The Mazda RX7 was one of the few classic sports cars to come from Japan. Known for its sleek styling, unique rotary engine and affordable price, the two-door coupe was an instant hit from the moment it was introduced for the 1979 model year.

Drag Racing

The Mazda RX7 is a popular choice for drag racing.  In drag racing, the objective is to complete a given straight-line distance, from a standing start, ahead of a vehicle in a parallel lane. This distance is traditionally &fraq14; mile (400 m), though 1/8 mile (200 m) has become popular since the 1990s for this type of racing. The vehicles may or may not be given the signal to start at the same time, depending on the class of racing. Vehicles range from the everyday car to the purpose-built dragster to sports cars such as the Mazda RX7. Speeds and elapsed time differ from class to class. Average street cars cover the &fraq14; mile in from 10 to 15 seconds whereas a top fuel dragster takes 4.5 seconds or less, reaching speeds of up to 530 km/h (330 mph). Drag racing was organized as a sport by Wally Parks in the early 1950s through the NHRA (National Hot Rod Association). The NHRA was formed to discourage street racing.

Launching, a top fuel dragster will accelerate at 4.5 g (44 m/s²), and when braking parachutes are deployed the deceleration is 4 g (39 m/s²), more than the Space Shuttle experiences. A top fuel car can be heard over 8 miles (13 km) away and generates a reading of 1.5 to 2 on the Richter scale.

Drag racing is two cars head-to-head, the winner proceeding to the next round. Professional classes are all first to the finish line wins. Sportsman racing is handicapped (slower car getting a head start) using an index (a lowest e.t. allowed), and cars running under (quicker than) their index "break out" and lose. The slowest cars, bracket racers, are also handicapped, but rather than an index, they use a "dial-in". Bracket racing has been viewed as the main cause of the loss of public interest in drag racing. People don't understand why the slower racing car wins or why somebody needs to hit the brakes to avoid going too fast. Many local tracks have also complained that bracket racers will also go out of their way to spend as little as possible while at the track by bringing their own food, beverages, fuel and supplies thus, making it more difficult for tracks to make money on these events. This causes gate prices to rise and tracks losing interest in having such events.
