Tesla sales rebounded massively in the second quarter, after months of steep declines.

U.S. sales growth is unclear, but ACEA data points to a huge surge in Tesla's sales in the European Union.

The automaker's energy storage businesses also witnessed robust growth.

Tesla's global deliveries rebounded sharply in the second quarter, defying Wall Street expectations after two consecutive quarters of sales declines. The automaker's passenger vehicle business has been struggling amid its pivot to AI and robotics, but the latest numbers show its aging lineup still has some legs.

Tesla reported 480,126 deliveries in the second quarter, a nearly 25% year-over-year jump. The vast majority of those sales came from the Model Y and Model 3, which together accounted for 467,762 deliveries during the period. Its other models, including the Cybertruck and the now-discontinued Model S and Model X, made up the remaining 12,364 deliveries, up 19% year-over-year.
