It's apparently a Cisitalia 202 SC. I've never heard of it either, or seen one before. It's stunning though.

Throughout the 1930s, Turinese texile industrialist Piero Dusio indulged his passion for motorsport. After winning his class on the 1937 Mille Miglia, he began to explore the possibilities of building his own racing cars. It was the racing variant, the 202 Spyder, which would write one of the greatest legends in motorsport at the 1947 Mille Miglia, Tazio Nuvolari, ( to me the greatest driver of all time)f, wrung a mighty performance from the little Cisitalia against the more powerful Alfa Romeo of Biondetti. Although suffering from the respiratory disease that would ultimately claim his life, the “Flying Mantuan” put in one of his most mesmerizing performances at the head of Cisitalia’s three-car works team.
