Is Tesla being modest on its Model S P100D EPA-rated range?
The EPA has published range ratings for Tesla’s latest long range 100 kWh Model S P100D, giving the vehicle a rating of 305.9 miles for city driving and 346.9 miles for highway. The EPA applies these numbers to a formula that combines the weighted average of City and Highway range values to determine an overall range rating for a vehicle. City values are weighted at 55% while the Highway value is given a weight of 45%. Presumably, this is how Tesla determined the 315 miles of EPA-rated range per single charge for its Model S P100D, however the math just doesn’t add up. In fact, Tesla may actually be understating its range by 2.5% or approximately 8 miles. The Model S P100D really has a range of 323 miles of range per single charge.
Is Tesla being modest on its P100D range?
The folks at InsideEVs have uncovered the latest range data published by the EPA for the 2016 Tesla Model S P100D. Comparing the range differences between the P90D and the P100D, we can see that Tesla has been able to produce a staggering 45 miles of extra range from adding an extra 10 kWh of battery capacity.

We already know that the P100D is capable of producing staggering performance numbers – having recently bested an all wheel drive Lamborghini Huracan in a heads up drag race – by redesigning the internal components of its 100 kWh battery pack. But what we’re seeing based on the EPA-published City and Highway numbers is that Tesla may have voluntarily selected a lower range estimate.
Using the EPA weighted formula to calculate range:
Miles of range = 1/(0.55/City + 0.45/Highway)
We can see that a Model S P90D has a rounded 270 miles of total range by plugging in the City and Highway values into the formula. Tesla Model S P90D = 1/(0.55/259.6 + 0.45/283.4) ~= 269.796 miles
Now if we’re to plug in the range numbers for the new Model S P100D, we see that the computed range is actually 323.083 miles as opposed to Tesla’s published 315 miles of range. That’s right. It would appear that the new 100 kWh battery is even more remarkable than what’s being stated. This, perhaps, could be one of the reasons why Tesla CEO Elon Musk has hinted at not producing a battery beyond 100 kWh of capacity.
Regardless of the reason, we can only imagine what’s to come in terms of performance and range improvements with Tesla’s upcoming Model 3 and beyond.
Tesla stock (NASDAQ: TSLA) has landed an elusive “must own” status from Wall Street firm Melius, according to a new note released early this week.
Analyst Rob Wertheimer said Tesla will lead the charge in world-changing tech, given the company’s focus on self-driving, autonomy, and Robotaxi. In a note to investors, Wertheimer said “the world is about to change, dramatically,” because of the advent of self-driving cars.
He looks at the industry and sees many potential players, but the firm says there will only be one true winner:
“Our point is not that Tesla is at risk, it’s that everybody else is.”
The major argument is that autonomy is nearing a tipping point where years of chipping away at the software and data needed to develop a sound, safe, and effective form of autonomous driving technology turn into an avalanche of progress.
Wertheimer believes autonomy is a $7 trillion sector,” and in the coming years, investors will see “hundreds of billions in value shift to Tesla.”
A lot of the major growth has to do with the all-too-common “butts in seats” strategy, as Wertheimer believes that only a fraction of people in the United States have ridden in a self-driving car. In Tesla’s regard, only “tens of thousands” have tried Tesla’s latest Full Self-Driving (Supervised) version, which is v14.
Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad
When it reaches a widespread rollout and more people are able to experience Tesla Full Self-Driving v14, he believes “it will shock most people.”
Citing things like Tesla’s massive data pool from its vehicles, as well as its shift to end-to-end neural nets in 2021 and 2022, as well as the upcoming AI5 chip, which will be put into a handful of vehicles next year, but will reach a wider rollout in 2027, Melius believes many investors are not aware of the pace of advancement in self-driving.
Tesla’s lead in its self-driving efforts is expanding, Wertheimer says. The company is making strategic choices on everything from hardware to software, manufacturing, and overall vehicle design. He says Tesla has left legacy automakers struggling to keep pace as they still rely on outdated architectures and fragmented supplier systems.
Tesla shares are up over 6 percent at 10:40 a.m. on the East Coast, trading at around $416.

Tesla on track to break Volkswagen’s historic record in Norway: report
As per Elbil Statistik, Tesla reached 26,127 Norwegian sales so far this year, without counting 13 imported Cybertrucks.
Tesla is surging towards a historic milestone in Norway this month, putting the company on track to break Volkswagen’s long-standing annual sales record in the country.
With 3,732 units sold in November alone and more than 26,000 delivered year-to-date, Tesla is poised to become one of the most successful car brands in Norway’s modern automotive history.
Tesla closes in on Norway’s all-time sales record
Norway’s demand for Tesla vehicles has intensified as drivers attempt to beat the incoming VAT changes on electric cars. Once the VAT changes take effect, the best-selling Model Y could become 50,000 kroner more expensive, as noted in a CarUp report. This has likely caused a rise in sales for Tesla in the country as of late.
As per Elbil Statistik, Tesla reached 26,127 Norwegian sales so far this year, without counting 13 imported Cybertrucks. This places the brand just hundreds of units away from surpassing Volkswagen’s 2016 record of 26,572 annual registrations. With one month left in 2025, it seems all but certain that Tesla will overtake Volkswagen’s all-time record in Norway.
Tesla sees challenges in Sweden
While Norway is delivering historic results, Tesla’s Swedish performance has moved in the opposite direction. Registrations have dropped 68% this year, totaling just 6,147 vehicles so far. November has seen only 291 deliveries, highlighting challenges in the domestic market’s momentum.
Tesla Sweden is also still dealing with an increasing number of union-backed protests and blockades. Despite the pressure, however, Tesla Sweden has maintained its stance, IF Metall union chair Marie Nilsson to urge Elon Musk to reconsider his perception of organized labor. She also stated that Swedish unions are not like their American counterparts, as they are not as combative.
Tesla Full Self-Driving has officially landed in a new country today, its seventh overall after it launched in both Australia and New Zealand earlier this year.
On Sunday, Tesla owners in South Korea reported that the company’s Full Self-Driving (Supervised) had started arriving in their vehicles. Owners reported that it was v14.1.4, which is not the latest version available in other countries, but is one of the most recent releases Tesla has deployed to drivers:

Tesla Full Self-Driving has launched in South Korea; the 7th country to have FSD https://t.co/X6gm1SyoxV
— TESLARATI (@Teslarati) November 23, 2025
This marks the seventh country in which Tesla has enabled its Full Self-Driving suite, following the United States and Puerto Rico, Canada, China, Mexico, Australia, and New Zealand.
Tesla launched Full Self-Driving most recently in Australia and New Zealand about three months ago. The expansion is a major breakthrough for the company as it aims to launch Full Self-Driving on a global scale.
However, the company’s biggest challenge thus far has been getting European regulatory agencies to handle the red tape that has inhibited Tesla from launching its semi-autonomous driving suite on the continent. Recently, it admitted that it sees a pathway through Dutch regulatory bodies, which seem to be the most willing to work with Tesla to get FSD in Europe.
Tesla Full Self-Driving appears to be heading to Europe soon
The company said that it has driven over 1 million kilometers safely on European roads across 17 different countries in internal testing. But its path to success will be by “partnering with the Dutch approval authority RDW to gain exemption for the feature. This involves proving compliance with existing regulations (UN-R-171 DCAS) + filing an exemption (EU Article 39) for yet-to-be-regulated behaviors like Level 2 systems off-highway, system-initiated lane changes with hands-off the wheel, etc.”
Perhaps the expansion into Europe will be the biggest challenge for Tesla, but it could also yield major results and advantages for the company moving forward. Tesla said it hopes to have FSD available in Europe sometime early next year.
For now, the expansion in South Korea is the latest win for Tesla and its self-driving efforts. In the U.S., it now turns its focus toward fully autonomous operation, as it works with state agencies to launch Robotaxi outside of Texas, California, and most recently, Arizona.
