The Ferrari Dino was 6 cylinders, not 4 as has been stated. Originally a 2.0 liter (hence 206 nomenclature, 2.0L, 6 cylinders), later bored to 2.4L (246). For those that aren't Ferraristi, many of the non-12 cylinder engine cars in the Ferrari lineup (both customer car and Scuderia cars) were labelled "Dino" in honor of Enzo's son Alfredo "Dino" Ferrari. Alfredo studied Engineering in University, and it's long believed he suggested use of a 1.5L 6 cylinder engine for participation in F2 back in the 1950's. Unfortunately, Dino was stricken with MD, and died in 1956 at the age of 24. Hence, many of the smaller displacement/sub-12 cylinder cars were called Dinos. In fact, the original customer Dinos (the 206 models) were not intended to be Ferraris at all. Rather, they were a sub-brand, not unlike Toyota's Scion. The intent was not only for the 206/246 models to be Dinos, but the successor 308GTB/GTS! However, that changed for whatever reason and the Dino name passed into history. Today, the Imola circuit is named in honor of both - Autodromo Enzo e Dino Ferrari. Sorry to hijack, but I am a tifosi, had to correct there!
