Tesla Model 3 loses only 2.2% of battery range after four years and 100k miles
The longevity of electric vehicles’ battery packs has always been a tricky subject. Companies like Tesla suggest that their cars’ battery packs are designed to last years, while avid EV skeptics would argue that electric vehicles would need a new battery after a few short years of ownership due to degradation. Fortunately, vehicles like the Tesla Model 3 have been around for several years now, and some can already provide valuable data.
Electric vehicle advocate Andy Slye was among the first customers of the Tesla Model 3, taking delivery of the all-electric sedan at a time when only the Long Range RWD variant was available. Since taking delivery of his Model 3 four years ago, the EV owner was able to rack up 100,000 miles in the vehicle. Over its four years in service, the Model 3 proved to be a car that definitely seems designed to go the distance.
The Model 3 owner’s overall thoughts and insights were summarized in a YouTube video, which he uploaded recently on his personal channel. Yet within the Model 3’s 100,000-mile review, the EV owner mentioned something rather remarkable. Over the four years he’s had the vehicle, and over the 100,000 miles the Tesla had traveled, the all-electric sedan had only lost 2.2% of its range. The vehicle was rated at 310 miles when it was new, and now, its full charge remains listed at 303 miles.
Of course, a lot of this is due to the fact that the 100,000-mile Model 3’s battery was well taken care of, as hinted at by the EV owner regularly plugging in the car at home using Tesla’s home charging solution. Overall, however, it’s difficult not to be impressed with the longevity of the Model 3’s battery. Considering the battery’s 2.2% degradation after four years, the Model 3 owner remarked that he is currently not expecting to replace the car’s battery over the ten years he plans on keeping the vehicle.
There are several iconic high-mileage Teslas across the globe, the most notable of which is arguably the Model S P85 driven by Germany-based Hansjörg Gemmingen, who purchased the car in 2014. As of early January 2022, the Model S road warrior had racked up 1.5 million km (932,256 miles) on its odometer. It has been an eventful road to such a feat, however, as the Model S required a battery change at 470,000 km (292,044 miles). Three electric motors were also worn out on the Model S’ journey to 1 million km (621,371 miles).
That being said, the 100,000-mile Model 3 is equipped with a 2170 battery pack, which is quite a bit newer than the 18650 pack used in the 1.5 million km Model S. Overall, it would not be surprising if Tesla’s Model 3 and Model Y 2170 batteries end up lasting very long with very little degradation. Tesla is just getting started, however, as the company is also hard at work in developing its next generation of batteries, the 4680 cells, which would make their debut in the Made-in-Texas Model Y later this year.

Tesla launches Powerwall Lease for affordable home backup
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”
We took a ride on a robotaxi on the Suntrax course and it successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.
Impressive! https://t.co/FVAkzFLz3r
— Ron DeSantis (@RonDeSantis) August 11, 2026
DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
