==Development==
The T55 was a stop-gap development of the [[Cooper T53]] for the start of the [[1961 Formula One season]], pending the introduction of a new chassis to take the [[Coventry Climax|Climax]] FWMV V8 for the new 1.5 litre formula.

==Racing history==
The T55 debuted at the non-championship [[1961 Aintree 200]]. [[Jack Brabham]] and [[Bruce McLaren]] finished first and second, and Brabham set fastest lap. However, it would be unable to match the power of the new [[Ferrari 156]] in the World Championship events, where McLaren's third place at Monza would be its best result. Cooper would finish fourth in the Constructors' championship.

The works team continued with the T55 at the start of 1962, along with the V8-powered [[Cooper T60|T60]], primarily driven by Brabham's replacement [[Tony Maggs]], although McLaren used it in some non-championship events. [[John Love (racing driver)|John Love]] then obtained one of the cars and campaigned with it in several South African events, including its last World Championship appearance at the [[1965 South African Grand Prix]].<ref>{{Cite web|url=https://www.oldracingcars.com/cooper/t55/|title=Cooper T55 car-by-car histories|first=Allen|last=Brown|website=OldRacingCars.com}}</ref>

The Cooper-Climax T55 is a Formula One car built by the Cooper Car Company for the 1961 Formula One season. Its best result was third-place for Bruce McLaren at the 1961 Italian Grand Prix. [1][2][3]

Development

[edit]

The T55 was a stop-gap development of the Cooper T53 for the start of the 1961 Formula One season, pending the introduction of a new chassis to take the Climax FWMV V8 for the new 1.5 litre formula. Smaller and lighter than the T53, it was powered by the 170 hp (130 kW) naturally aspirated Coventry-Climax FPF four-cylinder engine driving through a new Cooper six-speed gearbox.[4][5]

Racing history

[edit]

The T55 debuted at the non-championship 1961 Aintree 200. Jack Brabham and Bruce McLaren finished first and second, and Brabham set fastest lap. However, it would be unable to match the power of the new Ferrari 156 in the World Championship events, where McLaren's third place at Monza would be its best result. Cooper would finish fourth in the Constructors' championship.

The works team continued with the T55 at the start of 1962, along with the V8-powered T60, primarily driven by Brabham's replacement Tony Maggs, although McLaren used it in some non-championship events. John Love then obtained one of the cars and campaigned with it in several South African events, including its last World Championship appearance at the 1965 South African Grand Prix.[6]
