　　　　On January 31, 2008, the electromagnetic gun was launched by the US Navy’s surface warfare center, and the wavy lines formed by the violent impact of the warhead on the air were faintly visible. The photo was taken by a high-speed camera. U.s. navy pictures

　　　　Global Times Global Network News: 20,000 km/h high-speed artillery shells used to be science fiction dreams, but now this has become possible. On January 31st, 2008, the US Navy’s Surface Warfare Center (NSWC) in Dahlgren, Virginia successfully launched an rail gun. This advanced cannon can hit Moscow!

　　　　According to the Russian Morning Post on February 1st, the Pentagon News Center announced that the United States had successfully launched a new type of rail gun. On January 31st, experts from the Weapon Development Center of the Naval Surface Warfare Center of the United States tested the performance of the Super rail gun.

　　　　The characteristic of this type of weapon is that the projectile used for acceleration is not traditional gunpowder, but electromagnetic energy. This will get an unprecedented index: it takes only 0.2 seconds to accelerate the ammunition launch from 0 to 21,000 km/h!

　　　　The United States conducted this kind of experiment as early as 1980, and produced the first sample in 2005. The next generation of warships will be equipped with rail gun.

　　　　The advantage of this railgun is that because ordinary gunpowder is not used, there is no need for a special ammunition depot on the warship, which can greatly save space, but designers must consider the device that generates huge electricity.

　　　　The shell has a range of 370 to 400 kilometers, and it is also equipped with a satellite positioning system, which can accurately lock the target to the maximum extent with an error of no more than 5 meters. The shortest distance between Moscow and Russia is 400 kilometers. Theoretically speaking, the US Naval Surface Warfare Center has posed a real threat to Russia.

　　　　The shells mainly fly within the atmosphere (about 200 kilometers), with a total flight time of 6 minutes.

　　　　It should be pointed out that there is no detonator in rail gun: designers hit the target by hitting the dynamic energy. (Global Network Liang Xu)

★ Coating of Mercedes NANOSLIDE Cylinder and Honing Process of CONICSHAPE Cylinder

　　It is reported that compared with the traditional cylinder liner, the patented technology of Mercedes-Benz can reduce the friction loss of the cylinder by about 50%, the heat can be conducted to the cooling system more quickly, the compression ratio can be set higher, and the engine oil with lower viscosity can be used.

　　At the same time, the small holes on the surface can’t store the engine oil normally. After the engine oil is brought into the combustion chamber by the piston, the carbon deposition will become more and more serious, and the price of future maintenance is much higher than that of engines using cylinder liners.

★ CAMTRONIC variable valve lift and piezoelectric injector

　　Among them, the intake valve can be opened in the crank angle range of 4 before TDC to 36 after TDC, and the exhaust valve can be closed in the crank angle range of 25 before TDC to 15 after TDC. This adjustment method can make the valve overlap angle change in a wider range, thus obtaining more economical ignition timing.

　　On the one hand, the adjustable valve lift can ensure the best combustion effect by combining multiple fuel injections with multiple ignition of spark plugs (generally 5 times), and can also make up for the reduced turbulence of combustible mixed gas in the combustion chamber.

　　However, multiple ignition will greatly shorten the life of spark plugs, that is to say, in the current generation (|), the life of spark plugs is about one-fifth of that of ordinary single-ignition engines.

★ New turbine technology

　　In the brand-new engine, the 2.0T version will add an electric turbocharger on the basis of the exhaust gas turbine, that is, the configuration of double turbines. It is reported that the C300 model will be equipped with this engine.

　　The electric turbine is equipped with a brushless DC motor, which has the ability to increase the speed to 7000 rpm in 0.3 seconds. The turbo lag phenomenon can almost be avoided, but according to foreign media, the energy consumption of this electric turbocharger is still relatively large.

　　The electric exhaust gas turbine is connected with the engine cooling circuit, and the maximum speed can reach 170,000 rpm, which can achieve a very high airflow speed and keep the boost pressure for a period of time. Even if the driver has started braking, he can respond quickly when power is needed.

★ Full text summary

　　The fully optimized M254 1.5T+48V light-mixed engine, with the blessing of the above advanced technologies, is a completely new change compared with the previous generation models, and finally returns to the same starting line as BMW and Audi’s 2.0T, and the strategies of electrification and energy saving and emission reduction are equally significant to enterprises. However, from the consumer’s point of view, the nightmare of M264 is not far away, and the brand-new M254 is bound to make consumers pay more attention to it, just as the brand-new C-class has exposed problems such as central control screen, driver assistance system failure and passive safety system failure, which inevitably makes people sigh that things are good things, but it still has a long way to go to make consumers accept them.

　　[Professional Test] It is not enough to look at the comprehensive endurance of a pure electric vehicle. First of all, the comprehensive cruising range is tested in an ideal test environment, and the road environment in real life is much more complicated than the test environment; Secondly, if you only drive on the highway at a relatively high speed, the actual cruising range will definitely be less than the comprehensive cruising range, because high-speed driving is a working state with high energy consumption for pure electric vehicles. However, as a car, it is also one of its "jobs" to run long distances and take high speed. So how does a pure electric vehicle with a comprehensive cruising range of more than 450km perform at high speed? Today, we found such a car and tested it for everyone.

　　The 2018 500 is a new model launched by Tengshi in March this year. Like the old models, it is positioned as a medium-sized pure electric vehicle. The biggest highlight of the car is its comprehensive cruising range of 451km, which is due to its lithium iron phosphate battery with a capacity of 70kWh. The car has two models, the fashion version and the glory version, and the latter is the top model of the car. Today, the test car we got is Tengshi 500 Glory Edition. Apart from the difference in configuration, the powertrain is also different. From the data point of view, the power performance of Glory Edition is better.

After reading the following, you have read 70% of the full text:

　　1. The comprehensive cruising range of the Ministry of Industry and Information Technology of the new car has increased to 451km, which is 99km； more than the old model;

　　2. It can travel 290km under high-speed working conditions, and the charge after high-speed driving can reach 57kW, and 80% of the power can be recovered in about one hour;

　　3. Driving for 200km in urban areas, with a remaining cruising range of 240km；;

　　4. The dynamic response is good, and the acceleration of 0-100km/h is 9.65 seconds.

　　If you want to know how these results are tested, and what kind of reference value these results have in your travel and driving process, please see our test content later.

● Endurance test

　　In order to carry out the endurance test closer to the real car scene and give friends who are concerned about pure electric vehicles more meaningful endurance test results, we will conduct the test according to the following conditions in the future:

　　1. During the high-speed endurance test, the average speed is 90km/h 2 km/h, and this speed setting will basically be achieved by using the speed of 100-120km/h most of the time in the actual driving process. This operation is to restore the actual car scene on the expressway as much as possible, and it will not lead to dangerous high-speed driving behaviors such as slow driving and speeding.

　　2. During the low-speed endurance test, the average speed is 30 km/h 2 km/h, which can simulate the actual situation of the vehicle as much as possible, including waiting for traffic lights, traffic jams, high-speed loop driving, etc.

　　3. During the test, if the air conditioner is turned on, we will record the turned-on state (cold and warm air) and the turned-on time in detail. After all, on pure electric vehicles, the air conditioning components are considered as high-power electrical appliances on the car, and we will explain to our friends how the air conditioner affects the cruising range.

　　First of all, before introducing the test process in detail, we will show the results of the endurance test to our friends. Because the power display of Tengshi 500 is not an accurate value, the following power values are all estimated values:

◆ High-speed battery life: "far" running and fast charging.

　　Tengshi has used the recent average energy consumption to calculate the remaining cruising range since the first model. This algorithm will calculate according to the recent energy consumption state and remaining power, and show how many kilometers the vehicle can travel under the current energy consumption state. It is somewhat similar to the computational logic we have tested before.

　　If the energy consumption state of a vehicle changes constantly through a variety of complex road conditions during a trip, the remaining cruising range value will also change frequently: the high-energy time-consuming value will decrease sharply, and the low-energy time-consuming value may increase. At first, it may make drivers feel confused and don’t know when to refer to the value, but this algorithm actually reflects the remaining endurance of the vehicle at a certain energy consumption level and can remind drivers of the influence of driving style on the endurance of the vehicle.

　　Judging from the models we have tested at present, we can travel 290km at an average speed of 90km/h, which is quite good among pure electric vehicles. Without charging in the middle, you can run to Shijiazhuang with full charge (Baidu map query is from Zhongguancun in Beijing to Huaibei Park in Shijiazhuang, the whole journey is 289.7km, and it is basically no problem to drive at high speed). However, due to the weight of the car and the wind resistance of the car body, the power consumption per 100 kilometers at high speed reaches 20.9kWh/100km, and the energy consumption level is still relatively high. However, Tengshi 500 power battery itself has a capacity of 70kWh, so 15% of the power can still support the car to travel 52km in this energy consumption state. If you drive on the main highway, the remaining cruising range can basically reach the next charging station in the service area.

　　Although Tengshi 500′ s high-speed endurance performance is good, here we still suggest that friends plan the interval of charging stations at 280-290km for high-speed travel to avoid the situation of power failure. In winter, it is necessary to reduce the mileage interval of route planning. After all, air conditioning and warm air consume more electricity than air conditioning and refrigeration.

◆ Charging performance: the battery will charge quickly when it is hot.

　　From the charging information, we can see that when the temperature of the power battery reaches 41℃, the charging current and voltage are relatively high. According to the charging power displayed on the charging pile, the charging power is about 57kW. If charging in this state, the power of the power battery can be charged in one hour. According to the conversion of 70kWh into percentage, the charged power is about 81%. It can be seen that it is possible to charge the power battery to 80% within one hour when the temperature of the power battery is high.

◆ Low speed battery life:

　　Driving at an average speed of 29.5km/h for 200km consumes about 51% of electricity, leaving a battery life of 240km. Although this achievement does not exceed the cruising range of the Ministry of Industry and Information Technology for 451km at present, according to the measured cruising capacity, it is completely possible to charge once a week if the commuting distance is 40km per day. Not only that, even if the power is not enough, it will remain at about 50%, and the travel needs of other urban areas outside the daily commute or to and from the airport can still be met.

Wow, fellow riders! Today, Xiaobian is going to give you a big story! You know what? At the just-concluded 2024 Tianjin Auto Show, the shoulder of our domestic luxury brand brought a heavy new car, which is the legendary "Guoya"! This is no ordinary new car, but a super luxury car that wants to wrestle with Mercedes!

Having said that, I can’t help but think of a paragraph I brushed in my circle of friends a few days ago:

"Lao Wang: I just bought a new car, which is more expensive than that!
Lao Li: Wow, did you buy Maibakh?
Lao Wang: No, I bought it! "

Yes, that’s it! Our domestic luxury car is finally going to make a big splash in the high-end market!

But wait, is it really that good?

Let’s take a look at the ins and outs of this "elegant instrument of the country"!

Remember watching the military parade when I was a child, the majestic red-flag car? That’s a special car for state guests! But now, as long as you pay 20 thousand yuan, you can book a red flag Guoya! What kind of fairy operation is this?

Actually, it all starts with the transformation of Hongqi brand. The former red flag, like a cold goddess, can only be seen from a distance and cannot be used for fun. But now? It has transformed itself into a big sister next door, kind but noble. Isn’t this change the epitome of the development of China’s automobile industry?

Speaking of Guoya’s motivation, that would be great. 4.0T hybrid system with maximum power of 360kW and maximum speed of 250km/h.. As soon as this data came out, my first reaction was: Is this allowed to take off?

Imagine that you are cruising Guoya on the highway, and your friends next to you are still worried about saving fuel. What about you? There is not only the surging power brought by large displacement, but also the energy-saving blessing of hybrid system. This is simply the rhythm that both fish and bear’s paw want!

Yan value is justice, which is more appropriate for Guoya. The body length of 5.3 meters, the large-size vertical banner with domineering side leakage and the chrome-plated front grille, as well as the red flag that can be lifted and lit, are simply moving works of art!

The interior is even more magnificent. Violet with ultra-white, terracotta brown with graphite black, spring wild green with rain ash ….. How does this color scheme sound like reading a poem? It’s probably more comfortable to sit in than a five-star hotel!

To tell the truth, when I saw Guoya going to compete with Mercedes-Benz Maibakh S-Class, my first reaction was: Are you kidding? But on second thought, why not?

Isn’t our high-speed rail in China already ahead of the world? Which field of mobile phones and home appliances is not killing foreign brands crying? Why can’t the automobile industry work? Besides, Huawei can build a car. What’s wrong with an old brand like Hongqi building a luxury car?

Some people say that the emergence of Guoya will stir up a pool of spring water in the luxury car market. But I think the water in this pool has already been turned upside down, okay?

Not to mention showstopper like Tesla, even sports car brands like Porsche and Ferrari are building SUVs. In this era when everyone wants to be online celebrity, how can there be a peaceful life in the luxury car market?

But then again, the emergence of Guoya may really bring some new possibilities to this market. After all, the label Made in China has changed from cheap to synonymous with high quality. Why not luxury cars?

Finally, I want to say that no matter whether Guoya can succeed in the end, its appearance is something to celebrate. Because it represents an important breakthrough in China’s automobile industry and represents that we are moving from a big automobile country to a powerful automobile country.

Then the question is coming. If you had a choice, would you buy Guoya or an imported luxury car? Welcome to leave a message in the comment area, let’s discuss this topic together!
