A 2027 Mercedes-Benz EQS sedan just traveled well over 500 miles in a real-world range test by Edmunds. It's an amazing result that shows range anxiety may finally be fading into the rearview—especially if you've got deep enough pockets.
When put through its paces, the Mercedes EQS 450+ covered 539 miles, surpassing its 467-mile EPA rating by a substantial 72 miles. That also makes it the longest-range sedan Edmunds has ever tested, beating out the Lucid Air Dream Edition by 34 miles. Keep in mind that Edmunds tests range on a route with a 60/40 split between city and highway driving, whereas the EPA aims for a 55/45 breakdown. In Edmunds' testing, only the Cadillac Escalade IQ has bested the EQS 450+’s range, covering a stunning 558 miles.
For 2027, Mercedes-Benz updated the EQS with some tweaks that helped boost its efficiency and range. The battery is now 122 kilowatt-hours, up from 118 kWh in the older model. The rear motor now has a two-speed transmission, and the whole platform has been upgraded to an 800-volt design. These upgrades already boosted the EQS’s stated range on paper. Overdelivering in the real world confirms that the range anxiety argument against EVs is only getting harder to make.
The EQS can't just drive farther than its predecessor. The updated 800-volt platform allows it to charge far more quickly.
Because of its long range, stellar efficiency, and strong DC fast-charging rate, Edmunds says it’s the third-fastest charging EV it has ever tested based on its miles-per-hour charging metric.
