A major Swedish study has revealed which electric vehicles hold their battery health the best, and Kia and Tesla came out on top. 

Swedish car broker Kvdbil initiated a test of more than 1,300 used BEVs and plug-in hybrids to determine which models retain the best battery capacity over time. Based on the study’s results, the Kia EV6, Kia e-Niro, and the Tesla Model Y were deemed the best.

Kia and Tesla lead the pack

Kvdbil’s test results are bullish for electric vehicles as a whole. The study showed that eight out of ten used electric cars still had at least 90% of their original battery capacity. Kia’s EV6 and e-Niro finished first and second in the rankings, while Tesla’s Model Y came in third. As per CarInfo data, Sweden currently has 12,148 Kia EV6 registered, while there are 48,488 Model Y.

In a comment to the media, test manager Martin Reinholdsson stated, “They are actually better than we thought. We were a bit surprised that there were so many that were this good.”

In a way, Tesla’s strong performance in the test carries extra weight since the Model Y is one of Sweden’s best-selling EVs, giving the test a much larger sample size compared to Kia’s smaller but highly rated fleet. 

Battery tech, driver habits, and age all play a role

Kvdbil noted that the test’s standout results could be attributed to advanced battery management systems and careful engineering, as noted in a report from the Sweden Herald. At the same time, the study also found that factors like charging routines, driving style, and the age of a vehicle can influence capacity retention.

Rounding out the top ten were entries from Opel, Mazda, Audi, Fiat, Volvo, Citroën, and Volkswagen, as noted in a CarUp report.

This is not the first time that Tesla’s battery prowess has shown its strength. Last year, reports emerged stating that a Tesla Model S 90D from Chesterfield, UK, had traveled 430,000 miles on its original motors and batteries. Over that period, which was comprised of constant Supercharging sessions due to the car being used as an airport taxi, the Model S 90D only lost 65 miles of range.

Tesla just made servicing your vehicle even easier and more convenient than it already is.

All it did was add a new section to its smartphone app.

Tesla has officially launched a new Maintenance tab that estimates the repair date and cost, and uses vehicle data to determine if any part is in need of replacement.

It can be found by accessing the app, going to Service, then hitting Request Service, and then Maintenance.

This can be accessed in your Tesla App by touching:

The new feature is rolling out to iOS users now; we have not heard any confirmation from Android phone users whether they are receiving it too. Since it is not a vehicle capability, we do not believe Tesla will delay the release of the feature to Android phones.

Teslas are already well known for having extremely low maintenance needs, and semi-annual check ups usually only require a tire rotation and some additional windshield washer fluid. There is not a need for things like oil changes or other things that are routinely needed on combustion engine cars due to the lack of parts.

Additionally, the small addition to the company’s smartphone app will help facilitate needs for Service, and could help relieve some congestion, while also streamlining the repair process for technicians.

Tesla to make app change for easier communication following Service

One of the biggest complaints about owning a Tesla is Service wait times, as availability can be extremely limited in some areas. However, Tesla has done a lot to work on increasing the number of Service centers it has, while also working hard to streamline service and make it less time-consuming.

Tesla has aimed to have an F1-style service experience, but it has not worked out that way. With that being said, there are significantly fewer complaints with Tesla’s Service division than in years past. With the presence of Mobile Technicians and more refined Service processes, things are definitely improving.

Elon Musk gave a tough response to a former Tesla employee who spoke out on X about the structure of the CEO’s pay package, arguing that it is an overpayment and would not generate enough shareholder value.

Without a doubt, the biggest issue on the bill at this year’s Tesla Shareholder Meeting in November is that of the pay package that was proposed to CEO Elon Musk.

As the Shareholder Meeting approaches, Tesla is urging those investors to vote in support of Musk’s pay package. So far, the community has been overwhelmingly supportive of giving Musk his massive payday, which could give him $1 trillion in additional holdings if he completes each of the outlined performance tranches.

However, there are a handful of institutional and individual shareholders who have pushed back against the package, either because of its value or because they feel it does not benefit shareholders enough.

Last week, we reported that Institutional Shareholder Services (ISS) advised voting against Tesla’s pay package for Musk. The firm said the payday would give Musk”extraordinarily high pay opportunities over the next ten years,” and it would “reduce the board’s ability to meaningfully adjust future pay levels.”

Additionally, it called the value of the pay package “astronomical.”

On Saturday, a former Tesla employee said on X that Tesla’s proposed pay package for Musk would “barely beat inflation and it would underperform the S&P 500 considerably.” Additionally, he said:

“Sorry, Tesla, some of us (and supposedly, ISS too) simply don’t think that underperforming the S&P 500 this much is worth paying somebody 20 billion dollars worth of company value.

As a fan, I love Tesla, I want it to succeed. As a shareholder, I don’t want Tesla to over-pay for its CEO I strongly believe that the 2025 pay package proposal would over-pay for its CEO, and that other competent CEOs could grow Tesla just as much with way less political drama and cost investors much less that this proposal.”

Musk responded bluntly:

“Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla? It won’t be me.”

It won’t be me.

It seems the worry about Musk’s potential involvement in politics still looms to many, based on the responses to Musk’s post, which frequently mention that as a downside of his last year as Tesla CEO. However, Tesla’s Board confronted that directly.

In its proxy filing after announcing the pay package, Tesla said that it had three commitments, one of which was that the company would “receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

Musk’s previous pay package was approved by shareholders twice, but it never made it to the CEO because of a lawsuit with the Delaware Chancery Court brought forth by a small-time shareholder.

The response from Musk does seem to show that if this time is no different, he will inevitably step down as CEO in the coming years.
