Family carThere are generally three types of gearboxes, AT, CVT and dual clutch. American GM and Ford generally use AT, Japanese mostly use CVT (AT), German mostly use dry dual clutch (self-priming is matching Aisin 6AT), Korean mostly use AT and dual clutch, and domestic majority. What kind of gearbox is good? Each has its advantages and disadvantages! Let’s share our choices about:

AT gearbox

1. love letter AT. The external sales of this gearbox should be the most. The quality and stability market can show that some domestic models are also equipped with Aisin 6AT and 8AT. This brand AT has smooth gear shifting, good fuel economy and can adapt well to different road conditions. Among them, 6AT is divided into high and low power versions, which seems to be the low power version, but it is completely sufficient for the self-priming engine, and it is equipped with the high power version.

2. ZF 8AT. This gearbox has strong performance and high efficiency, and is basically used in German luxury brands, such as BMW 3, 5 and 7 series, and some models are also equipped.

3. Universal 9AT. This gearbox has a moderate upper and lower speed, but the throttle response is fast after the speed goes up. Secondly, Ford 8AT was developed in cooperation with GM, and one group was reduced on the basis of 9AT.

4. Modern 6AT and 8AT. Modern AT has strong stability and good ride comfort. Because the modern gearbox and engine are not only developed by themselves, but also the control programs of the engine and gearbox are developed by themselves, they feel good ride comfort when driving, and generally carry their own models.

5. Fuzhen 8AT. The first self-developed AT gearbox in China, many AT gearboxes are basically in the hands of international first-line car companies. Under such circumstances, it is very difficult to develop AT, which is worthy of admiration. Just like, this is not something that can be done overnight, but a long-term persistence. The new engine 2.0T is equipped with this gearbox.

6. AT gearbox structure. Mainly planetary gears, generally there are several groups of planetary gears with several gears. The power output by the engine is transmitted by the oil in the hydraulic torque converter in the gearbox, and it will lock up when the speed reaches a certain level. Compared with dual clutch, AT has smaller volume and more mature technology.

continuously variable transmission

CVT gearbox, two combinations, chain or steel belt is in the middle of two vertebrae, and the chain type can bear more than the steel belt type. The advantages of CVT are better ride comfort in power transmission than dual clutch, low cost and fuel economy. Disadvantages can not bear large torque, family cars are generally CVT, luxury cars rarely use CVT. Pro uses steel chain CVT, which is not easy to slip compared with steel belt type.

Dual clutch and manual gearbox are somewhat similar. Double clutch can be divided into wet clutch and dry clutch. The main difference between dry clutch and wet clutch is that the oil is added around the clutch plate, so the heat dissipation is relatively better. Theoretically, wet clutch is better than dry clutch. The advantages of dual clutch are fast shifting and high power transmission efficiency. The disadvantage is thAT the smoothness of at and CVT gearboxes is slightly worse. Most models under 150,000 are dual-clutch, but due to the fast shift, most of them use dual-clutch gearbox, but the quality is definitely higher.

summary

There are no perfect products, only products that suit you! Among the three, AT is more comprehensive, combining the advantages of CVT and dual clutch, but it is expensive, while CVT and dual clutch have their own advantages and disadvantages.

In recent years, my life has gradually entered the right track, and several major events in my life have been successfully completed. Falling in love, getting married, buying a house and having children, everything makes me feel very happy, and of course buying a car is the same. When I first got married, I didn’t feel how important a private car was, but when my daughter-in-law became pregnant, she often had to go to the hospital for examination. At this time, it was inconvenient to take the bus, especially in case of an emergency at night, it was more convenient to have a private car, so buying a car was gradually put on the agenda.

After we got married, we also saved some money with our daughter-in-law, and with the support of our parents, we can still afford to buy a 100,000-class family sedan. Moreover, my daughter-in-law and I have the same opinion. How much money we have to buy a car at what price? There is no need to pay a down payment to save face and buy a relatively expensive model. Carrying a heavy loan on your back puts you under a lot of pressure, which is not worth the loss.

It happened that we had a local auto show in May. After doing our homework online, we went to see the car with our daughter-in-law. The models we are mainly concerned about are Nissan, Volkswagen, Volkswagen, Changan PLUS and New China. It took us nearly one morning to read all the models, and the feeling is still very deep after the comparison. Nowadays, there is no doubt that the workmanship of domestic cars and Yan value joint venture brands can’t be compared at all. Then, the price of domestic cars is more advantageous. At the same price, you can choose the top match for domestic cars, but the joint venture car can only buy automatic low gear or manual gear.

At this time, my heart has been more inclined to domestic cars, especially my daughter-in-law, because she is a face value control. After that, I asked a few friends who drive domestic cars, and they all said that there is nothing wrong with the three major parts of domestic cars now, and it is meaningless to buy a 1.5L joint venture car with a budget of 100,000 yuan. Buying Changan PLUS, a domestic car, can choose the 1.4T version, and the power performance is quite good. In particular, a friend who runs Changan CS75 PLUS strongly recommended Changan brand to me, saying that it is absolutely worth the money.

After that, I was a little hesitant to buy a new one or Changan PLUS, just in time to catch up with the 2022 PLUS update. The new car added penetrating taillights, transparent chassis, automatic parking and other functions, and also replaced it with an electronic gear handle, and the cup holder area next to it was designed to look better. PLUS, there is only 1.5L version, so I finally decided to start with Plus.

Let’s share the car purchase price. I bought the 1.4T Premium Edition, with a final cash discount of 7,000 yuan. All the expenses add up to a landing price of 94,000 yuan. The 4S shop gave me a scratch insurance for one year and four basic maintenance for two years. This is the lowest price I can get. I don’t know if it is expensive.

Buying a new car is as enjoyable as marrying a bride. However, I was questioned by a neighbor. From his words, I obviously felt the meaning of looking down on domestic cars. When he saw me bring my new car home, he asked me how much it cost, and I told him truthfully. He said that he spent more than 90,000 yuan, so why not add a little money to buy one? Now the new model is a little more expensive, but you can buy the classic model, but it’s not worthwhile to buy it with a loan. At that time, I really saw the 1.5L automatic transmission with low gear, which gave me the feeling that it was shabby from the inside out. The bare car price of about 100 thousand had no function, and the interior was similar to that of a taxi, so I really couldn’t get it. I don’t know how to get a sense of superiority when buying it.

What this neighbor bought was a 1.4T model. At that time, the landing price seemed to be more than 140,000, which was still bought by loan. Now he has to pay more than 2,000 yuan a month, and the economic situation is currently sluggish. Now it is rare for him to drive when he goes out. Isn’t it sweet to change the monthly repayment amount into gas? So I told him that I bought a car to enjoy the model rather than the logo, and left after a few pleasantries.

I picked up my car in early June and have been driving for three months. Let’s share my feelings about using the car. First of all, the more I drive, the more I feel that I bought it right. Now my Changan PLUS is parked with those joint venture cars of the same level, and I always feel more elegant. The length, width and height of Changan PLUS are 4,730× 1,820× 1,505 mm and the wheelbase is 2,700 mm, but the length of this car is less than 4.7 meters, so the body of Changan PLUS is more slender and the interior space is more spacious. The shape of the new car is particularly exquisite, and the front and rear are equipped with penetrating light groups. The recognition of running on the road at night is also quite high, which is very high-grade.

When Changan CS75 PLUS first came out, I was particularly infatuated with its interior. Now it is a dream to buy Changan PLUS. The workmanship and materials used in the interior of this car are very much to my taste, and the car system responds quickly. The voice recognition system is really easy to use. When driving, you don’t need to be distracted, and you can control the skylight air conditioner and other equipment by voice. I used to feel that voice controls chicken ribs, but now it feels very practical. Moreover, this car is also equipped with a 360-degree panoramic image and a transparent chassis function. Although it feels a bit flashy, it is also practical, especially for novice drivers like my daughter-in-law and I, which really avoids many scratching accidents for us, and the camera definition is quite good. There are few such clear images in 200,000 joint venture cars.

I feel that the power performance of 1.4T Changan PLUS is not lost to that of 1.4T. In terms of parameters, this 1.4t Blue Whale engine can output 160 horsepower and 260N·m peak torque, and the book data is also better. Moreover, PLUS is matched with a wet dual-clutch gearbox, and 92 # gasoline can be added. With the difference of 30,000 to 40,000, I feel that I have bought a treasure.

Of course, to be honest, the shortcomings of this car are also objective. First of all, the fuel consumption performance can only be said to be average. I live in a small third-tier city, and the road conditions are not particularly congested. At present, the average fuel consumption of 3000km is 7.6 liters, which is really not as good as that of a joint venture car. Then the texture of the chassis is a little worse, not four-wheel independent suspension, so the comfort is average when crossing the bumpy road. But on the whole, Changan Yidong PLUS has a good cost performance and is definitely worth buying.

I like to mention Changan PLUS, but it is looked down upon by the driver. Everyone has different values. Besides, I really feel that the joint venture car is not high-end, which is just people’s traditional thinking. Today’s 100,000-class domestic cars are really fragrant, at least Changan PLUS is like this.

According to the latest data of SAIC passenger cars, Roewe’s new energy sales accounted for 45% in 2023, a significant increase of 29% year-on-year, among which the sales of hybrid vehicles increased by nearly 8% year-on-year. Mainly due to the continuous "boarding" of the DMH super hybrid system and the rapid "quantity" of the Roewe D7 DMH equipped with this system, the Roewe brand quickly gained a foothold in the hybrid car market. In addition, driven by Roewe D7 EV, Roewe iMAX8 EV and other pure electric vehicles, Roewe brand also achieved a substantial increase in sales in the high-end pure tram market.

The new kinetic energy generated by new technologies such as SAIC’s new energy technology base and Roewe DMH super hybrid system is pushing Roewe brand to leap forward.

Play the trump card of DMH hybrid technology and push the heavy SUV again this year.

With the advantages of energy saving, no mileage anxiety, and richer car use scenarios, hybrid vehicles have become a "dark horse" that can’t be ignored in driving the new energy auto market, and will usher in a new golden development period in the next few years.

Roewe, which has occupied the position of hybrid king for a long time, has once again taken the lead after more than ten years of accumulation, showing the trump card of refreshing the industry technical benchmark-DMH super hybrid system. The system integrates innovative technologies such as powertrain brain PICU and coaxial P1 motor pioneered by the industry, which will be the anchor point of Roewe’s "standing on DMH technology and breaking the game with long-term value" in the new era. Last year, Roewe released the "D Strategy", one of the cores of which is to "master the core technologies that affect the future development of the industry", upgrade the car experience with core technologies, and create long-term value for users. Facing the fully market-oriented new energy vehicle market, it is Roewe’s way to break through by firmly fighting "technology war" and "value war".

Roewe D7 DMH, a "super hybrid cloud car" launched in November last year, directly hit the competing products in the price range of 100,000 with the experience, quality and price of the B-class car, rewriting the value definition of the B-class car by the joint venture brand in one fell swoop, and relying on the advantages of the real long battery life of 1704km in winter, the measured fuel consumption of 3.4L km, and the industry-leading Yunsu intelligent cockpit, the order for listing in one month exceeded 10,000. Roewe D7 proves with strength that the more "involuted" the market is, the more it needs excellent technical strength, and DMH super hybrid technology is undoubtedly the basis for Roewe D7 to reshape the market competition pattern.

The strong support of new technologies has also enabled the Roewe brand’s hybrid products to be "new" quickly. It is expected that in March this year, the long-life hybrid SUV market will welcome Roewe D5DMH, the first SUV model of Roewe "D family". Roewe will continue to anchor the "trump card" and "heavy position" of DMH super hybrid technology in the hybrid market, and accelerate the replacement of "basic disk" fuel vehicles in the automobile consumer market.

Technology-driven pure electric quality upgrade, increasing the proportion of high-value products.

With the introduction of new products by major new energy manufacturers, the industry is moving towards full-scale market competition, and new energy vehicles will eventually return to the "challenge ring" that speaks with product strength, especially for pure electric vehicles with relatively higher prices, which have entered the "final circle" that is driven by technology to upgrade quality and experience.

Roewe D7 EV, a "rear-drive pure electric cloud car", with its safe and reliable quality and driving experience comparable to that of a 300,000-class high-performance car, jumped to the second place in the market segment of "pure electric car with a long battery life of more than 500 kilometers within 200,000" in Shanghai, the consumer vane of the pure electric car market. In addition, the Roewe D7 EV has sold more than 60% of the rear-drive flagship version with a price of 150,000 yuan or more, which shows that the market has a strong demand for high-quality pure electric cars.

For pure electric vehicle users, platform architecture, battery safety, cruising range, etc. are all the focus of attention. The Roewe D7 EV built on the exclusive systematic platform of pure electricity of "SAIC Nebula" is different from some hot-selling "oil-to-electricity" models in the market, and its original pure electricity architecture optimizes the utilization of internal space from the source, providing a 101L "unique" super-large front reserve box of the same class. On the battery safety that users are most concerned about, Roewe D7 EV adopts Ningde zero-combustion battery, which has five protection mechanisms. The ultra-thin "recumbent" battery with the leading energy density at the same level brings a pure electric cruising range of up to 610km, which is enough for daily commuting. Roewe D7 EV has improved the travel quality of users with its "true pure electricity" strength superior to its peers.

In addition, the Roewe D7 EV, which is beside the technology, has ended the embarrassing experience of the user’s "pure electric old man car", and proved that hundreds of thousands of cars can also talk about performance with strength. Roewe D7 EV is equipped with VGA six-in-one electric drive new three-electric technology. The maximum power of the motor is 145KW, the maximum torque is 310N·m, and the power is far ahead. In addition, the rear drive+five-link independent suspension further enhances the handling experience and greatly satisfies the user’s driving experience.

In 2024, it will be a crucial year for SAIC to implement the "Three-year Action Plan for the Development of New Energy Vehicles". Roewe will continue to increase the number of new energy tracks, anchor the core technology to break through, and take the real experience of users as the starting point, and continue to transform the technical value into user value, drive the core market with core technology, and continuously improve the travel quality and car experience of users. In the next three years, Roewe will launch nine new energy vehicles with the "D family" as the core, and realize full coverage of all categories from pure electric to hybrid, from compact to middle and advanced, from cars to SUVs and MPVs.
