Tesla’s German plant will step up output in the second half of the year thanks to stronger-than-expected demand, plant manager André Thierig told news agency DPA. He said production plans for Q3 and Q4 have been revised higher, though without giving exact numbers, and added that the company sees positive signals across its markets.

The optimism contrasts with recent weak sales data. Registrations of new Teslas fell 39% in Germany last month and are down 56% year-to-date. Similar steep drops were seen in France, Belgium, Denmark and Sweden, while Norway was a rare bright spot with double-digit gains. Executives, including Elon Musk, have blamed the slump on Model Y production changes at the Berlin-area plant, which disrupted supply temporarily.
