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:
1948 Ferrari 166 F2 — Formula Two racer
1948 Ferrari 166 S Allemano — racing barchetta and coupé
1948 Ferrari 166 SC — motorcycle-fender Corsa racing roadster
1948 Ferrari 166 MM Touring — Superleggera racing barchetta and coupe
1949 Ferrari 166 MM Zagato — Racing barchetta and coupe
1949 Ferrari 166 Inter — Coachbuilt street coupe and cabriolet
1949 Ferrari 166 FL — Formula Libre racer
1953 Ferrari-Abarth 166 MM/53 — Racing barchetta and coupe
The 1965 Ferrari Dino 166P used a 1,6 L V6 engine.
