Auto maker Tesla Motors Inc has announced that the company has delivered a record 10,030 cars during the first quarter.

According to the car maker, this is a 55 percent rise as compared to the number of deliveries made in the first quarter of 2014.

The number of new car deliveries will be published by the company within three days of quarter end. According to the company, the three days time has been decided as several inaccurate sources of information are often used by others in publishing the final figures of vehicle deliveries.

Tesla is expecting to deliver nearly 55,000 cars worldwide this year. This is an increase of approximately 74 percent.

The stock of the company has been battered in 2015 by the investors who are concerned about its failure to hit the sales targets in China as well as the departures in 2014 of two top Tesla executives in that nation.

Elon Musk, chief executive official of electric car maker Tesla Motors, took to the micro-blogging site Twitter earlier in the week to post several optimistic statements about the sagging operations of the company in China.

Up to close of USD 191 on Thursday, the stock had tumbled 14.1 percent in 2015.

Tesla Motors is going to offer upgrades on its vehicle models, such as hands-free steering on its Model S sedan in three months, roughly a year ahead of other automobile companies.
