Texas Motor Speedway
Located in Fort Worth, Texas, the Texas Motor Speedway was built between 1995 and 1996. The original track featured a dual banking system with a 24-degree bank for stock cars and an 8-degree bank for open-wheel vehicles. The track is classified as a superspeedway as it is more than one mile in length and it is similar in layout to the Atlanta Motor Speedway and Lowe’s Motor Speedway. The track’s ‘Turn 4′ was reshaped in 1998 to make transitions from the turns to the straightway easier. Further renovations that same year eliminated the dual banking and resulted in the track currently in use today.
The Texas Motor Speedway measures 1.5 miles in length and features a quad-oval design. It has been banked 24 degrees in the turns to facilitate fast racing and the front straightway juts outwards a bit. It also has a seating capacity of more than 200,000 for NASCAR and IndyCar racing events. The track features tunnel bumps on Turns 2 and 4 which add to the its uniqueness. The track is currently owned by Speedway Motorsports Inc. At one stage the Texas Motor Speedway was considered to be the ‘fastest non-restrictor plate track’ to appear on the NASCAR circuit. Qualifying speeds exceeded 192 mph and corner entry speeds were often clocked at over 200 mph. However, with the gradual wear of racing surfaces other tracks, such as Atlanta, proven to be faster. Currently the top qualifying record is held by Brian Vickers who posted a 196.235 mph speed in 2006.
The Texas Motor Speedway is home to two NASCAR NEXTEL Cup races – making it a very popular racetrack with big attendance figures. The races which it hosts are the Samsung/Radio Shack 500 and the Dickes 500. It also hosts the O’Reilly 300 and the O’Reilly Challenge – both of which are Busch Series Races. The Bombardier Learjet 550 is the only Indy Racing League race that it hosts.
