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 CEO Elon Musk sends final warning to Bill Gates over short position
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said.
Tesla CEO Elon Musk sent a final warning to former Microsoft CEO Bill Gates over his short position, which he confirmed he held to Musk directly several years ago.
Gates has been a skeptic of Tesla for some time, but he has also tried to work with Musk on philanthropic opportunities several years ago, which was coincidentally when he admitted to the company’s frontman that he held a short position.
Musk was, in turn, “super mean” to Gates, according to Walter Isaacson’s biography about the Tesla CEO. Gates had put $500 million against Tesla, shorting the stock and hoping to profit from its failure.
Elon Musk explains Bill Gates beef: He ‘placed a massive bet on Tesla dying’
A short position essentially means Gates is betting Tesla shares will go down, which would make him money. However, shares have gone up over six percent this year and increased nearly 150 percent over the past five years.
At the recent Annual Shareholder Meeting, Musk made many claims about Tesla’s future projects and how they could manage to disrupt various industries. He also recently had a massive $1 trillion compensation package approved, which will be awarded in twelve tranches, all of which combine a company valuation goal and an individual goal related to a product.
Musk was able to complete his last approved pay package, but it was not awarded due to a ruling by a Delaware Chancery Court. Nevertheless, his track record of proving growth for Tesla shareholders is excellent, and investors are obviously very encouraged by his capabilities as a CEO, considering 76.6 percent of shareholders voted to approve his new compensation.
After it was revealed that the Gates Foundation dumped 65 percent of its Microsoft position for nearly $9 billion, Musk had one final message for him: drop your Tesla short position soon, or else.
If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon
— Elon Musk (@elonmusk) November 16, 2025
Musk’s rivalry with Gates is mostly founded on the Tesla CEO’s discontent with the former Microsoft frontman’s short position. However, Musk might have a bit of a soft spot for Gates, considering he is giving him a warning of what is potentially to come. If he really wanted to do some damage to Gates, he would not give him any heads-up at all.

Tesla rolls out most aggressive Model Y lease deal in the US yet
With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Tesla has rolled out what could very well be its most aggressive promotion for Model Y leases in the United States yet. With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Zero downpayment leases
The new Model Y lease promotion was initially reported on X, with industry watcher Sawyer Merritt stating that while the vehicles’ monthly payments are still similar to before, the cars can now be ordered with a $0 downpayment.
Tesla community members noted that this promotion would cut the full payment cost of Model Y leases by several thousand dollars, though prices were still a bit better when the $7,500 federal tax credit was still in effect. Despite this, a $0 downpayment would likely be appreciated by customers, as it lowers the entry point to the Tesla ecosystem by a notable margin.
Premium freebies included
Apart from a $0 downpayment, customers of Model Y leases are also provided one free upgrade for their vehicles. These upgrades could be premium paint, such as Pearl White Multi-Coat, Deep Blue Metallic, Diamond Black, Quicksilver or Ultra Red, or 20″ Helix 2.0 Wheels. Customers could also opt for a White Interior or a Tow Hitch free of charge.
A look at Tesla’s Model Y order page shows that the promotion is available for all the Model Y Premium Rear-Wheel Drive and the Model Y Premium All-Wheel Drive. The Model Y Standard and the Model Y Performance are not eligible for the $0 downpayment or free premium upgrade promotion as of writing.

Tesla is looking to phase out China-made parts at US factories: report
Tesla has reportedly swapped out several China-made components already, aiming to complete the transition within the next two years.
Tesla has reportedly started directing its suppliers to eliminate China-made components from vehicles built in the United States. This would make Tesla’s US-produced vehicles even more American-made.
The update was initially reported by The Wall Street Journal.
Accelerating North American sourcing
As per the WSJ report, the shift reportedly came amidst escalating tariff uncertainties between Washington and Beijing. Citing people reportedly familiar with the matter, the publication claimed that Tesla has already swapped out several China-made components, aiming to complete the transition within the next two years. The publication also claimed that Tesla has been reducing its reliance on China-based suppliers since the pandemic disrupted supply chains.
The company has quietly increased North American sourcing over the past two years as tariff concerns have intensified. If accurate, Tesla would likely end up with vehicles that are even more locally sourced than they are today. It would remain to be seen, however, if a change in suppliers for its US-made vehicles would result in price adjustments for cars like the Model 3 and Model Y.
Industry-wide reassessments
Tesla is not alone in reevaluating its dependence on China. Auto executives across the automotive industry have been in rapid-response mode amid shifting trade policies, chip supply anxiety, and concerns over rare-earth materials. Fluctuating tariffs between the United States and China during President Donald Trump’s current term have made pricing strategies quite unpredictable as well, as noted in a Reuters report.
General Motors this week issued a similar directive to thousands of suppliers, instructing them to remove China-origin components from their supply chains. The same is true for Stellantis, which also announced earlier this year that it was implementing several strategies to avoid tariffs that were placed by the Trump administration.
