We have all seen the image of a classic (pre impact bumper) 911 next to a somewhat bulbous looking later model - a 991.1 C4S (which is the same width as the 992, hence the interest here), I think (you can check it out here - https://www.topgear.com/car-news/heres-every-single-generation-porsche-911). I don’t know where the original image is, but this is the one that came up first when I searched for it.
With an interest in what has changed over the years, and possibly a bit too much time on my hands, I decided to research how the numbers have evolved over the years. Using the information readily available on the internet (which is an initial health warning) I collected the data on the attached pdf file (via a spreadsheet). I did try inserting the table in this message to no avail. Obviously I need still more time!
While there are qualifications to the data (see below) it does give a good idea to how things have changed.
Interestingly the data on the table shows the 991.1 (and 992) is 15% wider than the pre impact bumper model (be it a 1965 2.0 911 or a 1973 2.4 911S), whereas measuring the image above the newer model appears to be 21% wider. Is this a case of "photoshop engineering” somewhere in the life of the image?
Qualifications:
The data was collected from Excellence/Parkers/Wikipedia/Elferspot/Porsche Brochure and so may cover different specifications/markets/years.
The numbers may be on a different basis (e.g. Weight may be wet/dry), but I have tried to be consistent. Nevertheless a few errors are bound to have slipped through!
All numbers are (I believe!) for coupes and with manual gearboxes.
Turbo figures are for non S model.
It is not intended to cover all models!
