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.
The rakish compact saloon is the latest in a long line of design studies made public by the German car maker. 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.
The result is a car that, despite conforming to all existing German roadworthiness regulations and providing seating for four adults, is claimed to set a new record for aerodynamic efficiency, with a drag rating of below 0.18Cd. This compares with the 0.20Cd of the EQS.
The development programme for the EQXX is said to have seen key contributions from UK-based Mercedes-AMG High Performance Powertrains, which builds the complex V6 turbo-hybrid powertrains for Mercedes’ Formula 1 cars.
In developing the one-off prototype, Mercedes not only focused on the drivetrain but also challenged its designers and engineers to rethink other key areas of EV development.
Central to the outstanding range achieved by 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 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.

One evening, two years ago, George Pappas was being driven down his local high street by a mate and mulling over whether to replace his Mk4 Golf diesel, a recent purchase that was boring him to death, when his girlfriend, also in the car, spotted an old BMW 3 Series at the side of the road with a 'for sale' sign in the window.
