New Delhi: Formula one circuit might not be a mechanical part of an F1 race but it requires highly proficient skill and capability to develop and build international tracks on which some of the highly researched machines roar.

Like football or cricket stadiums, Circuits too are the theatres of sports. Some require a great deal of technical ability while others are built for pure speed.

An F1 circuit is made up of three layers; the top layer is called as Wearing Layer. The Middle layer is called as Binding layer. It smoothens out bumps and provides top layer with the required stability and balance. The third layer or the base layer is termed as the Bearing Layer. It is made up of coarse asphalt and is the fundamental part of the formula one track.

Let’s know about the India’s battlefield where the racers will talk with the speedometers and also have a look on statistics of the other top Formula One circuits around the world.

Name: Buddh International Circuit, Greater Noida, India

Race distance: 308.4 km / Circuit Length: 5.137 km
Number of Laps: 60 / Number of turns: 16
Capacity: 150,000 approx.
Established: 2011
First Race: 2011

The track got its name from spiritual leader Gautam Buddha and is located at a distance of 50 kms from national capital of India, New Delhi. 

Spread over 875 acres, the fastest lap time on the track is expected to be under one minute and 27 seconds with average speeds crossing 210 kmph.

On the straightest part of the track F1 car can reach a top speed of 320 kmph. On this part of the track devices like DRS and KERS will be really effective.

The track, designed by renowned circuit architect Hermann Tilke, stretches to 5.137-kilometres and is expected to seat up to 150,000 spectators.

Four million cubic tons of earth was moved to give the track plenty of undulation, and it rises 14 metres between Turns One and Three alone.

Silverstone:

Name: Silverstone Circuit at Silverstone in Great Britain
Race distance: 306.227 km / Circuit Length: 5.141 km
Number of Laps: 52 / Number of turns: 18
Capacity: 150,000 approx.
Established: 1947
First Race: May 13, 1950

Silverstone was built on the site of an old RAF airfield with the original circuit making use of the three runways in a triangle formation.

The first race at the circuit is reported to have taken place in September 1947.

The race was plagued by sheep wandering onto the circuit; the event was nicknamed the 'Mutton Grand Prix' after Geoghegan hit one of the unfortunate creatures, signalling the end for both car and sheep.

In 1949 the layout was revised to use the perimeter track and this layout formed the circuit for the first Grand Prix held there in May 1950. The race was won by Nino Farino in his Alfa Romeo, finishing two laps ahead of team-mate Luigi Faglioli.

After the 1990 Grand Prix, Silverstone underwent a major redesign in time for the 1991 race which proved popular with fans.

Having hosted the British Grand Prix permanently since 1987, rifts began to show between the British Racing Drivers Club (BRDC), who owned the facility, and the FIA.

In December 2009 British Racing Driver's Club (BRDC) president Damon Hill announced that they had agreed a 17-year deal to keep the race at Silverstone, and a 5 million euro refurbishment, which involved changes to the track layout, followed.

Circuit de Monaco

Name: Circuit de Monaco
Race distance: 260.520 km/ Circuit Length: 3.340 km
Number of Laps: 78 / Number of turns: 19
Capacity: 120,000 approx.
Established: 1929
First Race: 1929

The Monaco Grand Prix is the one race of the year that every driver dreams of winning.

To win in Monaco places a driver's name on a list that includes many of history's all-time greats. Both Graham Hill, the man nicknamed 'Mr Monaco', and Schumacher have won it five times, Alain Prost took four victories, whilst Stirling Moss and Jackie Stewart each won here three times.

But the record of wins in the Principality resides with the Senna, who won in Monte Carlo six times.
The race has been a regular fixture of the world championship since 1955, but in that time the circuit has changed remarkably little.

Slight alterations were made for the 2003 event, in particular a new, gentler entry to the Rascasse corner, with even bigger changes in 2004, with a new pit complex and increased spectator capacity.

Nürburgring Circuit

Name: Nürburgring Circuit, Germany
Race distance: 308.863 km/ Circuit Length: 5.148 km
Number of Laps: 60 / Number of turns: 16
Capacity: 290,000 approx.
Established: 1927 (rebuilt 1984)
First Race: 1951

The original Nurburgring, the Nordschleife, ran for an awe-inspiring 22.5 kilometres (14 miles).
The Nurburgring was, in fact, two circuits: the Nordschleife and the Sudschleife. In total they had an amazing 172 corners.

Following Niki Lauda's terrifying accident there in 1976 in which he suffered horrendous burns, the Nurburgring's license to hold Formula One events was withdrawn.

The track underwent huge redevelopment to create a new circuit and in the spring of 1984 a race was held featuring 20 identical Mercedes 190Es and a grid composed of some of the best-ever Formula One drivers.

Niki Lauda, Carlos Reutemann, Keke Rosberg, Alain Prost, Ayrton Senna, James Hunt, Stirling Moss, Jack Brabham, Phil Hill, John Surtees and Denny Hulme were just a few of the names to take part. Senna, then a relative youngster, won from Lauda and Reutemann.

The European Grand Prix was held at the new track later that year, and again in 1985, but it disappeared again after commercial difficulties. With the ascendancy of Michael Schumacher, from nearby Kerpen, the track was once again back in Formula One in 1995. Posing as the Luxembourg Grand Prix for 1997 and 1998, it then once more became the home of the European Grand Prix until 2006. From 2007 it has played host to the German Grand Prix every other year in an agreement which sees the race alternate between there and Hockenheim.

The track may not be as challenging as the old circuit, but it is still possible to take a trip down memory lane - literally. For just a few euros one can take a car onto the old track and soak up what was one of the most feared and yet respected circuits in the history of motorsport.

Circuit de Spa-Francorchamps

Name: Circuit de Spa-Francorchamps, Belgium
Race distance: 308.052 km/ Circuit Length: 7.004 km
Number of Laps: 44 / Number of turns: 19
Capacity: 90,000 approx.
Established: 1920
First Race: 1950

Belgium's Spa Francorchamps circuit is one of the oldest on the current F1 calendar, hosting its first race in 1922 and its first grand prix in 1925.

The original circuit made up of narrow roads was 9.3 miles long (14.9km) and was notoriously dangerous. It was a fast course and until 2000 it was possible to travel over the track as it was a public road.

At the 1960 grand prix Chris Bristow and Alan Stacey were killed within minutes of each other, and in 1966 Jackie Stewart crashed and found himself upside down in the cellar of a farmhouse with petrol pouring over him.

The old track hosted its final race in 1970, when it was deemed too dangerous for F1; a year earlier drivers had boycotted the race Spa was missing from the F1 calendar until 1983 when it returned with a drastically reduced circuit of almost 4.5miles. Despite the cuts in length the circuit still managed to retain its magic. The mix of long straights and fast corners, combined with a picturesque setting and notoriously changeable weather keeps it at the top of both drivers and spectators favourite circuits.

Part of the magic of Spa is that it is known and respected as one of the most challenging in the world, and to prove that fact only six drivers have managed to win the Belgian Grand Prix at Spa more than twice: Juan Manual Fangio and Damon Hill both have three wins to their name, Jim Clark and Kimi Raikkonen managed one better with four wins and Ayrton Senna won the race five times. The undisputed Spa master though, is Michael Schumacher who has won a record six times.

Autodromo di Monza

Name: Autodromo di Monza, Italy
Race distance: 306.720 km/ Circuit Length: 5.793 km
Number of Laps: 53 / Number of turns: 11
Capacity: 115,000 approx.
Established: 1922
First Race: 1950

Monza was built in 1922 and for many years one of the fastest circuits. It was the first purpose-built venue to stage a grand prix and the first to charge for entry. It was also two tracks. One, a US-style oval with two straights and two heavily-banked corners (demolished in 1938) the other a facsimile of a road circuit.

It is the fastest track on the Formula One calendar. The average speed of the circuit is 250 km/hr and the top speed of 320 m/hr. The top speed measured at Monza (Italy) track is 360 km/h (225 mph).
In 1928 a driver and 27 spectators were killed, and despite safety modifications, five years later three top drivers died in one race.

One of the old-school of grand prix circuits Monza has a very special atmosphere; the Italians often refer to it as "La Pista Magica" or the magic track.
