02Production & history

Production

Every figure says what it counts.

No production figures recorded yet.

History

Diatto was a Turin carmaker active between 1905 and 1929 that was later revived as a brand. The Ottovu was first shown as a Zagato concept at Geneva, and Zagato then announced the GT as a small production run.

The announcement described the car as an aluminium berlinetta planned for limited production. The engine was not named at the first announcement; later press gives a supercharged Ford-derived 4.6-litre V8.
