Tesla is headed for another year of shrinking sales after it posted a second straight drop in quarterly deliveries, dragged down by CEO Elon Musk's right-wing political stances and an aging vehicle line-up that has turned off some buyers.

Tesla, the electric vehicle maker led by Elon Musk, saw global sales drop 13.5%, marking the second consecutive quarter with double-digit declines.
