Book excerpt: Little Book of the Audi Quattro is a 128-page hardback book written by Stan Fowler and Charlotte Morgan. Developed using four wheel drive technology, the Audi quattro stands out as one of the most revolutionary sports cars ever built. From its debut in the 1980s, the quattro was set to steal the show and it went on to do just that both on and off road. Today, it is a much loved classic with fans and quattro enthusiasts the world over. Originally, Audi had intended to produce just 400 quattros to be used in rally driving, but in the end, nearly 11,500 vehicles were built for a hungry export market. The car was unveiled at the Geneva Motor Show in March 1980 and as the first four-wheel drive grand tourer since 1966 it caused a sensation. The car became one of the most significant rally cars of all time when it was one of the first to take advantage of the changed rules in competition racing allowing a four-wheel drive to participate. Critics were sceptical that a four-wheel drive could achieve as near as much momentum, power and versatility. They were to be proved wrong.
