Tesla Battery Range in Sub-Zero and Snowy Conditions
Over the month of January I decided to study the impact sub-zero weather conditions had on the battery range of my Tesla Model S and found it to be diminished by roughly 40%. Range will vary depending on one’s driving habits but the effects of winter on a Tesla Model S and its battery range should roughly mirror the data that I was able to collect.
Collecting Battery Range Data
I recorded my Tesla’s rated range at the beginning of the day and once again at the end of the day. I logged the amount of kWhs consumed during my daily journey, the actual miles driven and the average temperature for that day. All of this was plotted into a data grid so that I can analyze the effects winter conditions would have on my battery range. The results were as follows:

Comparing the Tesla Model S rated range display versus the actual rated miles used during winter weather conditions. Results indicate an increase of 21% to as high as a 57% in energy consumption.
Results
Plotting the % of rated miles used / miles driven against temperature lets us see the correlation between outside temperature and battery range.
Here you can generally see a trend towards improved efficiency as outside temperature increases. There’s one big outlier which turns out to be a day when the roads were covered in snow and ice. Taking out that data point shows a better correlation between temperature and battery range.
Using a trend line we can see that the outlier at the 57% mark should have been closer to 32% had the roads been more clear. Driving through snow and ice conditions affected the range by an extra 25%.
The data point at the 30% mark during 14 degree is a result of me pre-warming the Model S while it was still plugged in. Warming your car up from shore power prior to taking a trip improves your efficiency.
Summary
Using the data above and a calculated trend line I came up with the table below. This table is showing the actual maximum range I’d expect to get out of a 85kW battery pack which has a rated range of 265 miles:
This analysis is based on data I collected on my car over the course of one month and during a variety of winter conditions. I found it really eye opening to see the rated range of my Model S go from 265 to a real world average of 143 miles during the winter (90% charge, 40% range degradation). For the 60kW model this would be 112 miles.
Fortunately Tesla appears to be placing Superchargers closer together which will help alleviate any issue with running out of range because of winter weather conditions.
How do you best prepare for winter driving in your Tesla Model S?
- Expect to use (on average) 40% more power during the winter.
- Expect to lose about 10 miles of real range for every 10 degree drop.
- If the roads aren’t dry expect to lose up to 25% more range.
- Plan your charging and driving accordingly — don’t cut it close.
I hope this information has helped you understand the effects of winter on the Tesla Model S. If you have your own data, observations or questions to share, we’d love to hear them so leave us a note at the bottom of the page.

Why Tesla’s Q4 performance could shock many after incredible Q3
There is still some residual impact to be felt as we enter Q4, and there is a potential shock coming to many investors as it could be stronger than what many think:

Tesla reported vehicle deliveries and energy deployments for the third quarter of 2025 today, blowing analyst estimations from Wall Street firms completely out of the water with its strongest three-month performance in company history.
The strong performance, which resulted in nearly half a million vehicle deliveries in the quarter, was largely driven by the momentum of the EV tax credit, which expired at the end of September, marking the end of the $7,500 discount that was previously available.
Tesla hits record vehicle deliveries and energy deployments in Q3 2025
This was a massive contributor to Tesla’s record-high in vehicle deliveries, as consumers rushed to take advantage of the credit.
There is still some residual impact to be felt as we enter Q4, and there is a potential shock coming to many investors as it could be stronger than what many think:
EV Tax Credit Deliveries Will Continue Through Q4
Despite the credit’s expiration, people will still be able to take advantage of it because the IRS changed the rules mid-quarter.
Prospective buyers can utilize the credit after September 30 if they place an order for an EV and make a marginal payment on the car.
Tesla’s $250 order deposit qualified as the marginal payment, so as long as the order was submitted before the end of the day on September 30, they could still take delivery in Q4 or even Q1 and still take advantage of the credit.
With the Model Y Performance launching in the U.S. on September 30, that undoubtedly contributed to some orders. However, there are likely many people who ordered in the latter portion of Q3 and have not yet taken delivery. These will all contribute to Q4 delivery figures.
Seasonal Holiday Boost
Tesla traditionally has its strongest quarters in Q4, as the company typically introduces initiatives such as price cuts, incentives, and other offers to close out the year strong.
Car buyers are more likely to jump at these offers as well, as gifts for either themselves or others. What Tesla does in the final quarter of the year is usually boosted by whatever types of offers it can make.
Affordable Model Production Ramp
Tesla is likely preparing for the launch of its affordable model, which is essentially a stripped-down Model Y.
Some rumors have been circulating within the community, indicating that the company is nearing the sale of this vehicle, which is coded within Tesla’s website as the “Model Y Standard.”
🚨 Looks like some coding was found on Tesla’s website that seems to hint the affordable Model Y is coming:
-Named “Model Y Standard”
-$39,990 starting priceInitial thoughts: this is completely unconfirmed, but was really hoping Tesla would get this closer to $30,000 https://t.co/RDR0ypQHB3

If Tesla is able to lock in some good pricing on its affordable model, Tesla could see its quarterly figures return to QoQ growth, something that the company has not had in a few years.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025
As per Tesla’s Q3 2025 vehicle delivery and production report, the bulk of the company’s numbers came from its mass-market lineup.

Tesla (NASDAQ:TSLA) reported record-breaking results for the third quarter of 2025, producing 447,450 vehicles and delivering 497,099 units worldwide.
The company also deployed 12.5 GWh of energy storage products, setting a new record in its fast-growing energy business.
Model 3/Y domination
As per Tesla’s Q3 2025 vehicle delivery and production report, the bulk of the company’s numbers came from its mass-market lineup. The Model 3 sedan and Model Y crossover accounted for 435,826 units produced and 481,166 delivered in the quarter. This is quite impressive considering that both the Model 3 and Model Y are still premium-priced vehicles with numerous competitors that are significantly more affordable.
Other models, including the Model S, Model X, and Cybertruck, contributed 11,624 vehicles produced and 15,933 delivered. Beyond vehicles, Tesla’s energy business posted its best quarter to date, deploying 12.5 GWh of storage systems.
Q3 2025 earnings call date
Tesla’s third-quarter results are extremely impressive, and they exceed Wall Street’s estimates by a significant margin. As per Benchmark analyst Mickey Legg, who had a delivery estimate of 442,000 vehicles in Q3, Wall Street consensus was at 448,000 units. Even more optimistic analysts estimated that Tesla would only post deliveries in the mid-460,000s.
Investors will gain further insight later this month when Tesla reports full financials for the quarter. The company will release Q3 2025 earnings after market close on October 22, followed by a Q&A webcast at 4:30 p.m. Central Time.

Elon Musk is halfway towards becoming the world’s first trillionaire
Musk’s fortune remains heavily tied to Tesla, which has rallied nearly 100% since April.

Elon Musk has reached a new milestone by becoming the first individual in history to achieve a net worth of $500 billion. Forbes’ Real-Time Billionaires tracker confirmed the record Wednesday afternoon after Tesla stock gained nearly 4%, adding an estimated $9.3 billion to Musk’s net worth in a single day.
He now sits more than $150 billion ahead of Oracle co-founder Larry Ellison, whose net worth also stands at a very impressive $350 billion.
Tesla stock leads wealth surge
Musk’s fortune remains heavily tied to Tesla, which has rallied nearly 100% since April, when the CEO announced he would step back from outside roles to focus more on the EV maker. The company’s market capitalization is back within 10% of its all-time peak, lifting the value of Musk’s 12% stake to about $191 billion.
Beyond this, his 2018 compensation package, which was rescinded by a Delaware judge last year but is still under appeal, could unlock additional stock worth more than $130 billion if reinstated, Forbes noted. Investors see Musk’s refocused leadership as a stabilizing force for Tesla as it pursues ambitious global growth. Tesla has also proposed a new compensation plan for Musk that could bring the company’s market cap to $8.5 trillion and add an additional $900 billion to the CEO’s net worth.
SpaceX and xAI boost portfolio value
While Tesla drives much of his wealth, Musk’s stakes in SpaceX and xAI have added significant upside to his net worth. SpaceX, his private rocket company, recently hit a $400 billion valuation in a private tender offer, valuing Musk’s 42% stake at $168 billion. Meanwhile, xAI Holdings, which merged with social platform X earlier this year, is worth an estimated $113 billion, giving Musk another $60 billion on paper.
These ventures, combined with Tesla’s resurgence, have pushed Musk’s net worth past the half-trillion-dollar mark and highlighted his reach across multiple industries, from clean energy to space, artificial intelligence, brain implants, and tunneling.
