The round figures will be obtained by raising by one the figure to be adopted when the next figure is equal to or greater than 5. The checking of the cylinder capacities, both in France and abroad, will be carried out before the race. Competitors should apply to the Automobile Club de l'Ouest so that a race Steward may call at their works or garages - or someone appointed by the race Stewards entrusted with the checking and marking of engines. Competitors must have the cylinder capacities of their engines checked at their works. The dismantling of the engine is compulsory.

In the case of foreign cars, the race Stewards may also appoint a deputy to carry out the checking in the factories or garages or empower the sporting body of the country recognised by the I.A.R.A.C.
