The Tesla Model Y and Model 3 are still the best-selling electric vehicles in the world in September, a remarkable achievement given that both EVs are premium models that typically command higher prices than their competitors.

The two vehicles’ feat was highlighted recently by CEO Elon Musk in a post on X.

Still best-selling

As observed by tech watcher @XFreeze, the Model Y and Model 3 were the world’s #1 and #2 best-selling electric vehicles in the world in September 2025. Interestingly enough, the list includes both battery electric vehicles and plug-in hybrid electric cars. 

During the month, Tesla was able to sell 140,904 Model Y crossovers and 67,374 Model 3 sedans across the globe. This is quite impressive considering that the Model Y and Model 3 have been around for several years now, and they are still premium-priced.

Staying power

The Model Y and Model 3’s stellar staying power may be due to a variety of factors, including the vehicles’ bang-for-the-buck nature. The Model 3, for example, is quite a bit closer to the price of a Toyota Camry or Honda Civic, but its amenities are closer to those of the BMW 3 Series. The same is true for the Model Y.

Despite their relatively mainstream price, the Model 3 and Model Y offer a ton of tech features that are only available in Teslas. These include Full Self-Driving, which is steadily becoming a huge selling point in territories where it is available, and the company’s vast suite of tech-centric convenience features. The fact that the Model 3 and Model Y are among the safest vehicles in their respective classes doesn’t hurt either. 

Tesla has lost its Model Y Program Manager, he announced on LinkedIn, marking the second major departure from the company today.

Emmanuel Lamacchia has been in the role for 4 years and 7 months, responsible for the rollout of the all-electric crossover in several markets.

The Model Y became the best-selling vehicle in the world for two years under Lamacchia’s watch, making this a huge loss for the company. However, it seems the decision was made under Lamacchia’s own initiative.

He confirmed his decision on LinkedIn:

“After 8 incredible years, I’m moving on from Tesla.

What a journey it’s been… from leading NPI for Model 3 and Model Y variants to becoming the Vehicle Program Manager for Model Y, the best-selling car in the world!

Leading the All-New Model Y launch was the highlight: converting all 4 factories across 3 continents in just 2 weeks. Something that had never been done before in the auto industry.

To the teams who made this possible: you should be incredibly proud. This achievement belongs to you: the engineers, designers, buyers, and associates in Fremont, Shanghai, Berlin, and Austin who turned an impossible timeline into reality.

Grateful to the leaders who trusted me with programs that stretched my capabilities and to the cross-functional partners who showed me that great solutions come from collaboration, not hierarchy.

Tesla taught me how to move fast without breaking things and how to scale from prototypes to millions of units.

Excited for what’s next. More to share soon.”

It marks the second major program loss for Tesla today, as it also bid farewell to Cybertruck and Model 3 Program Manager Siddhant Awasthi, who said he left voluntarily in “one of the hardest decisions of his life.”

Lamacchia was at Tesla for just a shade under eight years, and previously worked for Rolls-Royce for roughly the same amount of time.

After the loss of both Lamacchia and Awasthi today, Tesla has lost a handful of key executives in 2025, including:

• David Imai, Director of Design
• David Lau, VP of Software Engineering
• Mark Westfall, Head of Mechanical Engineering
• Prashant Menon, Regional Director in India
• Vineet Mehta, Head of Battery Architecture
• Omead Afshar, VP/Head of Sales and Manufacturing in North America
• Milan Kovac, Head of Optimus Team
• Jenna Ferrua, Director of HR
• Troy Jones, VP of Sales, Service, and Delivery
• Pete Bannon, VP of Hardware Engineering
• Piero Landolfi, Director of Service

Tesla is preparing to expand Gigafactory Texas once again with a brand new facility that will house the eventual manufacturing efforts for Optimus, its humanoid robot.

It is already building some units on a Pilot line at the Fremont Factory in Northern California, but Tesla is planning to build the vast majority of its Optimus project at Gigafactory Texas.

It will build one million units per year in Fremont, but CEO Elon Musk said the company would build 10 million units every year in Texas at a new building at Giga Texas.

Musk said:

“I think there could be tens of billions of Optimus robots out there. Um, now obviously it’s very important we pay close attention to safety here. Then a 10 million unit uh per year production line here the I don’t know where we’re going to put the 100 million unit production line. on Mars. Maybe on Mars, I don’t know.”

Evidently, Tesla is ready to begin thinking about the production efforts of Optimus beyond a theoretical standpoint and is starting to prepare for the construction of the manufacturing plant on Giga Texas property.

Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today:

Giga Texas News!

A brand-new, stand-alone factory is starting construction! This follows the Shareholders meeting & info that a 10-million-per-year @Tesla_Optimus production facility “on the Giga Texas campus” will be built & enter into production in 2027!

Production is still slated for 2027, at least at Gigafactory Texas. As previously mentioned, the company is building some units in Fremont for the time being, at least until subsequent versions of the Optimus project advance.

Tesla has done a great job of advancing Optimus forward, but it also has truly grand expectations for the project.

Musk said it could potentially be the biggest product in the history of the planet, as it will revolutionize the way humans perform tasks, probably eliminating monotonous tasks from everyday life.
