Buddh International Circuit – Indian GrandPrix

Buddh International Circuit located about 50-kilometres south east of capital city New Delhi in India. The complex is a part of Jaypee Greens Sports City which covers about 2,500 acres and the circuit area zones about 875 acres. The circuit capacity can be extended to 200,000 but now it can seat 150,000 spectators.

The name is derived from the word Buddha, represents peace and calm.The circuit is designed by F1’s veteran designer Hermann Tilke and had undergone few changes considering the inputs from teams. Few amendments were made to enhance overtaking in the circuit and to showcase the event a true spectacle.

This track is simply a mix of some notorious corners from various circuits. It offers everything a good circuit wants and it is a mighty challenge to tackle with for both drivers and engineers.It’s already been considered as challenging as Spa.

DRS Zone:

The first zone’s detection point is 10 metres after the penultimate Turn 15, with its activation point just 36 metres into the start-finish straight, which should ensure plenty of passing into the third-gear right hander that is Turn One.

After flowing through the gentle, left-hand curve known as Turn Two, the second zone’s detection point comes 16 metres before the Turn Three hairpin. Drivers can then activate DRS 510 metres into the New Delhi circuit’s back straight, which is one of the longest on the calendar.

That heads into a low-speed, second-gear right hander (Turn Four), which again should present a good overtaking opportunity.

Four million cubic feet of soil is used to create undulations, as a result the 14 metres elevation put drivers on a roller coster ride from turn 1 to turn 3. During practice and qualifying the adjustable DRS wing can be used for approximately 62% of the lap, similar to Spa. In the race it will help overtaking on the straight. With 20 metre track width, overtaking should not be a problem and the track appeared to ve no real bumps and tarmac surface is smooth.

Amount of fuel a car carries is a bit high so it could test the fuel on board and relative fuel consumption for any team.The tyre compound chosen is interesting because we haven’t seen Hard/soft combination since Silverstone. Pirelli reported that the unknown nature of the track let them to be more “conservative”.
Simulations suggests that the track will have 80% of the tyre energy of Suzuka. With corner radii, length of straights unknown teams would utilise friday practise sessions to gather as much as possible from gear ratios to tyre degradation.
Notable turns :
Turn 3 is an up-hill right hand corner dealt with braking from 200 mph to under 60 mph where drivers experience over 5g of lateral forces. Turn 10 and turn 11 are similar to turn 8 in Turkey, rather it’s a multi apex right hander and it hurts the front left tyres and wheel spins on slow corners can hurt the rear tyres. Hard tyres are particularly where Ferrari is not good at.
Race Strategies :
Pit lane runs for 600 meters, 20 seconds expected for pitstop it is not worse than what is anticipated. Drivers will make 3 pitstops, means one small stint in hard and two stops in soft tyres. But for teams like Sauber, Force India and STR it is the other way around.
