The third T86 built in 1968 was a special 'C' specification car made for a 3.0-litre Alfa Romeo V8 engine as used in the Tipo 33 sportscar, with an eye to Cooper using the Alfa engine in future instead of the BRM. Lucien Bianchi was entered in the car at Brands Hatch and Monza but did not take part in either meeting, Alfa Romeo withdrawing their support when it became clear in testing that the V8 was badly underpowered, with subsequent developments failing on the test bench.[4] Alfa Romeo did eventually enter F1 with the V8 with McLaren in 1970 and March in 1971.
