Tesla (TSLA) released its Q2 deliveries and production numbers on Wednesday, July 2. The deliveries, which closely approximate vehicle sales fell 13.5% year-over-year. The decline was higher than the 13% fall in Q1 and was the worst ever for the company.

Tesla vehicle sales have been under pressure in the U.S., China and Europe in Q2. Forbes reported Thursday that Musk fired Omead Afshar, Tesla's head of operations in North America and Europe. Afshar began at Tesla in 2011 and, during his tenure, reportedly became one of Musk's top lieutenants and most trusted allies.
