many manufacturers involved, such as Campeonato Brasileiro de Marcas e Pilotos that included the involvement of Chevrolet, Fiat, Ford and Volkswagen, as well as the always popular Formula racing championships. In 1994 the championship returned to the old rules and Chevrolet announced that the Chevrolet Omega would be introduced as the new standard model. As part of a marketing strategy and in order to reduce costs, the tickets were free and the races were now held in double rounds sponsored by Brazilian Formula Chevrolet in an event called Chevrolet Challenger. This decade marked a dominant era for Ingo Hoffmann with eight titles, three in partnership with Ângelo Giombell. His only serious challenges came from Paulo Gomes in 1995 and Chico Serra in 1999. 2000s From 2000 on, General Motors departed the series' management and Vicar Promoções Desportivas, owned by former racing driver Carlos Col, took over the organization. This ushered in a period of modernization and improved security as the category started to use a tubular chassis designated JL G-09. The project engineer was Edgardo Fernandez, who did something similar for the Argentina category Top Race V6, inspired by both NASCAR and the DTM. The chassis was built by Zeca Giaffone's JL Racing. In 2003 the category replaced the Chevrolet 6-cylinder engine used with modifications since 1979 with a Chevrolet V8 imported from the United States by JL Racing, similar to the engines used by the NASCAR Busch Series. Despite not managing the series anymore, General Motors still participated in the series with the Vectra. In 2005 Mitsubishi entered the series with the Mitsubishi Lancer, marking the first time in the series' history in which Chevrolet was not the sole manufacturer competing. 30 October of that same year marked the first race held in Argentina at Autódromo Juan y Oscar Gálvez, alongside the TC 2000 category. Attendance was 70,000. Giuliano Losacco was the winner, with Mateus Greipel second and Luciano Burti coming in third. In 2006, Volkswagen entered in the series with the Bora and the championship adopted a point system similar to the one used in NASCAR, as well as a new system with 16 teams and 32 drivers. At the end of the season, the 10 best drivers were automatically qualified to run the 4 final races, called Super Final, similar to the Chase for the Sprint Cup. The 2007 season marked the largest amount of manufacturers competing
