Tesla: our batteries only lose 10% after 320,000 km

Tesla: our batteries only lose 10% after 320,000 km


As if to respond to Hyundai's provocations, Tesla included in the latest Impact Report (the report on the environmental impact of its products) a note about the reliability of its batteries. There is talk of a good 200,000 miles, about 322,000 kilometers, with a loss in overall capacity limited to 10%. These numbers are very significant, considering that already in thermal engine cars few reach similar mileage, at least in Europe. The question is different in the USA, where because of the distances the kilometers (or miles) accumulated by cars are many more.

The deterioration in battery capacity remains a very important issue for electric cars which still makes them more like notebooks and smartphones. As with portable devices, even hybrid and electric devices lose autonomy with the passage of time and recharge cycles. But how quickly this problem occurs depends on many factors, starting with the materials behind the batteries themselves. Tesla, thanks to the decades of experience it boasts in this sector, is ahead of the competition and the independent research carried out on the same specification proves it.

The American site Electrek has in fact compared the overall performance of the batteries of a used Model X compared to the new vehicle. The result was very similar to the announcements of Elon Musk's house: even after 400,000 miles (well more than the official 200,000) the overall capacity was around 90%. The same vehicle, however, suffered other unforeseen events on the battery side, which were replaced as they were no longer reliable during recharging (it happened to drop to zero by chance). However, the replacement took place under warranty.

It should be noted that all the numbers reported so far concern only Model S and Model X, while the most recent Model 3 (click here to find our test) has batteries designed to last longer: 500,000 miles, over 800,000 kilometres. And with the new models, Tesla aims to touch one million miles thanks to the new batteries that will be installed soon. Should they succeed, this would make the purchase of one of their cars even more attractive. Not only when new, but also on the second-hand market.

Elon Musk's official Tesla salary dropped to zero in 2020 — but he hasn't accepted his paychecks in years anyway

  • In 2019, the company said it eliminated altogether the earning and accrual of his base salary.

    Musk's 2020 salary dropped to zero, according to an update filed with the SEC on Friday.

    His salary in 2019 had been $23,760. In 2018, it was $56,380.

    'However, he has never accepted his salary,' the company said. 'Commencing in May 2019 at Mr. Musk's request, we eliminated altogether the earning and accrual of this base salary.'

    Under his 2018 compensation agreement, Musk's total compensation package is stock-based. His options vest based on his ability to push the company to hit certain operating metrics.

    The 10-year agreement included 16 operational milestones. If Tesla hits 12 of those milestones, and the company's market cap hits $650 billion, Musk's shares will vest on schedule, according to the company.

    Tesla had hit six of those milestones as of Friday, the company said.

    The company's market cap surged past $650 billion in 2020. It was $704.81 billion as of Friday's close.

    In 2019, Musk paid cash for vested options that were valued at $30.5 million, but didn't sell any of the shares bought in that transaction, according to Friday's filing. The filing didn't list a vested-option purchase for 2020.

    Under the 2018 agreement, Musk's exercise price was $70.01 per share, SEC filings said. Tesla stock ended the week at $716.70 per share.

    'Only time I sell Tesla stock is when my stock options are expiring & I have no choice,' Musk said on Twitter in June.

    Bloomberg last week estimated Musk's total 2020 compensation to be $6.7 billion, the highest of any US chief executive.

    Musk has often said he's earmarked his Tesla stock to help humans reach Mars. When asked about his 2018 compensation plan in November, he said he 'didn't expect the stock to rise so much so soon.'

    'The reason for the stock options is that they're needed to help pay for humanity to get to Mars in 10 to 20 years,' he said on Twitter.
