Made by Italian company ATS (Automobili Turismo e Sport) in Bologna, designed by former Bertone designer Franco Scaglione. Powered by a V8 engine, it was the first Italian and one of the first GT or sports car in the world to have a mid-engine layout.
The group behind the ATS project consisted mainly of Ferrari defectors, including key engineers Giotto Bizzarrini and Carlo Chiti, where family troubles in 1961 had created an uncomfortable working atmosphere for the personnel.
Only less than 20 were built before the factory closed down. (wikipedia & ultimatecarpage.com)
