Trossi backed one of the most unusual Grand Prix cars, the Trossi-Monaco of 1935. It featured a 16-cylinder, two-stroke cycle, two-row radial, air-cooled engine and an aircraft-like body designed by Augusto Monaco. The car was a spectacular failure and never raced in a Grand Prix event.[3]
Trossi had many exciting hobbies: racing boats and airplanes in addition to cars. He was also the president of the Scuderia Ferrari in 1932.
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".[4][better source needed]
