The 1956/7 500 TRC was a massaged version of the successful 500 TR of the previous year. In keeping with the new C-section regulations, Ferrari widened the cockpit, added doors, fitted a windscreen, and even added a stowable convertible top. It rode on the longer 2350 mm (93 in) wheelbase of the 860 Monza and featured coil springs all around, though the live axle in the rear was retained rather than the more modern de Dion tube. The 680 kg (1500 lb) car's 180 hp (142 kW) made it quite capable, and even though it was never a works car, a 500 TRC was 7th overall, claiming class victory at the 1957 24 Hours of Le Mans.

In the early part of the fifties the Ferrari worked and basically developed two types of racing engines: the four-cylinder designed by Aurelio Lampredi and V12 of Gioacchino Colombo . These two types possessed characteristics that made them preferable according to the degree of development. One of them was the consumption of fuel , in fact the first was less "thirsty" compared to the second.
A series of developments led to the construction of various evolutions, with different displacements, the in-line four-cylinder engine that was mounted on various Ferrari models, including the TF 625 , the 735 S , the 750 Monza and the 860 Monza . In recent years the Maserati dominated many races, and Ferrari decided to further develop this type of engine coming to that fitted to the 500 TR , which was designed by Vittorio Jano . Later it was prepared the in-line four-cylinder engine that was fitted to the 625 LM and that derived from that of the 625 F1 . Finally he reached the 500 TRC, which was the last to mount a Ferrari engine with four cylinders in line. It was 2L and originated more or less directly than those mentioned above.
