    1974 Carrera USA Info Thread

    There seems to be some interest on the board lately about these cars and my hope is that this thread can be the repository for information specific to the USA 1974 Carrera. I'll start it out with a paper I have been working on for quite some time regarding the performance of these cars. I think I've now collected and reviewed every contemporaneous publication that tested these cars. This started as a bunch of handwritten notes for my own education as I tried to reconcile all sorts of conflicting information regarding these cars.

    Perhaps more interesting than the performance data itself was what I learned about the large differences in testing methods utilized by Porsche and the various magazines.

    This is in PDF format and I don't think it can be posted here directly, so here's the link. It should open right up in Google Docs.

    Brilliant article! Finally an objective and well-researched look into a great year and a great car. I've grown tired of everyone parroting negative comments about these cars with no actual seat time in a '74S/Carrera.

    In the course of your research did you find any big differences between the '74S and the '74 US Carrera besides asthetics? From all the digging I've done the '74S has the exact same suspension as the Carrera (engine too, but that's a known tid-bit).

    Nicely done.

    Thanks Nate. I didn't look at that at all. But C&D did test a 911S Targa and it was just fractionally slower (0-60MPH = 5.9s, 1/4 mile = 14.6, top speed = 129MPH). Engine, final drive ratio and gearing is the same. The only variables would seem to be added weight of the Targa and aerodynamics?

    I'm going to steal some info from Mark's excellent 74 Carrera restoration thread here: 1974 Carrera Restoration - Family Owned Since 1975

    RE: Rubber Chin Spoiler

    There's discrepancy on this. Some sources say the chin spoiler was phased in at the end of the 74 Carrera production cycle. This doesn't make sense to me as the purpose was to balance out the larger 75 Carrera 'whale tail'.

    RE: Weltmeister window stickers

    It appears that the early 74 Carreras used the "1973" sticker ("Gewinnt CanAm & Interserie 1972"). At some point, a new sticker was produced signifying "Gewinnt CanAm & Interserie 1972 & 1973". Since the Interserie finished in late September 1973 and the CanAm season finished up in late October 1973, the changeover was probably around October since they clinched the title sometime earlier.
