Pedro Chaves became the first Portuguese driver in Formula One for 27 years when he contested the 1991 Formula One season with the uncompetitive Scuderia Coloni team. Chaves failed to qualify for any of the thirteen Grands Prix he entered and left the championship before the first practice session of the 1991 Spanish Grand Prix over non-payments and a lack of testing from the Coloni team. After leaving Formula One Chaves established himself as a rally driver.
