Mercedes-Benz has confirmed the launch of the EQXX concept at cess consumer electronics show on January 3, a demonstration of low wind resistance and high energy efficiency, which the original manufacturer claims to be able to reach a distance of 1,000 kilometers on a single charge. Before the publication, Mercedes-Benz released the trailer information three times, in addition to a very limited increase in appearance exposure, the focus is still on the aerodynamic design.
Reaching 1,000 km of range is no longer difficult for some fuel models or fuel trams. But for mass-produced electric vehicles, this four-digit threshold is still not easy to achieve, even if Tesla and Lucid have models with a range of more than 800 kilometers, but electric vehicles are not as simple as cars to increase fuel tank capacity, increasing power is equivalent to increasing weight, not only will greatly drag down control and safety, the increasing weight of the car will also lead to a continuous reduction in battery stack benefits.
Therefore, Mercedes-Benz's EQXX Concept car has adopted the method of improving efficiency, and reducing wind resistance is a good start. At present, the original factory has not disclosed what the actual drag coefficient of EQXX is, judging from the 0.20 Cd of the EQS production car, it should be more impressive. Not only that, but EQXX's battery also increases energy density by 20%, so it can increase the endurance without increasing the weight of the battery.
The latest trailer hints at some information that has not been exposed in the past, such as the mention that solar energy will be used, so the car may be equipped with a solar power generation system. During the development of the EQXX, Mercedes-Benz used closed-loop system software, a technology that allows the brand to test and drive vehicles in digital simulations on computers.
Aerodynamics was a key factor in creating the appearance of the EQXX, and Mercedes-Benz, which has a wealth of experience in F1, has a lot of experience in how to adjust the aerodynamic performance of the vehicle to perfection. But it still hurts the designers, after all, EQXX and F1 are not at the same goal. To challenge 1,000 km of range, engineers and designers analyze birds, sharks and other creatures that attach great importance to aerodynamics or fluid mechanics, and study how to reduce drag and improve energy efficiency from every detail and shape. In the end, this result was the EQXX that appeared on January 3.
