Overview

• A lightly modified EQS drove 1,205 km from Stuttgart to Malmö on a single charge and arrived with about 137 km of range remaining.
• Mercedes reports the solid-state pack provides roughly 25% more usable energy than the standard EQS battery at comparable weight and size.
• The test used Electric Intelligence route planning on the A7 and E20, avoided ferries, and employed passive airflow cooling, with no average speed disclosed.
• The cells are supplied by US-based Factorial Energy within a program developed with Mercedes-AMG High Performance Powertrains.
• Mercedes characterizes the drive as a validation milestone and targets series production by the end of the decade as industry players pursue similar timelines.
