Question
I would like to know if these motors are fuel injected and what horsepower are they? Are they air-cooled engines?

Answer
At launch in 1968, the 411 featured a 1679 cc twin carbureted engine. A year later, in 1969, fuel injection was introduced increasing horsepower from 68 to 80 bhp. In Europe, fuel injection was indicated by the suffix letter 'E' (for Einspritzung# in the model nomenclature, and the 411E's 80 bhp #60 kW# engine was shared with the mid-engined Porsche 914 also launched in 1969.
