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.

The same report shows that Musk's Tesla ran away with the top spot of the best-selling car brands in June, owning a whopping 30.7% market share (5,646) in the country. The Tesla Model Y was the most popular model, reaching a mark of 5,004 units, which amounts to a total of 27.2% share of all EVs sold throughout the month of June.

Norway’s near-total shift to electric vehicle sales signals a transformative moment for the global automotive industry, with major implications for combustion engines.

The plunge in sales reflect the gains for Chinese EVs, boosted by the troubles at Tesla and the dislike of Musk among those unhappy about his support for conservative causes.
