カルロス・ロイテマン
The car was tested by both Niki Lauda and Carlos Reutemann in 1977, but it never raced. Quite apart from the fact that it was far wider than the regulations permitted it also proved a challenge to drive. During one test session at Ferrari's Fiorano test track, Carlos Reutemann, on the 12th lap, crashed the car, which then burst into flames. On another occasion, it suffered a rear upright failure. Reutemann was not impressed with the 312T6.
