924 was purely marketing, it was picked for it's relation to 928. The project that became the 924 was called EA425 and was a joint VW and Porsche project (VW wanted their next sports car to follow on to the 914) designed by Porsche using Audi (motor, tranny) and VW (super beetle rear suspension!) parts, and was paid for by VW with the plan of it being an Audi sports car. Then VW canned the project. Porsche decided to take over the car and pay back VW for their development costs. Porsche wanted to create a low end car where porsche could control quality. (the 914 was built without any porsche quality control) When it came time to name it they picked 924, to go with the 928 which were seen by porsche as part of a next generation of cars, water cooled, front engined, and transaxled.

all of the above is from Ludvigsen's Excellence was Expected, which is one heck of a christmas gift.

Can anyone find an orgin for the 928 type in Excellence was Expected? Best I can tell it was a valid numeric progression for the start of the program around 1970. Excellence mentions the 'H-program' but there isn't any thing in the index for that term...

My 1989 928 GT has the type designation 928 920.

What is the story behind the 920 ?

I have seen a 1990 GT with the designation 928 940.

What is the difference ?

More specific details on how car was ordered. There are 2-4 different variants for each MY.

I understand. But what is the diffference (apart from being 20) ?

I have seen 910, 920 (sunroof + manual) and now 940 (sunroof + manual). I guess we are talking major structural differences, or differences related to the production process. Sunroof, Airbag or manual vs. automatic transmission. There appears to be some chronology in this as well. I have only seen the 910 variant on pre-'87 cars and 94 on post-'90 cars. Others may have different experience.

We have seen examples of 927 indicating the car to be RHD (most likely), but this is obviously something different, probably less significant.

I think it means the 928 is 17 x more complex than the simple 911.

Another interesting designation is:

928/2746 1978-85 928-based aluminum body studies with Alusingen and Alusuisse. (see post #40 for a comprehensive list of designations).

This car is on display at the Porsche Museum and has previously been shown in Leipzig (in 2007). According to the information next to the car, when it was shown in Leipzig, it had the designation 928 D 49. See attached photo. At the museum it is just shown as a 928S.

See also the links to a scanned version of a presentation leaflet published by Alusingen / Alusuisse, the company who in cooperation with Porsche developed the project.

Observe that the car in the leaflet has phonedials, whereas the car in the museum has Club Sport rims. The car was manufactured in 1982 and the CS wheels are from 1988.

Is it the same car in the leaflet as in the museum ? I do not know, but I guess so, based on the photos of the front suspension, which can be found in this thread: https://rennlist.com/forums/928-forum/501106-porsche-museum-928-comment-there.html A picture in the leaflet, on page 3, shows the body without the R/H front wing (see attached picture) and here the different front suspension attachment points appear.

speculation is meaningless

I guess it means you can resurrect a thread that's was last commented on near 5 years ago

'89 S4 GP White/Black
'76 912e Silver/Black

On early cars its 4,5L vs S body, on GTS its automatic vs 5sp. In between it can be few other body related changes. Both LHD and RHD have their own pairs. In all there are 9 different possibilities over the years. 927 is RHD.

Random number,......no way. These are not US auto makers we are talking about! These are Germans!!! Noting is random!!!

Worth reviving because I stumbled across it looking for something else and it reminded me of a fun night with some neighbors where after some time the conversation turned to my explaining that the "8" in 928 was part of a Porsche coding system where the third number represented the number of cylinders. One of my neighbor's wives, with apparently a keen sense of smelling B.S., asked "Well, what about the 911?" Already committed and with nothing to grasp at I proceeded to explain how the 911 motor has only one cylinder and is known as a "thumper" motor, and further, it's performance comes from the many valves attached to that single cylinder. There was a pause while either incredulous shock or a slight suspension of disbelief was occurring, and then the cat was let out of the bag when I started to laugh. Good times!
