Mercedes-Benz announced that the Vision EQXX, its electric concept car, successfully completed a long-range test drive of more than 1,000 km, the equivalent of more than 621 miles on a single charge of its battery.
The tour began in the city of Sindelfingen, home to one of the main Mercedes-Benz factories in southern Germanycontinued through Switzerland and Italy to finally reach its final destination in the port town of Cassis, east of Marseille, on the French Côte d’Azur.
The Vision EQXX traveled at an average speed of 54 mph through highly diverse topography with temperatures ranging from 37 to 64 degrees Fahrenheit (3 to 18 degrees Celsius). Mercedes-Benz said the Vision EQXX’s battery charge level on arrival in Cassis was around 15 percent, leaving the vehicle with an estimated range remaining of around 140 km, or 87 miles. Nothing bad.
The average consumption of the Vision EQXX during the tour was 8.7 kWh per 100 km (7.1 kWh per 62 miles), which according to the manufacturer is a new efficiency record. This figure is well below the estimate: 10 kWh per 100 kilometers that Mercedes-Benz had advanced when it presented the concept vehicle to the public earlier this year. The manufacturer’s initial estimate was based on computer simulations of real-world traffic conditions.

The Mercedes-Benz Vision EQXX was created with the purpose of studying how to increase the efficiency in the use of energy in electric vehicles. The results of this test indicate that the manufacturer is on the right track. In addition, he said that he not only viewed the Vision EQXX’s autonomy as completely realistic, but also that many of the technological advances that made it possible will be integrated into future production vehicles.
An interesting aspect of this test lies in the fact that it was carried out under completely realistic and far from ideal conditions for energy efficiency in an electric vehicle. The route followed by the Vision EQXX did not include highways, but rather steep mountain roads and areas with construction work, rural routes and other conditions far from a perfect highway. The vehicle also faced a wide range of temperatures, although it never encountered figures below freezing that tend to affect the performance of electric vehicles.
