1961 Porsche 718 RS61 Spyder
The 1961 Porsche RS was one of the last Spyders made by Porsche that used the potent 4-cam engine. It was a successor to the 1960 RS60 which was a highly developed version of the original 550 RS Spyder. These diminutive racecars excelled on the tighter courses like the Targa Florio which was first won by Porsche in 1956.
That victory marked the first time a sports car with a midship engine had won a major motor sports event. Afterward Porsche continued with the successful design and updated the 550A RS into the lower 718 RSK. It was updated in 1960 to the 718 RS60 which under FIA-imposed rules had a larger interior space, taller windshield and larger doors. The 1961 version was built from this lineage.
After a successful year, Porsche continued to offer the RS 60 and changed its name to the RS 61. Completely identical in specification to the RS 60, it raced alongside the W-RS which had a more extended nose. In 1963, the factory released detailed documents on how to upgrade the Type 547/4 and Type 547/5 and gain an increase of about 10 bhp. Only 14 RS61s were produced.
