Bristol Motor Speedway
Bristol Motor Speedway (0.533 miles, short track, 2x 180-degree turns) in Bristol, Tennessee
The Bristol Motor Speedway is one of the oldest and most traditional routes in the current NASCAR calendar, because in "Thunder Valley" two races per season been played since 1961. The short track speed skating is a few miles outside of Bristol, whose main street is, curiously, also marks the border between Tennessee and Virginia. The oval is located in the Tennessee section and was initially built in 1960-1961 with a superelevation of 22 ° and an asphalt surface. 1969, was the first conversion, which gave the course a banking of 36 °, but this was often provided by teams and drivers in question. So once could only measure 26 °, the crew of Ryan Newman during a test.
In 2007, which also saw the premiere of the "Car of Tomorrow", the Speedway was a complete renewal of the road surface including a variable banking between 24 ° and 30 ° donated. Five years later there was a further change to the superelevation, because the fans complained about the loss of the popular Bump-&-run maneuvers, because yes, there were suddenly two equal lanes. The uppermost Lane was so unceremoniously planed for late summer 2012 race. 0.533 miles is a long round in Bristol, which is about 858 meters, where the short track speed skating has the characteristic track surface made of concrete by the way since 1992. So Bristol is indeed longer than 11m Martinsville and thus not the shortest half-mile in the calendar, but the fastest, bringing the speedway is also campaigning for years. The banking allows cornering speeds between 110 and 120mph, which at "full throttle" the launch of a catapult similar in corner exit.
Two other things are also quite typical of the Bristol Motor Speedway. Firstly, there were no race there since 1961 so far, which was not completely sold out, took place in consequence of the economic crisis in 2008, this series but unfortunately an end. The seating capacity was expanded from 18,000 to 160,000 seats over the years, which one behind Indy, Texas, Daytona and the Lowe's Motor Speedway occupies the fifth place in the Sprint Cup. Secondly, the track is placed on murder moderately small space, which not all three national racing series find space in the infield during the race in late summer. The trucks are then already in the night from Wednesday to Thursday.
The space is limited so that the transporter of the Cup and the Nationwide Series by the tunnel entrance drive into the infield and be lined up there to an ingenious system. In addition, the pit lane is divided into two, so what also no longer exists in the Sprint Cup, which results in a special regulation for pit stops. By the year 2002, less qualified teams only got a place in the pit lane of the back straight. Later there was a rule change so that we have the following procedure today: Under yellow, both parts form a single unit and the entrance to the pit lane is located in the output of Turn 2, while the exit Turn 1 is the introduction. Thus, the course must be once orbiting in the boxes, so nobody has an advantage or disadvantage. Substrates is the two-part scheme to fruition. One drives virtually the portion of the pit lane directly to where the Pitstall own lies. The input is therefore in Turn 2 or Turn 4, the output in Turn 1 or Turn 3
