1973 PORSCHE 911 RSR | The Greatest Car Ever Built

1973 Porsche 911 RSR

I just saw an interesting question posted by the official Porsche page on Facebook. In it they asked, “What’s the greatest RS of all times?  We want to know what you think!”.  Honestly, I really DO want to know what you think?  After seeing that, we just simply could not resist the temptation any longer to write about what I consider to be the best Porsche ever to come out of the factory floor, albeit in limited production.

I’ll admit right off the bat that I have a soft spot for older Porsches with a more classic look. I love the 356 Porsche Speedster and perhaps I even talk about it more than the car I am about to salivate over. But if I am honest with myself, and we should all strive to be, the 1973 Porsche 911 RSR is just simply automotive perfection.

Now I realize that I am not alone in my sentiment.  This is one of the things I firmly believe in that seems to fall within the category of general consensus.

“The Carrera RSR was the super star of the 1973 sports car racing season. Boasting 300 horsepower at 8,000 RPMs from its 2.8-liter flat six, it was another giant-killing, lightweight 911 based Porsche masterpiece. An RSR won the 24-Hours of Daytona, ahead of prototype efforts from Ferrari, Matra & Mirage-Ford. This is thought to be the most original, correct and lowest mileage RSR with race history in the world.”

Not only is the 1973 RSR the one of the most successful of the Porsche racers of all time, even leaving prototypes in the dust, it just oozes Porsche excellence.  If I had to describe the essence of Porsche to some alien life form, or place one image of the brand into a time capsule for future generations to discover, I’d show them an image of the RSR.

Although I have not ever driven one, nor have I ridden in one, I have seen several of them up close. And I have also heard their engines. Based on the articles I have read about them, and on their concept of a lightweight race car for the street, and on its record in racing, I must concur with you. This is a basic, pure car, a performance car, a beautiful car, an eye-popping car!!! The reverence with which it is spoken about, the desirability of owning one for every enthusiast’s garage combine with its heritage, its lasting appeal and with its “ahead of its time” performace to make it a complete car, the best in history!!

I too find a kind of excellence regarding them. They are very different than other race cars thus being one you could (with enough money and mechanics) build. Even better… they look so great. I would drive one in minute. Where are some keys?

The ’73 911 2.8 RSR is absolutely the most brutal vehical I have ever experienced and while I thrilled to the outrageous noise, mechanical inrimicy and explosive hook-up after the apex the driver wasn’t having near as much fun as the guy dancing the mid ’50′s AC Ace around corners and straights for giggles. But the most complete Sportscar I’ve been fortunate to experience is without doubt the 1961 Ferrari 250 SWB “SEFAC 61″. Not quite the power to weight of the RSR and a less electrifying experience but so much more controlable and fairly succesful in competition too.
