The first BMW EVs powered by all-solid-state batteries are now on the road for testing. BMW used an i7 to test the “holy grail” of EV battery tech, promising longer driving range at a lower cost.
BMW tests first EVs with all-solid-state batteries
BMW hit a milestone on Monday after completing its first on-road tests using Solid Power’s all-solid-state battery (ASSB) cells.
Often called the “holy grail” of EV battery technology, ASSBs promise significantly higher energy density than current batteries. Since they can pack higher energy density into a smaller space, all-solid-state batteries have the potential to boost driving range at a lower cost.
The i7 test vehicle is based on BMW’s current Gen 5 architecture, using new prismatic cells in modules. To integrate Solid Power’s ASSB cells, BMW modified the platform using new module concepts.

BMW and Solid Power have been working together since 2022 to advance the new EV battery tech. In December 2022, BMW revealed plans to license Solid Power’s tech for a new solid cell prototype line at its Cell Manufacturing Competence Center (CMCC) in Parsdorf.

BMW follows Mercedes-Benz, which announced in February it had put “the first car powered by a lithium-metal solid-state battery on the road” through its partnership with US-based Factorial Energy.
Mercedes used a modified EQS, fitted with solid-state batteries. With an expected 40% weight savings compared to current Li-ion batteries, Factorial aims to unlock over 600 miles of driving range.

The milestone also comes after Martin Schuster, BMW Group’s vice president of next-generation battery tech, told Autocar in February that solid-state batteries were still too expensive and that current lithium-ion batteries have “a long way to go.”
Electrek’s Take
German automakers are not the only ones advancing the promising new battery tech. Global battery leaders CATL and BYD are also expected to launch EVs with all-solid-state batteries over the next few years.
Sun Huajun, the CTO of BYD’s battery business (Shenzhen BYD Lithium Battery Co), said earlier this year that the company expects its first EVs with all-solid-state batteries to arrive in 2027. Production will be limited for the first two years, but by 2030, BYD expects ASSBs to enter the mass market.
In the initial phase, BYD will use a sulfide-based solution in some of its higher-end models. Like BYD, CATL reportedly plans to begin production of all-solid-state EV batteries in 2027, but in small volumes.
Several others, including Hyundai, Nissan, Stellantis, Toyota, and Honda, are racing to develop the next generation of EV batteries.
Which will be the first to launch all-solid-state EV batteries on a mass scale? CATL and BYD already lead the market by a wide margin, but others are quickly advancing with on-road testing. Let us know your thoughts in the comments.
Global mining and construction equipment giant Liebherr recently rolled out its first-ever battery electric crawler excavator, setting a new standard in heavy earth-moving equipment capabilities with low noise levels and zero local emissions.
The company’s official copy is characteristically low-key, with an emphasis on the facts and features instead of hype:
The new model completes the product range of Liebherr crawler excavators produced in Colmar (France). It is particularly quiet and emission-free. It generates the same output as a diesel machine in the same category and is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.
Despite the lack of excitement in the release copy, there is a lot of excitement about the R 920 G8-E’s innovative new control cab philosophy.

Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USer Interface), the system integrates intelligent control logic with advanced machine learning capabilities to give operators a highly customizable interface that can follow them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the learning curve for operators on a given job site.
Liebherr says INTUSI improves both operational efficiency and user comfort on Liebherr job sites through the integration of a number of new features. From the press release:
Haptic feedback – vibrations alert the operator to critical conditions—such as reaching dynamic device limits—enhancing situational awareness and speeding up reaction times.
Optical feedback – integrated RGB LEDs on the joystick provide real-time visual cues about device status and servo control, ensuring clear communication without distraction.
Functional safety – control elements with status LEDs allow safe operation of critical functions—without requiring two-handed input—streamlining workflow while maintaining safety standards.
Hand detection – capacitive proximity sensor detects the operator’s hand automatically, enabling seamless activation of controls only when needed.
Display navigation – a mini-joystick embedded in the handle allows for quick and efficient navigation of the display interface, reducing the need to reach for external controls.
Ergonomics – multi-stage handle height adjustment ensures optimal comfort and usability, adapting to different operator preferences and working conditions
In addition to the INTUSI-powered custom cockpit, the new Liebherr R 920 G8-E electric excavator ships with your choice of either a 188 or 282 kWh high capacity li-ion battery, which is capable of 150 kW DC fast charging. Fast enough, in other words, to power up the machine during shift changes, if needed.
Electrek’s Take
R 920 G8-E electric crawler excavator; via Liebherr.
Since then, Fortescue has used the machine to move millions of tons of dirt, and has ordered several more. And, because everything from excavators to loaders to heavy trucks are built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo power, so there’s a degree of openness baked into those systems already. Liebherr is just taking that to the next level by installing an electric drive motor in place of an internal combustion engine, and I expect this excavator will be the first of many such machines from the brand.

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
