Lancia Flat-4 engine


Lancia, known for their advanced engineering, surprised the auto world by designing a new aluminum flat-4 engine for their 1961 Flavia. Though it was a pushrod engine, it was advanced for the time. The pushrod version of the Lancia boxer was only ever used in the Flavia. In the mid 1970s, an overhead cam engine based on a similar layout was designed and brought into production in 2 and 2.5 litre forms fitted to the Gamma.

The original version was the 1.5 L (1488 cc) 1500.

The 1.8 L 1800 was introduced in the mid-1960s. It used an 88mm bore and 74mm stroke and produced up to 102 hp (76 kW) with Kugelfischer mechanical fuel injection.

2000 (Pushrod)

The 2.0 L (1991 cc) 2000 version was the ultimate Flavia engine. Bore was 89mm and stroke was 80mm for a good oversquare ratio. This engine was produced from 1968 through 1974.
