Chronology
SuccessorLancia Flat-4 engine

Italian automobile company Lancia was the first to manufacture cars with V4 and V6 engines in series-production. This started with a number of V4-engine families, that were produced from the 1920s through 1970s.

The Lancia V4 pioneered the narrow-angle V engine design, more recently seen in Volkswagen's VR5 and VR6 engines. By using very shallow V-angles — between 10° and 20° — both rows of cylinders could be housed in an engine block with a single cylinder head, like a straight engine. A determining characteristic was the use of overhead camshafts (either single or double), in which a camshaft would serve the same function for all cylinders — in both cylinder banks.
