In early 2022, Mercedes-Benz introduced its Vision EQXX electric car technology platform with the goal of driving 1,000 kilometers without intermediate charging. According to the Swabians, it’s now done: on its maiden voyage from Sindelfingen via the Swiss Alps and northern Italy to Cassis on the French Riviera, the mid-range sedan covered more than 1,000 kilometers in real daily traffic with a battery charge.
The Vision EQXX started in the cold and rain, drove at normal speeds and, according to Mercedes, was sometimes in the fast lane on German autobahns at up to 140 km/h. In total, 1008 kilometers were covered in 12 hours and 2 minutes at an average speed of 87.4 km/h. The battery charge level on arrival was around 15%, the remaining range around 140 kilometres. “The average consumption exceeded all our requirements and reached a record level of 8.7 kWh per 100 kilometers”, rejoices the manufacturer.
The long-distance journey took place with a sealed charging socket and was accompanied by an expert from TÜV Süd. The 1000 kilometer mark has been passed thanks to a new approach to the development of electric cars. “Thinking about efficiency beyond powertrain and aerodynamics holistically down to the last detail, as well as working more closely than ever before across departments and with external partners – this concept has worked 100%,” said the Swabians.
“We did it! We easily covered more than 1,000 kilometers on a single battery charge and a consumption of only 8.7 kWh/100 km in real traffic conditions,” says CEO Ola Källenius. Vision EQXX is the most efficient Mercedes ever built.The technology program behind it marks a milestone in the development of electric vehicles.This underpins our strategic claim “Lead in Electric”.
The road trip in the south of France showed that “efficiency is the new motto”, explains Markus Schäfer, head of development. “And the success also speaks clearly to our new collaborative development process, which incorporates much of the knowledge of the Mercedes-AMG F1 team and its cutting-edge know-how in electric propulsions. The Vision EQXX is the result of a comprehensive technology program that provides a blueprint for the future of automotive engineering.
According to Schäfer, numerous 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 mid-range. the decade. “And the journey continues. With the EQXX Vision, we will continue to explore the limits of the feasible”, underlines the leader.
According to Mercedes, the new drive concept of the Vision EQXX with an output of 150 kW (204 hp) achieves a benchmark efficiency of 95 percent from the battery to the wheels. Battery pack with an energy density of nearly 400 Wh/l stores nearly 100 kWh of energy with 50% less volume and 30% less weight than the electric luxury sedan’s battery pack EQS, which is currently the leader in this field. . 117 “ultra-thin” solar cells on the roof powered the battery system and provided an additional range of up to 25 kilometers. The electric car also sets new records for aerodynamics and weight reduction.
