It was the Tipo 166, introduced in 1948 as a replacement for the 125 S, that first established Enzo Ferrari’s Modenese workshop as a leading manufacturer of racing cars. Powered by a 2-liter, Colombo-designed V12 engine, the 166 set forward a course of development that would define the look, sound […]

1967 Ferrari 412P

The era was perfectly encapsulated by Sir Jackie Stewart as being “when sex was safe and racing was dangerous.” Ferrari and Fantuzzi, aided by the Maranello marque’s genius in-house stylist Edmondo Casoli (aka “the father of the 250 GTO”) created one of the most sexy, most beautiful pieces of performance […]

The advanced 3,747-cc engine found a home in the 118 LM — a sports car designed to […]
