In its Q2 2014 Shareholder Letter, the company said it had delivered 7,759 Model S electric luxury cars during the second quarter of the year, up 17% on the first quarter.

However, despite increased battery cell production from partner Panasonic in Japan, waiting times increased during the first half of the year as deliveries began in new markets, including the United Kingdom and China.

To futureproof itself, the carmaker is currently upgrading its factory in Fremont, California to increase production from 800 units per week, expecting that it will manufacture over 1,000 per week in the fourth quarter.

Although this will reduce annual output by 2,000 units, Tesla expects to have delivered cars to 35,000 Model S customers by the end of the year, up 56% on 2013’s 22,500 deliveries.

During 2015, with sales underway in yet more markets and the Model X SUV introduced, Tesla expects Fremont to have manufactured 100,000 units during 2015 – almost a three-fold increase on this year, or an average of around 1,920 cars per week.

Design-confirming Alpha prototypes of the Model X are imminent, with Beta prototypes to follow, and company is due to announce the location of its battery Gigafactory, with Panasonic, in the next few weeks.
