1955 Porsche 550\/4 RS 1500 Spyder #37<\/strong>

In the 1951 Le Mans race, Porsche made history with their first class win<\/a>. However, it was obvious that modified production cars were not the best way to win races. Consequently, right after the race they started the development of a purpose-built race car. That car was the Porsche 550<\/strong>, and by 1953 the first units came out of the Zuffenhausen plant. Though designed and produced for the tracks, the 550 was road legal, a detail that appealed to privateers. And even more importantly, the 550 was an awesome racing machine. Powering the 550 was the Typ 547<\/em> engine, designed by Ernst Fuhrmann. A 1498 cm\u00b3 boxer-4, it delivered 82 kW (110 hp). Not much, yet enough for the 550 kg car. In essence, the 550 was a brilliant project, achieving victories all over. At Le Mans, for instance, the 550 won in 1953<\/a> and 1954<\/a> (in two different classes!).<\/p>\n\n\n\n

The N\u00fcrburgring Eiffel Race, in May 1953, was the 550\u2019s inaugural race. And first victory.<\/figcaption><\/figure>\n\n\n\n
Despite the 550\u2019s undeniable success, in 1954 Porsche began further improving the car. Nothing radical, just small tweaks to the engine, body and chassis that would make it better overall. With the experience gained on tracks, for 1954 Porsche totally abandoned the coupe version, producing only spyders from then on. With that, Porsche called the \u201cnew\u201d 1954 model 550\/4 RS Spyder 1500<\/strong>. Though the production of the first 550 RS began in September, the car was only delivered in January of 1955. That happened because Porsche could not meet production demands, and also because development was occurring during<\/em> production. With the new car ready, Porsche arrived at Teloch\u00e9 in Le Mans with two factory cars. Adding to that, there were another three privateers, with a total of five<\/a> 550\/4 RS Spyder in the race. And once again the 550 dominated \u2013 just one of the privateers DNF.<\/p>\n\n\n\n

It is rare for a car model to dominate Le Mans like the 550 did in the 1950s.<\/figcaption><\/figure>\n\n\n\n
The two factory cars were 550\/4 RS #37 and #62. Car #37 came in first place<\/a> in the S 1.5 class, while #64 came in third, with a privateer in-between. In 1956 and 1957 the 550 won again (by then 550A\/4 RS). That equals to five class wins in five consecutive years. No wonder the 550 received the nickname Giant Killer<\/strong>. This 500\/4 RS Spyder #37 is the fifth<\/em> 550 in the W-143 Garage. I know it\u2019s starting to sound as \u201cmore of the same\u201d, yet without a doubt this is a hugely important car for Porsche (and Le Mans). Apart from the Porsche 956, I\u2019m hard-pressed to cite another car as successful at La Sarthe. <\/p>\n\n\n\n

Is five enough? Well, now with RS #37, probably \ud83d\ude09.<\/figcaption><\/figure>\n\n\n\n
A monster of a car on the racetrack, however I think I have enough 550s now \ud83d\ude01.<\/p>\n","protected":false},"excerpt":{"rendered":"
