Tesla posted record deliveries of 97,000 vehicles in Q3'19, marking a sequential increase of about 1,800 units, although they came in below Street expectations. The Model 3 saw sales rise by about 2k sequentially to 79,600 units, premium vehicles continued to under perform, with deliveries dropping slightly to 17,400 units. This puts the company's year-to-date deliveries at ~255k. For perspective, Tesla previously guided 360k to 400k units for 2019, indicating that deliveries over Q4 would need to grow 8% sequentially to meet the lower-end of the annual target. Below we take a look at some of the trends that likely drove deliveries and how it could impact Tesla's Q3 earnings, which are likely to be published by the end of this month.
