Tesla expects to reach volume production of Model 3 by September

Munster: Tesla will continue to move higher

Tesla said Wednesday that its Model 3 program is "on track" to start limited volume production in July, with volume production reached by September.

From there, the company will steadily ramp up to produce more than 5,000 vehicles per week by some point in the fourth quarter. By 2018, it should reach production of 10,000 vehicles per week.

The electric vehicle maker said volume deliveries of the Model 3 should begin in the second half of 2017.

The Model 3, which is priced starting at $35,000, is a major step for the company as it will mark Tesla's transition from a small niche manufacturer of high-end electric vehicles to a mass market manufacturer.

Tesla's update on the Model 3 comes as the company reported a wider-than-expected fourth-quarter loss even though its sales were higher than expected.

"Ahead of the Model 3 launch, we are reengineering and expanding our operations as we anticipate the needs of a much larger family of Tesla owners," the company said in a letter to investors.

The company also said it is expanding its mobile repair service to allow it to make vehicle repairs at an owner's home or office, since more than 80 percent of its repairs are so minor they can be done remotely.

Tesla also is expanding its Supercharger network with the goal of doubling its North American Supercharger locations this year.

The company has already built Model 3 prototypes and initial crash test results have been "positive."
