Tesla battery predicted to have 80% capacity after 840,000 km (521,000 mi)

Published

An updated battery study based on crowdsourced data from Model S and Model X owners suggests that Tesla’s battery pack will still have 80% capacity after reaching 840,000 kilometers (521,952 miles), or nearly 1 million kilometers driven.

An online spreadsheet created by Matteo and maintained by Merijn Coumans via the Dutch-Belgium Tesla Forum tracks battery degradation being experienced by roughly 900 Tesla drivers from around the world. Using a linear progression model, the spreadsheet compiles various data points to create a trend line that suggests remaining battery capacity for a Tesla Model S and Model X over its lifetime.

This information is important to many Tesla owners and would-be buyers as it provides insight to expected driving range a vehicle could have (per single charge) over time.

The trend line seen in the chart has a slope of 60,000 km (40,000 miles) per 1 percent of 50,000 km (30,000 miles), meaning that on average the battery will degrade by 1 percent every 50,000 km driven. According to Maarten Steinbuch’s blog post, a Tesla Model S or Model X will still retain 92% of its battery capacity at 240,000 km (150,00 miles). By comparison, an internal combustion engine vehicle is expected to reach its end of life at around 220,000 km (140,000 miles).

Data revealed in the crowdsourced battery survey follows suit with recent reports that a Finnish taxi driver who crossed the 400,000 km (250,000 mile) mark in his Tesla Model S experienced only 7 percent degradation.

In addition, Tesloop, a city-to-city Tesla shuttle service available in Southern California, had its first vehicle reach the 483,000 kilometer (300,000 mile) mark with only $11,000 in vehicle maintenance costs.

“Over the last two years, we have seen that that electric, supercharged vehicles can be deployed at utilization levels unheard of with gas vehicles,” Tesloop said in a statement. “And while saving over $60,000 on fuel and maintenance is a substantial economic win, we feel the bigger win is that this car is ready for another 900,000 miles over the next 6 years under its current warranty.”

It’s worth noting that the battery degradation data we’re seeing is from Tesla’s 18650 cell and not the company’s newest 2170 cell being used on the Model 3. Based on Tesla’s comment that its 2170 cell has improved energy density and an all-around more efficient design, it wouldn’t come as a surprise if Model 3 and future fleet’s using this cell type can support more battery cycles, reach 1 million miles of use, and still retain over 80% of its original capacity.

Based on these drivers’ stories, and battery data being compiled by Tesla drivers from around the world, it seems clear that a Tesla has quadruple the lifespan of any ICE car, and can outlast it by nearly ten-fold.

Tesla Model Y L is gaining momentum in China’s premium segment

This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.

Tesla’s domestic sales in China held steady in November with around 73,000 units delivered, but a closer look at the Model Y L’s numbers hints at an emerging shift towards pricier variants that could very well be boosting average selling prices and margins. 

This suggests that the addition of the Model Y L to Tesla China’s lineup will not result in a case of cannibalization, but a possible case of “premiumization” instead.

Tesla China’s November domestic numbers

Data from the a Passenger Car Association (CPCA) indicated that Tesla China saw domestic deliveries of about 73,000 vehicles in November 2025. This number included 34,000 standard Model Y units, 26,000 Model 3 units, and 13,000 Model Y L units, as per industry watchers. 

This means that the Model Y L accounted for roughly 27% of Tesla China’s total Model Y sales, despite the variant carrying a ~28% premium over the base RWD Model Y that is estimated to have dominated last year’s mix.

As per industry watcher @TSLAFanMtl, this suggests that Tesla China’s sales have moved towards more premium variants this year. Thus, direct year-over-year sales comparisons might miss the bigger picture. This is true even for the regular Model Y, as another premium trim, the Long Range RWD variant, was also added to the lineup this 2025.

November 2025 momentum

While Tesla China’s overall sales this year have seen challenges, the Model Y and Model 3 have remained strong sellers in the country. This is especially impressive as the Model Y and Model 3 are premium-priced vehicles, and they compete in the world’s most competitive electric vehicle market. Tesla China is also yet to roll out the latest capabilities of FSD in China, which means that its vehicles in the country could not tap into their latest capabilities yet. 

Aggregated results from November suggest that the Tesla Model Y took the crown as China’s #1 best-selling SUV during the month, with roughly 34,000 deliveries. With the Model Y L, this number is even higher. The Tesla Model 3 also had a stellar month, seeing 25,700 deliveries during November 2025.

Tesla Cybertruck earns IIHS Top Safety Pick+ award

To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.

The Tesla Cybertruck has achieved the Insurance Institute for Highway Safety’s (IIHS) highest honor, earning a Top Safety Pick+ rating for 2025 models built after April 2025. 

The full-size electric pickup truck’s safety rating is partly due to the vehicle’s strong performance in updated crash tests, superior front crash prevention, and effective headlights, among other factors. To commemorate the accolade, the official Cybertruck account celebrated the milestone on X.

Cybertruck’s IIHS rating

As per the IIHS, beginning with 2025 Cybertruck models built after April 2025, changes were made to the front underbody structure and footwell to improve occupant safety in driver-side and passenger-side small overlap front crashes. The moderate overlap front test earned a good rating, and the updated side impact test also received stellar marks.

The Cybertruck’s front crash prevention earned a good rating in pedestrian scenarios, with the standard Collision Avoidance Assist avoiding collisions in day and night tests across child, adult crossing, and parallel paths. Headlights with high-beam assist compensated for limitations, contributing to the top award.

Safest and most autonomous pickup

The Cybertruck is one of only two full-size pickups to receive the IIHS’ Top Safety Pick + rating. It is also the only one equipped with advanced self-driving features via Tesla’s Full Self-Driving (Supervised) system. Thanks to FSD, the Cybertruck can navigate inner city streets and highways on its own with minimal supervision, adding a layer of safety beyond passive crash protection.

Community reactions poured in, with users praising the vehicle’s safety rating amidst skepticism from critics. Tesla itself highlighted this by starting its X post with a short clip of a Cybertruck critic who predicted that the vehicle will likely not pass safety tests. The only question now is, of course, if the vehicle’s Top Safety Pick+ rating from the IIHS will help the Cybertruck improve its sales.

Tesla stands to gain from Ford’s decision to ditch large EVs

Tesla is perhaps the biggest beneficiary of Ford’s decision, especially as it will no longer have to deal with the sole pure EV pickup that outsold it from time to time: the F-150 Lightning.

Ford’s recent decision to abandon production of the all-electric Ford F-150 Lightning after the 2025 model year should yield some advantages for Tesla.

The Detroit-based automaker’s pivot away from large EVs and toward hybrids and extended-range EVs that come with a gas generator is proof that sustainable powertrains are easy on paper, but hard in reality.

Tesla is perhaps the biggest beneficiary of Ford’s decision, especially as it will no longer have to deal with the sole pure EV pickup that outsold it from time to time: the F-150 Lightning.

Here’s why:

Reduced Competition in the Electric Pickup Segment

The F-150 Lightning was the Tesla Cybertruck’s primary and direct rival in the full-size electric pickup market in the United States. With Ford’s decision to end pure EV production of its best-selling truck’s electric version and shifting to hybrids/EREVs, the Cybertruck faces significantly less competition.

This could drive more fleet and retail buyers toward the Cybertruck, especially those committed to fully electric vehicles without a gas generator backup.

Strengthened Market Leadership and Brand Perception in Pure EVs

Ford’s pullback from large EVs–citing unprofitability and lack of demand for EVs of that size–highlights the challenges legacy automakers face in scaling profitable battery-electric vehicles.

This can boost consumer confidence in Tesla’s long-term ecosystem over competitors retreating to hybrids. With Ford making this move, it is totally reasonable that some car buyers could be reluctant to buy from other legacy automakers.

Profitability is a key reason companies build cars; they’re businesses, and they’re there to make money.

However, Ford’s new strategy could plant a seed in the head of some who plan to buy from companies like General Motors, Stellantis, or others, who could have second thoughts. With this backtrack in EVs, other things, like less education on these specific vehicles to technicians, could make repairs more costly and tougher to schedule.

Potential Increases in Market Share for Large EVs

Interestingly, this could play right into the hands of Tesla fans who have been asking for the company to make a larger EV, specifically a full-size SUV.

Customers seeking large, high-capability electric trucks or SUVs could now look to Tesla for its Cybertruck or potentially a future vehicle release, which the company has hinted at on several occasions this year.

With Ford reallocating resources away from large pure EVs and taking a $19.5 billion charge, Tesla stands to capture a larger slice of the remaining demand in this segment without a major U.S. competitor aggressively pursuing it.
