Mercedes-Benz’s Vision EQXX prototype EV has successfully undertaken a 1,000km journey across Europe on a single charge, traveling from Sindelfingen in Germany, across the Swiss Alps and Northern Italy, to its destination of Cassis on the Côte d’Azur.

Mercedes notes that the journey started in cold and rainy conditions, and was undertaken at regular road speeds, including prolonged fast-lane cruising at up to 140km/h on freeways and near the speed limit elsewhere. The battery’s state of charge on arrival was around 15%, amounting to a remaining range of around 140km, and the average consumption was a record-breaking low of 8.7 kWh per 100 kilometers.

The long-distance drive was completed with the charging socket sealed and accompanied by an independent expert from certification body TÜV Süd. Mercedes says that the trip officially confirms the effectiveness of its development approach – thinking holistically about efficiency from the drivetrain to aerodynamics and beyond.

“We did it! The Vision EQXX is the most efficient Mercedes ever built. The technology program behind it marks a milestone in the development of electric vehicles. It underpins our strategic aim to ‘Lead in Electric’,” commented Ola Källenius, chairman of the Board of management of Mercedes-Benz Group.
