Currently, Turismo Nacional is made up of two divisions, which share the calendar but the races run separately.

Class 3 cars are limited to 2.0 liters of displacement; mainly, C-segment models are allowed.

From its inception, the category organized its competitions, dividing its fleet into classes, for which the size of the vehicle and the displacement of the engines had to be taken into account.

The smaller division is known as Class 2, which is intended for those cars of national production, standard preparation and with a maximum displacement of 1600 cm3.

With the elimination of import restrictions due to the creation of Mercosur, models produced in Brazil were admitted to the category.
