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.
