Bristol Motor Speedway
Bristol Motor Speedway (0.533 miles, short track, 2x 180 °-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 are already held 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 portion and was first built in 1960-1961 with a superelevation of 22 ° and an asphalt surface. In 1969 took place the first tag that 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 got a complete renewal of the road surface including a variable banking between 24 ° and 30 ° donated. Five years later there was a further change in the curve superelevation, because the fans over the loss of the popular Bump - Run maneuver complained because so suddenly there were 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 way, since 1992. So Bristol is indeed longer than 11m Martinsville and therefore not the shortest half-mile in the calendar, but the fastest, which also advertises the Speedway 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 for the Bristol Motor Speedway. Firstly, there was no race there since 1961 until now, which was not completely sold out, was due to the economic crisis of 2008, this series but unfortunately an end. The spectator 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 is the fifth in Sprint Cup. Secondly, the track is placed on murderously tight space, which not all three national racing series can be accommodated in the infield at the race in late summer. The trucks are then already in the night from Wednesday to Thursday.
Space is limited so that the transporters of the Cup and Nationwide Series through the tunnel entrance drive into the infield and be lined up there for a sophisticated system. In addition, the pit lane is divided into two parts, 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 were given only one place in the pit lane of the back straight. Later there was a rule change, so 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 path must be surrounded once in the boxes, so that nobody has an advantage or disadvantage. Under Green is the two-part scheme to fruition. It runs virtually the part 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 third
