2020 NASCAR PEAK Mexico Series

The 2020 NASCAR PEAK Mexico Series was the thirteenth season of the NASCAR Mexico Series, a regional stock car racing series sanctioned by NASCAR in Mexico. It is the sixteenth season of the series as a NASCAR-sanctioned series. It began with a race at the Autódromo de Querétaro on 9 July, and concluded with a race at the Autódromo Miguel E. Abed on 18 December.

Rubén García Jr. entered the season as defending champion, having won his 3rd title in 2019.

The 2020 season was affected by the COVID-19 pandemic, which resulted in the postponement and cancellation of several races. As a replacement, the NASCAR Mexico Series hosted virtual races on the sim racing game iRacing, on popular NASCAR tracks such as Daytona, Charlotte, Homestead and Watkins Glen.

The season eventually began in July, and featured 12 races across 9 weekends, with two doubleheader weekends hosted at the Autódromo de Querétaro, and one at the Autódromo Miguel E. Abed. The series worked closely with local health authorities to announce rescheduled races and protocols that would be followed to mitigate the spread of COVID-19. This included several races which would be held behind closed-doors, with no spectators permitted, along with some race weekends being condensed down to one-day events.

Rubén Rovelo became champion at the end of the season (1st title), beating out defending champion Rubén García Jr. by 14 points. Rovelo had a 22-point advantage heading into the final race at Autódromo Miguel E. Abed, an advantage that allowed him to mathematically clinch the championship by starting the race.
