Ferrari used its 2 L (1995 cc/121 in3) V12 engine in a number of models, all called 166 for the displacement of a single cylinder. Most early 166es were sports cars built for racing, though a later line of GT cars launched the company's street model line.
The following models used the 166 name:
The 1965 Dino 166 P and 1967 Dino 166 F2 — a Formula Two used a 1,6 L V6 engine.
