The most efficient versions now are rated at 780 km on the WLTP cycle, or 485 miles. On the more conservative EPA cycle we expect something more than 400 miles for the more efficient EQS 450+, but don’t expect that figure to be released until the fall on-sale date. That compares to the 412 miles reached by the Tesla Model S and the 500-plus miles promised by the Lucid Air launch edition.
