The 1971 started with a win by new signing Mario Andretti. Although being presented in January, the 312 B2 debuted only at the third round in Monaco, followed by the Dutch Grand Prix success for Ickx. However the B2 suffered with handling problems: the combination of the innovative rear suspension and the new Firestone tyres gave severe vibrations when driven close to the limit. Forghieri designed and fitted winglets to the front wings of the car for the British Grand Prix that year; however these were not seen again afterwards. Ferrari ultimately came third in the Constructors Championship, as Jackie Stewart and Tyrrell dominated the season.
