At the beginning of 2022, Mercedes-Benz presented its Vision EQXX electric car technology platform with the goal of traveling 1,000 kilometers without intermediate charging. According to the Swabians, this has already been achieved: On its maiden voyage from Sindelfingen through the Swiss Alps and northern Italy to Cassis on the Côte d’Azur, the mid-range sedan covered more than 1,000 kilometers in real daily traffic with a battery. position.
The Vision EQXX started in the cold and rain, drove at normal speeds and, according to Mercedes, sometimes drove in the fast lane on German motorways at speeds of up to 140 km/h. A total of 1,008 kilometers were covered in 12 hours and 2 minutes at an average speed of 87.4 km/h. Battery charge level on arrival was around 15 percent, remaining range around 140 kilometers. “Average consumption exceeded all our requirements and was an all-time low of 8.7 kWh per 100 kilometers,” the automaker says happily.
The long-distance journey was made with a sealed charging plug and was accompanied by an expert from TÜV Süd. The 1,000 kilometer mark was broken through a new development approach for electric cars. “Thinking about efficiency beyond the powertrain and aerodynamics holistically down to the finest detail, as well as working more closely than ever across departments and with external partners, this concept worked 100 percent,” the Swabians said.
“We did it! We easily drove more than 1,000 kilometers on a single battery charge and consumed only 8.7 kWh/100 km in real traffic conditions,” says CEO Ola Källenius. “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 supports our strategic motto ‘Lead in Electric’”.
The road trip to the south of France proved that “efficiency is the new currency”, explains Markus Schäfer, Head of Development. “And the success also speaks volumes for our new collaborative development process, which incorporates a wealth of knowledge from the Mercedes-AMG F1 Team and its leading expertise in electric propulsion. Vision EQXX is the result of a comprehensive technology program that provides a blueprint for the future of automotive engineering.”
According to Schäfer, many of the developments for the Vision EQXX are already being integrated into production, some of them also in the next generation of the modular architecture for compact and mid-range vehicles planned for the middle of the decade. “And the journey continues. With Vision EQXX, we will continue to explore the limits of what is feasible”, emphasizes the manager.
According to Mercedes, the new Vision EQXX drive concept with an output of 150 kW (204 hp) achieves a benchmark efficiency of 95 percent from battery to wheels. The battery pack with an energy density of almost 400 Wh/l stores almost 100 kWh of energy with 50% less volume and 30% less weight than the EQS electric luxury sedan’s battery pack, which has been leader in this aspect to date. . 117 “ultra-thin” solar cells on the roof powered the battery system and provided an additional range of up to 25 kilometers. The e-car also sets new records for aerodynamics and weight reduction.
