Tesla battery predicted to have 80% capacity after 840,000 km (521,000 mi)
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 just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.
The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.
The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.
With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.
However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.
Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.
Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.
Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.
Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.
It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.
As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.
The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.
It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.
Tesla’s ‘megacasts’ are key to massive build quality improvements
While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.
This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.
Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent
Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.
Tesla reported it delivered 467,762 Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.
🚨 BREAKING: Tesla delivered 480,126 vehicles in Q2, ANNIHILATING Wall Street expectations of 406,000. Production was reported at 451,758.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.
Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.
For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.
Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.
Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.
