A few days ago, we learned from the official that the new rear-drive version is on pre-sale, and the pre-sale price of the new car is 928,000 yuan. As an entry-level model, this car adopts the form of rear-wheel drive. In appearance, the new car and Taycan 4 maintain the same height, and there is no special change because it is an entry-level model.

The front of the new car looks flat, which is also Porsche’s consistent design style. There are also diversion grooves on both sides, which has a good sense of movement. The charging port of the new car is designed on the right front fender, and the semi-hidden door handle and the dynamic shape of the back are still Porsche’s appearance. The through rear taillights add a sense of hierarchy to the tail.

In terms of configuration, the new car comes standard with Porsche Sport Chrono components, BOSE surround sound system, comfortable entry and parking assistance system with panoramic images. Localized software such as QQ Music is integrated into the car system, and CarPlay is deeply integrated into the display screen and various functions. The dual-chamber dual-valve adaptive air suspension is also standard.

In terms of power, this entry-level model is equipped with a single motor, with a maximum horsepower of 408Ps, a 0-100km/h acceleration of 4.8 seconds, a maximum speed of 230km/h, an energy recovery power of 400kW, and a maximum cruising range of 604km under CLTC comprehensive operating conditions.

With the popularization of cloud computing, big data and Internet of Things technology, the demand of individuals and enterprises for data storage, management and sharing is increasing day by day, which brings great development opportunities for the NAS market. According to the industry analysis report, the scale of NAS market is expected to expand at an alarming rate in the next few years and become one of the most potential growth points in the IT field.

Behind this trend is the higher requirements of society for flexibility, security and efficiency of data storage schemes. With the diversification of application scenarios such as telecommuting, home entertainment and smart home, users’ expectations for NAS products have gradually shifted from single data storage to more intelligent and humanized comprehensive services.

Faced with such a vast blue ocean market, manufacturers from all walks of life are gearing up to invest resources and strive to occupy a place in this emerging field. Based on this, Xiaomi turned his attention to the NAS industry. As a technology giant that started with smart phones and gradually expanded into smart homes, smart wear and other fields, Xiaomi has already occupied a pivotal position in the hearts of consumers with its strong brand influence and ecological chain layout. The demand survey of NAS products initiated by Chen Bo, general manager of Xiaomi Eco-chain, at Weibo undoubtedly released a strong signal — — Xiaomi is actively preparing to enter the NAS market.

The enthusiastic response of netizens, such as "Xiaomi NAS is coming?" "If you go out, you must buy it!" Comments, etc., clearly show the market’s expectations for Xiaomi NAS products. Xiaomi’s brand effect and user base, coupled with its rich experience in the field of smart home, make many people in the industry think that Xiaomi has the ability to build a highly competitive NAS product in a short time, and even some commentators bluntly said: "If Xiaomi NAS can imitate 90% according to the extreme space, it will be enough." This is not only the recognition of extreme space, but also reflects the potential advantages of Xiaomi in product design and marketing strategy.

Coincidentally, Xiaomi is not the only one who focuses on the NAS market. As a well-known provider of hardware detection and optimization tools in China, Master Lu also launched its NAS product: Master Lu AI NAS. However, Master Lu’s AI NAS is not a traditional NAS product, but more a network disk service with NAS function. Compared with the finished NAS represented by extreme space, the actual experience still has a certain gap.

The concept of AI NAS occupies the minds of users, and the sales volume of polar space continues to rise.

However, in the Red Sea competition of NAS industry, Polar Space has become the leader of the new forces of NAS with its unique AI NAS concept. In terms of product concept, we have a deep understanding that future NAS products should not only be data storage, but should become intelligent managers of data. By integrating artificial intelligence technology into NAS, products with extreme space can realize automatic classification, intelligent retrieval, data protection and other functions, which greatly improves users’ work efficiency and experience.

It is also based on this that during the recent "618 Promotion" period, Extreme Space NAS Private Cloud achieved the leading sales volume on both JD.COM and Tmall platforms with its superior product strength and user reputation. Its Z4Pro and Z2Pro products became TOP1 products sold by Tmall and JD.COM respectively, and the total omni-channel sales of other NAS products increased by more than 100% year-on-year.

Based on the successful experience of the home NAS industry, Polar Space began to accurately launch the enterprise-level NAS track, showing its long-term development vision and strategic planning. In the first half of this year, Polar Space launched a P8 tailored for the enterprise-level market. In the enterprise track, polar space not only pays attention to the high performance and stability of hardware, but also regards the deep integration of software and services as the key to the success of enterprise-level products, thus constructing a set of enterprise-level service system integrating software and hardware, and realizing the real whole chain optimization.

The polar space ZOS system leads innovation and creates a new storage experience.

The core of Extreme Space’s emergence lies in its well-designed ZOS system. The system deeply practiced the user-centered concept at the beginning of its design, which not only upgraded its functions in an all-round way, but also achieved a qualitative leap in user experience. It has an intuitive and user-friendly interface design, which reduces the learning cost for users and fully supports multi-terminal access. No matter whether it is a PC, a mobile phone or a tablet, it can enjoy a consistent and smooth functional experience and realize seamless data docking and sharing.

ZOS system also integrates diversified functions such as extreme photo album, extreme film and television, extreme comics and so on, which makes users’ digital content management lively and interesting. It is particularly worth mentioning that ZOS system deeply integrates AI technology, which can realize functions such as fuzzy picture search, picture search and picture text recognition, making the intelligent management and retrieval of photos more efficient and accurate than ever before.

In addition, polar space directly deploys the AI model to local devices, which fundamentally avoids the need to upload user privacy data to the cloud, thus building a solid privacy protection barrier at the source and completely eliminating the hidden danger of privacy leakage.

Thanks to the optimization of various network protocols and algorithms, whether it is wireless or wired connection, polar space can ensure the efficiency and stability of data transmission. For example, p8 launched for enterprises supports dual 10Gigabit network port transmission, and Z4pro, a star product, supports the transmission speed of up to 1250MB/s, allowing users to bid farewell to waiting and enjoy instant file access and sharing.

The speed of system update leads the NAS market and creates a new ecology of intelligent storage.

What makes Extreme Space stand out in the NAS market is its almost abnormal system update speed, which is one of the important reasons why it is deeply loved by users.

Different from other NAS vendors’ herding system updates, Extreme Space has invested a lot of resources in system development and testing. Whether for fine-tuning and optimization of existing functions or introduction and realization of brand-new functions, Extreme Space constantly strives for perfection and perfection through OTA online upgrade technology, ensuring that every update can bring substantial improvement and promotion, and create an intelligent storage ecosystem full of vitality and vitality for users.

Taking the virtual machine function as an example, the addition of this function not only greatly expands the application scenarios of NAS, but also provides unprecedented flexibility and convenience for users. Through the virtual machine, users can run multiple operating systems and application software on the same device at the same time, so as to maximize the utilization of resources and facilitate management.

It is worth noting that the rapid response of polar space in system update is not blindly pursuing speed and ignoring quality. On the contrary, every update has undergone rigorous testing and verification to ensure that it can meet the highest standards in terms of stability, security and compatibility. This relentless pursuit of quality has enabled polar space NAS to rapidly iterate and win wide trust and praise from users.

tag

Looking forward to the future, with the continuous growth of data volume and the increasing diversification of user needs, the NAS industry will usher in a huge growth space. At the same time, we also have reason to believe that as the industry leader, Extreme Space will continue to maintain its leading position in the NAS market, lead the development of the NAS industry, push the whole industry towards a more mature and professional direction, and bring more and better data storage and management solutions to users. In the blue ocean of NAS, polar space has taken the lead in setting sail for a broader blue ocean.

OK！ Next, let’s sum up. I wonder if you are excited about this car introduced today?

　　A few days ago, we learned from Auchan Auto that its brand-new MPV model, Keshang, will be officially launched on January 17, with a total of 8 new models, and the pre-sale price range is 998-142,800 yuan.

　　In terms of appearance, Coshang adopts the design language of Auchan automobile family, the new car is equipped with the brand-new "Cloud Eagle" LOGO of Auchan brand, and the L-shaped daytime running light and the front bumper with transverse opening are designed through, which gives people a calm and balanced visual effect as a whole.

　　At the same time, the back row is also equipped with privacy glass. In terms of body size, its length, width and height are 4840×1860×1890mm and its wheelbase is 2820mm, which is superior to that of the same class.

　　In the interior part, the center console adopts the traditional layout form, which performs well in workmanship and materials, creating a certain sense of grade. The smoothness and display effect of the 10-inch central control large screen are good. In terms of appearance configuration, the biggest highlight of the new car is the double-sided electric sliding door. At the same time, the car is also equipped with LED daytime running lights, LED front fog lights and LED taillights, and the LOGO floor lamp is also added. The headlights also have the effect of breathing and lighting. At the same time, it is equipped with a 1.14㎡ electric panoramic sunroof to enhance the ride experience.

　　In terms of power, it provides two systems of 1.5T and 1.5T+ hybrid motor, in which the maximum power of 1.5T engine is 156 HP and the peak torque is 225 Nm, and the transmission system is matched with 6MT and 7DCT.

　　　　There are many stars who are not of their own nationality. For example, Hu Bing is Thai, Summer Xu is Japanese and Jet Li is American. I dare not say about other stars, because I don’t understand them. But I know a little about why Jet Li gave up his China citizenship and got American citizenship, and many of his friends gave up China citizenship and joined other countries for the same reason. Even in the rain, I almost took the same road, but I didn’t give up because of "bad luck"

　　　　It is not clear where Jet Li was born. He grew up in Beijing. Since childhood, he has entered Beijing Sports School to study martial arts, and his achievements are obvious to all. But Jet Li can’t be regarded as a real Beijinger, because he doesn’t have a Beijing hukou and his parents are not Beijingers. Although he won the national Wushu championship and became a martial arts star because of Shaolin Temple, he was helpless in the face of China’s strict household registration system. Because he doesn’t have a Beijing hukou, his unit in Beijing is just a temporary worker, and he can’t enjoy the treatment that an ordinary person should have, let alone the treatment of a star and his career.

　　　　He is weak in the face of registered permanent residence and China’s personnel treatment. He can’t shake this strict household registration and personnel system at all. He can only enjoy the treatment of second-class citizens in Beijing. Brave and invincible on the screen, he can only choose to escape.

　　　　At this time, Hollywood waved to him. In Hollywood, he found his stage. With his talent, he quickly acquired American citizenship and obtained an American hukou.

　　　　This story of Jet Li has been staged more than ten thousand times in our motherland. Therefore, when we question their behaviors, why don’t we deeply investigate the reasons behind them?

With the increasing trend of electrification, unlike traditional fuel vehicles, the power structure of new energy vehicles is more complex and changeable, almost a brand and a structure, such as Geely Hi·P, BYD DM-i and so on. A hundred flowers blossom, which may be to describe the current hybrid car market. Therefore, as a fan of Lectra 03, I naturally became interested in the current hybrid technology of Lectra brand. I believe that friends who don’t know much about hybrid but prefer Lectra brand also have many questions. For example, what does the P1+P3+P4 motor scheme adopted by Lectra EM-P high-end models mean now? Is it good or not? Don’t worry, an article will give you the answer.

Looking at all the models currently on sale at Lectra, except for Lectra 01 and Lectra 03 and EM-F hybrid models with blue brand, all other hybrid models adopt EM-P plug-in hybrid drive with green brand.

What is "Px Hybrid"?

And if you want to understand the LECK EM-P, you must first understand the "Px hybrid". In fact, the term "Px hybrid" refers to the position of the motor. At the same time, different positions will also affect the connection between the motor and the gearbox, and will also change the parallel or series-parallel connection between the gearbox and the motor. P here means position. For the single-motor hybrid power system, according to the position of the motor relative to the traditional power system, the single-motor hybrid schemes can be divided into five categories, named P0, P1, P2, P3 and P4 respectively.

So knowing the concept of "Px hybrid", is it good to lead the hybrid architecture of EM-P? We will analyze them one by one.

The first is P1, whose motor position is in front of the gearbox and installed on the crankshaft of the engine, that is, the original flywheel position. The engine crankshaft acts as the rotor of ISG motor, so it also supports engine start-stop and braking energy recovery to generate electricity. Therefore, the transmission efficiency of P1 layout with mechanical connection will be much higher.

But it is P3 and P4 that really start to feel "pure electricity". The former is integrated in the back end of DHT-that is to say, P3 is essentially an EV direct driver. P4 is only related to the rear axle, which is a common "rear motor" for pure electric vehicles. It will be directly mounted on the rear axle of the vehicle and directly act on driving the rear wheels. Its main purpose is to realize four-wheel drive and energy recovery. Moreover, the motor and the engine are actually coupled through the ground, and although its working properties are similar to other simple parallel connections, there is no mechanical connection inside the vehicle.

What is the layout of lectra EM-P?

After reading the principles, advantages and disadvantages of three different motor positions, let’s talk back to Lectra. In fact, the layout of P1+P3+P4 adopted by LEEK EM-P is only adopted by LEEK 08 and LEEK 09, while LEEK 01PHEV just released some time ago adopts LEEK’s unique "P2.5 architecture", and its officially claimed "P2.5 architecture" should be similar to P3, but technically speaking, it should be an upgraded version of P2. Its motor is not directly connected with the input shaft of the dual-clutch gearbox, but connected with the input shaft in charge of gears 2, 4, 6 and R, which can be regarded as improving the impact of oil-electricity connection and avoiding many technical problems of P2 and P3 with higher integration.

Let’s take a look at the advantages of the third DHT gear of the tram. In fact, the gear setting of the third gear DHT of the tram is similar to that of the oil truck. When the vehicle is driving in the high-speed range, the torque of the single gear is insufficient, and the three-gear DHT model can improve the torque of the vehicle by adjusting the gear, so that it can still drive in the high-speed range calmly. Then why do so many car companies still insist on using single-gear DHT? This is because the hybrid structure itself is more complicated, and it is difficult to realize the hybrid structure of some car companies by adding the transmission system in a limited space.

Is lectra EM-P the leading hybrid architecture?

Having said so much about the technical application of Lexus, you may not have much idea. Let’s talk about what EM-P models can bring us in daily driving. Let’s take the 2023 LECK 08EM-P four-wheel drive performance Halo version as an example. It adopts the layout of P1+P3+P4. In the most common urban commuting road conditions, such a car scene can be driven in pure electric mode. The battery life of CLTC 220km is enough for most people to charge in 3-4 days. In pure electric mode, only the motor drives the vehicle, which has exactly the same driving experience as a pure tram.

When our vehicle speed is above 88km/h, the engine will be involved in driving. It can be said that this set of EM-P hybrid, while driving close to the pure tram in daily life, also has the endurance far beyond the pure tram. When the vehicle needs to start quickly from a static state, the ejection start mode of this system can also be completed by making the engine and P1, P3 and P4 motors work together and accelerating at 0-100km/h for 4.6 seconds. When the vehicle drives to the elevated or loop, the system will judge whether the engine is involved according to the driver’s power request. When the driver needs to overtake, DHT Evo transmission can downshift, increase the torque of the engine and help the vehicle overtake quickly. On the highway cruising at 120km/h, EM-P will give priority to engine direct drive. Compared with the insertion and mixing of single gear, DHT Evo is more calm and has gears available. At present, Lectra EM-P is a leading hybrid structure in the industry.

Therefore, we can sum up the advantages of Lectra EM-P in one sentence: it lasts longer than pure trams, is stronger than ordinary hybrid cars, and is more energy-saving than extended-range cars. Finally, answer another question-how does Lectra EM-P compare with BYD DM-i? If we want to compare the two, because EM-P uses a 3-speed DHT hybrid special gearbox, and the hybrid structure is more complicated, while DM-i can only drive directly in a single gear, so it is more advantageous to overtake EM-P in a high-speed range. After all, 3-speed DHT is adopted. Disadvantages: Theoretically, the failure rate of EM-P may be higher than that of DM-i with simple structure, but this is only in theory. After all, there is no report on the failure of Lectra EM-P power system, which shows that its stability is also very good.
