Mercedes Concept BEV Proves its 620-Plus Range

Mercedes-Benz has taken to a road trip to prove it’s latest BEV concepts credentials as a true mile-cruncher able to take on a holiday tour.

In a journey to mirror that of many European holidaymakers planning to drive from the cool of the continent’s north to the sun-drenched beaches of southern France, the Mercedes-Benz Vision EQXX proved its worth as a 620-plus mile traveller on a single charge. Travelling from Sindelfingen, Baden-Württemberg, in Germany, crossing the Swiss Alps into Northern Italy and then finally arriving at its destination of Cassis on the Côte d’Azur, the car managed the trip with about 15% of battery charge remaining, enough for another 86 miles.

The journey started in cold and rainy conditions, and was undertaken at regular road speeds, including prolonged fast-lane cruising at up to 86mph on the German autobahn and near the speed limit elsewhere. The average consumption was a record-breaking low of 8.7 kWh per 62 miles.

The long-distance drive was completed with the charging socket sealed and accompanied by an independent expert from the German certification body TÜV Süd. The automaker says the exhaustive attention to detail and efficiency throughout the car’s powertrain and aerodynamics has shown how even current BEV technology can achieve long-distance credentials. It’s a blueprint that will be deployed in upcoming series-production Mercedes-Benz vehicles.

Ola Källenius, chairman of the board of management of Mercedes-Benz, said: “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’,”
