Located a mere two blocks from the Atlantic Ocean in Daytona Beach, Fla., Daytona International Speedway is a 2.5-mile trioval race track positioned on 480 acres of property that includes a 29-acre lake (Lake Lloyd) and a road course configuration. Daytona is owned by the France family, the same family that founded NASCAR. Each year, Daytona International Speedway is the site of a variety of races including the Grand American Road Racing Association's Rolex 24 at Daytona, The American Motorcycle Association Daytona 200 and five NASCAR races including the Coke Zero 400 during the Independence Day weekend. Because of this diversity, Daytona has been dubbed the "World Center of Racing." With a true year-round racing schedule, Daytona is one of the only tracks that can boast so many different forms of racing.
Daytona is a superspeedway -- any track over two miles (3.2 kilometers) in length (excluding road courses) and featuring high-banked turns -- that can seat 168,000 race fans. On the NASCAR schedule, Sprint Cup, Craftsman Truck Series and Nationwide Series cars race on two superspeedways with Talladega being the other example. At 2.5 miles (4.02 kilometers) long, Daytona is second in length only to Talladega which is 2.66 miles (4.3 kilometers) long. Let's take a quick look at Daytona's vital statistics:
- Type: Superspeedway
- Seating: 168,000
- Configuration: Trioval
- Turns: 4
- Width: 40 feet (12.2 meters) (racing surface)
- Turn length: 3,000 feet (914.4 meters)
- Front stretch length: 3,800 feet (1,158.2 meters)
- Chute length: 1,900 feet (579.1 meters) (from the middle of the trioval to turns 1 and 4)
- Backstretch length: 3,000 feet (914.4 meters)
- Total length: 8,700 feet (2,651.8 meters) or 2.5 miles (4.02 kilometers)
- Banking: 18 degrees at the start/finish line, 31 degrees in turns

Thirty-one degrees of banking is pretty steep. To get an idea of the angle, the top of the track near the outside wall is more than 35 feet (10.7 meters) above the infield -- that's higher than the roof of a typical two-story house. As a result of the extreme banking in the corners and the length of the track, stock cars can travel at speeds in excess of 200 mph (322 km/h). While those speeds are relatively safe for a car with an extreme amount of downforce such as a Grand-Am sports car or an Indy car, stock cars have a tendency to lift off the ground when they reverse direction at high speeds, as in the case of a spin. Because of the instability at such high speeds, NASCAR gives each team a carburetor restrictor plate to cut-down the horsepower from more than 700 to around 450. This reduces the top speed of the cars considerably. Obviously, this is why you may hear Daytona referred to as a restrictor-plate track.
NASCAR drivers seem to universally agree that stock car racing and Daytona International Speedway go hand in hand. The original Daytona track can be traced back to the 1950s where the cars used the hard-packed sand of the Daytona shoreline as the original racing surface. Those days are long gone, yet the spirit of NASCAR remains in Daytona. Two times a year, NASCAR's top racing series visits the hallowed race track. The first visit is for the race that defines NASCAR -- the Daytona 500.
