Tesla has reported another hefty drop in auto sales extending a difficult period amid intensifying electric vehicle competition and backlash over CEO Elon Musk's political activities. On Wednesday, the electric vehicle (EV) maker reported 384,122 deliveries in the second quarter, representing a 13.5 percent decline from this time a year ago. Its earnings report will be released after the market close. Sales were roughly in line with analyst expectations. The global sales figures reflect the more contested nature of the EV market, which Tesla once dominated, but which now also features BYD and other low-cost Chinese companies, as well as legacy Western carmakers like General Motors, Toyota and Volkswagen.
