In 1968 Alfa Romeo acquired a controlling share in the FNM business: the next year the FNM 2000 was replaced by a restyled version, the FNM 2150, the most obvious visual differences affecting the front of the car. For this application the twin camshaft four cylinder engine saw its capacity increased to 2132 cc, and performance was further enhanced by the installation of a five speed gear box in place of the (at that time still more usual with Italian style passenger cars) four speed one of the 2000. The FNM 2150 would continue in production from 1969 till 1974.
