Shares of Tesla (TSLA) - Get Report surged in after-hours trading on Wednesday as the electric automaker reported second quarter earnings results that topped consensus estimates.

Shares continued to rise on Thursday, climbing over 5% higher during morning trading. 

The quarter also left investors and fans of Tesla more at ease with underlying concerns they had coming into the results announcement.

By far the most talked about aspect of Tesla's second quarter was centered around its recently released, highly-anticipated Model 3, the company's more affordable electric vehicle aimed at bringing its technology to the masses.

Tesla CEO Elon Musk had some strong words regarding the delivery of the model, which was scrutinized by analysts questioning how the company would keep pace with orders.

"What people should absolutely have zero concern about, and I mean 0, is that Tesla will achieve a 10,000 unit production week by the end of next year. [...] I think people should really not have any concerns that we won't reach that outcome from a production rate," Musk said on Tesla's conference call., a website covering all things Tesla, said that statement from Musk was "surprisingly strong" seeing as how the CEO usually offers up phrases like "my best guess" or "I might be wrong."

"But in this case, Musk showed no doubt, and the market heard him," Electrek noted.

Musk said Tesla's current goal is to ramp up production to 20,000 units a month by December, from 1,500 units a month in September.

Another concern bloggers and investors had coming into the results was whether the Model 3's popularity would cannibalize sales of Tesla's other models like the S or X.

But, Musk again eased concerns there saying that orders for both the Model S and X have been up. In July, orders were said to be 15% higher than normal for the second quarter. 

Tesla said it expects deliveries of Model S and Model X to increase during the second half of 2017. "This is the best I've ever felt about Tesla to be frank," Musk said. 

Electrek added that it doesn't expect Tesla to start delivery of the Model 3 outside of the U.S. until the second half of 2018, and even later for right-hand drive markets, to the benefit of other models.

"It's like if you have a restaurant and you're serving hamburgers and there's like a 1 hour wait for a hamburger, do you really want to encourage more people to come order hamburgers? That doesn't make sense," Musk said.
