The factory in Fremont, California, had previously manufactured 800 Model S cars per week, but with sales now under way across most of Europe and China and extra markets to follow, CEO and co-founder Elon Musk said the company was looking to cut its four-month lead times.

When production restarts on the 4th August, Fremont’s more efficient production line will have the capacity needed to build 1,000 cars per week, a figure Tesla expects to reach by the end of the year. The line will also be ready for the launch of the Model X early in 2015, which is likely to significantly increase the manufacturer’s global sales.

Tesla delivered the first Model S electric executive cars to UK customers in June, in right hand drive, and the Model X will be delivered here at the end of 2015. Based on the same platform as the Model S, it features fully electric four-wheel drive and seven seats.

The compact executive Model III is scheduled to begin production in 2017, priced at around £25,000, Musk confirmed last week, and the carmaker is already considering additional factories in Europe and possibly China to meet expected demand.
