Tesla delivered just over 22,000 vehicles in the second quarter of 2017, of which just over 12,000 were Model S and just over 10,000 were Model X; representing a 53% increase year-on-year. Total vehicle deliveries in the first half of 2017 were approximately 47,100.

According to the premium electrical carmaker, the major factor affecting its Q2 deliveries was a severe production shortfall of 100 kWh battery packs, which are made using new technologies on new production lines. “The technology challenge grows exponentially with energy density. Until early June, production averaged about 40% below demand. Once this was resolved, June orders and deliveries were strong, ranking as one of the best in Tesla history”, said Tesla in a statement.

Production in the second quarter totalled 25,708 vehicles, bringing first half 2017 production to 51,126.
