F2 went into decline with the arrival of the 2.5 L F1 in 1954 (with small-capacity sports car racing becoming particularly popular), but a new Formula Two was introduced for 1957, for 1.5 L cars. This became dominated by rear-engined Coopers drawing on their [[Formula 3]] and "Bobtail" sports car, with [[Porsche]]s based on their RSK sports cars enjoying some success. [[Ferrari]] originally developed their "Sharknose" [[Dino (automobile)#Dino 156 F2|Dino 156]] as a Formula Two car, while still racing front-engined Grand Prix cars. The dominant engine of this formula was the [[Coventry-Climax#FPF|Coventry Climax FPF]] four-cylinder, with the rare [[Borgward]] sixteen-valve unit enjoying some success.

A slightly enlarged version of the F2 [[Cooper Car Company|Cooper]] won the first two Formula One Grands Prix in 1958, marking the beginning of the rear-engined era in Formula One. The 1.5 L formula was short-lived, with [[Formula Junior]] effectively replacing first Formula Three and then Formula Two until 1963—but the 1961 1.5 L Formula One was effectively a continuation of this Formula Two. For 1960, in preparation for the new Formula One, two international championships were held, the [[1960 Formula Two season|Formula Two Constructors' Championship and the Formula Two Drivers' Championship]]. The Drivers' Championship was won by [[Jack Brabham]], while the Manufacturers' Championship ended in a tie between Porsche and Cooper.<ref>{{cite book |title=Autocourse Review of International Motor Sport 1960 Part Two |date=1961 |pages=110–122}}</ref>
