Since the new Grohmann equipment is coming early Q4 in the Gigafactory:
Grohmann Engineering will help module production become three times faster, and three times cheaper, according to Viecha. Their new system will be sent to the Gigafactory by the end of Q3 or beginning of Q4. The Grohmann machine will be in Zones 1, 2, 3, and Tesla will be receiving three machines. The process was designed to alleviate the previous bottleneck in module production which delayed Model 3 production significantly.
So 5,500 x 12 weeks (lose a week for Holidays in December..) = 66,000.
