The VISION EQXX from Mercedes-Benz has now taken to the roads of Europe and has demonstrated its range and efficiency. Travelling from Sindelfingen across the Swiss Alps and Northern Italy, to its destination of Cassis on the Côte d'Azur, it 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 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. For further information see the IDTechEx report on Charging Infrastructure for Electric Vehicles and Fleets 2022-2032.
"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.
"With our successful road trip to the South of France, we've shown that efficiency is the new currency. And this success also clearly speaks for our new collaborative development process, incorporating many learnings from the Mercedes-AMG F1 team and its cutting-edge expertise in electric powertrains. The VISION EQXX is the result of a comprehensive programme that provides a blueprint for the future of automotive engineering. Many of the innovative developments are already being integrated into production, some of them in the next generation of modular architecture for compact and midsize Mercedes Benz vehicles. And the journey continues. With the VISION EQXX, we will keep testing the limits of what's possible," says Markus Schäfer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology Officer responsible for Development and Purchasing.
The VISION EQXX receives extra energy via its fixed solar roof. The 117 solar cells feed the 12-volt battery, which supplies power to auxiliary consumers such as the navigation system. The added value is measurable through the load this removes from the high-voltage battery, displayed by the onboard computer. Overall, the solar booster increases the range by more than two percent - which adds up to a good 25 kilometres on a journey of over 1,000 kilometres.
Shortly before crossing the finish line in Cassis, the VISION EQXX gathered energy once more through recuperation. After 11 hours and 32 minutes of driving time, it ended its 1,008-kilometre road trip with a remaining range of around 140 kilometres. This means it could have set off again for a jaunt along the Mediterranean coastline without recharging.
The VISION EQXX has unequivocally proven the real-world potential of outstanding efficiency for electric vehicles. This first road trip to Cassis is a watershed moment on a much bigger journey that is far from over.
