Count Carlo Felice Trossi di Pian Villar (27 April 1908 – 9 May 1949) was an Italian racing driver and auto constructor.

During Trossi's career, he raced for three different teams: Mercedes-Benz, Alfa Romeo and, briefly, Maserati.

It featured a 16-cylinder, two-stroke cycle, two-row radial, air-cooled engine and an aircraft-like body designed by Augusto Monaco.

[3] Trossi had many exciting hobbies: racing boats and airplanes in addition to cars.

Enzo Ferrari said of Trossi: "He was a great racer but never wanted to make the effort to reach a dominant position and I remember him with emotion since he was one of the first to believe in my scuderia of which he was a part".
