Mercedes EQS Breaks 749-Mile Record with Solid-State Battery: The Future of EV Range Is Here
Langstrecken-Test erfolgreich bestanden: EQS mit Festkörperbatterie meistert 1.205 km mit einer einzigen Batterieladung // Long-distance test successfully completed: EQS with solid-state battery covers 1,205 km on a single charge
Mercedes-Benz just set a new benchmark for electric mobility with a lightly modified EQS sedan traveling 749 miles on a single charge from Stuttgart, Germany to Malmö, Sweden arriving with 85 miles still left. This isn’t a concept car stunt, it’s proof that solid-state batteries are ready to move from theory to reality.
For years, EV adoption has been slowed by range anxiety and slow charging. This drive shattered both concerns in one sweep. Powered by Factorial Energy’s lithium-metal cells and refined with Formula 1 engineering, the EQS showed that nearly 750 miles of real-world driving is possible without stopping to plug in. The pack maintained a similar size and weight to today’s lithium-ion batteries while offering 25% more usable energy, validating solid-state as the next leap forward in electrification.
Compared to rivals, Mercedes is now in a league of its own. Tesla’s longest-range Model S hits 405 miles, Lucid’s Air Dream Edition manages 516, and even Mercedes’ own Vision EQXX falls short of this milestone. Toyota and BMW continue to talk prototypes, but Mercedes has put real miles under its tires. If production arrives by the late 2020s as planned, Stuttgart could dominate both luxury and long-range EV markets.
This technology matters because it changes the math of EV ownership. If drivers can go nearly 800 miles on a single charge, the pressure to build ultra-fast chargers every 20 miles eases, road trips become practical, and range anxiety becomes history. For long-distance commuters, cross-border travelers, or luxury buyers who want confidence without compromise, solid-state batteries are a game-changer.
That said, affordability isn’t here yet. Solid-state systems will debut in flagship sedans and SUVs before reaching mass-market EVs. Early adopters will pay a premium and may play the role of testers as the technology scales. But the long-term promise is undeniable. Solid-state batteries could extend beyond cars to aviation, trucking, and grid storage, reshaping energy use far beyond the highway.
Mercedes-AMG’s involvement signals this is no lab experiment. The company is serious about hitting production by decade’s end, and if successful, this moment may be remembered as the turning point when EVs became inevitable. For now, the EQS sits at the top with nearly 750 miles of bragging rights and a roadmap that could redefine mobility.
