The last year of the 2.5 litre formula produced repeat victories for Jack Brabham and Cooper, and saw Lotus, Porsche, and BRM campaigning rear-engined cars. Lance Reventlow's Scarabs, like the Aston Martins, were front-engined and outclassed. Stirling Moss' Rob Walker Lotus gave Colin Chapman his first Grand Prix win at Monaco and followed it with a victory in the USA. All other Grands Prix went to Cooper, except for the Italian which was boycotted by the British constructors since the Italians were using Monza's banked circuit.
