Electric carmaker Tesla has notched up its biggest quarterly loss to date, sending its shares down more than 5% in after-hours trading.
It made a loss of $619m (£468m) in the three months to 30 September, up from $336m in the previous quarter. It saw a profit of $21.9m a year earlier.
The firm also delayed its production target for its new Model 3 car.
Tesla said it would now be producing 5,000 of the cars a week in early 2018, instead of December.
It added that it had produced just 260 of the Model 3 cars in the third quarter, rather than the 1,500 it had planned to build.
The Model 3, seen as Tesla’s best long-term hope, is priced at about $35,000, about half the price of its high-end Model S car.
Quarterly revenues were $2.98bn, 30% higher than the same period last year.
