[email protected]!! I had a factory tour scheduled for this Monday (4/1) for several weeks. Just got a call from someone at Tesla that they are not doing any Factory Tours for the first week of April now. He said they are moving machinery around and it would be dangerous to be there so they won't be doing any tours that week. Already booked flights from VA to San Fran just for this tour, already booked nonrefundable hotel in SF, too. So now we're going to do a tour on Sunday (3/31) but it's a day the factory isn't running, so won't be nearly as cool. Really bummed about this...
Bummer!

I want to compare Tesla Model S line to BMW X3 line. X3 are produced at a rate of 445 cars in 16 hours, it takes 30 hours for X3 to be assembled.
This place X3 factory max capacity to ~155,000 cars a year(if plant will work even on weekends).
We know from supplier disclosure that Tesla aim to build 625 cars a week by early autumn. This mean production rate should be 125 cars a day(in 8 hours).
Tesla Model S max production rate could reach ~125,000 cars assuming 4 shifts(each 40 hours) a week(in a week there are 168 hours and 4 shifts common practice for highly automated industries). Sure supply chain should be massively expanded to reach such numbers of Model S produced a year.
Ok, my questions to carrerascott or anyone who will visit the factory soon:
Could you please be soo kind as to ask the guide one of the following questions:
1) How many stations are there on assembly line? OR How long it take for vehicle from entering assembly to finishing the car?
2) May be guide know how long is assembly line(km, meters, miles etc)
3) Recently there was an official announcement that Tesla produce 500 cars a week. Was it done with one shift only?
4) How many people work on assembly line?
Key facts about X3 mentioned on National Geographic MegaFactory video:
445 X3 produced in 16 hours
car spends 128 seconds on stations
more then 3600 welds to build the underbody
over 6500 welds to build body in white
400 robots used to complete body in white
stacker holds over 500 painted bodies until they requested by assembly line
assembly line is a nearly kilometer long(looks like km just in one direction, total after u-turn should be 2km I think)
1800 doors enter subassembly line
80% of the parts delivered on just in time basis
around 1000 ppl work on assembly line
total time it takes to assemble X3 is 30 hours(that mean around 843 stations if we assume 128 seconds per station and 30 hours total time car spends on assembly time).

Overall I want to understand how much more efforts would be needed to create 200,000 a year GenIII assembly line in comparison to what Tesla already done building Model S assembly line...

Sorry for too many letters to read:redface:
