Borne from a goal to build an electric car that consumes less than 10 kilowatt-hours of energy per 100 kilometers (6.2 miles per 100 kWh), the Mercedes-Benz Vision EQXX concept debuted in January with a claimed range of 621 miles (or 1,000 kilometers) per charge. But talk is cheap and promises like those are only worth about as much as the paper they’re printed on, so Mercedes-EQ put its aerodynamic baby through a real-world torture test.
Driving the 628 miles (1,008 km) from Mercedes’ Electrical Software Hub in Sindelfingen, Germany, to the Mediterranean community of Cassis, France, the ultra-aerodynamic EQXX actually made the trip in a single charge while consuming only 8.7 kWh per 100 kilometers. At the end of the journey, the car was even indicating it had another 13 percent or so left in its battery, good for another 80 miles or so.
