April 20 (Reuters) - Elon Musk is counting on full-self driving and other new technologies and vehicles at Tesla Inc to provide the "wow factor" that will continue to drive the electric carmaker's value far beyond its automotive rivals.

Some analysts and investors worry that Tesla's industry-leading market valuation is threatened by factors including price cuts that have undermined its margins, delays in rolling out new models and revisions to its full self-driving (FSD) software.

"Tesla faces an increasingly uphill battle to secure its competitive position, which makes its current valuation look even more unrealistic," said David Trainer, CEO of investment research firm New Constructs. "The Tesla bull case has centered around the company's growth goals, which it is failing to meet."

Tesla's stock is trading at about 43 times expected earnings, down from astronomical levels above 200 times in 2021, according to Refinitiv data. Even after that drop, the company's valuation remains several times higher than the multiples of legacy carmakers, with Ford Motor Co trading at about 8 times expected earnings and General Motors Co trading at under 6.

Tesla on Wednesday doubled down on the price war it started at the end of last year, as Musk said the company would prioritize sales growth ahead of profit. In the first quarter, Tesla posted its lowest quarterly gross profit margin in two years.

"The market wants to see that Tesla management has a tangible plan to boost automotive gross margins and companywide operating profit margins over the coming quarters and in the next year or so," said Morningstar analyst Seth Goldstein. "I also think the market wants to see a growth plan that does not involve continuous price cuts."

Musk brushed aside those fears on Wednesday, saying the company this year would likely launch FSD, which costs $15,000, and which will be a big profit generator. That is almost a third of the roughly $47,000 current starting price of the base Model Y in the United States.

Musk has missed his previous targets to achieve self-driving capability, dating back years.

"We're the only ones making cars that technically, we could sell for zero profit for now and then yield actually tremendous economics in the future through autonomy," he told analysts on a conference call on Wednesday. "I'm not sure how many people will appreciate the profundity of what I've just said, but it is extremely significant."

GOLD STANDARD

Skeptics remain over how soon Tesla will launch FSD.

"This is a bit like the boy who cried wolf, except in our story the wolf would be a good thing that never seems to come," said Bryant Walker Smith, a law professor at the University of South Carolina who closely follows the development of advanced vehicle technologies.

"It's not clear to me how that timetable in any way is consistent with the evidence we have seen," he added, describing the current version of FSD as "highly imperfect."

Other key products expected from Tesla include the Cybertruck pickup later this year, as well as a lower-cost car that is expected in late 2024 or early 2025. Longer-term, Tesla believes robots could be a bigger profit generator than EVs.

Evangelos Simoudis, video bokep a technology adviser, author and investor, believes Tesla may have an even bigger opportunity" in energy generation and storage with its solar panels and Powerwall battery systems.

Not only is Tesla viewed as the gold standard in the auto sector, but many see it as more of a tech stock. Canaccord Genuity analyst George Gianarikas compared Tesla favorably to such tech stocks as Alphabet Inc, Meta Platforms Inc , Nvidia Corp, Apple Inc, Microsoft Corp and Amazon.com Inc.

"If you look at the growth rates for Tesla versus those companies, Tesla is growing its revenue significantly more than their EBITDA, and so we feel like it's incredibly compelling relative to those companies because you're paying not only a lower PE but also you get better growth," said Gianarikas.

Ultimately, some industry observers feel investors are betting more on the man than the models.

"You're not investing in Tesla. You're investing in Elon Musk," said Kim Forrest, chief investment officer of Bokeh Capital Partners.

For true believers in Musk and Tesla, their faith will remain intact even if FSD is not launched this year, said Will Rhind, CEO of GraniteShares, an asset manager in New York that offers exchange-traded funds (ETFs) allowing investors to bet either long or short on Tesla stock.

"Potentially it never happens that the retail investor gives up the ghost," he said.
