In the latest news released as part of its impact report, Tesla claims that its battery packs lose only about 10% of their energy capacity after 200,000 miles.

Battery degradation, which represents the loss in capacity and range over time with increasing mileage, is one of the biggest concerns of new electric vehicle buyers.

It’s also an important part of the equation to make electric cars more sustainable.

The longer a battery pack can be in operation, the longer it will keep itself from being scrapped for recycling and the longer it can keep the whole car in operation.

Tesla has sporadically released some data about its battery degradation over the years.

This year, it updated stats from its Model S and Model X fleet, and it claims a battery capacity retention of roughly 90% after 200,000 miles:

The data also confirms real-world reports that the degradation is steeper for the first 100,000 miles and then it slows down and stabilizes for the next 100,000 miles.

Tesla believes that 200,000 miles is when its vehicles get scrapped on average:

“Tesla’s battery packs are designed to outlast the vehicle. We estimate that a vehicle gets scrapped after approximately 200,000 miles of usage in the U.S. and roughly 150,000 miles in Europe.”

The data is only for Model S and Model X, which have been around for longer, but Tesla claims that the Model 3 battery packs are made to last 500,000 miles and the automaker aims for its next generation of batteries to last 1 million miles.

Not all packs are created equal

For Model S and Model X, Tesla has had quite a few different battery packs over the years and there are not all as good to retain energy capacity.

Last year, we reported on a leak of data that enabled us to get a very precise look at the difference between Tesla’s 90 kWh and 85 kWh pack.

It showed that the 90 kWh would lose battery capacity much faster than the 85 kWh pack:

Each point on this chart represents a Model S or Model X in Tesla’s customer fleet at the end of 2017. We have tens of thousands of data points directly from Tesla, which is arguably the best data ever released about Tesla battery degradation.

The ‘Y’ axis represents the current usable battery capacity of the car in kWh pulled from Tesla’s own battery management system and the ‘X’ axis is the total use of the battery pack in kWh since the vehicle was new.

It shows that the 90 kWh battery pack (green) starts at ~85 kWh of usable capacity and drops on average by about 6 kWh after 20,000 kWh or 235 cycles, which should represent over 60,000 miles.

As fo the 85 kWh battery pack, it starts with a usable capacity of about 80.5 kWh and it drops on average to about 77 kWh after 20,000 kWh.

It means that for the first few years of use, the 90 kWh battery pack degrades almost twice as fast as the older 85 kWh battery pack.

The good news is that the steeper degradation in the 90 kWh battery packs also appears to temper off over time and mileage.

A Tesla Model X with over 400,000 miles

As some of you may know, I have experience with high-mileage electric cars, especially high-mileage Tesla vehicles.

Last year, I bought one of the cheapest and most high-mileage Tesla Model X vehicles ever.

With over 400,000 miles (650,000 km), it’s one of the highest-mileage electric vehicles in the world and serves as a great case study for the longevity of electric cars, in general, and Tesla vehicles in particular.

We previously reported on battery degradation on the extremely high-mileage vehicle.

It’s a Model X 90D, which when new had an EPA rating of 257 miles (414 km).

Today, it gets about 230 miles (370 km) on a full charge, which means a 10.5% degradation in battery capacity.

However, this Model X got a battery replacement under warranty at 317,000 miles. That’s more than half a million kilometers. 

Interestingly, the original battery pack wasn’t replaced due to battery degradation but because of an even greater problem with the pack.

Once the state-of-charge would reach around 40%, which normally would mean just over 90 miles of range, the capacity would quickly drop to 0.

Tesla replaced the battery pack under warranty. It’s quite impressive that it lasted for over 300,000 miles before failing.

Now the second battery pack on this Model X has almost 100,000 miles (160,000 km) on it and as previously mentioned, it is seeing a roughly 10% battery degradation.

Stars of sumo head to London’s Royal Albert Hall – and noodles sell out

Stars of sumo head to London's Royal Albert Hall - and noodles sell out

They’re getting through 70kg of rice a day and the wholesaler has run out of noodles. Yes, Sumo returns to London on Wednesday.

It’s just the second time a Grand Tournament has been held outside of Japan – and this is a sport that has records going back more than 1,500 years.

It’s 34 years since the Royal Albert Hall hosted the only previous such event on foreign soil – and the appetite for tickets meant all five days sold out immediately.

Much of the focus is on the two grand champions or yokozuna, the 74th and 75th men to attain the rank.

They’re the Mongolian Hoshoryu Tomokatsu, plus Japan’s Onosato Daiki – who this year became the quickest wrestler to achieve the rank in the modern era.

“I’m happy that Sumo is back after so many years,” Onosato said. “I hope I can show the UK fans how fantastic Sumo is.”

“Being a yokozuna has a lot of responsibility,” Hoshoryu told Sky Sports. “We have to show everyone an example of what a yokozuna is – and that’s very difficult.

“My uncle was a yokozuna – and I’m happy to follow in his footsteps. But I came here to London as a yokozuna which he didn’t, so I’m even happier.”

The two are already great rivals.

At the recent Aki Basho – the most prestigious tournament on the sumo calendar – the pair finished with identical records after 15 days of bouts.

It all came down to a final play-off between the two yokozuna – the first time that had happened in 16 years. It was Onosato who came out on top on that occasion.

Hoshoryu says he is a big fan of basketball and football. He follows Chelsea, although his favourite players are going back a bit: “Didier Drogba and Petr Cech. He’s the ‘keeper. I like this guy!”

Early starts and a hearty stew: The life of a rikishi

The wrestlers – or rikishi – have a rigorous training regime.

They live in communal blocks called stables and practice starts early. Perhaps surprisingly, everyone skips breakfast. After training and practice – and for the younger rikishi, chores – the wrestlers all eat together.

The staple of their diet is chankonabe, a hearty stew packed with meat and vegetables. The feeding of the 40 rikishi who have come over for the five-day tournament is a challenge in itself.

Donagh Collins, the CEO of co-organisers Askonas Holt, said: “We are going through 70 kilos of rice a day. Somebody told me that the wholesaler for the noodles has run out of noodles. We’re really pushing the system here.”

The ring – or dohyo – is just 4.55m in diameter and quite small when two giant wrestlers leap at each other.

The aim of the fights is to either get your opponent onto the floor – or, more spectacularly, shove or hurl them out of the dohyo, so spectators in the ringside seats may be getting extremely up-close to the wrestlers.

The last time the tournament was in Britain, the massive Konishiki, known as the Dump Truck, took centre stage.

The giant Hawaiian was the heaviest-ever rikishi coming in at 287kg – or 45 stone. That’s a lot of wrestler to dodge if he comes falling out of the ring towards you.

The Royal Albert Hall may be firstly a concert venue, but it has hosted the likes of John McEnroe, Lennox Lewis and even Muhammad Ali.

And for the next five days, the cream of the world of sumo will be thrilling the crowds – provided a new noodle supplier is found.

What is a yokozuna?

Yokozuna is the highest rank in sumo, with its name meaning “horizontal rope” and refers to the rope worn around a competitor’s waist as they enter the ring.

Grammy-winning R&B and soul star D'Angelo dies after 'prolonged battle with cancer'

Grammy-award winning R&B and soul singer D’Angelo has died following a battle with pancreatic cancer, his family has said.

He died on Tuesday, leaving behind a “legacy of extraordinarily moving music” following a “prolonged and courageous battle with cancer,” his family said in a statement.

The prominent musician, born Michael D’Angelo Archer, was 51 years old.

A family statement said: “We are saddened that he can only leave dear memories with his family, but we are eternally grateful for the legacy of extraordinarily moving music he leaves behind.

“We ask that you respect our privacy during this difficult time, but invite you all join us in mourning his passing while also celebrating the gift of song that he has left for the world.”

The singer rose to prominence in the 1990s with his first album, Brown Sugar.

The track “Lady” from that album reached No. 10 in March 1996 and remained on Billboard’s Hot 100 chart for 20 weeks.

Eurovision emergency vote on Israel's inclusion is called off

An emergency vote on Israel’s participation in the Eurovision Song Contest has been called off following developments in the Middle East, the European Broadcasting Union (EBU) has said.

Contest organisers had scheduled “an extraordinary meeting of [its] general assembly to be held online” in early November after several countries said they would no longer take part in Eurovision if Israel participated.

The EBU said in a statement that following “recent developments in the Middle East” the executive board had agreed on Monday that there should be an in-person discussion among members “on the issue of participation in the Eurovision Song Contest 2026”.

It said the matter had now been added to the agenda of its winter general assembly, which will take place in December.

Further details about the session would be shared with EBU members in the coming weeks, it added.

It is not clear if a vote will still take place at a later date.

Austria is hosting next year’s show in Vienna. The country’s national broadcaster, ORF, told Reuters news agency it welcomed the EBU’s decision.

Sky News has contacted Israeli broadcaster KAN for comment.

Will Eurovision boycott Israel?

Faced with controversy over the conflict in Gaza, Eurovision – which labels itself a non-political event – had said member countries would vote on whether Israel should or shouldn’t take part.

Slovenia and broadcasters from Spain, the Netherlands, Ireland and Iceland had all issued statements saying if Israel was allowed to enter, they’d consider boycotting the contest.

As one of the “Big Five” backers of Eurovision, Spain’s decision to leave the competition would have a significant financial impact on the event – which is the world’s largest live singing competition.

In September, a letter from EBU president Delphine Ernotte Cunci, said “given that the union has never faced a divisive situation like this before” the board agreed it “merited a broader democratic basis for a decision”.

On Monday, Palestinian militant group Hamas freed the last living Israeli hostages from Gaza, and Israel released busloads of Palestinian detainees, under a ceasefire deal aimed at bringing an end to the two-year war in the Middle East.

The war began when Hamas stormed into Israel on October 7 2023, killing around 1,200 people and taking 251 hostage.

Israel invaded Gaza in retaliation, with airstrikes and ground assaults devastating much of the enclave and killing more than 67,000, according to the Hamas-run health ministry.

Its figures do not differentiate between civilians and combatants but it says around half of those killed were women and children.
