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. It is also notorious for the diversity of its drivers. As the series allows drivers to debut at age 15, several young Mexican talents are choosing the T4 Series to start their NASCAR careers. On the other hand, there are several 40-something drivers who have been racing in the series since it began in 1994.
The series ran a 10-race schedule from April to November. 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.
Origins (1994–2004)
The series is the oldest of the current touring car racing series in Mexico. It started in 1994, being called Reto Neon (Neon Challenge). It used to be a low-cost racing series that featured modified Dodge Neon cars competing in one-hour timed events. Two drivers (usually an expert and a rookie) would share every car, each one driving one half of the race.
The idea worked well for several years. 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. It also proved to be a good learning ground for young drivers new to racing.
Start of the series
Desafío Corona (2004–2006)
The Reto Neon ceased to exist in 2004, when the Desafío Corona series was founded. OCESA, the promoter of the new series included the Dodge Neon cars as one of their three categories, with the stock car series (now NASCAR Mexico Corona Series) being the premier series. The former Reto Neon became the T4 Series starting in 2005. In the inaugural season it was known as Lotto T4 Series, after the Italian sportswear firm decided to sponsor the series for that year.
In 2006, when it was made evident that NASCAR was considering to include the Desafío Corona as one of their international divisions, the T4 Series underwent several changes as it was adapted to the NASCAR format. 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 addition to this, standard NASCAR rules, such as the beneficiary rule (commonly known as "Lucky Dog" or "Free Pass"), green-white-checker finishes, and double-file restarts established. Also, it became a multi-manufacturer series, with the inclusion of the Chevrolet Astra in addition to the Neon.
NASCAR Mexico (2007–2008)
The creation of the NASCAR Mexico Corona Series was announced at the 2006 awards ceremony. The T4 Series was confirmed as the supporting series and was renamed to NASCAR T4 Series, the series ran during 10 of the 14 NMCS weekends.
A period of transition started in 2007, with the release of a new car spec. The new "Mini Stock car", as it is called, is a Rear-wheel drive car (as opposed to the FWD Dodge Neon), and it features most of the elements of the larger stock cars (such as transmission, suspension, brakes, etc.), while keeping the 4-cylinder engine.
In theory, the Mini Stock car is designed to offer a performance very similar to the old T4 chassis. While teams are being encouraged to switch to the new car, those not wanting to do so are being grandfathered in the series.
Mini Stocks (2009–2010)
The series changed name to NASCAR Mini Stock Series and the period of transition came to an end and all of their cars have changed to the RWD regulation. In 2010 was the first year of the Nissan in the series.
Stock V6 Series (2011–)
The series was folded after 2010 season, and was replaced by NASCAR Stock V6 Series, the cars also increased to six-cylinder engines.
