The Mercedes-Benz Vision EQXX concept is finally here as the brand's expression of the pinnacle of automotive efficiency. A production version is also on the way.

The EQXX's impressive efficiency allows it to cover over 1,000 kilometers on a charge. This would be enough to go from Berlin, Germany, to Paris, France, without needing to plug in the sedan. Mercedes claims the average American driver would only need to recharge the vehicle twice a month.

Mercedes isn't disclosing the capacity of the EQXX's battery beyond saying that the figure is less than 100 kilowatt-hours. The company touts a few impressive details about the pack, though. It has 50 percent less volume and is 30 percent lighter than the one in the EQS. The maximum system voltage is 900 volts. The battery and the frame that carries it weighs around 495 kilograms).

Power comes from an electric motor that makes 201 horsepower (150 kilowatts). Mercedes touts that the powertrain is so efficient that 95 percent of the energy ends up at the wheels.

There's a solar panel with 117 cells is on the roof, and the vehicle uses it to power many of the ancillary electric systems, like the blower for the HVAC system, lights, and infotainment system. A separate lithium-iron-phosphate battery stores the energy. In ideal conditions, this tech can free up 25 kilometers of range.

It's not obvious when looking at the EQXX in photos, but the vehicle is fairly compact. The sedan has a length of roughly 463 centimeters and a wheelbase of 280 centimeters. For comparison, the latest C-Class is 475 centimeters long and rides on a 286.51-centimeter wheelbase.

The EQXX is also fairly light by EV standards. It weighs 1,750 kilograms. That's only a bit more than a 2022 Mercedes-Benz C300 Sedan at 1,675 kilograms.
