Will the 10,000th registration of a Tesla Model S in California be in 2013 or 2014? A little less than half of all of the deliveries of the Tesla Model S's so far went to customers in California. With half of 2013 still ahead of us, about 5,000 (or maybe even 6,000) Tesla Model S's have been delivered already to customers in California (including the deliveries in 2012). But we have to keep in mind that in the second half of 2013 the Tesla Model S's for Europe and Asia have to be manufactured and shipped and delivered as well. So, the deliveries to customers in the US will be less than they were in the first half of 2013. But all will be different if Tesla Motors decide to increase the production capacity (to a weekly production of 800?).
