The Mercedes-Benz VISION EQXX made a long-distance road trip from Sindelfingen, crossing the Swiss Alps into Northern Italy, and on to Cassis on the Côte d’Azur.

The 1,000 km (621 miles) began on a cold and rainy day. Speeds reached 87 mph on the German autobahn with the fast lane changes that come with high-speed travel. Upon arrival, 15% (140 km (87 miles) remained. The trip averaged a record-breaking low of 8.7 kWh per 100 kilometers (7.1 kWh per 62 miles).

In order to make sure things were tickety boo, VISION EQXX had its charging socket sealed and accompanied by an independent expert from certification body TÜV Süd. The test was intended to demonstrate the Mercedes-Benz development approach to efficiency. All details are taken into account, from drivetrain to aerodynamics and everything inbetween.

“We did it! Powering through more than 1,000 kilometers with ease on a single battery charge and a consumption of only 8.7 kWh/100 km (7.1 kWh per 62 miles) in real-world traffic conditions. 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’,” says Ola Källenius, Chairman of the Board of Management of Mercedes-Benz Group AG.
