The reigning British Formula Three champion will be missing from this month's Macau Grand Prix for the first time in the race's history. Brazilian-born Mario Haberfeld would have been a force in the Macau race on November 22 for Paul Stewart Racing (PSR) but the 22-year-old Cambridge-based driver will attend Formula 3000 testing instead. It is the first time a reigning British Formula Three champion will not attend the Macau race since the Grand Prix became a Formula Three showpiece in 1983 - the same year the late Ayrton Senna won the race. Reports also suggest that Haberfeld will not race in Macau because he had 'little to gain' since winning the British title. But a local racing official said: 'This is purely speculative. The economic situation is really to blame. 'The Macau Grand Prix is regarded as the World Cup of Formula Three racing, so he had everything to gain.' It is understood that Haberfeld could not find a sponsor for Macau and will be replaced by fellow Brazilian Ricardo Mauricio - seventh in the British series. Drivers who have competed in the British Formula Three championship, one of the most prestigious in the world, have always done well in Macau. Recently crowned Formula One champion Mika Hakkinen of Finland was British F3 champion in 1990, the same year he crashed out of the race in the infamous clash with Michael Schumacher in Macau. Former Formula One champion Damon Hill finished third in the British F3 in 1988 before winning in Macau the same year, and David Coulthard is an ex-Macau winner, having finished second in Britain in 1991. Other drivers who have done well in Britain before venturing to race in Macau are Eddie Irvine and Danish Formula One star Jan Magnussen. Despite the absence of Haberfeld, the Macau race still boasts the presence of the Italian, French, Germany and Japan F3 champions.
