Plug in America Extends Long-Term Tesla Battery Study to New Model S
Long-time electric vehicle (EV) advocate, Tesla Roadster owner, and Plug in America Chief Science Officer Tom Saxton has been conducting a long-term EV battery study with the goal to gather deep insight on how EV batteries perform (and degrade) over time.
Tom’s long-term battery study has been invaluable not only to the greater EV community but specifically to Tesla fans as well. The take rate for participants for the Tesla Roadster study is close to a 7% sample, while early 85 kWh Tesla Model S owners contributed to a healthy start. In an email correspondence with Tom, he has indicated that he is looking to expand the study to include the new 70 kWh and 90 kWh Model S variants as well as the Model X 90D.
With the EPA recently setting an unprecedented 303.2 mile Highway rating for the redesigned Model S, consumers may want to know what the long-term differences would be between a 90D classic fascia vs a 90D new fascia. Providing a third-party study of the effects of long-term battery health enables all concerned, especially amongst first time Tesla owners / Model 3 reservation holders, with a greater understanding and comfort to know “that Tesla knows what they’re doing.” Furthermore, it gives new EV drivers a sense of comfort when making the switch to electric powered car ownership.

Below are charts for the Model S as captured from Plug in America’s survey.
The first chart that caught my eye is one that plots battery range capacity vs. miles accumulated for that vehicle.
This same chart can be used to also track how a particular respondent’s vehicle matches with the universe of respondents. The vehicle in black on the chart below shows the performance of my vehicle in relation to other respondents’ cars.
The third chart that was of interest is the reliability of certain components, namely the drive unit, battery, and charger found on the Model S. I can’t help but wonder if the increase in reported failures on chargers for 2014 vehicles resulted in Tesla abandoning it for the current 48A charger found on newer Model S and Model X.
Lastly, the inspiration to my exhorting fellow owners to participate in this survey was the chart of participant vehicles.
For as many Model S’ are on the road today, I wonder as to the ability of this study in its current count, to fully report on the vehicle with such a small sample size. If you’re a new 70D or 90D Model S owner, please contribute your data to Plug in America through the Model S battery survey form. It’s fairly straight forward and serves our common purpose.
Tesla continues to improve in every sense, but it’s also wise to run a third party check against Tesla’s claimed figures.
Plug in America is an organization that formed out of the advocates that tried to stop the “murder”of the GM EV1 as told through the documentary, “Who Killed the Electric Car?”. According to the Plug in America site, they aim to accelerate the shift to plug-in vehicles powered by clean, affordable, domestic electricity to reduce our nation’s dependence on petroleum, improve air quality and reduce greenhouse gas emissions.

Tesla preps to build its most massive Supercharger yet: 400+ V4 stalls
The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.
Tesla is preparing to build its most massive Supercharger yet, as it recently submitted plans for an over 400-stall Supercharging station in California, which would dwarf its massive 168-stall location in Lost Hills, California.
The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.
The expansion, adjacent to the existing Eddie World Supercharger, which is currently comprised of 22 older V2 and V3 stalls limited to 150 kW, unfolds across six phases.
Construction on Phase 1 begins later this year with 72 V4 stalls. Subsequent stages will progressively add hundreds more, culminating in over 400 next-generation chargers. Site plans label expansive parking arrays across Phases 1–5 along Calico Boulevard, with Phase 6 design still to be determined.
Tesla is planning an absolutely massive Supercharger expansion in Yermo, California!!
Over the course of 6 phases, Tesla is set to add over 400 V4 stalls in a commercial development known as Eddie World 2.

The project was first flagged by MarcoRP, a notable Tesla Supercharger watcher.
Strategically located midway on I-15 between Los Angeles and Las Vegas, the station targets heavy EV traffic on this high-demand corridor.
The surrounding 20-mile stretch already hosts over 200 high-power stalls (including 40 at 250 kW, 120 at 325 kW, and more), plus 96 in nearby Baker—yet bottlenecks persist during peak travel.
In scale, it eclipses all existing Tesla Superchargers. The current record holder, the solar- and Megapack-powered “Project Oasis” in Lost Hills, California, offers 164 stalls. Barstow’s former leader had 120. Eddie World 2 will be more than double that size, cementing Tesla’s dominance in ultra-high-capacity charging.

Development blends charging with convenience. Architectural drawings show integrated retail: a 10,100 square foot Cracker Barrel, a 4,300 square foot McDonald’s, a 3,800 square foot convenience store, additional restaurants, drive-thrus, outdoor dining, and lease space.
EV-centric features include pull-through bays for Cybertrucks and trailers, ensuring accessibility for larger vehicles and future Semi trucks.

Tesla makes latest move to remove Model S and Model X from its lineup
Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.
Tesla has made its latest move that indicates the Model S and Model X are being removed from the company’s lineup, an action that was confirmed by the company earlier this quarter, that the two flagship vehicles would no longer be produced.
Tesla has ultimately started phasing out the Model S and Model X in several ways, as it recently indicated it had sold out of a paint color for the two vehicles.
Now, the company is making even more moves that show its plans for the two vehicles are being eliminated slowly but surely.
Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.
The change eliminates the $1,000 referral discount previously available to new buyers of these vehicles. Existing Tesla owners purchasing a new Model S or Model X will now only receive a halved loyalty discount of $500, down from $1,000.
The updates extend beyond the two flagship vehicles. New Cybertruck buyers using a referral code on Premium AWD or Cyberbeast configurations will no longer get $1,000 off. Instead, both referrer and buyer receive three months of Full Self-Driving (Supervised).
The loyalty discount for Cybertruck purchases, excluding the new Dual Motor AWD trim level, has also been cut to $500.

These adjustments apply only in the United States, and reflect Tesla’s broader strategy to optimize margins while boosting adoption of its autonomous driving software.
The timing is no coincidence. Tesla confirmed earlier this year that Model S and Model X production will end in the second quarter of 2026, roughly June, as the company reallocates factory capacity toward its Optimus humanoid robot and next-generation vehicles.
With annual sales of the low-volume flagships already declining (just 53,900 units in 2025), incentives are no longer needed to drive demand. Production is winding down, and Tesla expects strong remaining interest without subsidies.
Industry observers see this as the clearest sign yet of an “end-of-life” phase for the vehicles that once defined Tesla’s luxury segment. Community reactions on X range from nostalgia, “Rest in power S and X”, to frustration among long-time owners who feel perks are eroding just as the models approach discontinuation.
Some buyers are rushing orders to lock in final discounts before they vanish entirely.

For Tesla, the move prioritizes efficiency: fewer discounts on outgoing models, a stronger push for FSD subscriptions, and a focus on high-margin Cybertruck trims amid surging orders.
Loyalists still have a narrow window to purchase a refreshed Plaid or Long Range model with remaining incentives, but the message is clear: Tesla’s lineup is evolving, and the era of the original flagships is drawing to a close.

Tesla Australia confirms six-seat Model Y L launch in 2026
Compared with the standard five-seat Model Y, the Model Y L features a longer body and extended wheelbase to accommodate an additional row of seating.
Tesla has confirmed that the larger six-seat Model Y L will launch in Australia and New Zealand in 2026.
The confirmation was shared by techAU through a media release from Tesla Australia and New Zealand.
The Model Y L expands the Model Y lineup by offering additional seating capacity for customers seeking a larger electric SUV. Compared with the standard five-seat Model Y, the Model Y L features a longer body and extended wheelbase to accommodate an additional row of seating.
The Model Y L is already being produced at Tesla’s Gigafactory Shanghai for the Chinese market, though the vehicle will be manufactured in right-hand-drive configuration for markets such as Australia and New Zealand.
Tesla Australia and New Zealand confirmed the vehicle will feature seating for six passengers.
“As shown in pictures from its launch in China, Model Y L will have a new seating configuration providing room for 6 occupants,” Tesla Australia and New Zealand said in comments shared with techAU.
Instead of a traditional seven-seat arrangement, the Model Y L uses a 2-2-2 layout. The middle row features two individual seats, allowing easier access to the third row while providing additional space for passengers.
Tesla Australia and New Zealand also confirmed that the Model Y L will be covered by the company’s updated warranty structure beginning in 2026.
“As with all new Tesla Vehicles from the start of 2026, the Model Y L will come with a 5-year unlimited km vehicle warranty and 8 years for the battery,” the company said.
The updated policy increases Tesla’s vehicle warranty from the previous four-year or 80,000-kilometer coverage.
Battery and drive unit warranties remain unchanged depending on the variant. Rear-wheel-drive models carry an eight-year or 160,000-kilometer warranty, while Long Range and Performance variants are covered for eight years or 192,000 kilometers.
Tesla has not yet announced official pricing or range figures for the Model Y L in Australia.
