The Cooper T90 was a Formula 5000 race car built by the British racing team Cooper in 1969.
"A production line of 24 cars was launched, and one may expect that the Cooper-Chevrolet T90 will be a huge success."
This announcement was published in 1969. Only two T90s were produced. Both vehicles, the basis of the Cooper T86 were introduced in early 1969 in various race car exhibitions.
When in June 1969 Cooper stopped the racing, the two T90s sold with the remaining inventory. Until the early 1970s, one of them was run and adapted several times, being used by private teams in the British Formula 5000 Championship.
