Regulations and Classes
From the 2020 season, the regulations were completely revised. This is in recognition of the ever-growing range of Morgan cars produced and still being made today.
The scoring system is now based upon target times specific to each car and driver combination. This uses vehicle parameters (power, mass, drag coefficient and tyre friction coefficient) and circuit information deduced from satellite image analysis to simulate a run of any particular course for each entrant vehicle.
The power is calculated from the harmonic mean BHP of the engine at the flywheel. The Championship has nominated specific MAHA MSR500 rolling roads. See REGULATIONS section 1.6.1 a. Graphs and figures from other rolling roads will not be accepted.
The mass, defined as the Kerbside weight, will be validated for all entered cars once per season. Kerbside weight is defined as the weight of the car, including driver (in race overalls, helmet, shoes and gloves), in the condition in which it is presented to the start-line ready for competitive timed runs. It is assumed the car will be carrying 10 litres of fuel.
Each competitor must nominate a tyre category – List 1a, List 1b or List 1c on their entry form when registering for the championship. The tyre category determines the type of tyre the competitor is permitted to run during the year.
There are 12 classes plus a number of subclasses that cars can be entered into. These are determined by the original model and the level of modifications made.
