Tesla is finally making a profit. For the first time, the California-based electric carmaker has posted two quarterly profits in a row.

Those profits were driven by pricey cars — higher-priced variants of Tesla's new Model 3, which sell for $50,000 and up.

But instead of doubling down on the strategy that proved profitable, Tesla is laying off thousands of people to slash costs, reducing production of the Model S and Model X and building a new factory in Shanghai. It's all part of an aggressive push to make cars for the mass market that sell for $35,000.

That's because Tesla CEO Elon Musk doesn't want to just sell expensive cars to the world's elite. He never did.

Musk called it his "Secret Master Plan." The "secret" part was a joke — he talked about it all the time. But the "master plan" bit was very serious.

Step 1: Make a high-performance, extremely expensive electric sports car, something people would be willing to plunk down $100,000 for: the Roadster.

Step 2: Use that money to make a cheaper vehicle — and use that money to make an even cheaperone. Eventually, Musk said, the company would mass-produce a truly affordable electric vehicle.

The underlying goal was nothing short of saving the world. A few rich people driving electric sports cars wouldn't shift the needle on climate change. But an electric car for everyone? That could do it.

Musk has been remarkably consistent on this vision. In 2006, he wrote that the company's "overarching purpose ... is to help expedite the move from a mine-and-burn hydrocarbon economy towards a solar electric economy."

At the end of 2018, he told 60 Minutes, "The whole point of Tesla is to accelerate the advent of electric vehicles and sustainable transport and trying to help the environment. We think it's the most serious problem that humanity faces."

Mass-market cars, like Tesla's Model 3, were key to this vision.But scaling up production is notoriously difficult.The last year and a half has been painful for Tesla, as the company coped with production challenges and delivery woes.

Tesla has massively increased production of the Model 3: The company sold nearly 140,000 Model 3s last year. But it still hasn't managed to offer the car at its touted price of $35,000.

It's still trying, despite the challenges: "The road ahead is very difficult," Musk told employees on Jan. 18.

In the meantime, Tesla is competing successfully with conventional luxury brands.

Brian Moody, the executive editor for Autotrader, says Tesla should walk away from the master plan and just admit that it's a premium carmaker.

"We can just be honest and call them luxury cars," he says. "And I don't think there's anything wrong with that. ... They've created something great that people love. Good. Congratulations. You should enjoy your success and keep doing more of that."

It'sonly Tesla's "philosophy" that is pushing the company in a different direction, Moody says.

Still, it's not like Musk's master plan is entirely at odds with business interests.

"At the end of the day, Tesla is a for-profit company — it's not a nonprofit," says Jessica Caldwell, the executive director of industry analysis at Edmunds. "It's going to have to make money."

"Elon Musk and Tesla having this grander vision for humanity and civilization is certainly different than the way that other auto companies run their business day to day," she says. But building a car for the masses also opens up new markets that could help the bottom line.

"Tesla's up against the wall," she says. "It feels like there are some real business pressures on them."

The company has already blown multiple self-imposed deadlines for the Model 3.Meanwhile, traditional carmakers are investing serious money in bringing new electric cars to market. That, of course, was always part of Musk's plan — but it means new competitive pressure, too.

Investors and analysts are waiting to see whether Tesla can pull off the long-planned transition to high-volume, low-cost vehicles.

And would-be buyers are waiting, too.

Mark Vidaurri of San Antonio test-drove a Model 3 a few weeks ago. He loved it — but was let down by the price tag. At well above $35,000, it's out of his reach.

"I believe advancements in technology shouldn't be a luxury," he says. "It should be something that is discovered and ... able to distribute across every class of citizen."

He still dreams of a Model 3 in his driveway. Someday — when it's more affordable.
