The Mercedes-Benz EQS, the current electric flagship from the German luxury car maker, has been rated for a combined 350-mile range by the EPA earlier this year. The American testing process is known for being stricter in its estimates than its European counterpart, causing some issues with various car makers in the past. And yet, those proved to be conservative estimates at the end of the day.
At least according to an independent test, carried out by Edmunds, claiming that the real-life range they got out of the car went over 420 miles. The test was carried out around a test loop used by Edmunds for each of the electric vehicles that happen to get delivered to their doorstep. During their 12-hour run with the car, the EQS 450+ which has a 107.8 kWh battery, they managed to cover 422 miles, beating the EPA estimate by no less than 72 miles.
Their tester was a rather modest build, riding on 20” wheels and it did have 41 psi of pressure in the tires, using Goodyear Eagle F1 Asymmetric 5 tires measuring 255/45 at all four corners. That’s basically what you get as standard on the EQS. With this result, the EQS 450+ became the car with the longest range they ever tested, beating the Tesla Model 3 in the process, which had previously been the champ, with 345 miles covered, in the same testing loop.
As it stands right now, the top three is completed by the Tesla Model S Plaid with the same 345 miles of range, barely ahead of the Ford Mustang Mach-E California Route 1 Edition with 344 miles of real-world range. According to Edmunds, its testing procedure is more precise compared to the EPA one, as it actually includes real on-road driving, not just tests run on a simulator.
