Coefficients are assigned by evaluating each model’s technical and historical characteristics and by evaluating the design. Evaluations are based on the following criteria:
Participation of the model in an original Mille Miglia (1927 – 1957)
Model year or year of modification of the car. A car will not necessarily be dated by the first year of Manufacturing
Cubic capacity
Category (Sport [Sports Racing Cars or two-seat racing cars], Gran Turismo [GT], Turismo [Touring or Saloon Cars])
Bonus if the specific chassis number was entered or has taken part in an original Mille Miglia (documents required)
In order to ensure an objective coefficient, a mathematical formula is used..
To obtain the final coefficient of each vehicle, partial coefficients for c .model, c. period, c. class, c. category and any bonuses for the chassis must be entered.
Model coefficient.
= 1 if the model (meaning chassis type and not the body) participated in the original Mille Miglia;
= 0.50 if the model was never entered in the Mille Miglia, but took part in the commemorative rallies of it, since it in an important model for that historical period.
c.period
Period coefficient.
It decreases from 1927 to 1957. The 24 original editions have been divided into seven historical periods, each one characterized by an extensive change in the International Sporting code and/or Race Regulations and/or by the introduction of significant new car technologies.
c.class
Class coefficient.
It decreases with the capacity, without taking the supercharger into account.
c.category
Category coefficient.
= 0 for Sports Racing Cars (complying with the period Appendix C to the International Sporting Code of AIACR or FIA);
= 0.10 for GT cars;
= 0.20 for Touring cars.
bonus
= 0.10 if the vehicle (the chassis number now entered) participated in the original Mille Miglia;
= 0.05 if the vehicle (the chassis number now entered ) was entered, but did not participate in, the original Mille Miglia

The coefficient given to the vehicle will be available on-line along with the acceptance of the car. It will also be confirmed in the letter of acceptance.
