The solid-state battery pack allows for a 25% increase in range without adding size or weight compared to current lithium-ion batteries.

Over the next few months, Mercedes-Benz will further test the solid-state battery and its overall performance.
What could be called a major breakthrough in the sphere of electric vehicles, Mercedes-Benz claims to have launched the “world’s first solid-state battery vehicle from a global OEM.”
The German automaker has unveiled that a prototype EQS, equipped with a solid-state battery developed in collaboration with US startup Factorial Energy, has begun real-world testing.
“Mercedes-Benz engineers from the road and racetrack and Factorial cell engineers have worked together on delivering an all-new solid-state battery test program, which has brought the first car powered by a lithium-metal solid-state battery to the road,” said the automobile giant in a press release.
This is a major milestone in the transition from laboratory experiments to practical applications.
“The first laboratory vehicle tests were already conducted in Stuttgart at the end of 2024 to prepare for the road tests that started in February 2025,” added the press release.
Significant range improvement
The prototype EQS is projected to deliver an impressive 620 miles (1,000 kilometers) of range, based on WLTP testing. This represents a more than 25% improvement over the current EQS 450+ model.
While WLTP figures typically exceed EPA estimates, the vehicle is still expected to achieve a remarkable 527 miles under EPA standards, which easily rivals the range of the Lucid Air.
This extended range is attributed to Factorial Energy’s innovative solid-state battery technology, which replaces the traditional liquid electrolyte with a solid one.
This allows for higher energy density and enhanced safety, while also promising significant weight reductions.
Mercedes-Benz states that the solid-state pack delivers 25% more range within the same size and weight parameters as current lithium-ion batteries.
“Further weight and energy efficiency is achieved through passive battery cooling,” said Mercedes.

That is an improvement at least. How's the longevity I wonder?
Of the battery fire? I heard they can go a full week.
That's an improvement over the L-ions in Moss Landing - that fire blazed up a second time after a couple of weeks!
Wrap em up like a basket burrito and toss em in! Heavy metals tang seasoning...
Not mine. I was never gonna buy a Tesla unless the price dropped by 70%.
Was interested in the Chevy Bolt as a cheap commuter beater.
Circumstances changed and now I'm selling cars instead of buying.
I've never understood celebrity endorsements though because i spend most of my money logically after a lot of research.
No but all the people being bitches has influenced me to rent them when I can.
