German automaker Mercedes-Benz has introduced a new prototype that represents the future possibilities in EV range and efficiency. The Mercedes-Benz VISION EQXX features an ultra-efficient electric drivetrain, lightweight engineering and is styled with sustainable materials. While the EQXX remains a prototype, its initial specs are staggering, offering a wealth of optimism for future EVs from Mercedes.

Mercedes-Benz is a legacy German automaker that needs no introduction. As one of the global leaders in luxury autos, Mercedes has had the foresight to adapt its production strategy toward electrification, vowing to go “all-electric” by 2030.

To achieve this goal, Mercedes has implemented several new programs consisting of R&D and actual production to further global EV adoption. We are just beginning to see the beginning of this electrified strategy with Mercedes’ new EQ line of vehicles – particularly the recent EQS sedan.

In the US alone, 2022 will bring an EQB SUV as well as a second EV sedan called the EQE to join the EQS. Several other EV models will join other global markets as well as additional EQ models in coming years.

One EQ model that had been in development for a year and a half now is the Mercedez-Benz VISION EQXX EV, an ultra-efficient prototype first unveiled a year ago to the day. At the time, Mercedes-Benz COO Markus Schäfer spoke to the new EQXX:

As you may know, we have been working on translating our strategic ambition to ‘Lead in Electric Drive’ into a car for some time: Now, the VISION EQXX is set to become the most efficient electric vehicle we have ever built – with a real-world range of more than 1,000 km. And I’m extremely happy that it will be unveiled to the public very soon – on January 3, 2022.

While early teases of the VISION EQXX by Mercedes touted over 750 miles (1,200 km) of range, we now know the range is only 620 miles (1,000 km). This is still quite impressive, especially with all the other design features the public now has its first official glimpse of.

Mercedes-Benz VISION EQXX details and specs

As promised an entire year ago, Mercedes has officially unveiled its VISION EQXX prototype to the public, alongside some impressive technology drivers can expect to see implemented in future EQ models. The release from Mercedes describes the EQXX effectively:

The VISION EQXX is the result of a mission we set to break through technological barriers and lift energy efficiency to new heights. It demonstrates the gains that are possible through rethinking the fundamentals from the ground up. This includes advances across all elements of its cutting-edge electric drivetrain as well as the use of lightweight engineering and sustainable materials. Complete with a barrage of innovative and intelligent efficiency measures, including advanced software, the VISION EQXX allows us to explore new frontiers of efficiency.

Check out the lengthy press release above for all the details, but we’ve outlined some of the main features below:

  • Energy efficiency – Mercedes-Benz engineers were able to deliver energy consumption in the EQXX that is less than 10 kWh per 100 km (~62 mi). That’s an efficiency of more than 6 miles per kWh. Mercedes translated this figure to fossil-fuel consumption, and it is comparable to about 1 liter per 100 km, or 235 mpg.
  • New electric drivetrain – The super-efficient electric drivetrain built in-house offers 95% efficiency, meaning up to 95% of the energy from the battery ends up at the wheels. It’s important to note the drivetrain only provides a max output of 150 kW.
  • Energy dense battery pack – Mercedes battery chemists squeezed the energy of its EQS into the dimensions of a compact. The result for the VISION EQXX is a battery pack with nearly 100 kWh of energy, but with 50% less volume and 30% lighter than the EQS pack.
  • Lower drag than a football – The drag coefficient on the EQXX prototype is just 0.17㏅ making it more aerodynamic than a football, as well as the 0.20 ㏅ on the new Mercedes-Benz EQS.
  • Solar panel roof – Ultra-thin roof panels harness the power of the Sun to provide the EQXX’s battery system with up to 25 km (15.5 mi) of additional range.
  • Impressive EV range – The above features combine to provide the VISION EQXX with over 620 miles (1,000 km) of range on a single charge.
  • Sustainable materials – Mercedes has implemented recycled and plant-based materials to help remove waste from landfills and lower its carbon footprint during vehicle production.

Once again this is a prototype representing tech we may see on future series production from Mercedes-Benz, but it’s still exciting nonetheless. You can check out the full world premiere of the Mercedes-Benz VISION EQXX in the video below:


If you like the EQXX concept you might love what Lightyear has been doing. Their ultra efficient vehicle, which actually looks a little like the EQXX, also has solar roof for recharging along the way. Born out of a solar race car, the Lightyear actually has more solar but less battery topping out at 60kWh which yields “only” 710km of range. Given the reality of normal driving, 60kWh is probably more than enough for a real car. That’s another difference: Lightyear actually expects to begin deliveries this year.

And if you like Lightyear and the EQXX, but are thinking to yourself, that’s not efficient enough, check out what Aptera has been doing. Their 3-wheeler hopes to achieve 1600 kms of range with a 100kWh battery and closer to 1000km with the 60kWh option. That’s before you count on sun miles.
