Figures from the Environmental Protection Agency (EPA) reveal that the 2022 Mercedes-Benz EQS 450+ can travel 350 miles (563 km) on a charge. However, as Edmunds recently discovered when conducting a real-world range test of the EV, it can travel much further than that.
The publication tests every electric vehicle on the same real-world driving loop in Los Angeles and the EQS 450+ it was testing was light on options and fitted with the standard 20-inch wheels wrapped in Goodyear Eagle F1 Asymmetric 5 tires measuring 255/45 at all four corners, all pumped to 41 psi.

Over the course of 12 hours, Edmunds managed to drive the EQS 450+ for 422 miles (679 km), a full 72 miles (115 km) beyond the EPA figure. This also gives the EQS 450+ the highest driving range of any EV tested by Edmunds, beating out a 2021 Tesla Model 3 Long Range which achieved 345 miles over the same driving loop. In third place sits the 2021 Tesla Model S Plaid with 345 miles of range, just ahead of the Ford Mustang Mach-E California Route 1 Edition with 344 miles of real-world range.
Edmunds notes that its testing figures are more accurate than those published by the EPA. After all, the EPA’s figures come from tests conducted on a dynamometer set up to simulate city and highway routes. The total distance traveled is then multiplied by a correction factor to accurately reflect the range that drivers can expect to achieve in the real world.
By comparison, Edmunds’ test is conducted on a mix of city and highway roads (approximately 60 percent city, 40 percent highway) until the battery is almost entirely empty. The miles traveled and the indicated remaining range are then added together.
