The T4 Series featured the largest grid in Mexican motor sports, with more than 30 teams running full-time and a few others doing a limited schedule.
Races are shown live on AYM Sports, a Mexican sport-related satellite TV station available in Mexico, Central America, and the south of the United States.
It used to be a low-cost racing series that featured modified Dodge Neon cars competing in one-hour timed events.
Having a relatively inexpensive racecar and two drivers sharing the cost every race allowed to have a massive participation, with grids often exceeding 50 cars.
The most notable changes were the introduction of pit stops, the allowance of only one driver per car, and a schedule that consisted entirely of oval tracks.
In theory, the Mini Stock car is designed to offer a performance very similar to the old T4 chassis.
Additionally, a brief summary of every race is usually shown during the broadcast of the NASCAR Mexico Corona Series events on Televisa Deportes and the Latin American version of Speed Channel.
Local radio and TV stations also hold interviews with some of the most popular drivers to increase awareness of the series among the fans.
