Tesla delivered 50,580 EVs in 2015 across all its markets; its Q4 deliveries consisted of 17,192 Model S vehicles and 208 Model X vehicles. (507 Model X vehicles were produced during Q4 with the remainder to be delivered in early Q1.)
Q4 Model S deliveries were approximately 48% more than the company’s prior quarterly record and approximately 75% more than Q4 2014. Tesla said that its Model X deliveries are in line with the very early stages of production ramp. The daily production rate in the last week of 2015 tracked to production of 238 Model X vehicles per week.
Tesla said there may be small changes to this delivery count (usually well under 1%), as Tesla only counts a delivery if it is transferred to the end customer and all paperwork is correct.
