Desafío Corona

NASCAR founded the series in 2004 in conjunction with OCESA, a Mexican entertainment company.

After the end of the 2003 season, it was presented at the season finale, the Teleton 100, the new 2004 stock car, a Pontiac Grand Prix, which marked the end of the trucks chapter, and the start of a new era: stock car racing in Mexico.

This race was won by Jorge Goeters (Canel's #18 Pontiac), after 90 laps to the 1-mile (1.6 km) oval.

Núñez spent a week in intensive therapy, only to die of complications by the crash, including a broken pelvic bone and a perforated lung.

The series' competitors race stock cars similar to those used in late model classes at short tracks in the United States, with fiberglass composite bodies and spec engines.
