The Cooper T51 was a Formula One and Formula Two racing car designed by Owen Maddock and built by the Cooper Car Company for the 1959 Formula One season. The T51 earned a significant place in motor racing history when Jack Brabham drove the car to become the first driver to win the World Championship of Drivers with an engine mounted behind them, in 1959. The T51 was raced in several configurations by various entrants until 1963 and in all no less than 38 drivers were entered to drive T51s in Grand Prix races.
The chassis
Aesthetically and aerodynamically, the T51 was a natural development of the
Engine and transmission
The standard F1 T51 was the first Cooper powered by the 2.5-litre 4-cylinder engine which Cooper and Lotus had commissioned Coventry Climax to build specifically for their rear-engined machines. The pioneering nature of this configuration created problems of its own, since there were so few rear-engined production cars from which a gearbox could be sourced. This shortage eventually created a niche in the market which paved the way for Hewland's prominence, but in the meantime many different solutions were tried, with varying degrees of success. The works Coopers were fitted with modified Citroen gearboxes, while Rob Walker's team ran bespoke units from Italian specialist Valerio Colotti, although these proved much more fragile.
In all, eight different engines were used in the back of T51s in championship races, with 2.2- and 1.5-litre Climax engines in addition to the standard 2.5: Scuderia Centro Sud and others used 2.5 and 1.5-litre engines from Maserati; the British Racing Partnership team used F2 powerplants from Borgward; Scuderia Eugenio Castellotti used their own Ferrari-derived 2.5-litre units; and one car used a Ferrari 2-litre engine lifted from a 625LM.
A historic season
The T51 had already won the
By the final race at Sebring Cooper already had the Constructors' Championship in the bag, but the Drivers Championship was still up for grabs. Moss needed to beat Brabham and finish second or better to take the title, while Ferrari's Tony Brooks had a mathematical chance but needed both the win and fastest lap. Moss sprinted into the lead from pole position with Brabham in pursuit. After five laps Moss was a commanding ten seconds ahead, before his gearbox gave way again. Brabham led right up to the final lap, when a poor decision on Brabham's part meant he ran out of fuel. He managed to push his car across the line in fourth, but Cooper still won the race as Bruce McLaren became the youngest winner in Formula One history (a record he held until surpassed by Fernando Alonso in 2003), leaving Brabham the Drivers' Champion.
Into obscurity
Cooper travelled down to the 1960 Argentine Grand Prix seemingly at the peak of their powers, and Trintignant won the Buenos Aires F1 event that preceded the main championship race. However this turned out to be the last major win for a T51, as the speed of the new Lotus 18 began to dominate. On the journey back, John Cooper made his mind up that to stay at the front he needed to build a new car, and at the next championship race at Monaco the lowline T53 made its debut. In the meantime Moss took the Walker T51 to second in the Glover Trophy and qualified on pole position for the International Trophy before retiring with wishbone failure. Rob Walker had already bought a Lotus 18 for Moss, but the Englishman was to miss a large part of the season through injuries sustained when his notoriously fragile Lotus lost a wheel at speed in Belgium. Cooper entered the T51 just three more times, with ex-Scarab driver Chuck Daigh and journeyman Ron Flockhart retiring each time.

Privateer entries
As well as being a racing team, Cooper was very much a business, as shown by the 1958 International Trophy where 19 Coopers of various types made up more than half the grid. Right from the outset the T51 was designed to be produced in large numbers and offered for sale to privateer teams, with Rob Walker getting full-works cars and the rest receiving slightly more workmanlike models. No fewer than ten other entrants ran T51s in Formula 1 during 1959, and with the works team switching to the T53, and Walker using Lotus 18s, many of the ex-works cars were sold and continued to be entered in 1960. Indeed, the T51 continued to appear on minor, non-championship F1 race entry lists as late as the 1967 Rhodesian Grand Prix.

British Racing Partnership/Yeoman Credit Racing Team
The British Racing Partnership team was founded by Ken Gregory and Alfred Moss, Stirling's father, in late 1957. They spent 1958 and 1959 competing in Formula Two events, with the odd entry into F1 races, particularly in the UK, and experimented with 1.5-litre Borgward engines for their 1959-spec T51s, under an arrangement whereby Stirling Moss would use the Borgward-engined BRP cars with Rob Walker as the entrant.
For 1960 they had agreed for the three Samengo-Turner brothers, motor racing enthusiasts who owned Yeoman Credit Ltd., to bankroll their season with 2.5-litre Climax-engined F1 entries as well as a full slate of F2 entries with Borgward. BRP's list of drivers for 1960 was quite impressive, including at various points future champions
By the end of 1960 BRP had lost three drivers - Ivor Bueb, Harry Schell (who also ran his own T51 under the Ecurie Bleue banner) and Chris Bristow - to fatal accidents, and the Samengo-Turners decided to take their money to Reg Parnell's team instead, and since Parnell had filled up Cooper's order book BRP had to switch to Lotus for 1961.

Scuderia Castellotti
Named after the Ferrari driver who died in testing at the Modena circuit in 1957, Scuderia Castellotti was founded by Giuseppe Corsi in Lodi in 1958. It used modified Ferrari Tipo 553 2.0-litre engines bored out to 2.5 litres and rebranded as "Castellotti", with "Eugenio" on the cam covers. The cars were easily distinguishable from other F1 T51s in that their exhausts were fitted on the left, while all other engines used in T51s had their exhausts on the right. The team competed in four events in 1960 with lesser-known Italian drivers Gino Munaron, Giorgio Scarlatti and Giulio Cabianca.
Cabianca scored the team's first championship points by finishing fourth at the 1960 Italian Grand Prix.
Cabianca was at the wheel of a T51-Castellotti in Modena in 1961 when he fell victim to one of Formula One's most bizarre accidents while testing. With his throttle stuck open he was unable to stop, went out of the circuit onto public roads and collided with four bystanders before crashing into the wall of the coachbuilder Orlandi. In the aftermath, the inadequacy of the Modena circuit's structures were lambasted in a court case, effectively preventing the track from running any further events.[1]

Other privateers
The T51 was entered into championship races by a further twelve organisations, the most notable being Reg Parnell, who later took over Yeoman Credit's racing activities from BRP, and Fred Armbruster, who entered Pete Lovely in the 1960 United States Grand Prix with a T51 uniquely fitted with a Ferrari Tipo 555 engine, a different engine to those used by Scuderia Eugenio Castelotti. The final World Championship appearance for a T51 came when Trevor Blokdyk took his Scuderia Lupini T51-Maserati to twelfth place in the 1963 South African Grand Prix.
