Toyota is doubling down on the “holy grail” of EV tech — all-solid-state batteries. Its first EV could arrive as soon as 2027, promising longer driving range, faster charging times, and more.
Toyota to launch its first all-solid-state battery EV in 2027
After announcing a new partnership with Sumitomo Metal Mining Co. to mass produce cathode materials for the new battery tech on Wednesday, Toyota said it aims “to achieve the world’s first practical use of all-solid-state batteries in BEVs.”
Toyota said that its new batteries could significantly enhance driving range, charging times, and output, potentially transforming the future of automobiles.
Compared to current liquid-based batteries, which use electrolyte solutions, Toyota’s all-solid-state batteries utilize a cathode, an anode, and a solid electrolyte. According to Toyota, the next-gen battery tech “offers the potential for smaller size, higher output, and longer life.”

Toyota aims to launch its first all-solid-state battery-powered EV in 2027 or 2028. The new development agreement moves it one step closer to bringing the new battery tech to market on a mass scale.
The two companies have been developing cathode materials for all-solid-state EV batteries since 2021, focusing on some of the biggest challenges in producing them at a mass scale.
Using Sumitomo Metal Mining’s proprietary powder synthesis technology, Toyota claimed to have developed a “highly durable cathode material” for all-solid-state batteries.

Sumitomo has been supplying cathode materials for electric vehicles for years, but it’s now working to introduce the newly developed tech, moving it toward mass production.
The new agreement comes after Toyota was granted a METI certification to manufacture the new batteries in Japan last September.

Toyota is collaborating with several partners in Japan, including oil giant Idemitsu Kosan, to introduce the new EV batteries to the market.
Idemitsu announced plans earlier this year to build a large-scale production plant for lithium sulfide, a raw material used in all-solid-state EV batteries. Once up and running, the plant will be capable of producing 1,000 metric tons of lithium sulfide annually. The company is also aiming to mass-produce all-solid-state batteries in 2027.

The new batteries are part of Japan’s plans to secure a domestic supply chain and reduce its reliance on China and South Korea. Toyota is among several companies in Japan that are investing a combined $7 billion (1 trillion yen) in domestic battery production.
Electrek’s Take
Will Toyota be the “world’s first” to put all-solid-state EV batteries to practical use? Others, including Mercedes-Benz, BMW, Volkswagen, and Honda, are also betting on the new technology.
Mercedes claimed to have put “the first car powered by a lithium-metal solid-state battery on the road” in February. Just last month, Mercedes drove an EQS, equipped with solid-state batteries, for nearly 750 miles (1,205 km).
Mercedes’ tech boss, Markus Schäfer, is already calling the new EV battery tech a “gamechanger” for electric vehicles. The company aims to bring solid-state batteries into series production by the end of the decade.
Meanwhile, CATL and BYD, which are already dominating the global battery market, aim to introduce the new battery tech around 2027.
SAIC MG launched the new MG4 in August, deeming it “the world’s first mass-produced semi-solid-state” electric vehicle.
Can Toyota compete? It has been promising to launch all-solid-state batteries for years now, but new alliances could help make it a reality. As for the “world’s first,” however, that may be a stretch.

NextEra Energy is partnering with Exxon Mobil, the country’s largest oil company, to build a large data center site powered by natural gas for a potential tech customer, CEO John Ketchum told investors Monday
The 1.2 gigawatt power plant would combine gas generation with Exxon’s carbon capture technology to reduce emissions, according to NextEra’s presentation to investors.
They plan to market the site to a hyperscaler in the first quarter of 2026. Hyperscalers are the big tech companies that are building data centers to train and run artificial intelligence applications. There is no signed agreement with a hyperscaler yet.
NextEra and Exxon have secured 2,500 acres of land for the facility. The site will be located in the Southeast in close proximity to Exxon’s carbon-dioxide pipeline infrastructure, according to NextEra.
NextEra is the largest renewable energy developer in the U.S., but it is leaning into natural gas to meet the growing demand from data centers. The power company plans to bring as much as eight gigawatts of gas generation online by 2032, and is developing a pipeline of 20 gigwatts of gas generation.
NextEra plans to build 15 gigawatts of power for data center hubs by 2035, Ketchum said. That includes at least three data center campuses that NextEra is developing with Alphabet‘s Google.
“A lot of those will get started with what I call bridge power — renewables, storage,” the CEO said. “We’re also at that same time planning for the gas to come behind it.”
The tech sector has primarily secured renewables and increasingly nuclear power to supply data centers in an effort to meet its climate targets.
Mercedes calls it the “one-liter” car for a reason. The new Mercedes CLA EV has an impressive EPA range of 374 miles, but in real-world driving, it can go even further.
Mercedes CLA EV beats EPA range in real-world driving
The new CLA EV might just be the most critical Mercedes model yet. It’s the first of the luxury brand’s latest generation of electric vehicles, promising to be much more advanced, efficient, and refined than ever before.
Powered by an 85 kWh battery pack, the 2026 Mercedes-Benz CLA 250+ has an EPA-estimated range of 374 miles.
Although that’s already among the highest for any 2026 model-year EV in the US, the electric CLA can drive even further in the real world.

The folks at Edmunds just got their hands on one to test it out. In the Edmunds EV Range Test, the 2026 Mercedes CLA EV crushed its EPA figures, driving an impressive 434 miles on a single charge, beating its official ratings by 16%.

Out of 13 Mercedes models Edmunds has tested, the new CLA EV had the second-longest driving range, trailing only the EQS 450+. However, given that the EQS is a full-size sedan and significantly more expensive than the CLA, it’s expected.
The 2026 Tesla Model 3 Standard went 339 miles, while the 2026 Audi A6 E-tron drove 402 miles during the EV Range Test.

The Edmunds EV Range Test is 60% city and 40% highway driving with an average speed of 40 mph. Each vehicle is set to the most efficient drive setting, while the climate control is set to 72 degrees to reflect the most accurate real-world driving conditions drivers encounter each day.
During the test, the electric CLA used 23.2 kWh per 100 miles of driving, beating the EPA’s estimates by 16.5%.
On the Edmunds EV Charging Test, it had an average charge rate of 193 kW from 10% to 80%, earning a score of 833 miles per hour. That’s the second-best of those tested, behind the Hyundai IONIQ 6.

The new Mercedes CLA EV is now the least expensive car they’ve tested, with over 400 miles of range. Last week, Mercedes launched the 2026 CLA 250+ EV, starting at $47,250.
Mercedes said it will begin delivering the first customer models this month, with output ramping up throughout early 2026.
Tesla is pulling every demand lever available as we head into the final weeks of the year. The automaker has launched a new set of aggressive incentives in the US, including free upgrades on inventory vehicles, 0% APR financing, and $0 down leases.
It’s the end of the quarter (and year), and as per usual, Tesla is trying to empty its inventory, but it’s more difficult this year due to the end of the tax credit in Q3 pulling a lot of demand away from Q4.
We have regularly reported on Tesla ramping up incentives at the end of the year, but this new batch is arguably the most aggressive we have seen in a long time.
First off, Tesla is offering one free upgrade on eligible inventory vehicles.

If you go to Tesla’s inventory page for Model 3 or Model Y, you will see a lot of vehicles listed with a “Free Upgrade” tag. This basically means that if you pick a car that has a paid option, like a premium paint color (Ultra Red or Quicksilver), 20″ Induction wheels, or the White interior, Tesla is waiving the cost of that option.
That’s a value of anywhere from $1,000 to $2,500 depending on the option.
On top of that, Tesla has expanded its financing offers. The company is now offering 0% APR financing for up to 72 months on Model 3 and Model Y purchases.
This is a significant move. We have seen low interest rates before, but 0% for 72 months is basically free money, especially in the current interest rate environment.
But wait, there’s more.
For those looking to lease, Tesla has introduced $0 down leases for the Model Y.
Previously, Tesla required a down payment of at least $3,000 for its best lease rates. Now, you can drive off the lot with a Model Y for $0 down, though the monthly payments will obviously be higher than with a down payment.
Tesla writes on its website regarding the new push:
“Take delivery by December 31, 2025 to take advantage of these limited-time offers. Available on select inventory vehicles while supplies last.”
The automaker is clearly trying to deliver as many cars as possible before the ball drops on 2025.
Electrek’s Take
The end-of-year push is in full swing.
When you see Tesla stacking incentives like this, 0% financing, zero down, and free options, it tells you one thing: they have inventory to move.
With a lot of demand in the US pulled forward into Q3 due to the end of the tax credit for electric vehicles, it was always clear that Tesla would have trouble moving cars in Q4.
These are roughly the best end-of-quarter incentives we have ever seen, and even then, I’d be surprised if Tesla can come close to its record deliveries of last year’s Q4: 495,000 vehicles.
