The race for the “holy grail” of EV batteries is heating up. Mercedes-Benz is now testing EVs with solid-state batteries on the road, which could unlock over 600 miles of driving range.

Mercedes solid-state battery-powered EVs hit the road

Mercedes is working with US-based Factorial Energy to launch the new battery tech, promising more driving range, faster charging, and efficiency.

Last summer, Factorial delivered its first solid-state battery cells based on its propriety FEST (Factorial Electrolyte System Technology).

Mercedes and Factorial took it a step further, revealing the more advanced all-solid-state Solstice battery in September. The new batteries are being co-developed to power Mercedes’ next-gen electric models. With a sulfide-based solid electrolyte, the battery is safer and more efficient.

With a “breakthrough” energy density of 450 Wh/kg, Factorial said the new Solstice battery is expected to provide 80% more driving range than current lithium-ion batteries.

According to Autocar, Mercedes is already testing EVs with solid-state battery tech on the road. The tests are taking place in the UK using an EQS prototype equipped with the new batteries.

Although full specs have yet to be confirmed, Mercedes said the EQS’s 12-module battery housing was flexible enough for different configurations.

Mercedes expects the new battery to extend the driving range by about 25%. The current EQS 450+ rated with up to 511 WLTP miles range would suggest a driving range of over 620 miles.

Factorial aims to unlock over 600 miles of driving range with 40% weight savings compared to conventional Li-ion batteries. The company says Solstice is 33% smaller than a current 90 kWh battery at 580 lbs.

In December, Factorial announced a major milestone after its Solstice all-solid-state battery cells achieved 40 Ah capacity. The company is working with other major automakers, including Hyundai and Stellantis, to advance solid-state battery technology and aims to launch solid-state batteries by 2030.

According to Mercedes chief tech officer Markus Shafer, the new Solstice batteries will “set new standards in range, cost, and performance. ” Mercedes expects to be producing solid-state batteries at scale by the end of the decade.

Electrek’s Take

Mercedes is among several automakers and other companies developing solid-state batteries in hopes of unlocking more range, safety, and efficiency.

The news comes after local reports earlier this month suggested Hyundai will reveal its all-solid-state EV battery demo line in March. Japanese rival Honda unveiled its pilot line to the public in November.

Stellantis announced plans to launch a fleet of electric Dodge Chargers powered by Factorials solid-state batteries in 2026.

Hyundai, Honda, Toyota, Stellantis, and others aim to mass-produce solid-state batteries by the end of the decade.

And don’t forget that Chinese EV battery leaders BYD and CATL are also racing to launch solid-state batteries. Which company will come out on top?

NIU’s scooter-sized electric microcar is actually headed for production

NIU's scooter-sized electric microcar is actually headed for production

Earlier this year, we covered the unveiling of the NIUMM, an electric microcar designed for urban residents (and especially those with a NIU scooter already, since it shares the same batteries). Now the company is actually bringing it to market.

The electric microcar was on display at EICMA 2025, the Milan Motorcycle Show, where NIU showed off how it shares the same drivetrain as its NQi-series scooters.

The small format L6e quadricycle uses a pair of NQi batteries – the same ones from NIU’s scooters – to power the little not-a-car up to around 70 km (43 miles) at speeds of up to 45 km/h (28 mph). That’s the maximum allowable speed for the L6e class.

For anyone who already owns the scooter, those two batteries may be sufficient. But the range can be nearly doubled by carrying a second pair of batteries in the convenient extra battery slots built into the vehicle.

When the NIUMM was originally launched, it wasn’t yet clear if it was actually headed for production, or at least when that may be. But NIU’s Director of International, Sieghart Michielsen, explained that the vehicle is finishing homologation testing now, marking the last major obstacle to its commercial launch.

L6e quadricycles have carved out a unique and growing niche in European cities, where their compact size, low speed, and lightweight classification make them ideal for navigating dense urban environments. These light four-wheeled vehicles are limited to a top speed of 45 km/h (28 mph) and a maximum weight of 425 kg (excluding batteries), allowing them to be driven with a moped license in many countries.

That accessibility, combined with their affordability and electric drivetrains, has made L6e quadricycles especially popular among teenagers, city dwellers, and older adults looking for an easy-to-use alternative to cars.

One of the most iconic examples is the Citroen Ami, a no-frills, ultra-compact electric vehicle that has gained cult status in urban areas thanks to its minimalist design, €7,000 price tag, and availability through subscription or car-sharing services. My wife and I spent a week living with a Citroen Ami while on vacation in Greece, and it proved to be a fascinating way to navigate around.

Other standout L6e models like the Renault Twizy, the Microlino, and the Eli Zero, have helped demonstrate real demand for niche, small vehicles. These vehicles offer just enough comfort and protection from the elements for short city trips, while avoiding the cost, complexity, and parking headaches of full-size cars –making them an increasingly attractive option in Europe’s car-light future.

NIU could leverage the growing momentum for these types of vehicles if it can stick the landing with the NIUMM. While we still don’t have solid pricing or availability timelines yet, it looks like we’re looking at sooner rather than later.

All the EVs you can buy for less than Cadillac CELESTIQ’s $60,000 price hike

All the EVs you can buy for less than Cadillac CELESTIQ's ,000 price hike

Cadillac wants to live up to its “standard of the world” tag line so bad they can taste is – but adding $60K to the CELESTIQ’s MSRP might not be the flex the marketing team might think. To teach them a lesson, we’re going to ignore the CELESTIQ and list every new EV you can buy for less than that $60K price hike, instead. Enjoy!

Cadillac is on the verge of an electric renaissance, with nearly 40% of all new Caddies sold last quarter being electric and historic votes of confidence coming from the international motoring press. That said, a $60,000 price hike on the company’s hand built, ultra-luxury flagship CELESTIQ sedan feels especially like a cynical cash grab in today’s economy.

So, instead of talking about the now $60,000 pricier Cadillac CELESTIQ, I’ve decided to give you a list of all the new EVs you can buy (in the US, at least) for less than that $60K. Take a look at the list, below, then let me know if I missed any in the comments.

If you’re curious about what those vehicles are actually selling for, what rebates and special rates are out there, or even just want to take one for a test drive, click on one of the links and you’ll be directed to a local dealer who can walk you through it all (trusted affiliate link).

Nissan has global ambitions for its affordable plug-in pickup truck [update]

Nissan has global ambitions for its affordable plug-in pickup truck [update]

Zhengzhou Nissan has launched a new, plug-in pickup in the Chinese market called the Z9. It’s the same size as the Nissan Frontier Pro, offers over 35 miles of all-electric range, and pricing starts at just $16,600.

UPDATE 04NOV2025: more details and more markets for 2026.

The rebuilding of Nissan started to pick up earlier this year with the launch of the brand’s first plug-in pickup truck in China this past summer. The plug-in hybrid (PHEV) model offers 410 hp and an 84 mile electric-only range – more than enough for it to meet the everyday needs of most drivers with easy access to liquid fuel when needed.

It seems like a neat truck, but since it was designed and developed specifically for the Chinese market, its great specs and nearly impossible $24,800 starting price (on the entry-level Frontier Pro model) meant it would have limited impact – and limited interest – in other markets.

Until now, that is! CarScoops is reporting that Nissan now has plans to export a tweaked version of the hybrid Frontier to international markets, and speculates that, “a different version of it could well be built in the US, [since] Nissan’s CEO recently confirmed that a hybrid Frontier is in the works for the North American market.”

You can read the original post, first published back in June, below, then let us know what you think of Nissan’s plans to export its plug-in pickup to other markets in the comments.


Positioned as the electrified sibling of the domestically-built Nissan Frontier Pro, the Zhengzhou Nissan Z9 is essentially a Chinese-market version the Frontier Pro, and it’s spec’ed and priced accordingly, with the as-yet undisclosed price of the Frontier Pro expected to come in a bit higher than the Z9.

That’s less interesting. What’s more interesting is that the Z9 offers 35 miles (60 km) of range on the base, 17 kWh battery, at a price that significantly undercuts even the Slate EV’s $28,000 pre-$7,500 incentive price tag – and that incentive is far from a sure thing.

What’s more, if you feel like spending a bit more, you can get a Zhengzhou Nissan Z9 equipped with a 32.85 kWh battery that’s good for almost 85 miles (135 km) of all-electric range. And even that extended-range model, at ¥168,900 (about $23,400) is still price-competitive with the Jeff Bezos-backed Slate EV.

In short, it’s bound to be a winner.

It’ll sell, but it won’t sell here

With excitement surrounding the Kia Tasman, Slate, and other, similarly affordable light-duty pickups building on the success of the Ford Maverick hybrid, it should come as no surprise that Nissan has international ambitions for its newest electrified pickup.

“In alignment with our ‘In China, For China, Toward the World’ strategy for electrification and smart transformation, Nissan will fully support ZNA’s ‘off-road strategy,’” explained Stephen Ma, Chairman of Nissan (China) Management Committee and President of Dongfeng Motor Co., Ltd. “We are working to strengthen our research and manufacturing capabilities, further advancing our presence in the core markets of pickups and off-road vehicles, with the ultimate goal of achieving global expansion.”

It’s exciting stuff, but with all the recent troubles it’s been experiencing, it’s doubtful that Nissan will bring either of its new, Chinese-built mid-size pickups to the US (electrified or otherwise).

“The mission of the new generation of Chinese automotive professionals is clear – to ensure that made-in-China cars are driven across the world. ZNA will utilize its dual-brand and dual-channel advantages to expand its global footprint,” Mr. Mao Limin, Executive Vice President of ZNA, at the Z9’s launch. “We aim to be one of the top exporters of pickups within three years and to reach a sales milestone of 100,000 units.”

That said, Nissan Hardbody fans shouldn’t lose hope quite yet. If Nissan is able to find a new savior in Toyota, a Taco-based BEV pickup with a new LEAF/Ariya-type front fascia might make more sense than you think.

Electrek’s Take

I’ve already written out my own comeback plans for Nissan, and this new Chinese-market pickup truck doesn’t really fit into them. Like many of you, I’m of the belief that a PHEV isn’t an EV – but I do see their value as “lilypad” cars, and the two Lightning owners I know? Their previous Ford F-150s were hybrids.
