Since 1886, when Carl Benz invented the world's first three-wheeled car, the name of Mercedes-Benz and the three-pronged star logo have been deeply imprinted in people's minds, whether it is design or technology, Mercedes-Benz has been influenced by the style of the vane for more than a hundred years and promoted the development of the automobile industry. On the new track of new energy, Mercedes-Benz officially launched the Mercedes-Benz EQS in December last year to meet the challenges of new car-making forces, and how does this electric vehicle, which is known as the flagship, really perform? Let's talk about the content of this review in detail.
First, the performance test part:
Test model: Mercedes-Benz EQS 450+ Deluxe Edition (hereinafter referred to as Mercedes-Benz EQS)
Official guidance price: 1.1936 million yuan
100 km/h acceleration (0-100 km/h):
Test Method:
Turn off the ESP, turn off the electrical equipment such as air conditioners, adjust the mode to Sport mode, and start the ejection.
In the actual test process, the 0-100 km/h acceleration time of the evaluated model is 6.58s, which is slightly slower than the officially calibrated 6.4s 100 km/h acceleration time. Considering that there is a slight dust on the test road on the day of the test, it may affect the grip performance of the tire, so this performance is also expected.
For the Single Motor Mercedes-Benz EQS, such an achievement is also expected, after all, the single-motor model is not known for its eye-catching acceleration performance, if you want to accelerate faster than 6.58s, you can choose the dual-motor power version of the top model.
Braking distance 100-0km/h:
Test method: When the speed reaches 100km/h, the braking distance of the whole vehicle is tested by means of instantaneous braking with high force.
On the brakes of 100-0 km/h, the evaluated model delivered a brake performance of 36.03 m. Since the single-speed transmission does not involve deceleration and downshifting, the Mercedes-Benz EQS under strong braking has a high degree of smoothness. The braking performance of 36.03m is the best in the same class.
Test of charging time and charging cost
According to the different number of drive motors, Mercedes-Benz EQS is divided into single motor and dual motor power version in terms of power, of which the top model is front and rear dual motors, and on the model of this review, it is equipped with a rear permanent magnet synchronous motor, with a maximum power of 245kW and a maximum torque of 568N·m. On the Mercedes-Benz EQS, the whole series is equipped with ternary lithium batteries, and its battery capacity is 111.8kWh.
In terms of charging, we have chosen the State Grid DC charging pile, which is widely used at this stage.
(The remaining mileage displayed by the vehicle before charging is 120km, and the remaining battery is 15%).
In the whole DC fast charging process, the peak voltage of the charging pile is 406.2V, and the peak current is stable at 101.50A, which is converted to a peak power of 41.23kW. (The power of charging piles will vary in different regions)
(Charge up to 80%, the remaining endurance is 645km)
From a battery life of only 120km until the battery is charged to 80%, the battery life shows that the remaining cruising range is 645km, the total time is 1 hour, 58 minutes and 23 seconds, and the total cost including service fees is 114.43 yuan.
Charging Summary:
After in-depth experience of the Mercedes-Benz EQS charging process, there are the following points I would like to share with you:
The power of our DC fast charging pile (peak power is 41.23kW) is actually not very large in the fast charging pile, so under the action of the higher power charging pile, the overall charging speed of Mercedes-Benz EQS will be further improved on this basis.
Overall, the DC charging cost of 114.43 yuan is actually not expensive. However, because many DC charging piles in Beijing are designed in large shopping malls, high-end office buildings and some internal parking lots, in many cases, it is necessary to add parking fees to the charging cost.
Mercedes-Benz EQS compared to the previous I have tested and even most of the models on the market battery capacity is more, 111.8kWh battery capacity under the same conditions, charging time is indeed slightly longer than more models, but the mileage is also more solid, which is understandable.
Third, the mileage test
Overnight mileage power loss
When: Beijing in early April
Temperature: 15°-3°
The test took the form of a power outage and placed the Mercedes-Benz EQS outdoors overnight to test the effect of low temperature conditions on the power at night. As shown in the figure above, before the power is cut off, the remaining mileage shown is 400km.
(Pictured: After the vehicle is started the next day, the remaining mileage shown is 394km)
From the above figure, we can see that the vehicle is placed overnight for more than 12 hours (18:04 at night to 8:16 the next day), and after starting the vehicle the next day, the remaining mileage shown in the table is 394km, and the difference between the two is 6km.
From this test, we can see that in the context of the temperature is not particularly low, the consumption of the mileage of the overnight storage vehicle is not large.
Range test
Mileage test conditions:
The test section is an urban section (50%) + a high-speed section (50%), and there is no intense driving situation throughout the whole process.
The test site is Beijing in early April, and the maximum temperature is maintained at about 15 °C, and the minimum temperature is about 3%.
The range test took 2 days and was not done all at once (leave the car outdoors at night).
Occasionally turn on the air conditioner during the test and turn on the music throughout.
From the above two figures, we can see that the remaining mileage displayed in the LCD dashboard at this time is 464km, the actual mileage after the vehicle was charged last time is 271.7km, and the table shows that the mileage consumption is 307km. The difference between the actual mileage consumption and the meter consumption mileage is only 35.3km, and the difference between the "ideal" and "realistic" endurance performance is not large, and in the new energy vehicles, it is really not easy to find. I am also convinced that if the test is completed in one go under ideal conditions, the Mercedes-Benz EQS can have a better battery life than this.
From the objective factor point of view, the weather conditions of this test are indeed conducive to the performance of pure electric vehicles running for long endurance. However, in the case of occasionally turning on the air conditioner and turning on the music throughout the process, mercedes-benz EQS can maintain such a real power loss, which is indeed rare, which shows the skill of Mercedes-Benz in "three electricity" technology.
About Autonomous Driving Assistance:
In the era of automatic driving assistance, There is still a gap between the high-end automatic driving assistance capabilities of Mercedes-Benz EQS compared with brand models such as Tesla, Xiaopeng and Nippon at this stage. Of course, we also know that for some of the above models of high-end automatic driving assistance is also a costly option. However, only from the perspective of the basic automatic driving assistance function at this stage, Mercedes-Benz EQS is still worthy of recognition. Under the joint action of HUD and navigation, it gives it a better performance.
In addition to the adaptive cruise and automatic car driving that we most commonly use, the Mercedes-Benz EQS gives me the deepest impression from the following two points:
First of all, the performance of lane centering is very solid, the vehicle can be firmly maintained in the center of the lane according to the route on both sides (the realization of the road surface and the dotted line can be clearly distinguished), even if it is a high-speed ramp, this powerful system can give the driver enough confidence to hand over the vehicle to this automatic driving assistance system. Secondly, as mentioned above, the vehicle can clearly distinguish the realization of the road surface and the dotted line, and after the toggle steering, the vehicle will automatically change lanes according to the road conditions on the steering side.
In addition, the built-in map information and design of mercedes-benz machine is quite comprehensive, after searching for destinations through car navigation, Mercedes-Benz EQS will combine HUD, central control display screen to guide the driver. Although this system cannot be linked with Mercedes-Benz's automatic driving assistance at this stage, and it can change lanes according to navigation, it also has a high auxiliary effect on successfully reaching the destination.
About rear wheel steering
The Mercedes-Benz EQS has a body size of 5227mm/1926mm/1513mm, which is also biased towards the top category in the field of large cars. Only from the 5227mm body length and 3210mm wheelbase size to analyze, such a long body size, can not help but make people "turn, U-turn inconvenient" thinking.
Rear wheel steering on the Mercedes-Benz EQS, where the standard rear wheel steering angle of up to 4.5 degrees, improves the handling and dynamics of the new EQS. For vehicles produced from 2022 onwards, users can opt for rear steering with a steering angle of up to 10 degrees, or activate them later via OTA remote online upgrades. With this option, the Mercedes-Benz EQS will achieve a turning diameter of 10.9 meters.
What is the concept of a turning diameter of 10.9 meters? For a simple example, for the average compact sedan, their turning diameter is between 10 and 12 meters. As a large car with a length of 5227mm, the Mercedes-Benz EQS can hand over the result of 10.9 meters of turning diameter, which is enough to see the help of its rear wheel steering technology for the Mercedes-Benz EQS.
#写在最后
Judging from the various projects in this test, the Mercedes-Benz EQS, as the flagship model in the new energy track of Mercedes-Benz at this stage, does not blindly pursue high-performance performance like many, nor does it match how high the automatic driving ability is. However, from its more solid and longer endurance, better understanding of consumers' demand for luxury and the long-term accumulation of brand influence, this model is still a good choice for luxury brand pure electric vehicles. In the future, we will bring you a detailed static analysis of urban roads and new cars, so stay tuned.
