How many cars made per month, roughly, in 1970?

[Scott A]

Hello,
Does anyone have an idea of how many 911s were being made per month in 1970?

Is it around 60? Two per day. Or more like 300? 10 per day.
Thanks.

according to the Peter Morgan Original Porsche 911 book, there were 14,266 911 coupes and targas made in total in the 1970 MY. including the 4575 made by Karmann. They had a couple of weeks off for summer break and retooling for the next model etc so lets say 11.5 months. Roughly that would be almost 1,250 a month - or if you said 47 weeks almost 300 a week. Obviously they would have started out a bit slower and then ramped up so probably on a good month (mid year long month with no holidays)there could have been about 1300 made so closer to 60 a day across both sites
for pure Porsche factory built Coupes there would have been almost 1100 a month made.

1970 was a lot bigger production year to 1969 where only 10,118 were made or 1971 where there were 10,234 made

the Aichele book "Porsche 911 Forever Young says that in 1970 there were 9280 coupes built and 4749 targas (14029) - but I am not sure if this included Karmann models or not ( I think it does)
it says the numbers for 1969 were 9187 coupes and 3493 targas ( 12,600) and for 1971 5817 and 4789 (10,606) still a lot more than 300 a month

it is also unclear if the Aichele is talking about CALENDAR years or model years I suspect calendar years as the 1969 year is higher than Morgans and the 1970 year lower

so closer to 250 a day across both sites

****Huh?

I thought I read that the early 911 daily production goal was about 36 cars....

[Bobs 67S]

Back of an envelope calculation:

Yearly production at 14,266
11.5 months = 1241 per month
20 production days per month (weekends off) = 62 per day
for two production sites that could be : 31 cars per day from each assembly line.

(how many shifts were they working?)
(didn't factor in other Holidays)


Target of 36 cars per day sounds about right.

Good catch Mike Typo now fixed Bob did the calc anyway
