Mercedes-Benz Vision EQXX EV Concept Clears 1000km on a Single Charge
At the beginning of the year, Mercedes-Benz unveiled the Vision EQXX all-electric concept car – a research vehicle which the company touted as being able to do as much as 1000km on a single charge. A few months on, and the Vision EQXX has proven its chops on the road and has indeed demonstrated its incredible range.
In a trip from the company’s Sindelfingen R&D centre in southern Germany, across the Swiss Alps and Northern Italy, to the town of Cassis in southern France, it covered more than 1000km in everyday traffic, on a single battery charge.
The company says the journey started in cold and rainy conditions, and was undertaken at regular road speeds, including prolonged fast-lane cruising at up to 140km/h on the German autobahn and near the speed limit elsewhere. Mercedes also says the battery’s state of charge on arrival was around 15 per cent, amounting to a remaining range of around 140km, and the average consumption was 8.7kWh per 100km.
The long-distance drive was. Mercedes said, completed with the charging socket sealed and accompanied by an independent expert from certification body TÜV Süd.
The Vision EQXX is at the cutting edge of EV design and technology. It has 100kWh of charge on tap, and all that energy is stored in a pack that has 50 per cent less volume, and is 30 per cent lighter, than that used in the Mercedes EQS full-size luxury EV. This is thanks to some clever engineering and chemistry, and some innovative thinking that has come via Mercedes’ involvement in Formula One. A 900V electrical system should enable lightning fast recharging.
The company says the car’s electric drive unit is compact, lightweight, and highly efficient with 95 per cent of the energy from the battery ending up at the wheels.
There’s a 0.17 drag coefficient of the car to think about too which, along with weight-saving measures, regenerative braking, and low rolling-resistance tyres, add to the range ability of the car.
For extra help, there are even ultra-thin solar roof panels that feed the 12-volt battery which supplies power to auxiliary systems such as the navigation system. The added value is measurable through the load removed from the high-voltage battery, displayed by the onboard computer. Overall, the solar booster increases the range by more than two per cent, Mercedes says, or up to 25km on a journey of over 1000km.
“With our successful road trip to the South of France, we’ve shown that efficiency is the new currency,” said Markus Schäfer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology Officer responsible for Development and Purchasing.
“And this success also clearly speaks for our new collaborative development process, incorporating many learnings from the Mercedes-AMG F1 team and its cutting-edge expertise in electric powertrains.
“The Vision EQXX is the result of a comprehensive program that provides a blueprint for the future of automotive engineering. Many of the innovative developments are already being integrated into production, some of them in the next generation of modular architecture for compact and midsize Mercedes-Benz vehicles.”
