The Ferrari Monza series, a pivotal development in Ferrari's early 1950s sports racers, marked a shift from the Gioacchino Colombo-designed V12 engine to a more robust line of four-cylinder engines by Aurelio Lampredi. On the same day the 625 TF made its debut, Ferrari also fielded the 735 S for Alberto Ascari. Equipped with a larger 2.9 L engine, Ascari's 735 S was more competitive at Monza, leading the race until a collision. The 735 S, a barchetta bodied by Carrozzeria Autodromo, featured distinct design elements such as recessed headlights, a drooping grille, and fender vents, with Pinin Farina and Scaglietti also creating a body each for this model.
