　　[Autohome professional evaluation] Not long ago, the 2021 model (|) was officially launched in China. We thought this was another era change that only fine-tuned the configuration price. After carefully comparing the parameter table, we found that the manufacturer had quietly replaced the GLE 450 with a new 2.5T engine. Although it is still an inline 6-cylinder, what is the reason for the lack of this 0.5L displacement? Does it affect the power? To this end, we specially got the new test drive car and tested it. Through the test results, we will answer your doubts.

What impact will the launch of the new model have on consumers?

　　The 2021 Mercedes-Benz GLE first adjusted the prices of some models, reducing the prices of the GLE 350 dynamic, GLE 450 dynamic and GLE 450 fashion models by 15,000, 35,000 and 9,000 yuan respectively. According to the latest vehicle and vessel tax regulations, the new GLE 450 models, due to the reduction in displacement, the vehicle and vessel tax will be reduced by nearly half compared with the 2020 GLE 450.

　　As the top model of the GLE 450 4MATIC luxury model, while the price remains unchanged, in addition to replacing the new engine, the 2021 model only adds the remote OTA and rear multimedia control functions of the car, which is relatively small. Therefore, our test mainly focuses on the changes brought about by the new power.

◆ Power feeling:

　　First of all, let’s talk about this engine. Since the information revealed by this engine is quite limited, and there is no GLE model equipped with this engine overseas, its existence seems somewhat mysterious. The nameplate shows that the engine is codenamed "M256 925". Compared with the 3.0T engine codenamed "M256 930", it is easy to see that these two engines belong to the sibling relationship between the same series, and the suffix "25" number also corresponds to the displacement of 2498mL. According to our previous understanding of modern engines, the difference in displacement between the two engines is most likely achieved by replacing the connecting rods and crankshafts of the new specification. Such changes are usually reflected in the power data and power output style. However, the power data of this new engine is on par with the previous 3.0T engine, the difference only existing in the narrower output speed range, which is more or less surprising.

　　The 2.5T engine has all the advantages of the previous 3.0T engine, and has been carefully built under the dual concept of modularity and electrification from beginning to end. The water pump and air-conditioning compressor no longer need to be driven by a belt, so that the engine can be carried lightly. With a smaller size and more powerful integrated 48V start motor, it can adapt to the needs of frequent starts and stops as much as possible. The combination of "electronic turbine + exhaust gas turbine" well solves the problem of insufficient low inertia stamina and obvious hysteresis of large inertia turbines. In addition, the inspired integrated electric motor with a coaxial design between the engine and the gearbox can also provide an additional driving force of about 21 horsepower to play the role of power connection and kinetic energy recovery, and cooperate with the coasting function to play the purpose of fuel saving.

　　Although the new engine has narrowed the speed range corresponding to the maximum horsepower and maximum torque in terms of parameters, in actual driving, even if you stare at the meter to feel it, you still can’t feel any difference between it and 3.0T. The influence of the traditional internal combustion engine "bore × stroke" setting on the output characteristics has become blurred. In short, the whole set of power still feels like a strong low-speed torque and a rich power reserve at high revolutions.

　　Although BMW’s ZF 8AT is compared with Mercedes-Benz’s 9AT every time, the conclusion is that the former is slightly better than the latter in all aspects, but in fact, after the introduction of 48V motors, this gap has almost reached the level of insignificance.

　　During the test, I have repeatedly given the throttle a "sudden attack on the old comrade" after stopping. As a result, the start-stop function can wake up the power at the first time, and it can drag the vehicle away in a straight-line acceleration performance without any hesitation, as if the engine has never stopped working.

◆ 0-100km/h acceleration test

　　The starting speed in place is still limited to the range of 2400rpm, and the power combination is very fast at the beginning, unlike some models equipped with dual-clutch transmissions. With the help of the OurHours four-wheel drive system, it is even more difficult to experience wheel skidding.

　　The acceleration of 6.25s was only 0.3s slower than before, and there was no difference in the general human body. Compared with the main competitors of the same level, its acceleration score still belonged to the same echelon.

◆ Fuel consumption test:

　　The whole test was carried out in ECO mode with the air conditioner turned off. The fuel consumption of 8.6L/100km is really an excellent result for a medium and large SUV weighing more than 2 tons and OurHours four-wheel drive. Compared with the previous model equipped with 3.0T engine, the fuel consumption performance is also significantly reduced. It can be said that this new power system combining 48V hybrid technology strikes a new balance between power and fuel economy.

In the past two years of auto shows, it can be clearly found that new energy vehicles have become the "sweet cake" at major auto shows. If there are no bright new energy products, they will be eclipsed at auto shows, and traditional fuel vehicles will become unnoticed. At the Beijing Auto Show in the first half of the year, Xiaomi Auto became the top of the Beijing Auto Show due to its first participation in the auto show and Lei Jun’s personal presence.

At the upcoming Chengdu Auto Show, although the specific participating new cars have not yet been fully announced, there are not many new cars that have been confirmed to be launched at the Chengdu Auto Show, and they are all very topical new products. So, what other blockbuster new cars will be released at this year’s Chengdu Auto Show?

XPeng MONA M03

As early as at the Beijing Auto Show in April, it was rumored that the car would make its debut, but in the end, everyone knew that the car did not make its debut at the Beijing Auto Show, but made its official debut through online live broadcast in July. At present, the Xiaopeng MONA M03 has arrived at the store one after another, and the outside world has been well aware of the specific design and configuration of the new car.

At present, Xiaopeng MONA M03 has opened reservations and plans to be officially launched on the eve of the Chengdu Auto Show. Most of the speculations about its price will start within 150,000 yuan or even lower. Considering the positioning of Xiaopeng MONA M03 compact car, the possibility of pricing within 150,000 yuan is still very high.

From the core parameters, the Xiaopeng MONA M03 is all driven by a single motor, but it is also divided into two versions of high and low power, 140kW and 160kW respectively. In terms of battery life, the low-end model has a pure electric battery life of 515km under CLTC conditions, and the high-end model has a battery life of 620km. This battery life performance is also relatively good among pure electric cars around 15.

It is worth mentioning that the Xiaopeng MONA M03 is not equipped with a lidar, which means that the intelligent driving assistance of the vehicle will adopt a purely visual solution. All models are equipped with 7 cameras, 12 ultrasonic radars, and 2 millimeter-wave radars. Intelligent driving and smart cockpit will be the core competitiveness of the Xiaopeng MONA M03, and its performance is worth looking forward to.

Avita 07

As a product of the strong alliance of Changan, Huawei, and Ningde Times, Avita has also been able to fight in the high-end market, and the existing and both are well-known in the high-end market. At this year’s Chengdu Auto Show, Avita will also bring its third model -.

In terms of positioning, Avita 07 is lower than Avita 11 and is a medium-sized SUV, which means that Avita 07 will be lower in price, and the current starting price of Avita 11 is 300,000 yuan, so the price of Avita 07 must be within 300,000 yuan. More importantly, Avita 07 also provides the choice of extended-range models. This is also the first time that Avita brand has launched an extended-range model. The arrival of the extended-range model will further explore the starting cost of Avita 07, so the outside world has long been looking forward to Avita 07.

In addition, it can also be seen in the previous MIIT declaration information that Avita 07 is also equipped with lidar, which means that the new car will also support Huawei’s high-end intelligent driving assistance, which can realize the high-speed + city piloting smart driving function. However, since Avita 11 and Avita 12 are three lidars, while Avita 07 is a single lidar, it is not yet known whether its smart driving experience will be different.

Zhijie R7

In Huawei Hongmeng Zhixing system, compared to Wenjie, Zhijie’s influence is obviously much lower. Even if the first model has received a certain number of orders through the secondary listing, it is still far from the performance of Wenjie. Enriching the product matrix has also become the top priority of Zhijie. At this year’s Chengdu Auto Show, Zhijie will also bring its second mass-produced model -. Unlike the existing Zhijie S, the Zhijie R7 will be a medium-sized SUV.

From the information available so far, the Smart R7 is designed with a similar design language to the Smart S7. At the same time, it can be seen on the side that it adopts a crossover coupe SUV style, and its visual effect is quite a flavor. At the same time, the rear is also designed with a hatchback tailgate to enhance the practicality of the vehicle.

In terms of size, the length, width and height of the Smart R7 are 4956/1981/1634mm respectively, and the wheelbase is 2950mm, which is very obvious compared to Tesla. More importantly, it is reported that the Smart R7 will also use Huawei Tuling chassis, which not only has a suspension combination of front double fork arms + rear five links, but also will be equipped with smart air suspension and CDC variable damping shock absorber. As for the latest ADS 3.0 high-end intelligent driving assistance, it will naturally not be absent on the Smart R7, which also makes the outside world have more expectations for the Smart R7.

BYD Seal X

As the best-selling car brand in China, BYD is still expanding its product matrix. Although this year’s BYD mainly upgrades existing models, it does not build new models as frequently as in previous years. But at this year’s Chengdu Auto Show, BYD will also bring a new model – X.

From the name, the SEAL 06 X is a derivative of BYD SEAL. In fact, the SEAL X has little to do with the existing BYD SEAL. The current BYD SEAL has been derived into a series, including SEAL, SEAL 06 DM-i, SEAL 07 DM-i and the latest SEAL X. It is worth mentioning that the new car has multiple names including SEAL 06 GT, SEAL, SEAL 05 EV and SEAL X. The specific name will have to wait until the Chengdu Auto Show to reveal.

In terms of design, the Seal X continues the minimalist and sporty style of the marine net family, with a closed grille and bold lower enclosure on the front face, and a through heat dissipation opening on the front enclosure, giving the vehicle a strong sporty atmosphere. The tail is equipped with a large-size tail and a through taillight group, and the bottom diffuser and ventilation slot optimize the aerodynamic characteristics, making the Altitude X a pure electric small steel cannon.

Since it is a small steel cannon, it will naturally not be weak in terms of power performance. According to MIIT’s declaration information, BYD Seal X will provide two options: single motor and dual motor. The maximum power of the single motor rear drive model is 160kW and 165kW. The AC asynchronous motor with the front motor of the version is 110kW, and the permanent magnet synchronous motor with the rear motor is 200kW, making the total power of the motor reach an amazing 310kW. Zero hundred acceleration is worth looking forward to.

Write at the end:

The above four new energy vehicles are all new models that will be unveiled at the Chengdu Auto Show, and they all have their own product highlights, which will definitely attract wide attention at the Chengdu Auto Show. In addition, there will be more new models launched at this Chengdu Auto Show, and the car wheel will continue to pay attention.

　The China Light Industry Federation organized a scientific and technological achievement appraisal meeting in Wuhan, Hubei Province, which was jointly completed by Xiaomi Technology (Wuhan) Co., Ltd. and many other units, including "Research and Application of Key Technologies of Internet Air Conditioning Inverter Based on Full-Link OTA Technology" and "Research and Application of Key Technologies of Household Air Conditioning Energy Conservation and Health Based on Internet Thinking".

Shan Lianyu, general manager of Xiaomi Air Conditioning, delivered a speech and introduced the current situation of technical development. Technical representatives Wu Junhong, Peng Guangqian, and Li Chao made a detailed project report to the experts of the appraisal committee and organized a live demonstration of the prototype. After inquiry and discussion, the experts of the appraisal committee agreed that the technical achievements of the two projects were innovative and reached the international leading level, leading the intelligent development of air conditioning technology.

Based on the research and application of key technologies of Internet air conditioner frequency conversion based on full-link OTA technology, Xiaomi has proposed three innovative technologies: "Intelligent networked air conditioner full-link high-efficiency OTA upgrade technology", "Internet air conditioner intelligent parameter matching and intelligent after-sales services technology", and "Extreme speed temperature control and wide temperature domain frequency conversion control technology".

The first application of full-link, high-efficiency OTA upgrade technology in intelligent networked air-conditioning products has achieved a stable, efficient and reliable upgrade of air-conditioning internal and external units, endowing air-conditioning equipment with the ability to continuously evolve.

Invented multi-scene adaptive high-speed temperature control and wide temperature domain frequency conversion control technology, and comprehensively applied load forecasting, transient start, double speed high frequency and full temperature domain pulse adaptive suppression technology to achieve rapid cold/heat input and reliable operation under extreme ambient temperature.

The full-link OTA technology can be understood as the core of the continuous evolution of intelligent air conditioners. Xiaomi adopts a single-channel multi-target, multi-partition, configurable combination upgrade strategy, and a high-speed communication circuit design to achieve full-link OTA for air-conditioning displays, internal electronic control boards, and external electronic control boards, which undoubtedly lays the foundation for the future development of intelligent air conditioners.

Research and application of key technologies for energy saving and health of household air conditioners based on Internet thinking, Xiaomi proposes three innovative technologies: "Air conditioner energy saving control technology based on IoT technology for customized and comfortable operation", "Clean air outlet technology based on modular dust removal and dual heat source pulsation sterilization" and "User environment custom control technology based on intelligent interaction".

The first energy-saving control strategy for customized and comfortable air conditioners based on IoT technology has achieved targeted temperature control in personnel activity areas and anti-excessive dehumidification during cooling and cooling, which has greatly improved the comfort of air conditioners, and at the same time achieved energy-saving and low-carbon operation, effectively reducing the energy consumption of household air conditioners and reducing consumers’ daily expenses.

Based on the clean air outlet technology of modular dust removal and dual heat source pulsation sterilization, the dust removal module can be used in multiple air conditioners and high temperature sterilization of the whole air duct of the internal machine, which greatly improves the air outlet quality of the air conditioner.

The user-defined air-conditioning control technology based on smartphone interaction can customize the use area of different rooms or intelligently detect the area of the house on the APP side, automatically correct and control the frequency range and FM speed in the early stage of air-conditioning operation, and adaptively adjust the output range of the ability. And one-click to turn on the overload scene ability to output the MAX mode very quickly to maximize the circulating air volume and cold and heat output.

Xiaomi not only achieved breakthrough technical achievements in the field of intelligence, but also continued to make efforts in the safety and quality of air conditioners. On April 18, CVC Weikai joined hands to win the bidding of Energy Efficiency Technology (Beijing) Co., Ltd. to jointly release four types of electronic and electrical products such as room air conditioners. "Double safety standard certification", Xiaomi was the first to be certified!

Compared with the well-known 3C certification, the evaluation of the dual safety standard certification is more stringent, which can further ensure the safety experience of the product and effectively reduce the occurrence of accidents. Obtaining the industry’s high-standard dual safety standard certification fully proves that Xiaomi takes the quality of air-conditioning products seriously and always puts Quality Standard first. No matter the appearance material, internal materials, and core components are all high standards and strict requirements, consumers can buy with confidence.

In addition, Xiaomi has also obtained the first-class product certification in the air-conditioning performance grading certification under the guidance of the China Household Electrical Appliances Research Institute and undertaken by the Chinese Academy. The new first-class of the giant power-saving large company can obtain this honor, which fully reflects its excellent quality.

Xiaomi has not only benchmarked first-class traditional air-conditioning companies in safety and quality, but also won industry recognition. It has made key breakthroughs in the field of intelligence and led the future development direction of intelligent air-conditioning. Xiaomi is promoting the intelligent innovation of air-conditioning with self-developed technology, and continues to deepen from intelligent experience to intelligent technology.
