The Vision EQXX from Mercedes-Benz demonstrated its outstanding range and efficiency in the roads of Europe, travelling from Sindelfingen to Cassis on the Côte d’Azur.
During the journey, the car covered more than 1,000 km in everyday traffic, on a single battery charge. The journey started in cold and rainy conditions, and was undertaken at regular road speeds, including prolonged fast-lane cruising at up to 140 km/h on the German autobahn and near the speed limit elsewhere. The battery’s state of charge on arrival was around 15 percent, amounting to a remaining range of around 140 kilometres, and the average consumption was a record-breaking low of 8.7 kWh per 100 kilometres.
The Vision EQXX has thus taken electric vehicle efficiency to a whole new level – in real-life conditions and with independent proof. The long-distance drive was completed with the charging socket sealed and accompanied by an independent expert from certification body TÜV Süd. This officially confirms the effectiveness of the new Mercedes-Benz development approach – thinking holistically about efficiency from the drivetrain to aerodynamics and beyond, down to the tiniest detail, as well as working with even greater interfunctional collaboration and with external partners. This new blueprint for automotive engineering has delivered a new benchmark for electric vehicle efficiency and range, and the technology in the Vision EQXX will be deployed in upcoming series-production Mercedes vehicles.
We did it! Powering through more than 1,000 kilometres with ease on a single battery charge and a consumption of only 8.7 kWh/100 km in real-world traffic conditions. The Vision EQXX is the most efficient Mercedes ever built. The technology programme behind it marks a milestone in the development of electric vehicles. It underpins our strategic aim to ‘Lead in Electric’ – says Ola Källenius, Chairman of the Board of Management of Mercedes-Benz Group AG.
Challenging route profile and varying weather conditions
The Vision EQXX is packed with innovations. This software-defined research prototype is part of a far-reaching technology programme that combines the latest digital technology with Mercedes’ pioneering spirit, the agility of a start-up and the speed of Formula 1. The mission in developing the Vision EQXX was to break through technological barriers across the board. To show what is electrically “feasible”, the research vehicle completed a one-day road trip across several European borders: from Germany to Switzerland, on to Italy, past Milan and finally to its destination, the port town of Cassis near Marseille in the South of France.
The route profile – from motorway to mountain passes, including roadworks – and the weather conditions presented the Vision EQXX with a wide variety of challenges. Departing from the Sindelfingen R&D centre near Stuttgart in cold conditions, temperatures from start to finish ranged from 3 to 18 degrees Celsius. North of the Alps there was light rain and further south a gentle headwind blew in the sunshine. The various sections of the route helped document the effect of the many efficiency measures.
