Mercedes-Benz Korea’s electric sedan “The New EQS,” which was officially released in Korea in November last year, is drawing attention as it provides a differentiated luxury experience through high-level indoor air quality and excellent NVH (noise, vibration, and discomfort) removal performance.
The New EQS has a variety of innovative technologies suitable for the status of high-end electric sedans, including exterior designs implementing progressive luxury, interior with state-of-the-art technologies, and various advanced convenience and safety systems that stimulate five senses. Among them, The New EQS has prioritized strengthening NVH-related performance from design to electric powertrain design. Mercedes-Benz is said to have met the high standard for comfortable and quiet driving unique to the brand.
The aerodynamic design of The New EQS made a decisive contribution to indoor quiet. The exterior features a one-bow silhouette like a single bow and a cap-forward fastback style designed to propel the vehicle’s A pillar forward and position the C pillar behind it. By applying a seamless design with reduced joints, air resistance is minimized and indoor quietness is improved.
Wind noise from The New EQS was also minimized through body finish and sound insulation. The gap in the vehicle body was filled with special foam to prevent low-frequency noise, and in particular, the sealing process between the vehicle door and the window prevented external noise effectively by paying special attention to the finish. Double-junction glass (laminate glass) is applied to the side and rear of the vehicle to provide maximum comfort and safety during long-distance or high-speed driving. In addition, Mercedes-Benz has reduced noise and vibration through optimization of motor parts and arrangement, and has implemented the best quietness that can hardly feel road noise.
The New EQS is equipped with an airmatic air suspension that automatically adjusts the suspension according to driving conditions, speed and load, providing a comfortable ride on any road or road conditions. The adaptive damping system controls each wheel individually and adjusts the air suspension according to the driving speed through sophisticated sensors in the level control system. In sports mode, when driving at a speed of 120km per hour, the body lowers by 20mm, reducing air resistance, and when it falls at a speed of less than 80km per hour, the body height returns to its default position. In addition, the body can be manually raised about 25mm at 40km per hour, and when it reaches 50km per hour, it will automatically return to its original body height.
In addition, The New EQS is basically applied with Energizing Air Control Plus, which includes a large Hepa filter, purifying external air such as fine dust, particulate matter, and pollen to a very high level of filtration, providing a pleasant driving environment for passengers.
The New EQS, which was built based on a modular architecture exclusively for electric vehicles with excellent scalability and flexibility, used the inside of the front bonnet, where the existing internal combustion engine engine was located, as a space for mounting a huge HEPA filter. The size of the Hepa filter mounted on the bonnet is 596mm wide, 412mm long, and 40mm high, which is four times the size of the German industrial standard A4 paper, and the volume is about 10 liters.
The New EQS implements a highly clean environment inside a vehicle through a three-step air filtering process. First of all, the free filter located at the edge collects large particles such as leaves, eyes, and sand, and then the fine fiber layer of the HEPA filter collects ultrafine dust of 2.5~0.3 PM, whose particle size is smaller than 2.5μm. A filter certified ‘DIN EN 1822’, a strict and advanced European method of high-performance filter test, removes more than 99.65% of particles of any size and reduces contaminants to a level similar to that of a clean room or operating room.
As a final step, The New EQS filters out unpleasant odors and particulates as well as sulfur dioxide and nitrogen oxides. Sulfur dioxide and nitrogen oxides are filtered by special activated carbon in hepa filters and indoor air filters. About 600g of activated carbon made of coconut shells was used for the Hepa filter, and through a special pore structure, it has a large adsorption area of about 150 soccer fields.
The filter has obtained OFI certification from Austrian laboratories, proving that it effectively reduces bacteria and viruses. In fact, Energized Air Control Plus achieved a virus capture rate of more than 85% and a bacterial capture rate of more than 90%, in tests based on scientific analysis. These indoor and outdoor particulate levels can also be checked in real time through Mercedes-Benz’s MBUX infotainment system, and it is also equipped with a function to encourage vehicles to close windows and sunroofs in case of poor outside air quality. It is also possible to clean up the air inside through the climate control system before boarding the vehicle.
Mercedes-Benz Korea is expanding its pure electric vehicle lineup in Korea and providing differentiated experiences to customers. Following the launch of the compact electric sports utility vehicle (SUV) “The New EQA” and the brand’s first luxury electric sedan “The New EQS” last year, the new EQS model and the family electric SUV “The New EQB” are strengthening their electric vehicle portfolio this year.
In the second half of this year, the business electric sedan “The New EQE” and the new EQS will be equipped with a four-wheel-drive system and dual motor, and the New EQS 4504MATIC+, the first electric vehicle of the high-performance brand Mercedes-AMG. Early next year, Mercedes-Benz plans to expand its electric vehicle lineup by introducing its luxury electric SUV “The New EQS SUV” based on its own architecture for electric vehicles.
