Electric vehicles are here, like it or not, and car companies have turned their attention (and vast resources) to making sure range anxiety is a thing of the past. Since that concern is a major hurdle for most Americans, the appearance of a Mercedes-Benz machine with a four-figure range is A Big Deal.

Well, four figures in metric measures, anyway.

No, the EQXX isn’t going to show up in Mercedes dealerships tomorrow, nor will it likely stand cheek-to-jowl with today’s G-wagens and AMGs. What it does represent is an effort to make sure we’re not all driving soulless transportation pods that need recharging every 100 miles once the last internal combustion engine is shut off for good.

According to the company, the Mercedes-Benz EQXX utilizes a battery pack with less than 100kWh of usable battery energy content, a sum currently enjoyed by a number of EVs on the road today. Where the EQXX seems to pack on the range is in the aerodynamics department, with a claimed 0.17 coefficient of drag and curb weight of 3,850 pounds. The former is aided by lozenge-like styling decisions while the latter is helped along by the use of lightweight materials. Horsepower, if you’re wondering, is in the ballpark of about 200 ponies.

An estimated-in-a-simulation 600+ miles out of a 100kWh battery pack is no mean feat, given that Merc’s own EQS is good for about 200 less than that with a similarly-sized bundle of electrons. Sure, the slicktop shape of this Mercedes-Benz EQXX helps but the company is keen to point out their strides in battery technology. Rather than simply increasing the size of it, Benz and their partners say they have developed a completely new battery pack for this concept, achieving what they describe as “remarkable energy density” which means there’s more juice per square inch.

The increase in energy density comes in part from progress in the chemistry of its anodes. Their higher silicon content and advanced composition mean they can hold considerably more energy than commonly used anodes. Energy density is also aided by highly integrating the battery pack into the platform, creating more space for cells that keep tabs on weight. The battery development team also decided to experiment with an unusually high voltage, pushing that figure to more than 900 volts. Doing so apparently permitted the engineering boffins to gather data on such a setup with eyes on developing something similar for future road-going vehicles.

Other concepts baked into the EQXX include a new take on thermal management, with a so-called ‘cooling plate’ installed in the vehicle floor. That’s a solar panel on the car’s roof as well, responsible for contributing an estimated 25 miles of driving range under certain conditions (read: The California sun) by permitting ancillaries like infotainment to be powered by this source of harvested energy instead of the main battery.

Here’s a stat for your next pub quiz: Mercedes says the super-low drag coefficient makes the EQXX more aerodynamic than an American football. No word on if it will be picked off by Brandin Echols and returned to the 50-yard line.

    In profile it almost looks like it has tailfins. I dig it.

    Article left out a very interesting fact - So called "UBQ" materials are used in its construction. This stuff could be a game-changer (there's that phrase again) because it is made from trash. No need to have a separate sorting of recyclables. They use everything, including all to organic material. And unlike a lot of "miracle" developments that have super high costs or consume tons of water/energy to produce, this is actually supposed to be a viable operation. Search "UBQmaterials. Fascinating stuff.

      Nothing new here... Trabants have been made out of random bits of shredded and compressed garbage for decades.

  • Doc423 Well said, Jeff.
  • Urlik My online research seems to indicate it’s an issue with the retaining clips failing and allowing the valve spring retainers to come out. This results in the valve dropping into the cylinder.
  • EBFlex Typical Ford. For those keeping track, Ford is up to 44 recalls for the year. Number one recalled manufacturer (yet again) by a wide margin.
  • Lorie Did they completely forget the damn 2.0 ecoboosts that have the class action lawsuit? Guess those of us that had to pay out of pocket for an engine replacement for a fail at 76k miles are out of luck? I will never buy a Ford again.
  • Mncarguy I remember when the Golf came out and all the car magazines raved about it. I bought an early one in the mid level trim, brown with a beige vinyl interior and a stick. I must have blocked out a lot about that car, because the only thing I remember is one day with my wife and infant in the car, the brakes went out! I could use the parking brake and made it home. There must have been other issues (beside an awful dealer who felt like they were doing you a favor even letting you come in for service) because I swore I'd never buy a VW again. I did get a new Beetle and later a Passat. That's another story!
