The new Mercedes-Benz Vision EQXX concept is claimed to set new energy efficiency benchmarks to get a “real-world range of more than 620 miles” – 167 more than the EQS flagship EV. 

It has been conceived to challenge existing EV principles in a programme aimed at hatching new ideas, processes and innovations for adoption on upcoming EVs.

Chief technology officer, Markus Schäfer, said: “There are many, many elements of the vehicle which are very close to moving into series production,” he added. “We can look at the shape and form of the vehicle, and we are very close to the series car that we are going to see in 2024 with all the ingredients to make it one of the most efficient electric vehicles that exists”.

  • The rear-wheel-drive saloon is its high efficiency rating, which at more than 6.2 miles per kWh is almost double that of the Mercedes-Benz EQS on the WLTP test procedure – a figure that Mercedes says is the equivalent of more than 282mpg in a petrol car.
  • It has been achieved using a newly developed motor and a bespoke lithium ion battery, which, at just under 100kWh, has a lower overall energy capacity than the EQS – the longest-range version of which lasts 453 miles.
  • Using cells supplied by Chinese battery specialist CATL, the 1750kg EQXX’s new battery is also claimed to be “50% the size” of the EQS’s 107.8kWh pack and is some 35% lighter, at about 495kg.
  • Mercedes said that the new high-silicon-content battery operates at more than 900V and features “active cell balancing” – a process whereby energy is drawn evenly from each cell for enhanced efficiency at a cruise.
