The 1966 changes in Formula One regulations, which impacted Formula 2, led Ferrari to collaborate with Fiat in producing a sports car to meet new homologation requirements of 500 production engine units. Fiat produced the Dino engine in coupé and spider forms under the name Fiat Dino. This facilitated Ferrari's introduction of the Dino 166 F2 for the 1967 European Championship season, featuring a rear-mounted 1,596.25 cc Dino V6 engine. The car debuted at the Turin Racing Car Show in February 1967. The engine initially produced 200 PS at 10,000 rpm, later increased to 232 PS at 11,000 rpm, with Lucas indirect injection and Magneti Marelli ignition. The chassis was a semi-monocoque with independent suspension and disc brakes. A total of seven cars were built, with three later modified for the Tasman race series with 2.4-litre engines. Driven by Ernesto Brambilla, Chris Amon, Andrea de Adamich, and Derek Bell, the Dino 166 F2 achieved its first wins in 1968 at the Hockenheim race and the GP Roma at Vallelunga.
