Tesla battery degradation is not accelerated by frequent Supercharging, which was previously thought, according to an extensive new study.
It has long been believed in the industry that frequent DC fast charging is bad for battery longevity; even Tesla used to warn against it.
But we have never seen strong data that support that assertion when it comes to Tesla vehicles, where we have more data on than any other electric vehicles.
A new report from Recurrent, which has access to data from over 12,500 Tesla vehicles in the US through its software service, now shows clearly that there’s little to no difference in battery degradation between frequent fast charging and rare fast charging:
As you can see from the charts, the data shows the same result for Model 3, and frequent fast charging actually makes long-term battery degradation a bit better on Model Y.
Interestingly, Recurrent focused on the extreme cases. Here’s how they qualified the vehicles that frequently fast charge versus those that rarely fast charge:
We compared cars that fast charge at least 90% of the time to cars that fast charge less than 10% of the time. In other words, people who almost exclusively fast charge their car and people who very rarely fast charge. The results show no statistically significant difference in range degradation between Teslas that fast charge more than 90% of the time and those that fast charge less than 10% of the time.
In Tesla’s owner manual, the automaker doesn’t talk about frequent DC fast charging affecting battery longevity anymore, but it does mention the potential to “decrease slightly” the peak charging rate:
The peak charging rate of the Battery may decrease slightly after a large number of DC Fast Charging sessions, such as those at Superchargers. To ensure maximum driving range and Battery safety, the Battery charge rate is decreased when the Battery is too cold, when the Battery’s charge is nearly full, and when the Battery conditions change with usage and age. These changes in the condition of the Battery are driven by battery physics and may increase the total Supercharging duration by a few minutes over time.
However, they also warned about fast charging under extreme heat or extreme cold, which is not ideal for battery performance. To be fair, extreme heat and cold are also not good for internal combustion engine vehicles.

Lease deals get all the headlines, but 75% of new car buyers still finance their cars, indicating that they want to own their vehicles once the payments are done. If that sounds like you, and you’ve been holding out for relief from sky-high payments, a wave of new EVs are now available with 0% financing — making it one of the best months yet to buy a new EV.
UPDATE: two more sporty electric crossovers make the list!
Every month, Electrek readers looking for great deals on a new EV flock to our lease deal posts. Recently, however, the comments have been asking another crucial question: what about EV deals for the people who want to buy, instead of leas?
You asked, we listened. This roundup is for that 75% of new car buyers who choose to finance their cars instead of lease — so here’s a list of all the 0% financing deals on EVs you can get in September, 2025.

As I put this list together, I realized there were plenty of ways for me to present this information. In the end, I decided to present these deals in alphabetical order, by brand name (make). And, as for which deals are new this month? You’re just gonna have to check the list. Enjoy!
Acura ZDX
2024 Acura ZDX; via Acura.
New for the 2024 model year, the Acura ZDX uses GM Ultium battery and drive technology, but the styling, interior, and infotainment are all Honda, delivering GM-level parts support with Honda-level fit, finish, and quality. Add in standard Apple CarPlay support, 0% financing for up to 72 months, and $7,500 customer cash through September 30th, and the ZDX becomes easily one of the best sporty crossover values on the market.
Chevy Equinox EV
2025 Chevrolet Equinox EV; via GM.
With an impressive combination of affordability, practicality, and advanced features, the Chevy Equinox is a standout EV. And with an EPA-estimated range of up to 319 miles and a starting price under $35,000, it’s no wonder they’re flying off dealer lots.
For well-qualified buyers, Chevrolet is offering 0% APR financing for up to 60 months through GM Financial through September 30th. That offer can be paired with the $7,500 federal EV tax credit (which you can claim at the dealer), along with up to $1,250 in additional discounts for Costco members, depending on membership level.
Dodge Charger
Electric Dodge Charger; via Stellantis.
Dodge is hoping that at least a few muscle car enthusiasts with some extra cash will find their way to a Dodge store and ask for the meanest, loudest, tire-shreddingest muscle car on the dealer’s lot without caring too much about what’s under the hood.
For them, Dodge has the new electric Charger with up to 670 battery-backed horsepower. And if you still owed money on the Hemi you just totaled, Dodge will help get the deal done on its latest retro-tastic ride with a $7,750 retail cash allowance or 0% financing for up to 72 months — and that’s before any dealer discounts.
Ford F-150 Lightning
F-150 Lightning pickup; by Ford.
America’s best-selling electric truck offers V2x technology, a nationwide dealer network, a universe of aftermarket accessories, and a look that blends into the crowd. This month, this proven pickup adds 0% interest financing for up to 72 months. Ford Pro customer can get access to advanced telematics and, in some cases, even get help sourcing additional grants and rebates, too.
The biggest of GM’s Ultium-based EVs are seriously impressive machines, with shockingly quick acceleration, plus on-road handling that seems to defy the laws of physics once you understand that these are, essentially, medium-duty trucks. This month, GMC is doing its best to move out its existing inventory with 0% financing for well-qualified buyers plus $1,250 in discounts for select Costco members. So, if you’re a fan of heavy metal you’ll definitely want to stop by your local GMC dealer and give the Hummer EV a test drive.
2025 Honda Prologue Elite in Snowfall Pearl, via Honda.
Like the Acura ZDX at the top of this list, the Honda Prologue was blends the excellent GM Ultium EV platform with Honda sensibilities and Apple CarPlay to create a winning combination. It’s no surprise that it’s one of the top-selling electric crossovers — and to move out as many as possible before the $7,500 federal tax credit goes away, Honda is offering 0% APR for up to 60 plus up to an additional $2,000 in Honda Loyalty or Conquest cash.
Hyundai IONIQ 6
Hyundai IONIQ 6; via Hyundai.
The last of the streamliners, the IONIQ 6 has influences from Ferry Porsche and Raymond Loewy without looking like a copy of either. In addition to being a future classic, it’s efficient, comfortable, quick, offers up to 361 miles of range, can charge just about anywhere, and (now through the end of the month), can be financed with 0% interest for up to 48 months or $7,500 in customer bonus cash on all trims.
If you’re flexible on color, Hyundai dealers with “aged inventory” will give you an extra $1,000, for $8,500 total incentive dollars on your IONIQ 6.
Jeep Wagoneer S
Jeep Wagoneer S; via Stellantis.
The Jeep Wagoneer S is a slick, capable, street-oriented EV that’s been inexplicably saddled with a sloping roof and spoiler that eats away at the electric SUV’s ultimate utility (that’s the “U” part), but if you can get past that minor caveat, this first-ever battery-powered Jeep is ready to deliver. With $7,750 retail cash allowance or 0% financing for up to 72 months before dealer discounts through September 30th, the Wagoneer S might just be the best EV deal going.
Kia Niro EV
2025 Kia Niro EV; via Kia.
Kia is doing a phenomenal job moving its supercar-baiting EV6 and ultra-capable EV9 family trucksters, but the under-mentioned and underrated little Niro EV seems like it could use a little help. To that end, Kia is offering 0% interest financing or up to $7,500 customer cash on select examples of the little urban runabout now through September 30th.
Lexus RZ
Lexus RZ 450e; via Toyota.
Starting at “just” $55,175, the Lexus RZ promises up to 266 miles of EPA-rated range from a 72.8 kWh battery in the base RZ300e (and 224 from the top-shelf RZ450e). With up to 308 hp and over 195 lb-ft of instant, all-electric torque, the RZ promises to be one Lexus’ sportier rides in any trim.
This month, several Lexus dealers are advertising interest-free financing on select RZ models for up to 72 months. Check with your local Lexus dealer for more informatoin.
Nissan Ariya
Nissan Ariya; via Nissan.
I’ve already said that the Nissan Ariya didn’t get a fair shake. If you click that link, you’ll read about a car that offers solid driving dynamics, innovative interior design, and all the practicality that makes five-passenger crossovers the must-haves they’ve become for most families. With up to 289 miles of EPA-rated range, Tesla Supercharger access, and 0% interest from Nissan for up to 72 months or up to $10,000 Customer Cash (that’s not a typo) undecided EV buyers could do a lot worse than to give the Ariya a chance to win them over.
Polestar 3
Polestar 3; via Polestar.
Sleek, Scandinavian, and seriously quick, the Polestar 3 is the lovechild of Swedish brand Volvo and Chinese brand Geely’s billions. As such, it delivers both Scandinavian style and high-tech substance with dual-motor power, a minimalistic, luxurious cabin, and Android Auto baked right in. The Polestar 3 was designed to turn heads while keeping daily driving effortless, and through the month of September, it’s sure to turn even more heads with 0% financing for up to 72 months through Polestar Financial Services and a $10,000 Clean Vehicle Incentive in some markets.
Put it all together, and the Polestar 3 stands out as one of the most compelling premium EV SUV deals of the month.
Subaru Solterra
Subaru Solterra EV; via Subaru.
The first-ever electric Subaru had a rocky start (no pun intended), but this off-road-ready sibling of the Toyota bZ4X seems like a solid mid-size electric crossover with some outdoorsy vibes and left-leaning granola style that offers more than enough utility to carry your mountain bikes to the trail or your inflatables out to the pond. Add in 227 miles of range, some big discounts, and 0% financing for up to 72 months, and this should be a great month for electric Subaru fans to drive home in a new Solterra.
Volkswagen ID.4
VW ID.4; via Volkswagen.
One of the most popular legacy EVs both in the US and Europe, the ID.4 offers Volkswagen build quality and zippy around-town handling. Everyone I know who has one loves it, and VW dealers are getting aggressive with discounts, making this fast-charging, 291 mile EPA-rated range, 5-star safety rated EV a value proposition that’s tough to beat.
This month, get a Volkswagen ID.4 with 0% financing for up to 72 months or up to $5,000 customer cash. You’ll need to do some math to see which offer works best for you.

True to Lamborghini’s legacy of speed and excess, the first battery-electric vehicle to wear the raging bull is also the fastest of its kind. Only this time, the badge isn’t on a car — it’s on a personal watercraft. Meet the all-new Seabob SE63 jet sled.
Co-developed with the Italian supercar brand, the Lamborghini-badged Seabob SE63 features a more powerful jet propulsion system than any of the company’s existing personal jet sleds, and is fitted with a carbon fiber motor shaft as a further nod to the Italian luxury brand’s high-performance heritage.
The riding experience is not just ‘a bit faster’, but thrillingly intense and unrestrained. Acceleration off the start line delivers an immediate adrenaline rush. Thrust, agility, top speed: everything is designed for maximum performance and pure emotion.
The new SE63 backs up those claims with a 6.3 kW (~8.5 hp) electric motor. And, while that hardly makes it a supercar, in the world of ePWCs, it’s enough to make the SE63 a monster. The SE63 also features a bigger, more energy-dense battery than other Seabobs, a combination good for up to 60 minutes of go-fast, water-based fun.
Seabob SE63 Lamborghini
The SE63 can recharge its batteries with a standard power outlet in just 1.5 hours, and be back on the water for even more fun in the sun.
The Seabob SE63 made its debut earlier this week at the Cannes Yachting Festival. Production is set to begin in early 2026, meaning you’ll be able to get yours just in time for the summer 2026 beach season. Prices have yet to be announced – but, like any Lamborghini product, if you have to ask you probably can’t afford it.
Check out the world premier of the Seabob SE63 for Automobili Lamborghini (the sled’s official name) in the video, below, then let us know what you think of the brand’s first BEV in the comments.

A duo of Tesla shareholder-influencers tried to complete Elon Musk’s coast-to-coast self-driving ride that he claimed Tesla would be able to do in 2017 and they crashed before making it about 60 miles.
In 2016, Elon Musk infamously said that Tesla would complete a fully self-driving coast-to-coast drive between Los Angeles and New York by the end of 2017.
The idea was to livestream or film a full unedited drive coast-to-coast with the vehicle driving itself at all times.
We are in 2025 and Tesla never made that drive.

Despite the many missed autonomous driving goals, many Tesla shareholders believe that the company is on the verge of delivering unsupervised self-driving following the rollout of its ‘Robotaxi’ fleet in Austin, which requires supervision from Tesla employees inside the vehicles, and improvements to its “Full Self-Driving” (FSD) systems inside consumer vehicles, which is still only a level 2 driver assist system that requires driver attention at all times as per Tesla.
Two of these Tesla shareholders and online influencers attempted to undertake a coast-to-coast drive between San Diego, CA, and Jacksonville, FL, in a Tesla Model Y equipped with the latest FSD software update.
They didn’t make it out of California without crashing into easily avoidable road debris that badly damaged the Tesla Model Y:
In the video, you can see that the driver doesn’t have his hands on the steering wheel. The passenger spots the debris way ahead of time. There was plenty of time to react, but the driver didn’t get his hands on the steering wheel until the last second.
In a follow-up video, the two Tesla influencers confirmed that the Model Y had a broken sway bar bracket and damaged suspension components. The vehicle is also throwing out a lot of warnings.
They made it about 2.5% of the planned trip on Tesla FSD v13.9 before crashing the vehicle.
Electrek’s Take
Tesla shareholders used to discuss this somewhat rationally back in the day, but now that Tesla’s EV business is in decline and the stock price depends entirely on the self-driving and robot promises, they no longer do.
I recall when Musk himself used to say that when you reach 99% self-driving, it is when the “march of the 9s” begins, and you must achieve 99.999999999% autonomy to have a truly useful self-driving system. He admitted that this is the most challenging part as the real-world is unpredictable and hard to simulate – throwing a lot of challenging scenario at you, such as debris on the road.
That’s where Tesla is right now. The hard part has just started. And there’s no telling how long it will take to get there. If someone is telling you that they know, they are lying. I don’t know. My best estimate is approximately 2-3 years and a new hardware suite.
However, competition, mainly Waymo, began its own “march of the 9s” about five years ago.
Tesla is still years behind, and something like this drive by these two Tesla influencers proves it.
I was actually in a similar accident in a Tesla Model 3 back in 2020. I rented a Model 3 on Turo for a trip to Las Vegas from Los Angeles.
I ended up driving over a blown-out truck tire in the middle of the road like this. I was Autopilot, but I don’t know if the car saw it. I definitely saw it, but it was a bit late as I was following a truck that just drove over it. I had probably less than 2 seconds to react. I applied the brakes, but my choices were driving into a ditch on the right or into a car in the left lane.
I managed to reduce the force of the impact with the braking, but the vehicle jumped a bit like in this video. There wasn’t really any damage to the front, but the bottom cover was flapping down. I taped it together at the next gas station and I was able to continue the trip without much issue.
However, after returning it to the Turo owner and having the suspension damage evaluated by Tesla, the repair job was estimated to be roughly $10,000. I wouldn’t be surprised if there’s a similar situation with this accident.
