2027 Mercedes-Benz EQS 450+ travels 539 miles in range test

The 2027 Mercedes-Benz EQS 450+ drove 539 miles without stopping to charge in an Edmunds range test.

The electric sedan has a 122 kWh battery and an EPA-estimated range of up to 467 miles.

Its test result was 72 miles above that estimate, and Edmunds said it was the longest-range electric sedan it had tested.

The only electric vehicle mentioned that went farther was the Cadillac Escalade IQ, which traveled 558 miles.

The new EQS also charged faster than its predecessor, adding 825 miles of range in an hour during the test.

Edmunds designed the test to reflect everyday driving, with a mix of city and highway roads and an average speed of 40 mph.

The results show how range and charging performance have improved, though the test does not establish how every driver will fare.

The sources do not say when the 2027 EQS will go on sale.
