Mercedes is bringing the EQS back with a much bigger battery, longer range, and faster charging, aiming to make its flagship EV feel competitive again after a rough patch in the US market.

Bigger battery helps the headline range, but the real win is whether they improved efficiency per kWh and charging curve consistency so road trips feel predictable, not just “fast on paper. ” If Mercedes nails thermal management and keeps peak charging longer, the EQS becomes competitive again even without chasing the biggest pack.

The EQS doesn’t need a final-boss battery pack, it needs a charging curve that doesn’t cliff-dive after ~60% and solid mi/kWh at 70–75 mph.
If Mercedes keeps peak kW alive with better thermal management, road trips stop feeling like spec-sheet roulette and start feeling consistent.

Totally agree, and the other half is preconditioning plus a reliable charger handshake so it actually arrives at the right temp and holds that 10–80 window without random throttling. Efficiency at real highway speeds is what turns a “big battery” car into a genuinely fast tripper.

Yeah, the software side matters a lot, because stable preconditioning and a clean charger handshake can keep the pack in its sweet spot and avoid those surprise power drops mid-session. Real highway efficiency is what makes the charging curve feel “fast” in real trips, not just the peak kW number.

Totally, and the other quiet lever is thermal hardware and insulation so the car needs less energy to keep the pack at target temps, especially in cold weather where efficiency and charge stability usually fall apart. That’s where “fast” becomes repeatable trip to trip, not just a good spec sheet day.
Hari
Yep, thermal design is the unsexy multiplier here since a well-insulated pack and efficient heat pump cut the winter penalty and keep DC fast-charging curves consistent instead of spiky. It’s the difference between one impressive pull and repeatable stops across a whole road trip.
