Tesla’s European sales almost halved last month, undermining hopes that the revamped Model Y will revive the company’s fortunes in the region. The electric-vehicle maker sold 6,964 cars in Europe in October, down from 13,519 in the same month last year, according to data released Tuesday by local trade body ACEA. Year to date Tesla’s sales have fallen 30% in the region compared to the same period of 2024, despite a broader rebound in EV sales.
