Here is a little more on range as reported on "The Verge".
(Mercedes-Benz USA initially sent out press materials that said the EQC’s estimated range was both “around” and “up to” 200 miles. A representative for the company told The Verge after publish: “Our colleagues in Stuttgart have advised us that the preliminary estimated range figure for the EQC of 200 miles for the U.S. is incorrect.”)
While Mercedes-Benz teased a range of around 300 miles with the concept version, the production EQC will potentially travel less than that on a full charge. Mercedes-Benz parent company Daimler says it estimates the EQC will get about 280 miles per charge, but that’s based on the notoriously optimistic NEDC standards used in Europe. For comparison, the Jaguar I-Pace is rated for 300 miles with NEDC but is rated at 240 miles with the EPA in the United States.
