Porsche didn't "kill" the 914, VW did as they owed the Karmann plant and forced Porsche out as VW wanted the line for the new water cooled Scirroco. Porsche tried and failed to find a suitable affordable place to setup the line to keep production going but failed. The 76 MY cars bodies were made in 1975 and at the Christmas break the line was switched over to Scirroco producion. This is why Porsche came out with the 912E, to fill the gap in their line with a inexpensive car after the 914's were sold out. So you could add the 2100 912E cars to see about how many 76 914's should have sold. The question is how long would Porsche continue selling the 914 at 6-7000 cars a year? What would they have done to upgrade the model line "IF" VW hadn't pulled the assembly plant from under them...
Remember, Porsche fully owned the 914 from mid 74 as they had bought out VW at that time. They had plans for the 914 but when VW announced their plans in 1975 for the Karmann plant Porsches plans went up in smoke.
The 924 is another story as VW pulled out of the production of this car at the final moment and the Audi plant were the cars were going to be made came to Porsche with a sweetheart deal to distribute the cars as Porsches.

Okay - I got your point after the 4th one posted! ... twitchy finger I guess!?
I was aware the Porsche switched to the 924 after VW backed out & that before that they explored various options with the 914, but was not aware that they were booting the 914 from the Karmann plant to make room for Scirocco production.
I think that Porsche probably would've moved to the 924 though, even if they still had the Karmann plant's line available, because they wanted to try out water cooled.
What theneeded was to continue the 73 & 74 sales volume in the 20,000+ range, but the prices had just climbed too high by 75 to sell that many, plus we had a pretty bad recession here then too, depressing sales (as today).
One huge problem for all imported car makers were threatened tariffs, bad monetary exchange rates (for them importing), & the runaway inflation of the 70's, which had 76 914's selling for about what the 911s did when the 914s came out in 69/70! By 76 a 914-2L with the option cost for the AG & PG options was north of $8000 out here in CA, but smog detuned to 86 hp.
While in Fall 75 I could've gotten a new 76 2L on 100% loan vs. 75% used for my 73 2L & have about the same payments, I didn't like the big bumpers nor the lower power engine ~ & today I'd still be required to smog it every other year!
