What car should I choose for my family?

On April 8, 2002, Shanghai Volkswagen's POLO sedan was officially put on sale. In order to promote POLO, the public published a lot of introduction articles about POLO, among which one article systematically and comprehensively introduced the characteristics of 02 POLO. I didn't have much experience at that time. Now more than three years have passed, from diving in various forums to becoming a polo enthusiast, I have some understanding of polo. I hope the above comments can help new prospective car owners to have a relatively objective understanding and understanding of POLO.

1, leading the engine system of domestic cars of the same class. The 1.4 displacement of model 02 Polo is imported from Germany, and the Germans are still very authoritative in terms of machinery. 1.4L/ 1.6L four-valve EA11transverse engine, belonging to German Volkswagen, is specially designed for compact cars. Aluminum cylinder block is matched with cast iron cylinder liner to increase wear resistance; Compact appearance: modular design of engine cover and air filter, all-plastic intake pipe and new pipeline exhaust system to improve intake and exhaust efficiency; The overall weight of the engine is reduced, the acceleration performance is improved and the fuel consumption is reduced. The valve drive adopts hydraulic bearing ball rocker arm structure, that is, RSH structure, which has smaller friction distance, lower fuel consumption, smoother intake and exhaust, and smoother engine operation! 1.4 engine is really the biggest bright spot, running smoothly and with extremely low noise. Never lose to a Japanese engine with low idle noise for show. The power is not high (55KW), but the torque (126NM) is the same as that of the 2V engine of Fukang 1.6, which can be achieved at 3800rpm, while the torque can reach 1 10NM in the range of1500-4000rpm. As for the aluminum cylinder block, it is not worth publishing a special book at present. Yida and Mazda 323 seem to be both! But the RSH structure is definitely a good thing, even golf and Bora's 1.6 and 1.8 can't compare! Coupled with the hydraulic support of the engine, it brings its low noise and low vibration! These undoubtedly increase the cost of the whole vehicle!

2. The electronic throttle E-Gas (as shown in "EPC" on the dashboard) adopts electronic control, which converts the throttle signal into an electrical signal, uniformly coordinates and manages the torque requirements of all aspects of the automobile, and optimizes the operation of the engine at each working point in terms of emission, fuel consumption and drivability. Electronic throttle E-gas is one of the measures to achieve low fuel consumption, which is only used in A0 cars and rarely used in A-class cars other than Volkswagen. The cost is naturally higher than the traditional cable throttle-one of the reasons-polo is expensive. Disadvantages: the reaction of throttle operation lags behind 1-2 seconds, and TX, who loves to drive fast, will not like it.

3.CAN-BUS system: POLO adopts the world's most advanced controller networking technology (CAN), including drive system, comfort system and information system. The system reduces the number of wire harnesses and the number of controller interface pins, and can realize online programming and diagnosis more simply and quickly, even the new function of multiple controllers working together, which makes the working state of the whole vehicle more stable and has more extensible functions. The benefits brought by these advances are rarely realized by ordinary car owners. Visible benefits-fewer wiring harnesses, fewer failures and safety hazards (such as spontaneous combustion) caused by poor contact due to aging of lines, and the most intuitive thing is that the ——POLO engine compartment is simple and tidy, which is comfortable to look at! Most notably, POLO can easily install safety and comfort equipment such as remote control, cruise control, ESP electronic stability, and driving computer by replacing the corresponding modules or upgrading the software. Unlike most A0 and A-class cars, don't even think about changing cars. Disadvantages: The cost of CAN-BUS is higher than adding some wire harnesses. The most exasperating thing is that Volkswagen does not provide similar personalized modification and installation services in China. I guess it's lack of confidence, worrying about all kinds of things and ghosts.

4.AG 150 automatic gearbox, the shift process is controlled by fuzzy logic. Intelligent control can shift gears according to different driving styles to obtain the best economy and power. An independent cooler is installed on the gearbox to cool the automatic transmission oil (ATF). The cooler is integrated in the cooling system of the vehicle, and the cooling is more reliable. Ignition lock device, you can pull out the key after putting in P gear and turning off the fire. Ignition can only be started in P or N gear, which effectively prevents misoperation. Let's start with the economy of AG 150. Self-weight of a car 1 140kg, 8-9L/ 100km (the most) for short distance in the city, and 6-6.5L/ 100km for long distance. Many 1.6 auto markets have at least 8 short trips and 7 high-speed trips. Yes, they have larger displacement, but many cars are lighter than POLO. There is only one saying that AG 150 was provided by a Japanese company for the public. I don't know if it's true or not, but it's definitely a good thing. The effect of smooth shifting is very small, and novices don't feel it at all. The ignition locking device is also one of the humanized designs of POLO.

5. Hydraulic clutch: multi-stage damping idle shock absorber and independent shock absorber, so that the noise and vibration of the whole vehicle are less in various idle States; Variable damping main shock absorber, to minimize the noise and vibration of the whole vehicle in floating state (maximum torque state); The friction plate is asbestos-free, lead-free and heavy metal-free, which is environmentally friendly. Not to mention environmental protection, the noise and vibration of the car in various States can be directly felt! The independent damping device also increases the cost.

6. McPherson independent suspension is adopted for the front and rear axles. Through continuous optimization, the driving comfort and stability are greatly improved, and the driving flexibility of small cars and the driving stability of middle and high-end cars are unified, which can bring supreme driving pleasure. POLO's suspension material is really unambiguous. You can tell by driving them. It does have some feeling of driving a mid-to high-end car, but only a little. Oh, POLO is POLO, family car!

7. Electro-hydraulic power steering system: an independent electric control steering system, which integrates steering controller, steering pump and liquid storage tank, transmits the vehicle speed signal through the vehicle speed sensor and judges the direction power. Steering assist performance is related to steering speed and driving speed. The lower the vehicle speed, the higher the steering speed and the better the power-assisted performance. Conversely, the higher the vehicle speed, the weaker the power-assisted performance and the heavier the steering wheel, so as to enhance the handling stability. This technology unifies handling flexibility and driving safety, which is the first application of this international advanced technology in domestic cars of the same class. This is one of the biggest highlights of POLO. Bora, Passat and other high-profile vehicles do not use safety equipment. Security has improved compared with others, and the cost has also gone up. POLO adopts very advanced hydraulic servo, which is power steering. This steering has many advantages, but when it comes to control, there is more important than it, and that is the sense of road. POLO's suspension and steering structure make the road conditions basically tell the driver through the vibration and feedback of the steering wheel, so that the driver can guess the road conditions according to his feelings and make corresponding driving style adjustments. Coupled with its suspension characteristics and excellent rear wheel tracking, driving this kind of car can feel that the driving feeling pursued by Europeans should basically be arbitrary.

8. Double-sided fully galvanized body, 12 years anticorrosion guarantee; Smooth appearance, good sealing, and the drag coefficient of the whole vehicle is less than 0.33; RPS positioning point reference system is adopted to ensure assembly accuracy, and the body gap is less than 3 mm; It not only lightens the weight of the car body, reduces the fuel consumption, but also increases the safety strength of the whole car. Many DXs have seen 1956 cars (including Sang 2000), and the door steel plate is completely rusted (the paint surface is not hurt, but it is rusted from the inside out)? POLO's four door sealing strips have definitely made great efforts-there is a whole circle of sealing strips on the door frame, in addition to a whole circle of sealing strips on the door, there is a sealing strip along the window glass on the upper part of the door. Look at the materials used in other A-class door sealing strips, and then look at the assembly accuracy of POLO and the uniform body (door) gaps everywhere, and you will have a clear concept of "exquisite car"!

9. A large number of composite steel plates are used, and laser welding technology and body bonding technology are used in a large area. The total length of laser welding reaches 65,965,438+0 mm, which exceeds the average level of middle and high-class cars in China at present, and enhances the rigidity and strength of the whole vehicle. The front panel adopts an assemblable modular structure, which reduces the cost and improves the assembly accuracy. The dynamic stiffness of the whole vehicle exceeds 42Hz, reaching the level of international middle and high-class cars, improving safety and sports stability. This is one of the biggest highlights of POLO. There is always a DX saying that POLO has a strong overall driving sense, first-class control and integration of people and vehicles. However, there is also the role that TX does not understand the use of laser welding technology. In short, the higher the rigidity and strength of the vehicle, the stronger the impact and vibration resistance of the vehicle body, which means that it is less prone to deformation. Have you seen the accident reports and pictures of Zhejiang POLO being firmly pressed under the container? If POLO didn't widely use composite steel plate, laser welding technology and body bonding technology, let alone the owner opened the back door to escape, that is, he was crushed into a meat pie on the spot and couldn't open the back door (because the body was seriously deformed). Do you remember the door of the old car? Those who have not been hit, the gap between the door and the door frame is getting bigger and bigger, and some have no strength or skill to close it. What is the reason? Low rigidity, deformation caused by long-term movement and vibration; The car body (door) is deformed beyond recognition by slight compression or impact. What is the reason? The strength of steel plate is too low! Not only the thickness, but also the strength of composite steel plate is higher than that of ordinary steel plate with the same thickness! What do car users value most? Safety first is definitely the best choice. It should be noted that for a car, comfortable configuration such as CD, speaker, remote control, leather, mahogany and so on. It doesn't matter, it can be supplemented later, but the safety of the car can't be changed.

I think this is the most conspicuous place for the public. A solid body and a solid chassis are the advantages of German cars. One of the technical highlights of Volkswagen is technology. Volkswagen's body technology should be in the forefront of the world. POLO adopts high-strength steel plate and double-sided zinc (imported from Germany, much higher than Fit domestic plate), so it still has a high residual value after driving for several years. In the used car market, the price should also be relatively firm. Of course, the most important thing is to feel more at ease when driving.

In addition, it is more excellent in body rigidity. It uses laser welding (this is also worth mentioning, and other interested parties are also discussing) and optimized solder joint positioning (not much higher than Fit manual welding), which is the robustness of the car body. You can have a look. The gap on the body of polo really reaches the level of a high-end car, and the gap on the body is not as small as you want. Due to the limitation of the rigidity of the car body, the car body will be constantly deformed when driving due to various external standing such as the road surface, so the gap such as the door is used for deformation allowance. If the rigidity of the car body is not enough, the deformation will be large. If the gap is small at this time, two adjacent steel plates will collide. Therefore, behind the physical gap is the support of strong body technology. (This is why Zhejiang POLO was not crushed by container trucks. )

10, double airbags, in which the co-pilot airbag has the locking function, and the dashboard has the status display of the sub-airbag to remind you to protect the safety of children in the front row. Forget it! Few A0-class cars are not double airbags now. In addition, the locking function of the 04 co-pilot airbag has long since disappeared.

1 1, the latest generation of ABS from Volkswagen, has strong expansibility.

12, which passed the most stringent European NCAP crash test requirements and reached the four-star standard, is the highest level of similar products in the world at present and meets the safety regulations and standards of any country in the world. It's a fairly high safety index, which is really good!

13, the third generation of electronic anti-theft system: the whole vehicle has the function of automatic key password identification, which can automatically identify when accepting the wrong password to prevent the car body from being stolen. The verification system is transmitted through CAN bus system, which increases the onboard code and improves the encryption algorithm, anti-decryption function and reliability. It is said that the encryption algorithm is higher than Passat. Is it difficult to get started with the advanced anti-decryption, or is it too expensive to maintain POLO, so it is difficult to find the next home if it is stolen? Anyway, I haven't heard that the domestic POLO was stolen so far. My car can't even guard against theft.

14, window with automatic anti-pinch function. When the window is closed, it can automatically sense the upper pressure and retract in time, reducing the harm to people caused by misoperation and protecting the safety of passengers, especially children. There is no doubt about the advanced function. Coupled with the one-button function of the front door, it can be said that it is the level of a B-class car. The operation is convenient and comfortable, the noise is very small, and it is completely a feeling of high blockage (compared with A6! ), the premise is naturally the increase in costs!

15, child safety lock: the front door control switch can control the opening of the rear door window at will; The back door is equipped with a child safety door lock. As long as the POLO driver turns it to the locked state in advance, once the back door is closed, it cannot be opened from the inside, which greatly ensures the safety of the back passengers, especially children, when POLO users travel for a long time. The child safety lock cannot be opened inside, but only outside, which can prevent naughty children from accidentally opening the door in the back seat and causing danger.

16, the front seat belt is equipped with internationally advanced mechanical explosive retractor, which can quickly feel the impact force and deceleration, automatically limit and contract, and protect passengers' safety.

17. Optimal pedal design for collision. In the case of serious collision, the brake push rod will break in time to prevent the transmission of shock waves, so the pedal will not rebound and protect the driver's feet. POLO is the first application of this international advanced technology in domestic cars of the same class. POLO has an optimized brake pedal that can be broken in the event of a collision. It is believed that according to the survey, most of the drivers' right leg and calf bones are broken in all frontal collisions. Of course, in the case of beautiful deformation of the cab, the reason is that during the collision, the driver will instinctively slam on the brakes, which is almost always used on his right foot in Delhi. Coupled with the huge pressure of the front collision, they gathered on his leg and caused a fracture, but pineapple can now avoid this situation.

In addition, POLO's oil circuit can be automatically cut off in the event of an accident to ensure that it will not cause other accidents.

18, the steering column has energy absorption function to protect the driver's safety.

19, front and rear disc 14 inch brake system: this equipment is used for the first time in its kind. The front wheel is ventilated disc with high quality, which improves the braking stability. This is one of the biggest highlights of POLO. China's A0 class is the only one adopted so far, and many A-class cars (like SUNNY, TIIDA, etc. ) neither! Very necessary safety equipment! Now POLO is all changed into front plate and rear wheel hub!

20. Anti-collision bars are built in the front and rear doors, which will absorb most of the energy in case of serious collision and protect the passengers in the car.

2 1, a brand-new integrated taillight, which is not only round and transparent, but also adopts the world-advanced double-bulb parallel device. When one of the bulbs fails, one bulb still works to ensure driving safety.

22. Under urban working conditions, the fuel consumption per 100 kilometers is 7.8 liters; At the same speed of 60 km/h, the fuel consumption is 4.6 liters. This public is still full of reality! POLO fuel consumption gives four sets of data at one time: 60km/h, 90km/h, 120km/h, and urban working conditions. The fuel consumption in urban working conditions (manual shift 7.8L/ 100km) given by it is very appropriate and even quite conservative. In actual use, TXs with comprehensive fuel consumption less than 7.8L/ 100km in urban areas abound! There are even about seven people. Unlike some cars, which only give the data of driving at a constant speed of 50 km/h.

23. Environmental protection technology: The spraying, sealing and protection of the car body cavity should use environmental protection materials as much as possible to reduce harmful chemicals such as PVC. Using other structural designs or alternative materials, the consumption of PVC is reduced by 3.3 kg ... PVC coating is removed from the chassis of the whole vehicle, which increases the protection of plastic plates, not only reduces the weight of the car body, but also protects the chassis components such as oil pipes and enhances the protection. You don't care about environmental protection, or you don't understand what benefits environmental protection materials can bring you, but you will never ignore the smell inside the car. Get in the car and feel it with your nose. You will know the difference between POLO and those Japanese cars and Korean cars!

24. The vehicle emission reaches the EU2 standard, and it can reach the EU4 standard with a little modification.

25. The position of the steering column is adjustable. The height of the front and rear seats can be adjusted to increase the vision and driving space of each driver. The blue backlight instrument can clearly transmit the driving dynamic information. The storage cover on the dashboard, the front and rear cup holders, the storage box under the front seat and the storage bag on the backrest of the seat are convenient for your needs and expand your space. The most noteworthy point is that the steering wheel can be adjusted back and forth, and the height of the front seats can be adjusted. At present, the steering wheel of most domestic A-class cars (such as Corolla and Excelle). ) can only be adjusted up and down, not back and forth, and the front seats of many A-class cars can only be adjusted up and down. POLO's four-way adjustment really makes it easy for every driver to find a comfortable driving position that suits him. There is also a front cup holder like a transformer, which can be suitable for cups of various shapes. This is a good thing. The storage box (small drawer) under the front seat is also very intimate, but unfortunately, the small drawer and height adjustment function under the co-pilot seat of 03 were given to the big lady by the public!

26. Bumpers, wide body trims, door scuff strips and rearview mirrors painted in the same color emphasize harmony and unity, and the whole vehicle is seamless, which belongs to the highest-level vehicle configuration of German Volkswagen.

27. Optimize the bumper structure to provide more reliable protection for the car body and reduce the insurance and maintenance costs of users. POLO's bumper is really strong, so it can be said that it will not lose to many B-class cars. Not to mention grade A or A0. Safe! It was expensive when it was imported earlier, but now the domestic price is not high, it looks about 300 meters. Besides, this item is basically paid by insurance companies. Is it okay?

28. The "seamless" body and bumper can be called "zero millimeter gap", which is not only beautiful and practical, but also meets the equipment requirements of mid-to high-end cars. This is one of the biggest highlights of POLO. This is definitely not the production line of Corolla, Brother Crow and TIIDA Gate! What do you mean by carving and pecking? It is not enough to just have a good impression on exquisite body technology. What it needs more is the rigorous attitude of making cars, the pursuit of perfect concept of making cars, almost harsh design ideas, and the guarantee of high-precision processing equipment (production line) and perfect quality inspection system. POLO's clearance inspection is not with naked eyes, but with special instruments. As far as the annual depreciation cost of POLO's production line is at least 5,000 yuan higher than those of Japanese Korean drama cars, can we simply compare the new price of POLO with Fit?

29. Interior: Plastic hanging technology, smooth surface texture of instrument panel, which enhances the aesthetic feeling and interior grade. The interior of the roof is made of PUR material with 3mm soft foam knitted material, which is not only beautiful, but also has better texture. The seat is made of plane elastic woven fabric, which is better, smoother and more comfortable than the commonly used woven fabric after advanced technology treatment. The central passage extends to the back seat with cup holder. The quality of the whole interior is equivalent to that of contemporary A-class /B-class cars. There is absolutely nothing to say about this! Quite a few car owners (especially women) fell in love with POLO at first sight through exquisite interior workmanship. Unfortunately, high-grade configurations such as dashboard with plastic lining and interior materials on the roof are only available in luxury models!

30, blue backlight instrument, red pointer, easy to drive at night.

3 1, night reading light, front door with car light, door warning light. At present, there are only two luxury boxes for POLO night reading lights, and the front door lights and door warning lights are only on luxury ones. There is only a lampshade without a light bulb under the comfort (the light wire may not be connected).

32. There are three sun visors in the front row, left, middle and right, which effectively block sunlight from different directions. The other two left and right sun visors are equipped with illuminating cosmetic mirrors. At present, the third sunshade in the middle of POLO and the mirror lighting behind the sunshade are only luxury and three boxes of comfort.

33, the roof handle with shock absorption, turnover, automatic slow recovery, reaching the level of high-end car configuration. Today's POLO has only luxury models and three-box comfort models.

34. The detachable front decorative panel can be disassembled at will, and the built-in hidden traction hook socket is beautiful and practical.

35. Built-in 12V power socket in the trunk is convenient for your mobile life. However, model 03 was completely cancelled from the beginning!
