Mercedes-Benz has finally revealed the design of its Vision EQXX concept which is supposed to have the longest range of any electric car on the road.

Mercedes claims that the Vision EQXX will have a range in excess of 1,000 km (620 miles) while also using less than 10 kWh per 100 km (more than 6 miles per kWh).

“The Mercedes-Benz VISION EQXX is how we imagine the future of electric cars,” says Ola Källenius, Chairman of the Board of Management of Daimler AG and Mercedes-Benz AG.

“Just one-and-a-half years ago,” he continues, “we started this project leading to the most efficient Mercedes-Benz ever built – with an outstanding energy consumption of less than 10 kWh per 100 kilometres. It has a range of more than 1,000 kilometres2 on a single charge using a battery that would fit even into a compact vehicle. The VISION EQXX is an advanced car in so many dimensions – and it even looks stunning and futuristic. With that, it underlines where our entire company is headed: We will build the world’s most desirable electric cars.”

Mercedes hopes that desirability will come from impressive efficiency, helped by stylish but effective design. The Vision EQXX has a drag coefficient of 0.17. Previously, super-slippery cars such as the Toyota Prius had coefficients around 0.25.

Sustainable materials made from recycled and plant-based fibres, as well as 3D printing to remove excessive waste, should give the Vision EQXX eco-credentials beyond its impressive range. Roof-mounted solar panels, meanwhile, give the battery up to an extra 25 km of range.

“Electric range sounds easy but is a complex technical challenge,” says Joerg Bartels, Vice President for Vehicle Engineering and Overall Vehicle Functions.

“The easiest way is to put a bigger battery in the car. However, this leads to diminishing returns due to size and weight. This is definitely not the smartest route and it’s also not the best use of scarce resources. With the VISION EQXX, we’re presenting the results of an extraordinary challenge: we pushed efficiency to a totally new level. And we explored new ways to increase the range of an electric car.” 

Mercedes has also been talking up the influence of its Formula 1 team in the Vision EQXX’s development. For example, its “lightweight lid was engineered jointly by Mercedes-AMG HPP and their chassis partners at Mercedes-Grand Prix.”

The Vision EQXX is also promising some smart car features. Working with California-based artificial intelligence experts BrainChip, Mercedes-Benz engineers developed systems based on BrainChip’s Akida hardware and software. When drivers say “Hey Mercedes,” for example, the software, structured along neuromorphic principles, will be able to answer your query “five to ten times” more efficiently than conventional voice command.”

It also has a “road trip sidekick” to help with navigation. “They might be in charge of the music selection. Or perhaps they’re clutching the travel guide, pointing out places of interest and fascinating nuggets of information along the way. They might even offer the occasional “tip” on driving style.”

Mercedes hasn’t revealed the details on pricing or whether a road-going version of the Vision EQXX will ever arrive.
