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.

Two cars were initially constructed, a third being built after Redman's crash at Spa,[2] and these were used exclusively by the Cooper works team during the 1968 Formula One season.

The chassis was later converted to F5000 spec with a 5-litre Ford V8 and entered in 11 events in the 1970 Guards European Formula 5000 Championship driven by Fred Place but was not very successful.

[5][6] The car has since been restored to its original form with a similar Alfa Romeo V8 to its intended powerplant, and appears regularly in historic racing.
