Alfa Romeo boxer
Dubbed boxer due to the fact that its pistons are horizontally opposed, like a boxer’s fists, this Alfa engine is recognised as one of the most characterful ever made. Debuting in the Alfasud, it also speared in the Sprint and the Arna, and stuck around long enough to appear in the 33 and briefly the 145. The earlier carburretor versions were praised for their snappy response, keenness to rev and a glorious exhaust note.
