The 2026 NASCAR Mexico calendar has a new version that arrived on June 23 exclusively as an image posted on social media, with no press release or note on the championship's official website, and without any visible reference indicating it was an update to the current schedule. Chihuahua disappears as an option for the August 2 date, and San Luis Potosí remains as the host for that round. Puebla is moved to August 23, Mérida is scheduled for October 18 at the Autódromo Emerson Fittipaldi in what will be the first visit of NASCAR Mexico to that circuit, and the Autódromo Hermanos Rodríguez returns to the schedule as the host of the season finale on November 8, displacing Puebla, which had been listed as the championship closer until now.

During the press conference prior to the Querétaro race, the series' operating director, Humberto García, was asked about the status of Round 6, which since the calendar's presentation in January had appeared with two unresolved options, Chihuahua or San Luis Potosí, for a single race. His response was that the visit to the El Dorado Speedway was practically finalized and only operational details with local staff were missing to make the official announcement in the following days, implying that the balance was tipping toward Chihuahua.

This is the second consecutive year that Chihuahua has been left out of the schedule after having appeared in the initial plans, given that in 2025 it also figured as an alternative in the original calendar and was removed in a modification. On this occasion, it is again left out under a similar scheme of prior adjustments, despite having been included since the initial presentation, on a track with infrastructure for night racing and with consistent attendance records over several years.

Mexico City returns and the second half of the year is reorganised

The inclusion of the Autódromo Hermanos Rodríguez on November 8 resolves one of the most notable absences from the original schedule, since the capital had been left out of the 2026 calendar in an atypical situation for a series whose majority of teams operate from there. With the Hermanos Rodríguez as the season finale host and Puebla moved to August 23, the distribution of the second half of the year now has a more geographically balanced sequence than the previous version, and Mérida scheduled for October 18 adds a new venue to the calendar, at the Autódromo Emerson Fittipaldi, a layout that the series had not visited in official competition.

The background of this update goes beyond the exchange of options for a pending date, because this is the third consecutive season in which the NASCAR Mexico calendar functions as a document under permanent revision, with changes materialising without notice or public explanation. The initial 2026 schedule had already arrived with three unconfirmed dates and two with dual options, which from the start made it clear that several definitions would remain pending, but the way those definitions ultimately arrived—via an image posted on social media with no reference to anything new compared to the previous version—once again generates the same problem that teams, sponsors and fans have pointed out in recent seasons. For those organising travel and budgets months in advance, the absence of a formal channel to communicate changes is not a minor detail, and the case of Chihuahua, with two consecutive years appearing in preliminary documents and being withdrawn before the race takes place, makes that criticism difficult to refute.

With the June 23 version, the 2026 NASCAR Mexico calendar now has twelve rounds between March 15 and November 8. It would not be the first time that a numbered version of the programme ends up being replaced by another before the year is over.
