the famous Turn 8 in Turkey. It is fast and long, putting a lot of lateral energy through the tyres, but unlike Turkey’s Turn 8 it tightens rather than opens.

PIRELLI’S MOTORSPORT DIRECTOR SAYS:

Paul Hembery: “We’ve opted for a deliberately conservative nomination in selecting the hard tyre alongside the soft, simply because on a brand new circuit you are never quite sure of the exact race conditions you will encounter. But we’ve structured the allocation in such a way that we think the teams will run more on the softer tyres, particularly because we are bringing an extra set of soft compound tyres for Friday. This will help us to make some decisions about our strategy for next year, particularly after we saw the excellent durability of the softer compounds. It’s too early to talk about the number of pit stops we expect this weekend, but we anticipate a reasonably significant lap time difference between the two compounds.”

THE MEN BEHIND THE STEERING WHEEL SAY:

Narain Karthikeyan (Hispania Racing Team): “This is going to be one of the most challenging circuits on the calendar and, as new tracks are always a bit of an unknown I can understand the choice of compounds Pirelli has made. The texture of the tarmac is exceptionally smooth compared to most circuits on the calendar, so I think that’s a plus. The lap time difference between the hard and soft tyres is going to be huge, maybe in excess of two seconds a lap. I’d expect the teams to use the hard as less as possible: maybe just a short final stint in the race as the benefits in lap time produced by the soft tyre should outweigh its shorter life as the track surface isn’t abrasive at all and track temperatures I think should be under 40 degrees during the weekend. The long pit lane will play a part in strategy as well with teams trying to get through the race with as few stops as possible. The layout itself is going to put tremendous energy through the tyres – especially the banked Turn 10, which is a long, multiple-apex right-hander, somewhat similar to Turn 8 in Turkey. The front-left will definitely experience a lot of load through there – and there are a couple of slow speed corners that will challenge the rears on exit. So overall it will be a great challenge for the tyres and it’ll be interesting to see how it pans out. I am so looking forward to it”.

TECHNICAL NOTES:

* The simulation data for the Buddh International Circuit, which has 16 corners, suggests a lap time in the region of 1m27s. Average speed will be approximately 210kph, and the cars will reach nearly 320kph on the main straight, which will be the longest on the current Formula One calendar at just over one kilometre.

* The circuit contains a number of elevation changes, increasing the vertical energy that is put through the tyres. The entry to the corners tends to be wide in order to promote overtaking, with Turns 10 and 11 being one of the key places for passing, overlooked by a 13,000-capacity series of grandstands.

* The pit lane is one of the longest in Formula One, at over 600 metres, which will increase the time spent in the pits and therefore influence the race strategy. The race is scheduled for 60 laps, with a compromise medium downforce set-up needed. The weather should be warm and dry, in the region of 30 degrees centigrade.

PIRELLI IN INDIA:

* Pirelli’s Indian headquarters is located in New Delhi, the host city of the Indian Grand Prix, half an hour from the Buddh circuit.

* Indian supermodel Lakshmi Menon, born in Bangalore, starred in the 2011 Pirelli calendar – which was shot in Paris and launched in Moscow.

* Sales of Ultra High Performance tyres – the sector in which Pirelli is renowned as world leader – are on the increase in India. According to the Society of Indian Automobile Manufacturers, annual car sales are forecast to increase up to five million vehicles by 2015 and more than nine million by 2020.
