Tesla registrations in Sweden surged in September, with the Model Y climbing back to the top spot among fully electric vehicles in the country. The rebound marks a sharp turnaround for the electric vehicle maker, with new Model Y figures showing an impressive 492% increase compared to August.

Strong rebound after difficult year

The Model Y had previously slipped to fourth place in Sweden’s rankings, and even with incentives such as zero-interest financing, momentum had been challenged throughout much of the year. That is, at least, until now, with September’s results suggesting a notable recovery for the best-selling Model Y.

Data from Car.info indicates that the Model Y has become Sweden’s most newly registered car in September. Compared to August’s figures, September’s Model Y registrations have seen a stunning 492% rise. It should be noted, however, that year-over-year registrations are still down in the country, as noted in a CarUp report.

European production sees positive trend

Tesla executives have pointed to the company’s broader strength in Europe. Gigafactory Berlin head André Thierig told German outlet dpa that sales have improved enough to prompt revised production targets for the third and fourth quarters. “We currently have very good sales figures and have therefore revised our production plans,” Thierig said, noting that the factory is operating at full capacity.

Apart from the Model Y’s momentum, used Teslas are also starting to see positive trends in Sweden. As per recent reports, electric car dealer Carla, which has grown into Sweden’s second-largest used EV retailer, Tesla resale values jumped nearly 10% between June and August. So notable was the rise in consumer interest in used Teslas that the vehicles ended up helping Carla rebound into profitability.

Elon Musk has shared some context behind xAI’s lawsuit against rival OpenAI. News of the lawsuit emerged recently, with reports stating that Musk’s artificial intelligence startup was accusing OpenAI of systematically stealing trade secrets.

Musk shared his thoughts in a post on social media platform X. 

xAI’s lawsuit

As noted in a Reuters report, xAI’s lawsuit alleged that OpenAI poached xAI engineers, pressured them to share confidential information, and gained access to the company’s code, business plans, and data center details.

“OpenAI is targeting those individuals with knowledge of xAI’s key technologies and business plans—including xAI’s source code and its operational advantages in launching data centers—then inducing those employees to breach their confidentiality and other obligations to xAI through unlawful means.

“By hook or by crook, OpenAI clearly will do anything when threatened by a better innovator, including plundering and misappropriating the technical advancements, source code, and business plans of xAI,” the lawsuit read.

The lawsuit comes on the heels of a legal complaint that xAI filed against Xuechen Li, a former xAI employee who left to work at OpenAI. The engineer was accused of stealing trade secrets. In its most recent filing, xAI also named “early xAI engineer” Jimmy Fraiture and a “senior finance executive” as persons of interest. 

Elon Musk’s comments

In his post on X, Elon Musk stated that xAI had been trying to communicate with OpenAI about the matter. However, the ChatGPT maker reportedly continued its illicit activities. “We sent them many warning letters, but they continued to cheat. Lawsuit was the only option after exhausting all others,” Musk wrote in his post.

OpenAI, for its part, claimed that xAI’s new lawsuit was just the latest in Elon Musk’s efforts to harass the company. “This new lawsuit is the latest chapter in Mr Musk’s ongoing harassment. We have no tolerance for any breaches of confidentiality, nor any interest in trade secrets from other labs,” an OpenAI spokesperson stated.

Elon Musk is one of the co-founders of OpenAI, and he also served as a key investor in the artificial intelligence startup when it was still operating purely as a nonprofit. Musk later departed the company, however, and he has since taken a very public stance against OpenAI’s shift to a for-profit entity, as well as the activities of its CEO, Sam Altman. 

Tesla has gotten its first-ever Supercharger highway sign in the U.S. state of Arizona, bringing a big change to the appearance of what usually shows drivers where gas, lodging, and food options are.

Although Tesla has the ability to flex its muscles with its EV prowess and its charging presence in the United States, one thing it has never done before is been recognized on a highway sign.

As EVs have gotten more popular in the U.S., owners have relied on in-car navigation to get them to where they need to be.

Highway signs are still useful, though. They can point travelers in the direction of a nice coffee shop, a notable restaurant, or to a lodging option that might not appear on the in-car navigation.

I like to use them to point me in the direction of the nearest Waffle Shop when I’m on the road.

But for the first time, a Tesla Supercharger is advertised on one of these highway signs:

The contrast to the first-ever Tesla Supercharging highway sign is placed directly above the company’s iconic logo: it is the source of energy for what CEO Elon Musk has long sought to replace, gasoline-powered vehicles.

Perhaps a minor addition to a much broader change in the U.S. automotive sector, it serves as a reminder of how far the company has come in the past few years. Thinking back to just before the COVID-19 pandemic hit, Tesla was not doing anything close to what it is now.

It was delivering just over 100,000 vehicles in a quarter. It was not building the Model Y, and it was mostly reliant on its mass-market Model 3 for the vast majority of its volume, about 90 percent in Q4 2019.

Now, the landscape is changing, and it is changing quickly. Since many North American EV makers have access to the Supercharging infrastructure Tesla has built over the past several years, the advertisement of the location is advantageous for many.
