Mercedes-Benz’s EQXX electric concept car traveled 1,000 km on a single charge

Mercedes-Benz takes the efficiency of electric vehicles seriously, and the company proves it with its EQXX electric car concept.

The car traveled from Sindelfingen, a town in southern Germany, to the town of Cassis on the French Riviera, France – a journey of 1,000 kilometres, or 621 miles – on a single charge. According to Mercedes-Benz, the journey was undertaken at normal road speeds, including a long cruise of 140 km/h on the German autobahn, and in various weather conditions, including cold and rainy conditions.

At the end of the trip, the car still had 15% battery charge, which would have been good for another 140 kilometers (87 miles). Mercedes-Benz claims that the car’s average consumption was “a record 8.7 kWh per 100 kilometres”.

The aerodynamic shape combined with battery efficiency gives this car over 600 miles of real-world range.

“With our successful road trip in the south of France, we have shown that efficiency is the new motto. And this success also speaks clearly to our new collaborative development process, incorporating many lessons from the Mercedes-AMG F1 team and its cutting-edge expertise in electric powertrains. (…) With the VISION EQXX, we will continue to test the limits of what is possible,” Markus Schäfer, Mercedes-Benz Technical Director responsible for development and purchasing, said in a statement.


Mercedes-Benz’s Vision EQXX is an idealistic EV concept

Originally announced in January 2022, the Vision EQXX is a futuristic concept focused on aerodynamics and battery efficiency. Its stellar range should be further improved with solar panels on the roof, which could add around 24 km (15 miles) of range.

Mercedes-Benz shared some details on how it achieved this feat in a blog post. For example, at highway speeds, the extremely low drag coefficient of just 0.17, along with specially developed Bridgestone tires, helped prevent the Vision EQXX from draining its battery too quickly. And when crossing the Swiss mountains, the lightweight construction of the car (it weighs 1,755 kilograms) saved energy. Regenerative braking and the sunroof also played their part by harvesting energy from the batteries.

It remains to be seen how well those numbers hold up when the Vision EQXX is transformed into a vehicle you can actually buy. For the moment, it is not known when this can happen.
