Since its inception, with its unique identity, it has undertaken the heavy task of brand electrification transformation. As a fusion of classic and innovative, it not only continues the classic elements of the brand, but also deeply integrates the pure electric platform for positive research and development, becoming the representative of pure electric in the new era.

In 2023, Porsche sold more than 320,000 new cars worldwide, of which the Taycan sold more than 40,000 units, which is enough to prove the important position of the Taycan in the Porsche series and its recognition in the hearts of consumers.

Recently, the new Porsche Taycan with a new upgrade and configuration again, released a total of 7 models, including sports cars and Cross Turismo two body forms, all standard high-performance batteries. The starting price of the new Taycan is more than one million yuan, and the price of the whole series is 100.8-199 8,000 yuan.

The new Taycan has been adjusted in detail in the front face, and the optimization of the air inlet shape has improved the effect, up to a minimum of 0.22. The new style of lamp group design is matched with high definition matrix (HD) technology, and the interior of the headlight is composed of 32,000 LED light sources, which further enhances the lighting effect and safety.

Externally, the new Taycan’s front fenders and flatter headlights visually widen the car’s width, and the Porsche logo in the strip taillights features a three-dimensional glass exterior design and supports lighting, adding a unique welcome/departure animation effect.

In terms of performance, the new Taycan is equipped with new 21-inch tires with lower rolling resistance, which helps to improve battery life. The battery capacity has been increased from 93kWh to 105kWh, and the WLTP range has been increased to a maximum of 693km. At the 800V DC charging station, the maximum charging power of the new car can reach 320kW, which is 145kW higher than before, and the fast charging time is greatly shortened.

In terms of configuration, the new Taycan has been fully upgraded, including sound system, front seat heating, wireless charging + smartphone tray, etc., to improve convenience and comfort. In addition, the configuration of electric charging port cover, adaptive air suspension, rearview mirror rim light has also been upgraded.

In terms of power performance, the new Taycan also spares no effort. Take the Taycan Turbo S as an example, the system can reach a maximum power of 700kW, and the 0-100km/h acceleration time is only 2.4 seconds. The Push-to-Pass (one-click acceleration) function in the Sport Chrono component can output up to 70kW of additional power in 10 seconds.

On the track, the new Taycan also showed its outstanding performance. Equipped with Weissach components, the Taycan Turbo GT with Weissach Package achieved the fastest lap time of 1:27.87 at Laguna Seca Circuit in the United States, becoming the fastest pure electric production car on the track.

Since its launch in 2019, the Porsche Taycan has become a model of performance in the electric sports car industry with its outstanding performance and continuous innovation. The comprehensive upgrade of the new Taycan in terms of performance, battery life and configuration will undoubtedly further consolidate its leading position in the ultra-luxury brand electric sports car. For Taycan owners, "this is still a Porsche" is not only a recognition of its performance, but also a legacy of its brand spirit.

The domestic automobile market is no longer new for cross-border car-making. In the early years, most of the new power brands started in the Internet industry. In recent years, all walks of life hope to get a share in the automobile market. Not only do people who make mobile phones and color TVs keep pouring into the car circle, but even those who make sweeping robots and engage in real estate development are building cars.

Then, will the brand that makes air conditioners be absent? Of course not. Gree is the representative. Recently, Shanghai Gree Automobile Technology Co., Ltd. was established with a registered capital of 20 million RMB, and its business scope includes automobile parts research and development, automobile parts and accessories manufacturing, industrial robot manufacturing, industrial robot sales, intelligent robot research and development, etc. Obviously, Gree is already paving the way for building a car.

Has Dong Mingzhu learned a lesson from Gree’s second-hand car?

On the surface, Shanghai Gree Automobile Technology Co., Ltd. was established only recently, but in fact this is not the first time Gree has built a car. As early as 2016, Gree Electric was prepared to acquire 100% shares of Zhuhai Yinlong for 13 billion yuan. Although the acquisition was stalled due to the opposition of Gree shareholders, it also opened the prelude to Dong Mingzhu’s intention to build a car.

In desperation, Dong Mingzhu invested 1 billion yuan in his own name to acquire the shares of Zhuhai Yinlong, and after repeated capital increase, Dong Mingzhu’s shareholding ratio increased to 17.46%, which made Dong Mingzhu realize his dream of building a car. But after all, investment acquisition is only the beginning of the dream of building a car. If you want to survive in the automobile market, you must come up with satisfactory products.

From the product point of view, Guangtong, the first model after Dong Mingzhu’s shareholding in Zhuhai Yinlong, has been listed in 2017, and the voice of doubt is not small, not only the longest battery life is only 200km, but even the top speed is only 120km/h, so it is naturally difficult to measure the product strength without bright spots. Although the second model, Yinlong Effie, has increased its battery life to 450km, the price of over 400,000 yuan has also been directly taught by the market.

In the days to come, Yinlong Automobile was also in constant trouble. Even in 2018, it was exposed to negative news such as arrears in supplier payment and arrears in employee wages. In 2019, Gree intended to cooperate with Weimar to change the status quo of Yinlong Automobile, but soon Weimar went bankrupt and there was no following. In the end, Yinlong Automobile was renamed as "Gree Titanium" in 2021. In 2023, Gree Electric increased its shareholding in Gree Titanium to 72.47%, which was managed by Dong Mingzhu himself.

All of the above shows that Dong Mingzhu doesn’t know much about the automobile market, and building a car is far from as simple as Dong Mingzhu imagined. With the establishment of Shanghai Gree Automobile Technology Co., Ltd., the second car-making in Dong Mingzhu started. Behind this is not only Dong Mingzhu’s obsession with the dream of making cars, but also the huge profits in the automobile market, otherwise there would not be so many people trying to squeeze into the automobile market. However, has Dong Mingzhu learned the lesson of Yinlong’s failure?

It is not easy to build a car, and Dong Mingzhu’s dream of building a car will fail again

There is no denying that Gree is a leading enterprise in the air-conditioning industry, and its sales volume and influence are hard to match with those of its friends. Dong Mingzhu, who pushed Gree to the top with one hand, is naturally proud of making cars. He once bombarded domestic cars in public, but when he built them himself, he found that making cars was far from as simple as he thought.

Why did Yinlong fail? In fact, the technology is still too bad, and at the same time, Dong Mingzhu himself is arrogant, pulling the pricing of Yinlong’s products to a height that does not belong to it. What’s more, the models of Yinlong Automobile are "knockoffs" from any angle, but they are higher than the genuine ones in price. Is it because the Logo of Yinlong Automobile uses five rings more than the four rings of Audi?

If Dong Mingzhu paid attention to product building and technology research and development when it first built a car in 2016, perhaps the dream of building a car had already come true. But now it’s 2024. Can dreams that were not realized eight years ago be realized now? Compared with eight years ago, the involution of the current automobile market is completely out of one dimension. Except Xiaomi, the new power brands established in the past two years have failed to make waves without exception.

For the new power brands, there are actually only two ways to go, either relying on traditional automobile manufacturers, such as Deep Blue Automobile, Extreme Krypton Automobile and Intimate Automobile, and relying on traditional manufacturers such as Chang ‘an, Geely and SAIC respectively. There is neither a lack of technology nor a lack of R&D funds, and at the same time, brand awareness can be established. The other way is to become popular by marketing, just like Xiaomi Automobile, but the premise behind marketing is that the competitiveness of the product itself is not bad, and the quality cannot be too flawed. The most important thing is that the founder must be as influential as Lei Jun.

It’s a pity that there seems to be some gap between Dong Mingzhu and Lei Jun now, and Dong Mingzhu is not satisfactory in both personality charm and rigor in making cars. In addition, although Dong Mingzhu and Gree have 8 years of experience in building cars, they can hardly come up with the core technology. The only advantage may be car air conditioning. After all, this is Gree’s housekeeping skill.

Write at the end:

In the field of air-conditioning, Dong Mingzhu is undoubtedly successful, but the profit and development potential of the air-conditioning market are limited after all, so Dong Mingzhu hopes to enter more industries. However, judging from the results, almost all cross-border ventures in Dong Mingzhu have ended in failure, and both the former Gree mobile phone and the current Gree Titanium car have become jokes in the circle. So, do you think Dong Mingzhu’s dream of building a second car can come true?

As we all know, the valve cover is usually located at the top of the engine, and the oil filler, ignition coil and other components are installed with it. With the increasing integration of the engine, the responsibilities of the valve cover are increasing.

Therefore, if the valve cover fails, it will seriously affect the running state of the engine.

01

Fault case: air conditioning odor caused by aging of valve cover

A limousine entered the repair shop, and the owner complained that the air from the air conditioner smelled burnt. Maintenance personnel try air conditioning, and they can smell obvious odor during external circulation, but there is almost no odor during internal circulation. Open the engine compartment and look carefully. It is found that the oil drips on the high-temperature engine parts, releasing the burnt smell, and then being sucked into the car from the air inlet of the air conditioner.

Air conditioning outlet smells bad.

Following the trace of oil leakage, the source of oil leakage was found, which was that the valve cover was aging and cracked, resulting in oil leakage. Replace the valve cover assembly, clean up the leaked oil, and after replacing the air conditioner filter, the air conditioner odor disappears and the fault is eliminated.

Aging valve cover

The source of the above faults is the aging of valve cover and oil leakage. However, the consequence of aging of this part is not only the phenomenon of air conditioning odor.

02

The valve cover is abnormal, and there are various problems.

The engine is developing in the direction of light weight and miniaturization, and many independent components in the past have begun to merge with each other and integrate into one. For this reason, in the valve cover of today’s mainstream models, seals, valves, oil mist separators, etc. are generally integrated to form an assembly.

Obviously, when the valve cover fails, its impact will be various. The following are some common phenomena:

Seal failure: Oil leaks out of the engine, resulting in oil consumption.

Increase of sludge: oil leaks into the cylinder head, camshaft and valve contact with too much oil, and sludge increases, which affects the action.

Carbon deposit in the cylinder: the oil enters the spark plug hole, which affects the spark plug flashover and forms carbon deposit in the cylinder.

Harness damage: oozing oil will flow along the harness and cause poor contact of the connector.

03

Possible causes of valve cover damage

Natural aging is one of the reasons, and the failure of some other systems on the engine will also lead to the damage or performance degradation of the valve cover.

The first is the temperature. There are many engineering plastics and rubber products in the valve cover. If the engine runs at high temperature for a long time, these parts will age rapidly.

Seal on valve cover

The second is stress. If the crankcase is not well ventilated, the internal pressure of the engine will increase, which will bring additional load to the seal and make it more prone to fatigue.

In addition, human factors can not be ignored. When installing the valve cover, the bolts must be tightened in strict accordance with the order indicated by the technical data of the main engine factory, otherwise the sealing may be lax and repair may be brought.
