![]() ![]() For super sedan there is SS/A for v8 cars, SS/B for six cylinder cars, and SS/C for four cylinder cars. Specially built cars also have an identification system but this is much simpler. A category can have cars that are classified (have a class) or that are specially build for the category. Some categories are predetermined by the national governing body for example “Super Sedan”. Each class has its own national record for ET and for speed (mph)Ī category or bracket is a group of vehicles that race together to produce one winner. There are a few exceptions, and there are differences in the way different governing bodies make up the classes. A is an altered, D is a dragster, FC is a funny car, TS is a top street (street appearing), DB is a dragbike, PCB is a pushrod bike (like an old style Triumph or Harley). The second part (the ‘D’ in this example) is the body style. If the letter is a double (eg AA) this means the engine has a “power adder” such as a supercharger, turbocharger(s) or NOS. A powerful engine in a heavy car/bike will have a lower letter than the same engine in a lighter car. The first (the ‘A’ in this example) is its power to weight ratio with the lower the letter, the heavier or less powerful it is – ‘A’ being the lightest most powerful combination, and H being the heaviest least powerful combination. A class designation (such as A/D) is made up of two parts. A class is a specific specification for a car/bike, including its body style, engine type/size and its weight. ![]()
