You forgot the supercar "Pagani" from Italy that offers even higher performance than the others you mentioned. When I visited a new Italian partner, he arranged a private, after hours tour of Pagani which led to my being interviewed by the "Robb Report".
Of course Ferrari designs some true, high performance autos...but doesn't come close to Bugatti Chiron in engineering, performance, styling & luxury.
btw, here's the Pagani "Huayra" Roadster...
