Electric vehicles (EVs) often get a bad rap for range loss in cold climates, but a new study of Teslas shows that cooler regions may actually be better for an EV’s battery over the long term.
On Monday, Recurrent Auto shared results from a study showing that Tesla vehicles owned and operated in cold climates had better average range scores than those in hot climates (via electrek). The study looked at over 12,500 Tesla vehicles in the U.S., using data Recurrent has access to through its software.
While the study found this to be true amongst multiple Tesla models and model years, the results were most prominent in the Model Y. In particular, Model Y units with the 2020 model year averaged range scores of 95 in colder climates and 92 in warmer climates, as can be seen in the following infographic.

Researchers gave the Teslas range scores to capture how much of a given EV’s range was still expected at the time of the study. A Tesla vehicle with a range score of 90, for example, would still have 90 percent of its initial range. Additionally, the study was conducted using the U.S. Department of Energy’s “hot,” “cold,” and “marine” climate designations.
As for why the study only included Teslas, Recurrent notes that they are the most common EVs available, garnering the most data. They also cite Tesla’s battery thermal management system, which they say offers great protection against environmental damage to the battery’s long-term health.
According to Recurrent, heat from the environment contributes additional energy to an EV battery’s electrochemical reactions, accelerating unwanted chemical reactions that cause the battery to age. It also says 86 degrees Fahrenheit (30 degrees Celsius) is the generally accepted threshold for accelerated battery degradation.
While range loss may occur in colder climates due to energy consumption from keeping the cabin warm, Recurrent says this is short-term. Because it does not have the same electrochemical effect as heat on an EV battery, the battery’s range will return once it becomes warmer.
Recurrent provides additional details on heat and long-term battery degradation here, and about the short-term effects of environmental heat here.
Despite the results, there are a handful of things Tesla owners in warmer climates can do to protect the longevity of their batteries. For one, parking in the shade or in a garage can help prevent the battery from heating up as much. When you need to park in the sun, Recurrent recommends charging only to about halfway, as the battery is a little more stable at that level.
Whether buying new or used, buyers may also want to consider newer lithium iron phosphate (LFP) batteries, as they tend to be more resilient in hot climates. Anyone purchasing a used EV should consider how that vehicle was stored and used during previous ownership.
Lastly, the researchers highly recommend owning a car with an active thermal management system, which owners should leave plugged in when not in use. According to Recurrent, this lets the vehicle initiate battery cooling at lower temperatures than when they’re unplugged.

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 prepares to expand Giga Texas with new Optimus production plant
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today.
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.
Tesla Optimus gets its latest job, and it’s not in the company’s factories
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!
Here are some… pic.twitter.com/7ig5DohfOt

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.
Tesla revealed its first customer for the all-electric Semi truck after it launches next year. Who it truly is should not be a surprise.
The Semi is going to finally start deliveries to new companies outside of Tesla’s pilot program starting in 2026. The company has been building a dedicated production facility in Reno, Nevada, that has finally taken shape, but Tesla was evidently not finished with the Semi’s development.
Last week at the Annual Shareholder Meeting, Tesla said it had implemented some new designs into the Semi, helping with efficiency, updating its design, and making it a more suitable vehicle for hauling loads, as the changes also helped increase payload.
Tesla has obtained a lengthy list of companies that have committed to implementing the Semi in their own fleets, hoping to bring their logistics lineups up to date with electric powertrains and autonomous technologies.
While it is already operating a pilot program with PepsiCo. and Frito-Lay, Tesla will expand to other businesses, primarily using it internally after its launch.
Head of the Semi program at Tesla, Dan Priestley, said the company would be the first user of the vehicle after its launch next year. It has been using it to a certain extent, but the company has not been able to completely abandon gas haulers.
Instead, it will implement the Semi into its fleet for more sustainable vehicle logistics starting next year:
Tesla will be the first customer as we electrify our supply chain. This includes Texas operations.

Tesla has already received orders for the Semi from a variety of large companies, including Walmart, Sysco, Anheuser-Busch, UPS, DHL, J.B. Hunt, among others.
Many analysts see the Tesla Semi as a major contributor to future growth and increasing value within the company, especially from a Wall Street perspective. Some firms say the Semi is one of several near and medium-term contributors to the company increasing its market cap.
Cantor Fitzgerald is just one of those firms, as last week it explicitly listed the Semi as a catalyst.
Analyst Andres Sheppard said, “Overall, we remain bullish on TSLA over the medium to long term. We continue to see meaningful future upside from Energy Storage & Deployment, FSD, Robotaxis/Cybercab, Semis, and Optimus Bots.”
