Although many people have called the VISION EQXX a concept car, these people do not work at Mercedes-Benz. The company insists on calling it a research vehicle because it packs experimental projects from many research fields into one practical electric vehicle for the express purpose of testing results in real-world scenarios. During the VISION EQXX technology briefings on the day of our co-drive, Jasmin Eichler, Director of Future Technologies for Mercedes-Benz AG, said that the best of these lessons will be used in all Mercedes series vehicles.
Eichler says the goal of the VISION EQXX’s 1,000km road trip wasn’t simply to complete the ride on a single charge. For that, she says, they could have just put a bunch of extra batteries in the roof to extend the range. Instead, Mercedes-Benz set out to manufacture the most efficient electric vehicle to date by bringing together research innovations in the electric powertrain, battery, aerodynamics, lightweight body construction, infotainment and computing, and durable interior materials.
When Mercedes-Benz unveiled the VISION EQXX in January, the car had been in development for 18 months at that point, and Eichler said they weren’t sure it would cover the 1,000 km on a single charge. . Since then, the team has removed an additional 88 pounds from the car, bringing its curb weight down to 3,869 pounds. In the end, by the time the VISION EQXX arrived in Cassis after 1008 km, its battery was 15% charged, potentially allowing an additional range of 140 km (87 miles). It was on average only 8.7 kWh per 100 km travelled.
