With the rollout of the Model 3 “refresh,” Tesla has also updated the range of the Model X Long Range Dual Motor AWD and the Model S Performance. Both vehicles are now seemingly closing in on the 400-mile mark, which is quite remarkable in their own right considering that the Model S and Model X still utilize 18650 cells, the same battery form factor that the company used in the original Tesla Roadster.

The Tesla Model X Long Range Dual Motor AWD, which was already impressive with its previous EPA-estimated range of 351 miles per charge, now holds an EPA-estimated range of 371 miles. This speaks a lot about Tesla’s constant improvements to the vehicle, especially considering that the Model X is the heaviest and largest of the electric car maker’s current lineup of EVs.

The same is true for the Model S Performance, the quickest of the company’s current offerings with its supercar-beating 0-60 mph time of 2.3 seconds. While the Model S Performance is not tuned for maximum efficiency like its Long Range Dual Motor AWD counterpart, the vehicle now boasts a range of 387 miles per charge. That’s over twice the EPA range of the Porsche Taycan Turbo S, which has an EPA-estimated range of 192 miles.

The Model S Performance, like the Model X Long Range, utilizes a 100 kWh battery pack comprised of 18650 cells. The size of the two vehicles’ battery packs has remained identical to their initial Model X 100D and Model S P100D iterations, which boasted 295 miles and 315 miles of range per charge, respectively.

Considering that the Model X Long Range and Model S Performance have kept their battery pack size and 18650 cell form factor, it is evident that the massive range improvements Tesla rolled out over the years have been the result of serious optimizations in the vehicles’ design. These include suspension improvements that were rolled out in 2019 in the form of the Model S and Model X’s “Raven” updates, as well as constant battery cell improvements, as per statements from CEO Elon Musk.

The fact that the Model S Performance and the Model X Long Range are now closer to 400 miles while still having the same 100 kWh battery pack and 18650 cells is very impressive. Even more importantly, these developments hint at the exciting specs of Tesla’s next-generation vehicles, which will be using the company’s custom-designed 4680 cells, which have 5x the volume of the Model 3 and Model Y’s 2170 cells, which are, in turn, already larger and more energy-dense than the Model S and Model X’s 18650 cells.

Tesla skeptics will hate what this new reliability study says

In a notable shift for electric vehicle perceptions, Tesla has emerged as a standout performer in the latest iSeeCars longevity study, which analyzed over 174 million used vehicles.

The data reveals that Tesla models have a 4.6 percent chance of reaching 250,000 miles, matching the industry average of 4.8 percent and tying for sixth place among 32 brands. This positions Tesla ahead of many established names, including Subaru (2.3 percent, roughly half of Tesla’s rate), Nissan (2.4 percent), Mazda, BMW, Mercedes-Benz, and Porsche.

Toyota leads with an impressive 17.8 percent likelihood, followed by Lexus (12.8 percent), Honda, and Acura. Yet Tesla’s result stands out for a relatively young EV brand. Experts attribute this to the inherent simplicity of electric powertrains: fewer moving parts mean no oil changes, timing belts, or complex engine components that typically fail in internal combustion vehicles.

Fewer things to maintain means fewer things to break, and ultimately, fewer things to go wrong.

This design advantage helps Teslas defy unfounded skepticism about battery longevity and overall durability, two things that have plagued the company from outsider perspectives without much proof.

The iSeeCars reliability ratings further bolster Tesla’s case. The Tesla Model S earns a strong 7.9/10 reliability score, ranking No. 1 out of 35 most reliable electric cars. It boasts a predicted average lifespan of about 154,419 miles (around 16.9 years) and a 21.9 percent chance of hitting 200,000 miles.

Tesla, as an electric car brand, also scores 7.9/10 overall, securing the top spot among electric vehicle manufacturers in several luxury and segment categories.

Real-world examples reinforce the data. High-mileage Teslas, including Model S vehicles exceeding one million miles, demonstrate that EVs can endure when properly maintained. Owners report minimal mechanical issues beyond typical wear items like tires and brakes, which regenerative braking often extends.

This performance challenges narratives around EV reliability, especially amid mixed reports from other sources like Consumer Reports or regional inspections. iSeeCars‘ massive dataset emphasizes long-term durability over short-term defect rates, painting Tesla as a leader in sustainable, high-mileage ownership.

For buyers prioritizing longevity and low maintenance, Tesla’s results signal strong value. While no brand is flawless, factors like driving habits, climate, and software updates matter—the numbers suggest Tesla belongs among the elite for those seeking vehicles built to last.

As EV adoption grows, this iSeeCars data underscores Tesla’s engineering edge in creating enduring, future-proof automobiles.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.

Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.

There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.

Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.

Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.

Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.

He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.

For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.

The Tesla Roadster unveiling could be coming “in a few weeks,” according to the company’s Chief Designer Franz von Holzhausen, who said at the Tesla Takeover Europe Event in Austria that the all-electric hypercar could finally make its way to the production line after years of anticipation.

Von Holzhausen delivered the news just days after The Information reported that Tesla planned to push the Roadster unveiling to August. It was slated for both April and May of this year, but now it seems the company is leaning toward a late Summer event to cap off the heat with perhaps its most anticipated vehicle of all-time.

Franz has been with Tesla since 2008, and has played a pivotal role in the iconic design language the company has utilized with its vehicles. Speaking to the crowd in Austria virtually, von Holzhausen’s comments injected fresh excitement into a project that has been plagued by delays for nine years.

The second-generation Roadster promises to redefine supercar standards. Tesla’s website still highlights ambitious targets: 0-60 mph in under 1.9 seconds (with optional SpaceX thruster pack potentially achieving 1.1 seconds or less), a top speed exceeding 250 mph, and a range of about 620 miles.

Equipped with a tri-motor all-wheel-drive setup delivering over 1,000 horsepower, the four-seater aims to blend blistering acceleration, everyday usability, and innovative features like cold gas thrusters for short-hop capabilities, technology that will combine the project with SpaceX.

But years after the company promised to start production, which was slated for 2020, the timeline for the Roadster has continued to shift.

Tesla has strung along those who have put $50,000 deposits down, as well as fans and enthusiasts of the company who have been long awaiting the company to bring forth a car truly designed for the human driver, and not autonomy. The Roadster is more than just a halo vehicle for Tesla; it showcases the company’s ability to push the boundaries while incorporating synergies from other Musk companies.

However, it has to make it to production, which is something Musk and Co. have pushed back repeatedly.

As Tesla navigates Robotaxi development and broader autonomy goals, the Roadster serves as a reminder of its performance roots. If von Holzhausen’s timeline holds, fans could witness this engineering marvel by late June or early July 2026. Whether a full unveiling, demo, or initial deliveries, it marks a milestone for electric supercars.
