Regulations for the acceptance of cars

Participation in the Mille Miglia is limited to cars, or cars of similar make and model, that participated in at least one of the original races between 1927 and 1957.
All cars must comply with FIVA and FIA regulations, which require that only cars with regular official certification may participate. Cars must be original. Replicas, including partial ones, cannot be entered. 

According to the international regulations, cars are required to have a “FIVA Passport” (Fédération Internationale des Véhicules Anciens), issued by the home country federation (NSA). As is customary, the number of cars participating will be 375. 

As requests for pre-registration are normally much higher, a strict criterion of rotation of models will be applied, with precedence given as follows: 

• cars which took part in any of the original Mille Miglia
• cars with a significant competitive provenance.
• cars registered (even if it did not take part) in any of the original Mille Miglia. Documentary evidence is required. 

Under no circumstances can any car built after 1957 participate. However, a certain number of cars built before 1927 may participate, provided models of these took part in the Mille Miglia up to 1930.
Regularity Race

The Mille Miglia track is based on three part: Brescia/Ferrara, Ferrara/Roma, Roma/Brescia.
The course must be done with the media not superior to 50 Km/h.

Regulations: Coefficents

Coefficients are assigned by evaluating each model’s technical and historical characteristics and by evaluating the design. Evaluations are based on the following criteria:
1. Participation of the model in an original Mille Miglia (1927 – 1957)
2. Model year or year of modification of the car. A car will not necessarily be dated by the first year of Manufacturing
3. Cubic capacity 

4. Category (Sport [Sports Racing Cars or two-seat racing cars], Gran Turismo [GT], Turismo [Touring or Saloon Cars]) 

5. 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.
coefficient = 1 + c.model x (c.period + (c.class – c.category) + bonus) 

Where:
c.model 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 

Time Checks (CO) regulations

Basically, Time Checks place the competitors in a certain order.
When participants go through a Time Check, the real departure time from Rome is added to the given time (which is usually written on the schedule), and the result is the time through the Time Check. The schedule has the expected travelling time between two Time Checks (for example, from Rome to Siena) written on it.
Remember that departures are every 20" , therefore when the time at the Time Check is calculated, the real departure time must be taken into consideration. 

Controls in Transit (VTT - CTT) regulations

Controls in transit are used to ascertain that the pre-established route is being followed.
Each team will be assigned a time limit, or a period of time, in which they must show the tables to the officials. 

Time Trials (PC) regulations

Time Trials will be held en route. In order to participate in these trials, participants must respect the time indicated on their schedules.
Participants should keep in mind that some Time Trials will be taken at the end for some groups and at the beginning for others.
Contrary to the Time Checks, Time Trials are not regulated. Each participant will decide when to do them and place themselves at the departure officer’s disposal.
Time (in hundredths of a second) will be measured through “pressure switches”: rubber tubes connected to a printing cronometer, which reads the impulse taken from when the front wheels go over the tube.
Those who cross too early or too late will be penalized in the this trial as well.
