Colline dei Gonzaga marks the start of ACI Sport’s titled regularity series

The Trofeo Nazionale Regolarità (TNR) is considered the entry-level series of ACI Sport regularity. It is a championship designed to allow newcomer crews or those in a development phase to approach titled competitions, while maintaining a complete and technically educational structure.
The TNR also allows competitors to measure themselves against Supertop, Top and Driver A crews, without these categories being transparent in terms of championship standings. This solution enables top-priority drivers to use the event as a training opportunity ahead of later seasonal commitments, while offering all other competitors a valuable benchmark for their sporting development.
This type of competition allows participants to increase their experience and test both cars and timing equipment, as they face timed tests and average speed tests on real and articulated rally-style routes, within the ten age-based groups defined by the year of construction of the cars.
The subdivision into groups is precisely what makes the Trofeo Nazionale Regolarità an inclusive series, capable of rewarding a wide range of crews and enhancing cars from different eras, without the pressure typical of top-tier championships.
With the publication of the official entry list, Colline dei Gonzaga confirms its role as a key event for the launch of the 2026 TNR season. More than 70 crews are expected at the start, featuring a wide variety of historic cars and a broad representation of teams and experience levels.
It is an ideal context for a first seasonal comparison, useful both for those aiming for a consistent presence in the trofeo and for those using the TNR as a test bench ahead of more demanding commitments, or for crews targeting qualification for the ACI Sport Supercup Final.
With Colline dei Gonzaga, the season of ACI Sport’s titled series takes shape, opening a phase in which Italian regularity fully comes to life, through championships, trophies and events increasingly differentiated by technical level and sporting objectives. The calendar continues immediately the following weekend (6–7 February) with another major event: the Coppa Giulietta e Romeo, which will mark the start of the Italian Historic Regularity Championship (CIREAS).
