He scored a total of 1.5 championship points, awarded for his fourth-place finish in the 1956 Argentine Grand Prix, a drive he shared with Gerino Gerini.

Landi came from a modest middle-class family of Italian origins, and got into racing through his father, who owned a garage in São Paulo.

Along with Manuel de Teffé and Irineu Corrêa, he popularized motor racing in Brazil in the late mid-thirties.

Landi had left school at eleven to work as a mechanic, and later began illegal street racing at nights, where he had frequent run-ins with the police.

When Corrêa, who ended up winning the 1934 Rio Grand Prix, died in a crash on the first lap of next year, Landi was left as the undisputed master of pre-war racing in Brazil.
