The editor is very thoughtful
After many countries, including Germany, announced the timetable of banning the sale of fuel vehicles, it is obvious that the electrification of automobiles is the general trend. Compared with BMW iNEXT and Audi e-tron, Mercedes-Benz's pure electric vehicles seem to come quite late.
However, Mercedes-Benz, which started late, is trying to catch up.
"EQC: The Beginning of Electrification Transformation of Mercedes-Benz"
In the second half of 20 19, Mercedes-Benz has announced that it will make major adjustments in the product development route, and all R&D models will continue to be electrified in the future. For specific products, Mercedes-Benz chose to start with SUV models. After all, this is the favorite product type of consumers in China and even around the world, and there is a high probability that there will be no mistake in launching an SUV model. In fact, this is also the unanimous choice of most OEMs.

Although Mercedes-Benz EQC is based on a generation? EQ concept car was built, but it didn't get rid of the shadow of Mercedes-Benz GLC. Therefore, as a brand-initiated model, EQC's overall design lacks innovation and does not leave the author with a stunning feeling in appearance.
Generally speaking, the biggest highlight of Mercedes-Benz EQC is that it is very quiet when driving, and NVH (noise, vibration and shock roughness) is excellent. There is no harsh hum of the motor at low speed, and the wind noise and tire noise at high speed are also well controlled. It can be seen that although EQC has no innovation in the product itself, the luxury of Mercedes-Benz has been passed down as a whole.

However, due to the comfort-oriented adjustment of the vehicle suspension, it is too soft, which makes the vehicle lack of driving pleasure. EQC？ Although the 2.5-ton car body makes the car behave smoothly when accelerating and driving in a straight line, once the speed is too high when turning, it will lead to obvious roll of the car body. In addition, on the bumpy road, due to the heavy body, the rebound of suspension is not crisp enough, and the overall adjustment is soft, which gives users a bad experience.

Generally speaking, Mercedes-Benz EQC gives people the feeling that it is very easy to get started. The overall training of the vehicle is close to that of Mercedes-Benz fuel vehicle, and it has the characteristics of electric vehicle. Especially compared with Audi e-tron, the author thinks that Mercedes-Benz EQC is superior in driving quality and vehicle training. Although the rear space of Mercedes-Benz EQC is relatively compact due to the reason of "changing oil to electricity", the overweight body also leads to the increase of power consumption, which are the key problems that Mercedes-Benz needs to solve. But in general, we can all understand that EQC is a transitional means in the process of electrification transformation of Mercedes-Benz. After all, according to Mercedes-Benz, this is not a hasty response, but one of the planned steps in the process of electrification of Mercedes-Benz brand.
Before the interception of the new car of Audi MEB platform, there was the pursuit of BMW iNEXT. In addition, the progress of Mercedes-Benz in the field of electrification was a bit slow. After all, the company's first pure electric platform model will not be available until 202 1 at the earliest. Therefore, before this, Mercedes-Benz needs to change oil to electricity to test water technology, shorten the research and development cycle, and prepare for quickly seizing the market.
"Three-pronged new energy strategy: EQ? Boost, emotional intelligence? Power and emotional intelligence "
Different from the all-electric "life and death gamble" of Volkswagen, pure electric, hybrid and plug-in hybrid technologies are all included in the planning of Mercedes-Benz's transformation to electrification.
China is now Daimler's largest single market in the world, and we attach great importance to the localized production of electric vehicles. Leng Yan, executive vice president of Daimler Greater China, pointed out, "Before 2022, every model of Mercedes-Benz will have an electric car; By 2030, electric vehicles (including pure electric and plug-in hybrid vehicles) will account for more than 50% of the sales of new passenger cars. "
In order to achieve this goal, Mercedes-Benz has planned a "three-pronged" new energy strategy.
Emotional intelligence? BOOST: stands for electrified internal combustion engine technology, which optimizes the internal combustion engine and reduces fuel consumption and carbon dioxide emissions by carrying a 48-volt intelligent motor.

Take the 2020 Mercedes-Benz C260/C260L as an example. Last year, Mercedes-Benz made a small change to it. Although there seems to be only a small change on the surface, its internal change is revolutionary.
In addition to changing the new M264? 1.5 liter inline four-cylinder turbocharged engine to replace M274? In addition to the 2.0-liter turbocharged engine, EQ supplemented by 48V light mixing was used for the first time. Boost the power system.
Generally speaking, although the engine displacement is reduced, it is reduced by EQ? Boost? 48V？ The comprehensive output power of BSG electric auxiliary motor (in addition to the original 12V lead-acid battery, a 48V lithium battery is added to power the generator and start the motor) is 20N·m higher than that before the transformation.
In addition, the 48V motor provides higher power output than the traditional 12V starting motor, so it can reduce the vibration and noise during engine starting and provide additional torque to make up for the hysteresis response of the internal combustion engine.

Similarly, this technology has also been carried on the brand-new E-class sedan launched at this year's Geneva Motor Show.
Emotional intelligence? Power: stands for plug-in hybrid technology.

19 The new S? 560e？ L this technology has been applied. New s? 560? e？ L's hybrid system consists of a 270kW 3.0L V6 turbocharged gasoline engine and a 90kW motor. In hybrid mode, the comprehensive maximum power can reach 350 kW and the comprehensive maximum torque is 700 Nm. New s? 560? e？ L provides a pure electric cruising range of about 50 kilometers, with comprehensive fuel consumption as low as 2. 1L/ 100km and carbon dioxide emission of only 50 g/km.

Similarly, the new E-class PHEV version launched at the Geneva Motor Show is also equipped with a plug-in hybrid system consisting of a 2.0T engine and motor and a 15.6kWh ternary lithium battery. The maximum comprehensive power is 160kW, the peak torque is 450n·m, and the battery life of NEDC reaches 70km in pure electric mode.

At the same time, there is a brand new CLA? 250e, CLA250eShootingBrake and GLA250e e.
In terms of performance, Mercedes-Benz CLA? The 0- 100km/h acceleration of 250e is 6.8 seconds. Under the working condition of WLTP cycle, its pure electric cruising range is 60-69 kilometers; Mercedes-benz CLA? 250e？ Shoot? The braking is a little slow, and the acceleration of 100 kilometers is 6.9 seconds, and its pure electric cruising range is also reduced to 58-68 kilometers; Mercedes-benz GLA 250 E takes 7. 1 sec to break a hundred meters, and the top speed can reach 220? Km/h, the cruising range of pure electric WLTP is 53-6 1 km.
At this point, in emotional intelligence? In the power part, Mercedes-Benz has successively launched A250e and A250e? Cars, B250e, C300de, E300e, E300de, S560e, GLE350de4Matic and GLC300e4Matic, etc.
EQ: stands for battery/fuel cell technology driven by pure electricity.

According to the analysis of existing news, Mercedes-Benz EQA and EQB will be built based on MEA platform. Mercedes-Benz will provide battery packs with capacities ranging from 60kWh to 1 10kWh, as well as three kinds of motors with different powers, providing maximum power of 150kW, 200kW and 250kW respectively. The car is expected to have a pure electric cruising range of more than 400 kilometers. According to the previous plan, EQA will be unveiled overseas this autumn and is expected to be introduced into China this year.
"From establishing Tengshi through joint venture with BYD to investing and building a factory in China: China New Energy of Mercedes-Benz"
As early as 20 10, Daimler and BYD jointly established Tengshi New Energy, and released the "DENZA Tengshi" brand in 12. Its first model Tengshi 300 was launched on 14, and its batteries were upgraded on 17 and 18 respectively. However, since BYD has been in charge of Tengshi's operation, its brand awareness is not high and its price is not advantageous. In addition, Tengshi's decision-makers did not accurately predict the development direction and market demand of new energy vehicles, which eventually led to unsatisfactory market performance.
However, Tengshi brand plays a vital role in the layout of Mercedes-Benz in China at this stage: because the current electrification technology of Mercedes-Benz is relatively not outstanding, and the complete vehicle products of EQ are not perfect, Mercedes-Benz needs to rely on BYD to achieve its rapid development in this field, so as to consolidate its position in the development of pure electric market in the future. At the same time, in view of the increasingly strict new energy policy in China, Mercedes-Benz also needs a successful model to share the double pressure it faces, and BYD, as the leader of domestic new energy vehicle companies, naturally becomes the first choice for Mercedes-Benz cooperation.
Therefore, Daimler chose to launch a new car Tengshi X based on BYD Tang at the end of 19. I hope to use BYD's mature technology, supplemented by Mercedes-Benz's brand value and design language, to save Tengshi brand's tragic situation before it was in China.
In addition, Mercedes-Benz officially launched the EQ brand at the Paris Motor Show in 16, and then the domestic EQC was officially delivered in 1 19. At the same time, Mercedes-Benz also concentrated on developing PHEV versions of Class A, Class C, Class E and Class S. ..
It can be seen that Daimler quickly adjusted its strategic layout according to the changes of trends and policies, especially in China.
Last year, BAIC and Daimler invested10 billion yuan to build a new factory of Beijing Benz, which is located in the original Shunyi production base of BAIC SICB. The two sides upgraded the base only to realize the localization of Mercedes-Benz electric vehicles as soon as possible. At the same time, in order to provide sufficient protection for domestic Mercedes-Benz electric vehicles, Mercedes-Benz chose to set up the first power battery factory outside Germany in Beijing. Marcus Schaefer, director of Mercedes-Benz Automotive Group, said earlier: "The establishment of a luxury electric vehicle power battery factory in China is an important step in the strategic layout of Daimler's electric vehicles, which is very important for flexibly and effectively meeting the needs of China customers for pure electric vehicles."
However, Mercedes-Benz was not smooth sailing in the process of electrification transformation. Earlier, it was reported that in the North American market, due to the battery shortage of LG Chemical Company, Mercedes-Benz had hoped to sell 25,000 EQCs in 19, but only 7,000 were produced in the end. And the source of all this is because Tesla acquired Grohmann? Engineering, leading to Daimler battery manufacturer Germany? The battery capacity produced by Accumotive is insufficient in supply and demand. Before that, Mercedes-Benz was Grohmann? It was Grohmann who helped build battery modules and battery production lines for customers of Engineering and German Power Battery Factory. Finally, due to the production capacity problem, the time for Mercedes-Benz EQC to enter North America will be postponed to 202 1 year.
In order to prevent the accident from happening again, Daimler signed a battery supply contract with Contemporary Ampere Technology Co., Ltd. in May last year. However, according to the internal information obtained by the Chief Travel Officer, at present, suppliers can never guarantee a stable battery supply, and the battery factory built by Mercedes-Benz can never guarantee sufficient battery capacity. This means that the production capacity of Mercedes-Benz EQ series electric vehicles will also be limited in the future.
Generally speaking, whether Mercedes-Benz EQC, the first pure electric SUV of Mercedes-Benz, was officially launched in China, or a new generation of Tengshi pure electric and plug-in hybrid SUV was launched during the Guangzhou Auto Show, or 48V light-mixed new Mercedes-Benz E-Class and new PHEV models were unveiled at the Geneva Auto Show, it is not difficult to see that Daimler has accelerated the pace of electrification in China. However, if the problem of battery supply cannot be solved all the time, its electric vehicle sales will be greatly affected in the future.
