Cooper-Maserati

Origins

By the end of 1965 Coventry Climax had withdrawn from Formula 1, leaving Cooper without a competitive engine just as the new 3-litre formula approached for 1966. The Cooper-Maserati partnership was the response: the Modenese marque dusted off a stretched version of its old V12 sports-car engine, and Cooper built a chassis around it. The hope was that a 3-litre, twelve-cylinder powerplant from one of Italy's great names would be enough to keep the Surbiton constructor in contention against the new Repco-Brabham, Ferrari and BRM threats.

Golden Era

The peak was John Surtees's victory in the 1966 Mexican Grand Prix in a Cooper-Maserati T81 — the first 3-litre formula win for Cooper, and the only Cooper-Maserati victory in the World Championship. Pedro Rodríguez added another the following season, winning the 1967 South African Grand Prix at Kyalami after a measured race that survived the works Brabham and Lotus retirements. Beyond those two wins the partnership was occasionally on the podium — Jochen Rindt was third at the 1966 Belgian and 1967 Belgian Grand Prix in works cars — but it was never genuinely championship-class.

Legendary Cars

The T81 of 1966 was Cooper's first 3-litre car: heavy, with the long Maserati V12 stretching the wheelbase, but handsome and capable in mixed conditions. The T81B updated the chassis for 1967, and the T86 of late 1967 with a lighter monocoque represented Cooper's best 3-litre effort — though by then the team's underlying decline was visible. A separate T86B with BRM V12 power followed in 1968 once the Maserati partnership ended.

Lows and Reinventions

The Maserati V12 was elderly, heavy and increasingly outclassed by the Ford-Cosworth DFV from 1967 onwards. Cooper's chassis department was running down even as the engine partnership produced fewer competitive results. The marriage formally ended at the conclusion of 1967; Cooper switched to BRM power for 1968 and finally to Alfa Romeo in 1969 before withdrawing entirely after that season.

Modern Era

The Cooper-Maserati cars are remembered as graceful late-period chassis from a once-dominant constructor that had been overtaken by the rear-engined revolution it had itself launched. The Mexico 1966 and South Africa 1967 wins are the documented peaks of the partnership; the rest is a slow descent toward Cooper's eventual exit. Restored T81s remain favourites at Goodwood and at historic Italian events, where the Maserati badge on a British rear-engined Grand Prix car still draws attention as one of the more unusual marriages of the 1960s.
