Elon Musk has confirmed Tesla Semi’s efficiency at 1.7 kWh per mile, which means it has a roughly 900 kWh battery pack. It’s an important piece of information, but there are still more questions to answer before Tesla Semi can officially be a truly disruptive product.

Yesterday, Tesla unveiled the production version of its Tesla Semi class 8 electric truck and delivered the first units.

At the event, Tesla described an electric truck that could truly disrupt the trucking industry.

However, we noted that there were a few pieces of information that Tesla omitted from the event that could really be major difference makers.

The two main ones are the weight of the actual truck and its price:

After digesting yesterday’s Tesla Semi presentation, Tesla has potentially a massively disrupting product on its hands, but it omitted two things that need to be confirmed to make it official: weight of the tractor and its price. I wish I could ask Tesla or Elon about it…

The trucking industry is all about the economics of moving products by the pound. The main thing that will drive that is the cost of operation per mile, which is mainly affected by the vehicle’s efficiency.

Tesla has already reported an efficiency under 2 kWh per mile which is impressive, but not exactly clear when you are trying to determine your cost per mile for electricity.

On Twitter last night, Tesla CEO Elon Musk confirmed that it is 1.7 kWh per mile. That’s more precise, and truck operators can input their electricity rates to get an idea of fuel costs and savings compared to diesel.

It also gives us an idea of the Tesla Semi’s battery pack. It’s not perfect since we don’t have the exact range of the truck. At 500 miles, which Tesla claims, that’s 850 kWh, but the pack generally has a buffer, and based on the 500-mile trip it completed, it looks like the electric truck might have some more in it.

Now what we need to know is how much cargo can a Tesla Semi carry. A class 8 truck fully loaded needs to weigh 80,000 pounds or less as per regulations, but electric trucks have been allowed an extra 2,000 pounds.

In order to know that, we need to know the weight of the truck itself. You have to deduct the weight of the trailer, which is about 10,000 pounds for a 53-foot trailer, and the weight of the truck from the 82,000-pound limit.

Tesla says that it will roughly have the same capacity as a diesel truck, but diesel tractors have a wide range of weight from roughly 12,000 to 25,000 pounds. The Tesla Semi’s power would certainly need to be compared more to the higher end of that range, but at the end of the day, trucking companies want as much cargo capacity as possible.

The automaker hasn’t confirmed the weight of the Tesla Semi, but we can deduce from its load test with concrete blocks that it is around 27,000 pounds, but that’s unconfirmed at this point.

That’s not the best, but it would still give the Tesla Semi the capacity to move about 45,000 pounds of cargo, which still makes the vehicle super useful. Also, it is safe to assume that the number will improve greatly over the years as battery technology improves.

But nonetheless, it would be useful if Tesla could confirm the weight of the Tesla Semi.

Then we need the actual price of the truck. In 2017, Tesla said the trucks would be $150,000, $180,000, and $200,000, depending on the model, but those prices are expected to have changed over the last five years.

Those prices with that capacity would make the Tesla Semi revolutionary since it would pay itself back in about three years just from fuel savings in most markets, but we don’t know that for a fact without the official price.

Electrek’s Take

This is pretty wild. We are super close to being able to confirm that the Tesla Semi can change the entire paradigm of the trucking industry, but Tesla just needs to release a few more pieces of information to make it happen.

The fact that Tesla doesn’t let the press into its events and only superfans is really a bad look for the company at this point. Yes, the press can be annoying, even malicious in some cases, and I don’t say they should let those people in, but there are also plenty of people whose goal is just to keep their readers as best informed as possible, and they would ask important questions at those events that need answering – questions that a lot of fans don’t bother asking. Everything Musk says is good enough for them.

I can’t ask any of those questions because Tesla doesn’t have a PR department, and the only official comments you can get these days are from Musk on Twitter, where he blocks me and surrounds himself with sycophants:

This is basically confirmed now. Here’s the chronology:

1- Elon announced a wave spam accounts being banned.

2- Several of his top supporters get banned because they are indistinguishable from bots by the algo.

3- Elon personally looks into it and reinstate the accounts. https://t.co/aCjnSgmNnt

— Fred Lambert (@FredericLambert) December 1, 2022

This is just not how a company that aims to be transparent should operate. And obviously, I’m not talking about trade secrets here.

Anyway, the rant is over. I hope Tesla is going to release that information soon, and if it is on the right side, I’ll be the first to celebrate Tesla revolutionizing the trucking industry.

Why a landmark ruling from the world’s top court puts financial markets on notice

Why a landmark ruling from the world’s top court puts financial markets on notice

Vanuatu’s Climate Change Minister Ralph Regenvanu (C) delivers a speech as he attends a demonstration ahead of the International Court of Justice (ICJ) session tasked with issuing the first Advisory Opinion (AO) on States’ legal obligations to address climate change, in The Hague on July 23, 2025.

Gripped by corporate earnings season and U.S. President Donald Trump‘s back-and-forth tariff policy, investors largely shrugged off a historic climate ruling from the world’s top court.

But for some, the International Court of Justice’s (ICJ) recent advisory opinion on state’s legal obligations in the face of climate change could emerge as a watershed moment for financial markets.

Günther Thallinger, a board member at Allianz, one of the world’s biggest insurers, said that close watchers of the ICJ’s July 23 ruling described it as perhaps the most significant climate development since the 2015 Paris Agreement.

At the time, the pronouncement marked the ICJ’s first-ever opinion on climate change and laid out that climate action is not optional.

The court said in a unanimous ruling that governments and countries have a legal obligation to protect the environment from greenhouse gas emissions, protect present and future generations from the climate crisis and to cooperate internationally.

Notably, the ICJ also found that fossil fuel production, including licensing and subsidies, “may constitute an internationally wrongful act which is attributable to that State.”

This opinion for investors, for capital market participants, really means something.

The ruling, which was the brainchild of young law students in low-lying Pacific island states and championed by the government of Vanuatu, is widely expected to have far-reaching legal and political consequences.

Speaking in a personal capacity, Thallinger said that while the ICJ’s opinion is based on existing law and conventions, the ruling could yet have meaningful ramifications for a vast range of assets — whether one cares about climate change or not.

“If one takes as an investor what the International Court of Justice just said, then a revaluation of these assets needs to happen. Every prudent investor must do this now,” Thallinger told CNBC by video call.

“Even if they don’t like the discussion around climate change, even if they would say they denigrate the Court of Justice completely, they must expect that, in some countries, some governments, some courts are going to follow this opinion,” Thallinger said.

“If they follow this opinion, it has asset valuation implications, quite clearly. So, this opinion for investors, for capital market participants, really means something.”

Licensing and subsidies

On the issue of licensing and subsidies, Thallinger said the ICJ’s ruling could prove to be a significant development.

That’s because licensing and permitting for the mining sector, for example, and government subsidies for fossil fuels could be at risk following the court opinion. The burning of fossil fuels such as coal, oil and gas is the chief driver of the climate crisis.

“If subsides are unlawful, then one should expect that subsidies are somehow stopped at a certain point in time,” Thallinger said.

“Now, certain business processes live on these subsidies or at least benefit to a certain degree on these subsidies. And, as always for an investor, usually you look simply at the cashflow, and if the cashflow part is missing or all of a sudden becomes much smaller then that means another valuation,” he added.

The U.S. and China, the world’s two biggest carbon emitters, provided a mixed response to the ICJ’s ruling.

“As always, President Trump and the entire administration is committed to putting America first and prioritizing the interests of everyday Americans,” White House spokeswoman Taylor Rogers said in response to the court opinion, Reuters reported.

A spokesperson for China’s Foreign Ministry, meanwhile, said the ruling has a “positive significance” for advancing international climate cooperation and sought to reaffirm the Asian country’s status as a developing country.

Mixed signals

Not everyone is as concerned about the ICJ’s ruling from an investor standpoint.

“I feel like the wide spectrum of views that exist in the investor community on climate change, and the action that investors are supposed to take, will probably mean that the decision is a bit of a Rorschach test,” Lindsey Stewart, director of institutional insights for Morningstar, told CNBC by video call.

“People are just going to see things that kind of confirm their existing view,” he added.

A Rorschach test refers to a psychological assessment during which a person is asked to describe what they see in a series of inkblots.

Ida Kassa Johannesen, head of commercial ESG at Saxo Bank, said the ICJ’s intervention is a non-binding advisory opinion, rather than a ruling, “and this distinction is crucial.”

Companies with significant environmental footprints, such as those in the oil and gas, mining and heavy industry sectors, are likely to face increased litigation risk, which could affect their costs, valuation and reputation, Johannesen told CNBC by email.

“As a result, investors and particular large institutional investors may begin to reallocate capital away from high-risk sectors to manage exposure to climate-related legal and reputational risks,” she added.

Saxo Bank’s Johannesen pointed out that the U.S. and China both expressed reservations about the ICJ’s opinion, emphasizing its non-binding nature and calling for flexibility in climate action.

The Trump administration also recently signed into law the U.S. president’s One Big Beautiful Bill Act, a package that is favorable to mining and oil and gas companies.

“All this sends mixed signals which would probably lead to fragmented market responses between the world’s 2 largest economies and the [rest of the world], slow down global regulatory convergence and ultimately limit the (short-term) impact on markets and investor behavior,” Johannesen said.

A spokesperson at ABP, one of Europe’s largest pension funds, welcomed what they billed as “the spirit” of the court’s opinion, but said they do not anticipate any short-term ramifications for financial markets.

“The ICJ’s advisory opinion sends a signal that climate inaction may constitute a breach of international law. However, given its non-binding nature, we don’t expect immediate changes in national policies or financial markets,” an ABP spokesperson told CNBC by email.

The Dutch pension fund, which doesn’t invest in fossil fuels and says it actively supports climate solutions, highlighted that Europe, for example, already has a lot of climate legislation in place.

Global EV sales hit 10.7M in 2025 – Europe surges, US stalls

Global EV sales hit 10.7M in 2025 – Europe surges, US stalls

Global EV sales are still riding high, with 1.6 million EVs sold in July 2025, according to new data from global research firm Rho Motion. That’s up 21% from July last year, even though sales dipped 9% from June. It brings total EV sales for the first seven months of the year to 10.7 million – up 27% compared to the same period in 2024.

China stays on top

China continues to dominate, with 6.5 million EVs sold year-to-date, accounting for over half of all global EV sales. BEVs are still the top choice, with sales up 40% this year. Plug-in hybrids (PHEVs) didn’t fare as well, with domestic sales down 15% month-over-month and 10% year-over-year.

Even though Chinese EV sales dropped 13% in July from June, EVs made up over 50% of all passenger car sales for the third month in a row. The government is helping keep momentum going with another round of Q3 funding for its EV trade-in scheme, and a final 2025 round is expected in October.

Europe’s EV momentum is speeding up

Europe saw a 30% year-to-date jump in EV sales, reaching 2.3 million units. Germany and the UK are leading the pack – Germany’s up 43%, and the UK is up 32%. But France posted just a 9% year-over-year gain in July and is still down 11% for the year.

To help turn things around, France is revamping its EV leasing program for low-income households starting September 30, aiming to support more than 50,000 purchases.

Meanwhile, Italy is the dark horse of 2025. Thanks to fresh incentives totaling around $700 million, EV sales are up 40%, and the country is quickly catching up to its neighbors. EV market share in Italy now stands at 11%, compared to 27% in Germany and over 30% in the UK.

North America stalls out except for one short-term boost

North America is lagging, with just a 2% bump in EV sales year-to-date. In the US, that’s partly due to policy uncertainty and tariffs. Automakers took a multi-billion-dollar hit in Q2, although some of that was offset by reduced requirements to buy zero-emission vehicle credits.

A spike in demand is expected in Q3, as buyers rush to take advantage of the Inflation Reduction Act’s EV tax credit before it expires on September 30, but a cooldown is then anticipated.

Some automakers are shifting their EV strategies: Ford recently announced a new “Universal EV Platform” and plans to launch a $30,000 midsize electric pickup with lithium iron phosphate (LFP) batteries by 2027.

And on the trade front, the US has inked deals with South Korea, Japan, and the EU to impose a 15% tariff on imported cars.

The bottom line

Global EV sales are still charging ahead, even if the road is bumpy in some regions. China’s holding steady, Europe’s revving up, and North America’s waiting to see what happens next. Rho Motion data manager Charles Lester said, “Despite regional variations, the overall trajectory for EV adoption in 2025 remains strongly upward.”

Volkswagen is making some EV owners pay extra to unlock full potential

Volkswagen is making some EV owners pay extra to unlock full potential

Another monthly subscription? Some Volkswagen EV drivers will now need to pay extra to unlock their vehicle’s full potential.

Volkswagen has put performance behind a paywall, at least for ID.3 drivers in the UK. The Volkswagen ID.3 Pro and Pro S are now listed with 201 hp on the UK website.

To unlock the vehicle’s full performance of 228 hp, drivers will now need to pay extra. You can choose from a monthly subscription, starting at £16.50 ($22) per month, or you can opt for a one-time lifetime fee of £649 ($880).

However, the one-time fee is attached to the vehicle, not the buyer. So if it’s sold, the upgrade goes with it. As Auto Express pointed out, the monthly payment is nearly three times that of a standard Netflix membership.

Although the performance upgrade locks the extra power behind a paywall, Volkswagen said it doesn’t affect range.

Volkswagen isn’t the first, and likely not the last, to make drivers pay for their vehicles’ full potential. Remember when BMW tried to charge $18 a month for heated seats and other features in 2022?

Yeah, that didn’t go over so well. BMW has since dropped the subscription. Other brands, including Polestar, offer similar performance upgrades.

Will Volkswagen try to charge EV drivers in the US or other parts of Europe extra for performance? Given the backlash from BMW, it’s not likely. We’ll see how it goes over in the UK first.

The company is gearing up to launch a new series of entry-level EVs, starting with the ID.2 next year. An SUV version of the ID.2 is scheduled to launch shortly after, followed by the production version of the ID.1, which is set to arrive in 2027. Volkswagen is also considering a “mini Buzz” that could replace the Touran, but nothing has been confirmed.
