Vehicle width x Wheelbase / 2 This number is used to divide penalty points for reversing, hitting obstacles, and knocking down marker sticks in the Original, Standard, Modified, and UTV classes. The vehicle’s measurements are taken from the factory specifications of the base model. This so-called German system includes an exception: the Suzuki Samurai, SJ413, and SJ410 are all considered to be the same size.
