"Electric car maker Tesla has reported a fourth-quarter loss of $108m (£71m), compared to a loss of just $16m during the same period a year ago
Nonetheless, in a statement accompanying earnings Mr Musk said "we remain convinced of the vast potential of this market".
Tesla shares plunged 3% in after hours trading.
Furthermore, Tesla said production delays led to fewer shipments of cars than had been expected in the fourth-quarter.
The company said it built 11,627 vehicles but only shipped 9,834 cars during the period, blaming the miss on production delays and shipping problems.
"While we were able to recover the lost production by end of the quarter, delivering those cars was physically impossible due to a combination of customers being on vacation, severe winter weather and shipping problems (with actual ships)," the company said in its earnings.
Tesla said it planned to deliver 55,000 of its Model S and X vehicles in 2015 - 70% more than it delivered in 2014."

Chinese negotiators sought at a climate conference in Lima, Peru, to delete provisions in a draft text that would have paved the way for other countries and non-governmental organizations to submit questions about its carbon reduction plans, according to environmental groups that are official observers to the talks. The pledges will be included in a global deal to be sealed next year and that starts in 2020.
The United States and China last month jointly announced efforts they plan to make under the new climate deal.
"The spirit of constructive cooperation of the US-China agreement seems to have come to a full stop," Liz Gallagher, senior adviser to the policy analyst group E3G, said on Saturday in an interview in Lima, where two weeks of UN climate talks began last Monday.
Chinese negotiator Su Wei did not immediately reply to an e-mail seeking comment.
"This is exactly the kind of risk that we face when hard lines are taken by parties," Tasneem Essop, a spokeswoman on climate policy for the environmental group WWF International, said. "It's early days…so we do hope that arties will soften their lines."
Essop said her remarks referred to all nations. She also criticised what she called a "slash-and-burn" exercise by the United States, European Union, Australia, Canada and New Zealand to remove any reference to a review of the commitments they had made to cut emissions before 2020."
