Ford Pinto engine
It was used in many European Ford cars and was exported to the United States to be used in the Ford Pinto, a successful subcompact car of the 1970s, hence the name which is used most often for the unit. In Britain, it is commonly used in many kit cars and hot rods, especially in the 2 litre size.

Before final sign-off of the 1972 Pinto, in April 1971 Harold MacDonald, Ford vice president of car engineering, chaired a product review meeting around a report from Ford engineers. The recommendation suggested deferring from 1974 to 1976 the incorporation into all Ford cars of either a shock absorbent "flak suit" to protect the fuel tank at a cost of $4 per car, or a nylon bladder within the tank at a cost of $5.25 to $8 per car. Agreeing to the decision would allow Ford to realize a savings of $10.9 million. MacDonald agreed to the report's recommendation, and hence left the Pinto exposed to rear-end collisions.
