Tesla Motors Inc. Chief Executive Elon Musk told an auto industry gathering the Silicon Valley auto maker will need until 2020 to be profitable on a basis that includes charges and executive compensation.

Mr. Musk, making a rare visit to Detroit during the city's annual auto show, said Tesla's Model 3 will need to be in full production mode by the end of the decade to meet the profit goal. The Model 3 is planned as a cheaper and less capable electric car slotted under the Model S sedan and forthcoming Model X SUV in Tesla's lineup.

Tesla's shares were down 7.1% in after-hours trading to $189.70.

The Model 3 is slated for 2017, the same year General Motors Co. aims to launch its Chevrolet Bolt. Both vehicles are designed to travel 200 miles on a single charge, and be closer to the $30,000 through $40,000 range. The Model S often sells above $100,000.

The executive, as expected, urged other auto companies to speed the introductions of electric vehicles. Tesla, currently with volumes around 35,000, should sell "a few million cars" by 2025.

"The need for sustainable transport is incredibly high," he said. "Even in the face of massively declining oil prices I think it only becomes more urgent that the industry advance its development of electric vehicles. It's really just a question of when it goes fully electric, and if it goes sooner that will be good for the world."

To date, Mr. Musk has sold cars directly to consumers, avoiding the franchising arrangement that nearly all auto makers use. He told the Automotive News World Congress he would consider dealers at some point, but he won't work with the dealers who "have been jerks."

He will go to Texas, meanwhile, to lobby for the ability to make direct sales. That trip is scheduled for Wednesday.

Mr. Musk earlier Tuesday told The Wall Street Journal sales of its electric vehicles in China declined significantly in the last quarter of 2014 largely due to "misperceptions" among Chinese consumers about charging.

Sales in China, he said "started off being fairly strong...but in the fourth quarter of last year China was not a significant contributor to our sales."

He said Tesla has to correct a misperception that a Tesla is to charge."

He also said the company is working on a list of electric car brands in China that qualify for special government support and subsidies. He declined to comment on how talks with the issue was going, saying they were "sensitive" and that he is "hopeful."

The charging issue was one reason why he replaced Veronica Wu with Tom Zhu as head of China.

"I put the guy that was in charge of supercharger rollout in China in charge of China overall because the question of charging and the perception of charging and making it easy and convenient is our Number One problem," he said, addressing confusion related to why he made a change in Chinese leadership. "The guy with the best expertise in charging needs to be running China for us."
