In the past two years, the topic of discussion around the Mercedes-Benz brand is power, for example, what A-class/B-class whole 1.3T engine, C-class and future launches The new E-class is also the start of the 1.5T+48V light-hybrid system, and even the next-generation AMG C63 may be a 2.0T four-cylinder engine + hybrid system. In this regard, the response of most people is, Benz dare to fool people so? Mercedes-Benz has no sincerity to reduce power and not price! C63 changed to 2.0T, is this going to surrender to BMW? But when you calm down and think about it, do you think Mercedes-Benz might do such a stupid thing?
So what exactly does Mercedes-Benz do with its product line's powertrain? Just a few days ago, Mercedes-Benz gave a detailed explanation of its vision for its future power system. Many people understand what Mercedes-Benz is going to do. It is not the so-called cost reduction. Mercedes-Benz is actually for environmental protection and emissions, and achieve carbon neutrality of its products. The second is to move towards electrification in a step-by-step transition. In the title of the article, why I said I would like to praise Mercedes-Benz is because these two things show the vision and pattern of a brand. From another perspective, whether it is environmental protection or power electrification, it is already the general trend. It is better to start late than early. This is exactly what Mercedes-Benz intends to do. So while Mercedes-Benz releases its own new electrified power strategy, let's talk about Mercedes-Benz's new power system development vision and some recent controversies involving Mercedes-Benz power system. I believe you will have a new perspective. There is no recharge for this article, it's all on the matter.
Let me talk about why Mercedes-Benz is so "tossing" the power system? The vision for 2039 is the future core of the brand.
Mentioned that Mercedes-Benz has reformed its power system in recent years, and it must start with the concept of Mercedes-Benz-pure electric first. Mercedes-Benz officially released its 2039 vision a while back. From the picture, Mercedes-Benz has taken gradual steps to electrify the power system. First, in 2022, it will achieve carbon neutrality in the vehicles produced by Mercedes-Benz worldwide. By 2030, Mercedes-Benz electric models (including pure electric and hybrid models) will account for 50% of the overall brand passenger car sales, and finally achieve a new carbon neutral passenger car lineup in 2039. It can be seen that Mercedes-Benz is not eager to achieve "electricity first". Now many brands divide traditional gasoline power and pure electric power into two independent parts in terms of research and development. Mercedes-Benz's approach is obvious. At this stage Consumers still have a high demand for traditional gasoline-powered vehicles. First, they integrate the existing gasoline-powered and electrified systems, and the two types of power complement each other. Through continuous technological research and development and accumulation of experience, the final pure electric Models pave the way, this trick is not only safe, but also highly acceptable to consumers.
Before we get to know the layout of the Mercedes-Benz power system, we need to briefly understand the "carbon neutrality" mentioned by Mercedes-Benz. The concept of carbon neutrality involved in the automotive industry is not difficult to understand. We all know that carbon dioxide needs to be produced during the production process of automobiles and the operation of factories. Carbon neutrality means that it needs to be continuously reduced during the production process of vehicles. Carbon emissions (such as the use of renewable energy to generate electricity, etc.), while the products produced should also minimize carbon emissions standards.
So what is the most perfect effect of carbon neutralization? For example, in the production process of vehicles, judging from the current technology, there must be some unavoidable processes that will produce carbon dioxide. Then you should produce vehicles that can produce oxygen in order to achieve true carbon neutrality. Is there any What about car power technology that can produce oxygen? Of course, hydrogen fuel cell vehicles are a typical example. As for the carbon neutrality mentioned by Mercedes-Benz, I don't think it is to be the most perfect in 2039, but to gradually move closer to perfect carbon neutrality. Earlier, I also asked many brands about their imaginations about new energy vehicles, and most of the conclusions I got were that pure electric power is not the end, but fuel cells.
The three power models are two-pronged, 48V light hybrid reduces emissions, plug-in hybrid combines the advantages of gasoline and electrified power, and fully develops and follows pure electric technology
Mercedes-Benz’s "three-step" strategy is divided into three parts, namely EQ BOOST (light hybrid), EQ POWER (plug-in hybrid) and EQ (pure electric) three series, Judging from the current acceptance habits of most consumers for electrification, this gradual transition method is the most secure. Let's talk about the characteristics of these three powers separately.
EQ BOOST-48V volt intelligent motor composed of a light hybrid system, not only reduces emissions, but also improves the vehicle's dynamic response, but also saves fuel.
Let’s talk about the first part of Mercedes-Benz Power’s full electrification-EQ BOOST, which is a common gasoline engine + 48V smart starter motor, such as the current Mercedes-Benz C 260 series, which uses The 1.5T+48V system belongs to EQ BOOST, and the new E-class to be listed in the future has been basically determined. The entry-level model is also equipped with a 1.5T+48V smart motor. This is also a point that many domestic consumers complain about. Then this system Is it really as unbearable as it was posted on the Internet? the answer is negative.
Let's take the Mercedes-Benz C-class as an example. It can be seen that the current C-class with 1.5T+48V smart motor and the old C-class with 2.0T engine have no difference in engine book data. In terms of engine speed, the current engine has a maximum power speed range of 6100rpm and a peak torque speed range of 3000-4000rpm, while the old engine has a maximum speed range of 5500rpm and a peak torque range of 1200-4000rpm. If you look at the speed only, the low-torque performance of the current C-class engine is much worse than that of the old one, but don’t forget, the current C-class starts with an electric motor, and the dynamic response of the vehicle after pressing the accelerator pedal is even better than The old model is better. As for the torque performance of the vehicle after the start, there will be a slight difference from the old model, but to be honest, this difference is almost negligible if it is not reminded by others.
In addition, it must be said that the current C-level 1.5T+48V system has advantages in energy saving and emission reduction, but the old C-level is completely incomparable. First of all, the displacement can be reduced to a certain extent. Fuel consumption and emissions. In addition, we all know that the vehicle is the most fuel-consuming operating condition for the engine when starting, and the current C-class starts with electricity, which further saves fuel + reduces emissions. Compared with the old C-class when the vehicle is accelerating, the difference is obvious. The advantages outweigh the disadvantages, and judging from the actual sales of the cash C-level, there are not many consumers who give up the cash C-level because of the power experience. The new C-level should be sold or sold.
EQ POWER-Plug-in hybrid power is also the powertrain that Mercedes-Benz will be mass-promoting next. The technology developed by EQ POWER on the F1 field will also be gradually applied
After talking about EQ BOOST, let’s take a look at Mercedes-Benz’s next main powertrain-EQ POWER, which is a plug-in hybrid model. The next generation AMG C63 that is transmitted online is exactly With this series, even the 1.6T hybrid system of the Mercedes-Benz F1 belongs to EQ POWER.
In the field of hybrid power, it was actually divided into non-plug-in hybrid and plug-in hybrid at the beginning. The biggest difference between the two is that the non-plug-in hybrid system also integrates a kinetic energy recovery system. It can be charged by itself, and the original plug-in hybrid power system does not support kinetic energy recovery, but only supports external charging port charging, which greatly reduces the practicability of plug-in hybrid models. However, today's plug-in hybrid power system is not what it used to be. It also supports a kinetic energy recovery system. It can also be externally charged or the vehicle can be charged by the excess kinetic energy. Non-plug-in hybrid power has almost no advantages at present. . It is worthwhile to integrate that some domestic purchase-restricted cities have begun to include plug-in hybrid models into the category of new energy models, instantly making plug-in hybrids "scented."
After talking about the development of the industry, let's talk about the convenience that plug-in hybrid models bring to consumers today. PresentIn Mercedes-Benz's plug-in hybrid models, the pure electric cruising range basically exceeds 60 kilometers. Like the new S-class plug-in hybrid models, the pure electric cruising range has reached the level of 100 kilometers. what is this concept? In other words, when commuting in the city, you can't use the fuel engine at all, the motor + battery pack can do it, not to mention the kinetic energy recovery system, which can be charged when the vehicle is braking. You can use the car normally during the day and charge at night. , Or go to work during the day to charge, and use the car at night, basically use no oil, as for long-distance running, just give it to the gasoline engine.
This time Mercedes-Benz also announced some of its latest developments in plug-in hybrid power, and more about the optimization of system operating efficiency. For example, the vehicle will be in pure electric or hybrid at any time according to road conditions. Switch between direct drive and gasoline direct drive to achieve the best fuel efficiency. If you use navigation, the vehicle will analyze urban roads, suburban roads, and highways. For example, pure electricity is used in the city, and gas-electric hybrid is used in the suburbs. The direct drive mode can even be used on high-speed, so that the driver can enjoy The speed-up experience of electric vehicles can also save fuel to the maximum extent, which is definitely a choice with multiple birds.
As for the performance model of the new AMG C63, you really don’t have to worry about the performance of the 2.0T hybrid system, which is not as good as the current 4.0T V8 engine. After all, the C63 is the pillar of the AMG family. Moreover, the promotion of the AMG brand in the past two years has been so great. Various 35, 45, 43, 53, and 63 series "flowers blooming", so there will be surprises at that time, and I expect Mercedes-Benz will also introduce AMG performance cars. Series of plug-in hybrid systems.
EQ-pure electric, focusing on improving the efficiency of the battery pack, while also committed to improving the charging efficiency, Mercedes-Benz EQA is about to release
Finally Let’s take a look at Mercedes-Benz’s EQ series. At present, Mercedes-Benz’s EQ series have EQC. Everyone who has experienced it knows that although the EQC’s cruising range is not the most eye-catching, you will find the details of this car during the experience. The feeling of use is particularly good. Accelerating at full speed will give you a very stimulating feeling of dizziness. At the same time, the dynamic remaining cruising range of the new car is very accurate, and it will not give you the feeling of a false battery. It shows that the difference between the remaining mileage and the actual remaining mileage is very small. As much as you want. For the gradual improvement of detailed technology, it is exactly what the Mercedes-Benz EQ series is doing, such as battery efficiency, charging efficiency, etc. Although it can’t compare with Tesla and other brands in terms of range, at least the Mercedes-Benz EQ series has now detailed details. Partially optimized very well. In addition, from the news released by Mercedes-Benz this time, the next model of the EQ series will be the Mercedes-Benz EQA. This car is likely to be a pure electric version of the new GLA, with a cruising range of 400 kilometers.
The 1.3T engine that everyone talks about has a small displacement but a lot of valuable core technology. A smaller displacement does not mean a cost reduction
In addition to the three series of EQ BOOST, EQ POWER and EQ we mentioned above, Mercedes-Benz has also been committed to carbon neutrality in terms of traditional fuel power. One of the indispensable components is the The 1.3T turbocharged four-cylinder engine, code-named M282, that everyone talks about is also a small displacement but the car is not cheap. Is this engine really just to save costs? The result must not be. When you know the technology used by Mercedes-Benz for this engine, you know that its cost is not lower than the previous 1.6T and 2.0T engines. At the same time, the engine power and operating efficiency are farther than the 1.4T and 1.4T in supermarkets. 1.5T and the 1.6T engine previously equipped with Mercedes-Benz.
Let’s take a more intuitive “chestnut”. The picture above was taken during the Mercedes-Benz night before the Chengdu Auto Show this year. The two cylindrical objects in the picture are the engine cylinder liners, and the one on the left is It is the cylinder liner of the 1.3T engine code-named M282. The one on the right is the cylinder liner of the traditional engine.It can be seen that the cylinder liner of M282 is very thin, only one-tenth of the traditional cylinder liner. The most intuitive feeling for most people is lightweight. At the same time, the M282 cylinder liner uses Mercedes-Benz’s NANOSLIDE nano-level cylinder wall coating technology, which is derived from the AMG 6.2-liter V8 engine, which can greatly reduce engine quality, improve fuel economy and emission performance.
In addition, this 1.3T turbocharged engine code-named M282 is also equipped with Mercedes-Benz’s unique CAMTRONIC variable valve lift technology and intelligent closing technology. The maximum output power of the engine is 120kW/5500rpm and the peak torque is 250Nm/1620. -4000rpm, compared to rivals Audi's 1.4T four-cylinder engine and BMW's 1.5T three-cylinder engine, the book data are better. Therefore, this 1.3T turbocharged engine, code-named M282, is to save costs. This is somewhat absolute. The application of a large number of new technologies can increase costs, and at the same time, on the premise of better emissions and fuel economy. Isn’t that good because it also guarantees power.
is written at the end:
In this era, with the development of technology and the continuous tightening of emission regulations in various countries, traditional fuel-powered vehicles are undergoing great tests, such as BMW and Although Audi also announced its own electrification vision, when it comes to landing, there is still a gap with Mercedes-Benz. Mercedes-Benz is the first to fully enter the era of electrification in the "troika" of German "BBA". Although this kind of innovation will have a certain impact on consumers in the early stage, it is only temporary, because electrification is the general trend. Mercedes-Benz has become a pioneer, so over time, in this part of the electrification field, it will gradually lead other rivals, and even eventually form a technological gap. Regarding the pattern and courage that Mercedes-Benz has shown in the electrification of the power system, I I think it deserves a like, what do you think?
