There is no doubt that Germany and Italy have an excellent reputation for building exciting and impressive cars. The
Mercedes-Benz
Vision EQXX is a 2022 concept meant to carry on such a reputation and break new ground in the world of
hyper-efficient electric vehicles
.
Vision EQXX sets out to develop new standards for electric range and efficiency by demonstrating the ability of electric vehicles to be efficient and luxurious for consumers.

What is the Vision EQXX?

The Vision EQXX borrows some traits from the smaller CLA, but has been fleshed out for a more aerodynamic feel.
Mercedes’ latest foray into the concept world could be a watershed moment among EVs. With the Vision EQXX, Mercedes has pushed to develop a vehicle with a range of more than 1000 kilometers on a single battery charge—which translates to a consumption rate of less than 10 kWh of energy per 100 kilometers.
With a lightweight design, innovation in battery, and new equipment, the German carmaker hopes that the Vision EQXX will cement the status of Mercedes-Benz as a leader in the automotive industry.

The Mercedes-Benz Vision EQXX design

Mercedes-Benz has had unconventional innovations, especially in the realm of aerodynamics and
energy efficiency
. Specifically, they have focused on drag coefficient—a good measure for how efficiently a car responds to airflow. After extensive engineering and tireless testing, the EQXX’s drag coefficient is 0.17—one of the lowest around.
But it isn’t a completely new car altogether.
Instead, Mercedes-Benz drew into its own catalog, creating a car with a smaller front face than the compact CLA. The model will also have a narrower rear wheel track that enables the air to circulate more efficiently.
The Vision EQXX has applied a mixture of sustainable materials such as bamboo, cactus, and vegan silk to the interior design. Such a composition shows that there is still a possibility of balancing luxury and nature when developing a car.

The Mercedes-Benz Vision EQXX engine specs, performance efficiency, and battery design

With the Mercedes-Benz Vision EQXX, long-term mobility will be measured based on its 95% energy efficiency.
It thus implies that 95% of the energy stored in the battery is transferred to the wheels. In comparison, an automobile with an efficient internal combustion engine achieves roughly 30%, and a typical human long-distance runner achieves around 50%.
Mercedes-Benz engineers collaborated with High-Performance Powertrains (HPP) and Mercedes-Benz Grand Prix (MGP) to build a highly efficient and compact electric powertrain as well as a lightweight battery housing.
They've spent decades minimizing mechanical friction so that power can reach the racetrack with the least amount of loss.
According to
Motor1
, Mercedes-Benz engineers have improved the battery's energy density to 200 Wh/kg, consequently allowing the Vision EQXX's battery to store 100 kWh while having a space of 50% less and 30% less weight compared to other batteries with the same capacity.
The company has applied state-of-the-art silicon anodes alongside ultra-weight items from Formula One, significantly improving battery capacity.
Our friends at
Autocar
have reported that the Vision EQXX has an electric system that supplies power to many auxiliary sections and solar cells from the roof that helps in drawing additional energy. These attributes lower the high-volt system's energy demand, allowing the car to achieve a higher range.
The combination of features can help produce up to 25 kilometers of additional range for a long-distance journey on a single day.
