The six-wheeled 312T6 used four tyres at the rear, specially developed for the purpose. <br />It was one of a few six-wheeled designs during that period, although Tyrrell's P34 was <br />the only example which raced. The car followed in the footsteps of the Tyrrell P34, <br />but instead of four smaller front wheels, the T6 used 4 normal sized rear wheels on one rear axle.<br />The car was tested by both Niki Lauda and Carlos Reutemann in 1977, but it never raced. <br />Quite apart from the fact that it was far wider than the regulations permitted it also proved a<br />challenge to drive. During one test session at Ferrari's Fiorano test track, Carlos Reutemann, <br />on the 12th lap, crashed the car, which then burst into flames. On another occasion, <br />it suffered a rear upright failure.<br />Reutemann was not impressed with the 312T6.
