9113600121

according to registration ... this vehicle is that chassis. On the other hand, I have been assured that the vehicle in the photo is an SC with chassis number SC. If we look for the registration in Spain of the vehicle in the image we refer to chassis 121. RS.
With this I want to leave a note about this chassis since it seems that this or was registered in Spain with the registration h0797bbc (historical vehicle) that the chassis corresponds to the image. According to what they tell me, no ... Does anyone know of the existence of 121?




I do not add it to the post of the RS since it is not clear.

the 1973 RS officially WERE designated as "SC". If you look at the data plate of that other one you posted about (0038) the type number is 911SC (for carerra) see picture

so for registration purposes it would be absolutely correct to register a RS as a "911 SC" model

I have never seen any record of this car in the 30+ years i have have been collecting data on them but I only have information on about 900 of the RS's so am not surprised to see a new one crop up.

I would like to see more of this one before I could say whether I thought it was real or not though - 0121 was built with a sunroof for example and the photo is not at the right angle to see if there is one there

thanks HughH! You can tell what the SC designation is due to ... Sorry for such a "noob" question
I do not appreciate it in the image but if I had to say ... I would say that this vehicle does not have a sunroof ... In Spain, they are enemies of sunroofs for rallies or tracks ...

It is said the addition of the C to make it SC was to position the limited edition homologation special Carrera RS model (911.744) as an evolution of the current S so it could piggyback on some of the approvals in place for the 911 S. Important tactic as the timescale to make necessary 500 ahead of 73 racing season was short especially if same things had to be done completely from scratch. Probably saved money too as not cost effective to pass them from scratch for a model they was originally planned for a series of just 500. Quite what it piggybacked is not clear to me maybe crash testing whilst the RS the homolgation 500 plus 500 more weighed had about a dozen thinner gauge steel panels at various points throughout the monocoque possibly still sufficiently similar in key areas to go through as S variant? The RS wasn’t officially sold in USA so the few there had to have a notorised letter saying not for use on road on that country so maybe the SC ruse didn’t cover whatever USA required. Or it wasn’t sold there for other (regulatory) reasons. Certainly the RS didn’t get some of the USA market safety bits sms bobs that were arriving during model 73 like seatbelt buzzers, door strengthening etc. Don’t know all details of how adding C finessed the approval but could be that stuff was not ok for cars that had to meet 900kg at scales or possibly the reason for avoiding USA was 2.7 system emissions although quite similar to S different specs on details for RS not worth the bother given the timescales for plan for 500?

When I worked in the automotive engineering business there were specialist folks in our engineering team who could navigate such details and advise us as directors. I expect Porsche had folks who knew how to tiptoe skilfully through the whole vehicle NPD complexities of making multiple variants / configurations to be sold in multiple markets even when faced with ever changing regional regulations. They got homolgation for Gp3&4 for RS by early April. On time for some ( bit not all remember Daytona 24 hr M491 was entered as protoype) of the season so seems the addition of C might’ve helped. The very different 911 SC sold much later does sometimes confuse those not familiar with the add a C tactic on the 73 RS

My RS was imported from Italy in 2002 and when the Dutch authorities licensed the car, the paperwork that came with the license plate said 2.7 S. Originally, Porsche had the idea to name the car 2.7 S...
