The 2027 Mercedes-Benz EQS 450+ electric sedan traveled 539 miles without stopping to charge during the Edmunds EV Range Test. This is 72 miles more than the U.S. Environmental Protection Agency’s (EPA) estimate, which puts the vehicle’s range at up to 467 miles, Electrek reports.

New Edmunds test result

According to the publication, the EQS 450+ became the electric sedan with the longest range among the models tested by Edmunds. It surpassed the Lucid Air, which had previously become the first electric vehicle in Edmunds testing to cover 500 miles. Only the Cadillac Escalade IQ achieved a higher result in these tests — 558 miles with a 205 kWh battery.

The updated EQS 450+ is equipped with a 122 kWh battery and an 800-volt electrical architecture. During the test, the vehicle consumed 29.6 kWh per 100 miles. For comparison, the 2025 EQS 450+ traveled 464 miles in a similar test and consumed 34 kWh per 100 miles.
