Ferrari 735 S

The Ferrari Monza is one of a series of cars built by Ferrari. In the early 1950s, Ferrari shifted from using the compact Gioacchino Colombo-designed V12 engine in its smallest class of sports racers to a line of four-cylinder engines designed by Aurelio Lampredi. Inspired by the success of the light and reliable 2.5 L 553 F1 car, the four-cylinder sports racers competed successfully through the late 1950s, culminating with the famed 500 Mondial and 750 Monza.

V12 models used downdraft carburettors located centrally in the "valley" of the engine, while the inline-engined fours used side-draft units and thus did not need the hood scoops.

Almost all Monzas had of wheelbase, except for 250 and 860 Monza.

1953

1953 was a breakout year for Ferrari, beginning with the new World Sportscar Championship series. The company augmented their traditional V12-powered 250 MM with the new 340 MM and 375 MM and introduced the new four-cylinder 625 TF and 735 S models. With this profusion of cars, Ferrari was able to sweep the first running of the sportscar championship.

625 TF

The first four-cylinder closed-wheel sports racer from Ferrari was the 625 TF of 1953. Resembling the Vignale-designed 250 MM spyder in most respects, the 625 TF used a 2.5 L (2498 cc/152 in³) straight-4 lifted from the 625 F1 car instead of the 250's 3.0 L V12. It was a small car, with the same 2,250 mm (89 in) wheelbase as the 250 but even lighter at 730 kg (1,610 lb). The engine produced 220 hp (164 kW) at 7,000 rpm and could push the little roadster to over 240 km/h (150 mph).

The lightweight car debuted at the hands of Mike Hawthorn at Monza on June 29, 1953. Although it could not keep up on the long straights at that track, Hawthorn still brought the car to fourth place at its debut.

A single closed 625 TF berlinetta, one of the last Ferraris designed and built by Vignale, was created in the Spring of 1953. Per Giulio Vignale, it was destroyed in a fire. There is speculation it was rebodied as a Spyder by Scaglietti in 1954 but this is unconfirmed.

735 S

The same day that the 625 TF debuted, another car was fielded for Alberto Ascari. Sporting an enlarged 2.9 L (2941.66 cc/179 in³) engine, Ascari's 735 S was more capable at Monza, leading the race until he collided with a 250 MM. The 735 S was a barchetta bodied by Carrozzeria Autodromo with recessed headlights, a drooping grille, and fender vents. Pinin Farina and Scaglietti also bodied an example each.

500 Mondial

The early experiments with Lampredi's four-cylinder engine led to the creation of the famed 500 Mondial. Named to mark the world ("Mondial") championships won by Alberto Ascari, the 500 Mondial featured a 2.0 L version of Lampredi's four-cylinder engine in a small and light body with an advanced suspension. The car debuted on December 20, 1953 at the 12 Hours of Casablanca driven by Ascari and Luigi Villoresi, placing second to a 375 MM. In 1954 four 500 Mondials were entered in Mille Miglia race, with best result being second overall after Lancia D24. The Mondial remained competitive through the end of the decade, including an entry in the 1957 Mille Miglia, and was raced as late as 1962, when Javier Valesquez entered chassis 0448MD in the 1962 Carrera Presidential race in Mexico City.

The 500 Mondial's 2.0 L (1984.86 cc/121 in³) engine was taken from the 500 F2 which won the world championship but was detuned to produce 170 hp (127 kW). It was extremely light at 720 kg (1,590 lb). and handled well with a modern de Dion tube rear suspension.

The first 500 Mondials were spiders bodied by Pinin Farina, but Carrozzeria Scaglietti later created a series of barchettas. Two berlinettas were also built by Pinin Farina. 29 were built in total. Of the 13 Pininfarina spiders built, 5 were the earlier Series I version with covered headlights.

The car won the prestigious Gran Turismo Trophy at the 2012 Pebble Beach Concours d'Elegance, meaning it will eventually be re-created for use in Gran Turismo 6.

1954–1955

The 1954 and 1955 seasons were the heyday of the four-cylinder Ferrari sports racer. The company hit its stride, earning the World Sportscar Championship in 1954 and contending in 1955 despite the legendary Mercedes-Benz team. The Ferrari sports car lineup at the beginning of 1954 was made up of the 2.0 L 500 Mondial and 3.0 L 750 Monza. The team replaced the Mondial with the 500 TR later that year, and feverishly worked to hold off Mercedes-Benz, developing the larger 857 S and six-cylinder 118 LM and 121 LM. The planned V12 sports racer family, including the 250 Monza of 1954 and planned 410 S of 1955, were less notable.

750 Monza

1954 saw the introduction of a new four-cylinder sports racer, the 750 Monza. Sporting a three-litre version of the 500 Mondial's engine, the Monza was much more powerful, with 260 PS (191 kW) available, but barely heavier at 760 kg (1,675 lb). The new-style body was penned by Pinin Farina and presaged the droop-nose look of the famed 250 GTO, but it was Scaglietti's 750 Monza, with its faired-in headrest suggesting the flowing Testa Rossa that drew attention.

Alberto Ascari was killed in the car during an impromptu testing session at Monza in 1955.

Mike Hawthorn and Umberto Maglioli piloted their 750 Monza to victory at Monza
on its very first race, giving the car its name. Although they were strong on the track, the Monza was unable to hold off the Mercedes-Benz 300 SLR in 1955, allowing the Germans to seize the sports car championship that Ferrari claimed in 1954.Museo Ferrari
