Talladega Superspeedway (2.66 miles, Super Speedway, tri-oval) in Talladega, Alabama

At the Talladega Superspeedway, two of the four "restrictor-plate" races are held, in which the engine power is throttled with air restrictors to the speeds under 200 mph to keep (320 km / h). The high speeds are only due to the thickness of such tracks like Daytona and Talladega just possible, with the track in Alabama is even the larger of the two: 2.66 miles (4.28 km) is a spin on the Super Speedway long and the curves are inflated with 33 °. Come to this insane Banking else zoom only Daytona (31 °) and the Bristol Motor Speedway (28-30 °). Rusty Wallace has confirmed in 2004 impressively, the implications of these dimensions: In a test with no air restrictors he reached a top speed of 228 mph (367 km / h) on the back straight, what a round average of 221 mph (355 km / h) with the result. But this is not the official course record, because it was not set up during a race weekend.

The record for eternity holds namely Bill Elliott with his pole lap from the year 1987, when he with a speed of 212.809 mph (342.482 km / h) moved his Ford Thunderbird around the oval - on average, mind you! During the actual race a day later then lost Bobby Allison after a puncture his Buick and took off in a row a spin. Allison's car hit his tail into the catch fence. Similar to Carl Edwards' accident in the spring of 2009, with also some spectators were injured by flying debris. The difference between the two accidents: Edwards Ford "surfed" with the roof ahead of the catch fence, which threw him back eventually quickly get back on track, while Allison an entire portion of the fence completely aroused the. "Roof flaps", ie the moving flaps on the roof of the car, their assertion is to prevent lifting, only in 1994 were introduced. While they could have prevented Allison's impact, they were in Edwards' accident powerless. The # 99 was already on the way to the ground after the "flaps" another upgrade after Dreher prevented, but was unhappy hit by Ryan Newman, who carried the Ford back into the air.

The events in 1987 had then the introduction of the "restrictor plates" made in, while the recent crash of an increase in the catch fences from 14 to 22 feet (4.26 m to 6.71 m). Also applicable to the super speedways the "impound" procedure, which has been introduced for reasons of cost. After two free practice sessions on Friday followed by qualifying on Saturday. After that no more major changes may be made to the car. Because of the "restrictor plates" would go with a wholly-owned qualifying setup and expensive special parts a lot more on speed. This procedure is intended to prevent the financially strong major teams here have an advantage because they could rebuild their cars will. NASCAR wants all cars on the track are traveling possible only in race trim, so that costs and time can be saved.
