1965→1973 AC 428

Unlike most cars by AC, The AC Frua was designed by Pietro Frua, instead of Caroll Shelby, of which it got it’s name from. This car is easily mixed up with the Maserati Mistral, but these two cars only share the front quarter view, the headlights and the slightly similar grille.

This car was extremely limited edition with only eighty one been made. It had a huge, seven litre big block V8 from the Ford Mustang of the time. Like most large, American V8s, the AC Frua tended to have the problem of heat leaking into the cabin.

From 1970 onwards to 1973 when production stopped, the AC Frua had 1 prototype made with electrically powered pop up headlights. It was planned for production but It was thought to be to expensive to make.
