71:(F600), and is a closely regulated class. Several chassis manufacturers produce different designs to a tight dimensional ruleset. Engines are specified by the ruleset, and builders are not allowed to modify engine internals. Instead of traditional dampers and springs, F500 cars utilize a very simple elastomeric spring medium contained in a cylindrical canister. The rules state the elastomer must be 2" in diameter by 1" in thickness, but the design and implementation of the elastomeric springs (commonly called "pucks" by the competitors) is wide open. Additionally, each chassis manufacturer produces bodywork of their own design, which adheres to dimensional constraints. These regulations allow for very competitive racing at a relatively low cost, which rewards driver and car set-up skills. In 2023, the class was renamed to Formula 600.

These simple belt driven automatic transmissions are tuned to optimize the power curve of a two-stroke engine, constantly keeping the engine at its peak power. One of the key benefits of the CVT is that it is a stepless transmission. This allows all of the engine's power to be transmitted to the
