If I remember correctly, a Porsche car in Zuffenhausen is about 2 days in the assembly line. However, Porsche has one of the lowest production depth in car industry. It is about 20% only. That is, 80% of the car built is outsourced and complete elements are delivered by suppliers.



That's correct - if I recall correctly, Porsche needs close to 30 hrs to build the car (for comparison: VW needs some 50 hrs to build a VW Passat due to higher production depth + maybe less productivity).

SL Boy's numbers should be quite accurate: when I visited the factory at the end of March, the target tact time was appr. 5 minutes whereas the actually achieved tact time was 4:40 min. (i.e. completed cars came off the assembly belt every 4:40 minutes) - I had the impression that there was not much free capacity left (unless they would invent a third shift).
