The Cooper T86 was a Formula One racing car built by Cooper and first raced in 1967. B and C specification cars were also built to accommodate different engines, but the car could not revive Cooper's fortunes and this type represents the last Formula One chassis built and raced by the former champion team.
The Cooper T81 had proved rather successful when it first appeared in 1966 but by mid-1967 it had slipped behind the newer cars of the leading teams. The new T86 car was built for Cooper's lead driver Jochen Rindt to use, starting with the British Grand Prix, a narrower, lower and lighter car fabricated from Elektron alloys with a bump around the gear lever to give the driver more space while changing gear, a feature that became a common sight on single-seater cars well into the 1970s. The new chassis was some 112 lb lighter than the T81, but was still overweight due to its Maserati V12, an engine whose first incarnation had raced in Formula One in 2.5-litre form some ten years earlier. It was found that the car had a tendency to get light at the front at high speeds, but ahead of the Italian Grand Prix this was fixed by the mounting of a small spoiler on the nose, another innovative feature. Jacky Ickx drove the car at Watkins Glen, and former Grand Prix winner Ludovico Scarfiotti gave the car its last outing for the works team in the first race of 1968.
The car wasn't used for the remainder of 1968, and by 1969 it had been acquired by Colin Crabbe, who got Vic Elford in to drive the car for his appropriately named Antique Automobiles racing team in the International Trophy. Neil Corner drove the car at the non-championship Madrid Grand Prix but Elford came back for the Monaco Grand Prix where the car qualified last and finished last of those still running, 6 laps down in 7th place. It was to be the last time a Cooper was raced in a championship Grand Prix as Crabbe acquired the McLaren M7B for Elford to drive in later races.
