[Aika Car Bicycle Test Original]
In the early morning, everything was silent, and the surroundings were not so real. With a low roar, the V12 engine woke up from its slumber and propelled the Stuttgart flagship slowly forward. The three-pointed star emblem stands at the front of the car, shimmering with subtle light against the light of the boulevard. Turning around the island, the Mercedes-Benz S-Class finally enters the Autobahn Highway and begins a cruise feast with German characteristics. The sound of Berlin plays a melodious melody, and the magic carpet suspension keeps the road impact out of the car, making people forget the speed of more than 200km/h. Aside from porsches eager to release and skoda, which is tired of hurrying, few cars have passed by the side.
Jingle Bells, dream woke up.
The new "Brick Moving Day" begins. Unfortunately, what awaited me was not Autobahn, but the "red and purple" imperial morning peak. At this moment, I have no interest in the S-Class, I just want to have a quiet electric car. Times have changed, competition is especially true, and bosses' money bags cannot be handed over to people. In response to the call of the times, Stuttgart people have created a new pure electric flagship - Mercedes-Benz EQS.
In recent years, Mercedes-Benz has opened up and closed its doors in design, fully stimulating the vitality of innovation. Rumor has it that EQS is a perfect copy of Mercedes-Benz Chief Design Officer Gordon Wagner's original vision of the EQ flagship sedan. From the F700 concept car to the Vision EQS to the EQS production car, it is not difficult to see Mercedes-Benz's forward-looking thinking on future travel.
Frankly speaking, the Mercedes-Benz EQS has caused great controversy in the automotive circle, with some people willing to accept epoch-making design innovations and others expressing puzzlement about its jumping thinking. To be sure, EQS, with its new design language, has made engineering breakthroughs that were previously unattainable. Taking the wind resistance coefficient as an example, EQS achieved the industry benchmark of 0.20, and the angular BMW i7 stopped at 0.24. In a rigorous and stubborn German culture, EQS's design-driven engineering approach is undoubtedly an important breakthrough.
Bring the concept car into reality
Unlike the conservative German compatriots, Mercedes-Benz resolutely stood at the forefront of the automotive industry and completed the design revolution from the outside in. As the flagship sedan of Mercedes-EQ, the Mercedes-Benz EQS has pioneered a new interior concept, playing a new trick with the already commonplace triple screen. EQS uses actions to tell people that solemnity is luxury, and cutting-edge technology is also luxurious.
Worldwide, the Mercedes-Benz EQS offers only one body solution (wheelbase 3210mm), without distinguishing between standard wheelbase and long wheelbase versions. Interestingly, Mercedes-Benz gave the EQS the chassis number V297. Readers familiar with Mercedes-Benz must know that "W" stands for the standard shaft and "V" stands for the long shaft. It is not difficult to see that even the very coupe-style EQS has not ignored the rear space.
In the Chinese market, Mercedes-Benz EQS offers three types of rear seats, namely the base seat (non-adjustable), the rear seat assembly (electric adjustment) and the multi-profile rear seat (electric adjustment/dynamic compensation). The test vehicle was equipped with a rear seat component worth 15,000 yuan, but the seat cushion design was not perfect, and there was still a certain gap between the ride and the ride feeling was 100% relaxed. For car owners, the front row is the right way to open the EQS.
The front row is the main seat
So far, the Mercedes-Benz EQS series is equipped with a 111.8kWh battery pack and is available in 450+ and 580 4MATIC power specifications. Among them, the EQS 450+ is equipped with a rear single motor, and the EQS 580 4MATIC is equipped with dual front and rear motors, which realizes the electric four-wheel drive. Due to wheel and weight differences, the entry-level model (EQS 450+ Pioneer Edition) has the lowest energy consumption in the series, and the 849km CLTC cruising range is almost at the ceiling level of a production car.
From EQC to EQA, EQB, and then to today's EQS, the Mercedes-EQ family gradually transitioned from AC asynchronous motors to permanent magnet synchronous motors. Permanent magnet synchronous motors have higher power density and advantages in terms of volume, reducing the difficulty of space layout. In addition, permanent magnet synchronous motors theoretically have lower energy consumption and contribute a lot to endurance performance.
EQS uses ternary lithium batteries, the battery pack consists of 12 modules, and the capacity of a single module is in the early 9kWh head. The battery cell formulation uses a more aggressive "8 series" scheme, namely NCM811, which results in higher energy density. However, the relatively limited increase in energy density makes it difficult to offset the weight drawbacks of large-capacity battery packs. The EQS 450+ Deluxe Edition has a curb weight of 2530 kg, an increase of more than 300 kg compared to the S 450 L of the same power level.
If the story ends here, then EQS is nothing more than an S-rated replica. Switch to sport mode, step on the acceleration pedal deeply, the torque bursts instantly, and the power response is as fast as lightning, which makes people can't help but sigh the beauty of the electric car. In the face of the complex road conditions on the streets of Beijing, the power response is far more important than the limit output. When stitching in traffic, even the AMG S 65 L is unlikely to match the EQS 450+, which has a much lower "keyboard value".
After actual measurement, the EQS 450+ delivered excellent answers, and the four noise performances were far ahead of the recommended value of Aika. The rhetoric is unfounded, and the data is the most convincing. After testing, the EQS 450+ has a 120km/h driving noise of only 63.5 decibels, which is the best result we have tested of all pure electric vehicles. It's not hard to imagine how the EQS 580 4MATIC, with its double-layer acoustic glass, performs.
In terms of comfort, the Mercedes-Benz S-Class has its own way of expressing itself, and now the EQS has inherited a good pedigree. Without the roar of the engine, the tire resonance is easily noticed by passengers. To this end, Mercedes-Benz and Goodyear jointly developed the EAGLE F1 ASYMMETRIC 3 tire and improved the rubber formulation for the characteristics of electric vehicles.
When Mercedes-Benz builds its flagship with care, the results are usually not disappointing. In terms of driving, EQS is like the S class in electric vehicles, and quiet and comfortable are its advantages. Unlike the S-Class, the EQS has an agile dynamic response, setbacks disappear without a trace, and daily walking is very smooth. In urban scenarios, EQS is more "S(super)" than S-class.
It opens better than the S-class
◆ Accelerate testing
The EQS 450+ puts battery life performance first, and the acceleration performance is relatively flat. In field tests, the EQS 450+ Deluxe Edition achieved a 0-100km/h acceleration of 6.04 seconds, and the power performance was in line with expectations. During the acceleration, the body posture is very calm, and the pitch is controlled at a very low level. Moving quickly in the calm of the wind and waves is the fundamental pursuit of EQ flagship.
In the acceleration session, the EQS 450+ had a gratifying performance, which was comparable to the S 500 L 4MATIC that we had previously tested. Specifically, the acceleration time of 40-80km/h is 2.34 seconds, and the acceleration time of 80-120km/h is 3.86 seconds. Coupled with the swift power response, overtaking within the legal speed limit is handy.
◆ Brake test
The EQS 450+ is equipped with low roll resistance comfort tires that offer inherent advantages in endurance performance and filtering. However, relatively weak tire grip constrains braking performance. After testing, the car's best 100-0km/h brakes were 39.61m. In the continuous test, the curb weight of more than 2.5 tons caused a severe test on the braking system, and there was a certain thermal attenuation of the braking performance.
◆ Winding pile test
With a body length of more than 5.2m and a curb weight of more than 2.5 tons, the Mercedes-Benz EQS sounds like it has nothing to do with sports. However, in the pile winding test, the handling of the car was eye-catching. With the low center of gravity brought by the battery pack, the EQS compensates well for the weight disadvantage, and the roll control and steering response are satisfactory. Fast-moving between pile barrels, the EQS is as agile as a sporty mid-size car.
Overall, the Mercedes-Benz EQS strikes a high level of balance between sport and comfort. In the traffic flow "drilling", the EQS is even more flexible than the mainstream medium and large cars. EQS proves with strength that body size is no excuse for handling bulky. Banknote ability, it is so wonderful.
Editor's Comments:
In the face of the trend of electrification sweeping the world, the German Troika has given different solutions to the problem. BMW uses the existing architecture to create fuel, plug-in hybrid and pure electric models at the same time, which inevitably makes people think of "oil to electricity". Audi's transformation of pure electricity is the most resolute, but it has suffered the loss of the product cycle, and the PPE platform has not been put into mass production. So far, Mercedes-Benz is the one that has gone the furthest. Entering the age of electricity, the inventors of the automobile wanted to be the first to take the lead and redefine luxury.
Returning to the product itself, the Mercedes-Benz EQS shows the deep heritage of the Tri-Star flagship, and the driving performance is as good as the S-class. Unlike the S-Class, the EQS has a trendy look and a forward-looking cabin, and the external image has undergone earth-shaking changes. For young upstarts, EQS fully highlights the personality and injects a new character background into the Trident Star flagship. Without quotation marks, EQS is a true youth version of the S-Class. In China, the average age of S-class users is 39 years old. Guess how much EQS will refresh this number?
