A 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. One important stylistic difference between most four-cylinder Ferraris is that they lacked the hood scoops common on V12 models. The V12 cars 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. ==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 barchetta 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 2250 mm (89 in) wheelbase as the 250 but even lighter at 730 kg (1610 lb). The engine produced 220 hp (164 kW) at 7000 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 coupe, one of the last Ferraris designed and built by Vignale, was created in the Spring of 1953. ===735 S=== The same day that the 625 TF debuted, another car was fielded for Alberto Ascari. Sporting an enlarged 2.9 L (2942 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrari Monza」の詳細全文を読む スポンサード リンク
