So what is a car? What kind of car is a good car?
Automobile is mechatronics, which combines classical physics, electromagnetism and even quantum mechanics.
When buying a car, everyone wants to buy a "good car". So what kind of car is a "good car"? This is a bit controversial: some people say that a beautiful car is a good car, some people say that a car with good power is a good car, some people say that a car with good fuel economy is a good car, and of course some people say that the most expensive car is a good car ... Ask a thousand people and there will be a thousand answers, just like every man has different aesthetic standards in his heart. So is there a standard to evaluate the quality of a car? The answer is yes. The evaluation of a car is mainly from the following aspects: the dynamic performance of the car-the maximum speed of the car, acceleration time, fuel economy-the ability to complete the unit transportation workload with the least fuel consumption, handling stability-the ability to respond to the driver's steering instructions and resist various disturbances that change the driving direction and maintain stable driving, braking-the ability to slow down and stop as needed, or the ability to maintain a certain level when going down a long slope. Ride comfort-can avoid vibration and impact during driving, make people feel uncomfortable, tired, even damage their health, or damage goods, passability-the ability to pass through various bad roads and roadless areas at a high enough average speed and overcome various obstacles. However, no car can do this perfectly. In fact, a car is a balanced mechanical product, which should be adjusted according to its positioning and the people who use it. For example, if a car wants good power, it must sacrifice certain economy; If you want good handling, you must sacrifice some comfort; The high chassis and good passability will affect the ride comfort of the car to a certain extent, and so on. Therefore, the perfect car does not exist. When we buy a car, we must first make clear our actual needs: if we mainly drive on urban roads, we should pay more attention to the ride comfort and fuel economy of the car; If you often go out to road trip, sometimes you need to go off-road. Pay attention to the power and passability of the car. If your driving style is radical and you like to drive fast, you should pay attention to the power, handling, braking and so on.
I think buying a car is a bit like dating someone. Who is better? There are endless beauties and endless cars in the world. "Radish and vegetables, each has his own love." There is no best, only what suits you best.
In my opinion, there is not much difference between good and bad cars after government approval. It is important to know how much rice you have in your pocket and where to buy this car. A car that meets your needs is actually a good car.
At present, it is hard to say which car is good or not in the domestic market. It is written in black and white, and you get what you pay for. For the consumers of this kind of car, the subjective preference is actually greater than the quality of the car itself, that is to say, many consumers who can buy this kind of car are actually more emotional consumers. For most consumers, to spend more than one million yuan on a family car, the richer the better, or the more versatile the better. It is best to have a brand, space, motivation, quality and passability. Million-class SUV will be the choice of most people, and it has more advantages than its peers.
My car purchase budget is about 6.5438+0.5 million yuan. There are many SUVs at this price, such as Porsche Cayenne S, Land Rover Range Rover Executive Edition, lexus LX570, Mercedes-Benz GLE/GLS/ Big G, BMW X5/X7, Audi Q7 and so on. These cars are all in my sight. I have been to 4S stores many times for test drive comparison. I think the designs of Land Rover Range Rover Executive Edition, lexus LX570, Mercedes-Benz GLS/ Big G and BMW X7 are all magnificent, and unpaved road conditions are their world. People who have business needs or run a lot of unpaved roads prefer it, but the flexibility and acceleration of urban driving are not as good as those of medium and large SUVs.
I am not a businessman. I like to drive my own car. I bought it and drove it myself. Driving and paving roads in the city is my main battlefield. Even in "On the Road", I didn't want to ride down the mountain in a million-class car, so I gave up. Mercedes-Benz GLE and BMW X5 are both good cars with good sportiness and handling. They are high-end medium and large SUVs with luxury, off-road and highway attributes, but the rear seat is generally comfortable and the brand effect is one level lower than that of Porsche, so they also gave up.
The last thing that caught my attention was the Porsche Cayenne S. Her face value, performance, interior, control and other aspects are balanced and very individual. I placed the order on June 20 19. Because the national fifth emission cannot be licensed in Shenzhen after July 20 19, I can only wait for the manufacturer to change the engine emission standard to national sixth, with a quota of 1 in 2020 and arrive at the store in April 2020.
After booking a car, I often check the production progress and shipping situation of the car online. After a long wait of 10 months, the sales guy in the 4S shop finally informed me that I could pick up the car and finally married her home in April 2020.
This mahogany metallic paint Cayenne S adopts a brand-new 2.9T engine, with a maximum power of 324KW(440 HP), a maximum torque of 550N.m and a maximum speed of 265 km/h. The front through-mesh and split headlights are highly recognizable, full of personality, elegant and dynamic body lines, a strong sporty atmosphere, a well-defined tail, and a very good through-taillight lighting effect, which looks very classy as a whole. Luxury and technology coexist in the interior. The overall workmanship materials are impeccable, and the central control panel feels excellent. The size of the central control panel is 12.3 inches, which supports carplay and navigation. The touch buttons in the central channel are quite scientific and technological. The symmetrical design of the instrument panel of the fifth barrel is calm and atmospheric, and the materials are basically wrapped in soft materials, with a solid and delicate texture. A quartz watch on the center console gives people a noble temperament and makes people fondle it.
I don't think Cayenne S is a patent for young people, and we middle-aged and elderly people can easily control it. When I really got into my car, from the moment I started the engine, the exhaust pipe made a unique rumble, giving people a feeling of blood spurting. The sense of acceleration and sensory stimulation brought by stepping on the accelerator is simply a crazy beast! Its seat leather and wrapping are absolutely superior, and the leather texture of the steering wheel and seat is high-quality leather, which feels very delicate and comfortable. The front seat is equipped with 18-way seat adjustment function, with leg rest adjustment, and the support performance is in place. The wings on both sides can ensure the stability of the car body in some fierce driving. There is plenty of space in the back row, and the independent air conditioner, charging interface, storage compartment and panoramic skylight all meet my expectations. The front and rear position of the seat and the backrest angle can be adjusted to make more room for the trunk.
When encountering speed bumps or potholes in urban road conditions, the chassis can easily cope with bumps. What the rear passengers can feel is that they know it may not be flat, but they will not feel uncomfortable. This is due to its air suspension system, which has the ability to dissolve all kinds of impacts invisibly by softening rigidity. This system seems to have some intelligent processing ability, and it can still show the vibration filtering ability similar to the standard mode when encountering continuous bad roads. In the case of intense manipulation, no matter which mode, its support force in corners is "lever", which controls the roll of the car body in a small range. The chassis control system mainly increases the active electromechanical stability link, which further improves its anti-roll ability in corners and gives people confidence and motivation to challenge every corner when driving.
During the COVID-19 epidemic, highways were free. After filling up the gas, you went to run on the expressway. The salesman told me that the engine speed should not exceed 3000 rpm in the first 3000 kilometers. However, on the highway, it is difficult to drive slowly. The power it carries, there is no need to doubt whether it can bring you pleasure. In normal mode, the power can basically be on call, while in Sport and Spot+ modes, it is very violent. It is already a light throttle and is about to rush forward, giving a feeling of pushing back. The so-called ghost killing is vividly reflected. Not only is it excellent in power, but it is also perfect in power, comfort and off-road performance. Especially when the speed is above 100km/h, the ability to accelerate again is still very strong, and it is easy to exceed the speed limit of 120km/h, so it is better for me to set a speed limit reminder if I like to pursue speed pleasure. While having a strong road driving ability, it has not given up the comfort that luxury brands should have. It brings me the pleasure of driving a sports car, and it can also take me farther and more rugged. After all, its front is printed with Porsche's golden Logo.
This twin-turbocharged V6 has two most commendable points. One is that its response is really fast, in any speed range, and the other is that it is really super quiet to drive. I chose to install a private double-decker sound insulation glass, and my performance in driving mute is quite amazing.
Braking gives me real confidence. No matter how fast I drive, I can feel my fist as soon as I step on it, which is definitely the performance of a performance car.
If there is anything unsatisfactory, it is the storage capacity in the car. There is basically no storage space in the central armrest, only one mobile phone wallet certificate can be placed, and it is no problem to put two bottles of mineral water in the water cup holder. The storage bags of two cab doors barely hold three bottles of small mineral water, but it is not easy to take them out. Only small objects can be put in, which really doesn't have much effect. It is also possible to put a mobile phone or a small umbrella in your hand. The storage bag in the back row is similar.
Some people say that buying a car is easier than maintaining it. Judging from my past experience of owning three cars, it is not difficult to keep a car.
My concept of car maintenance is: cars are used for self-help, not as treasures, but as slaves.
In terms of aesthetics, on the basis of giving away the driving recorder and window film, this car only bought a set of German original foot pads in the 4S shop, found the owner of the 4S shop to grind them hard, and gave a Zhang Deguo original trunk mat, and other items didn't cost much. In daily use, some people will feel distressed when they see a little scratch on the car, but it is completely unnecessary. There will inevitably be bumps in the car body. When I used to use the car, I always waited for a certain number of scratches before I repaired it together. I think cars with a million yuan or more are bought after matching. I don't wear clothes, don't add seat covers, and don't make any modifications. I haven't bought 20 thousand pieces of clothes for my parents. Why should I wear more than 20 thousand car coats? The seat is already good leather. Why do you want to cover it with a cover that is no more comfortable than her? Porsche engineers have scientifically designed and manufactured this car, so why did they modify it?
In terms of fuel consumption, go to the designated gas station to buy a card, recharge it once 1000, add 95 # gasoline, and the fuel tank does not add any additives. The first time I refueled 87.65 liters (90L fuel tank), the market price was 5.99 yuan /L at that time, and the prepaid card I bought was 4. 17 yuan/L. When I filled up a tank of oil with 365.5 yuan, I drove 8 10 km on the urban road, and the average fuel consumption per 100 kilometers 10.82 liter was converted into oil. It seems that this 2.9 V6 S twin-turbo engine is not only powerful, but also has made great efforts in fuel economy.
In terms of insurance, as a veritable old driver, I only need to buy compulsory insurance 950 yuan, travel tax 800 yuan, third party liability insurance (including deductible) 2549.73 yuan, a ***4300 yuan, and other types of insurance are not needed.
In terms of maintenance, most of the spare parts can be purchased by themselves, and they can be replaced in Porsche specialized shops only by paying labor costs. My annual spare parts and working hours budget is about 12000 yuan.
In terms of car washing and parking, in addition to car washing and parking on the highway (the budget is 2000 yuan a year), we have our own independent garage, which can be parked for car washing at ordinary times. I like to keep my car clean inside and outside every day. When you get home late, you have to wash your car yourself to ensure that the car is clean and hygienic when you leave the car the next day. Washing your own car is a pleasure, just like a sport. At the same time, pay attention to obey the traffic laws and regulations, drive and park according to the rules, and try not to generate too many traffic fines (the budget is one year 1500 yuan).
To achieve the above, the annual expenditure is about 32,000 yuan, so it is not difficult to maintain a car.
