如何选择家用汽车（How to choose family car） 如何选择家用汽车(How to choose family car) Car buying: what kind of measurement is the most scientific? To measure the quality of a car, technical performance is an important basis. Among them, power and economy are the main indexes. Of course, in evaluating the quality of the car, we must also consider the sales price and the personal needs of the consumers themselves. Nowadays, there are four popular indexes in the market. First: Power The dynamic index of vehicle is mainly expressed by the maximum speed, acceleration capacity and maximum climbing slope. It is the most basic and most important performance of vehicle performance. In our country, these indexes are obtained by the automobile manufacturer according to the national test standard and through the prototype test. Maximum speed: the maximum speed that a car can reach at a level, good pitch or cement road under no wind conditions. According to the provisions of our country, 1.6 kilometers long test section of the last 500 meters as the highest speed of the test area, a total of four times, take the average. Acceleration (acceleration time): the ability of a vehicle to increase its speed rapidly during driving. It is usually represented by acceleration time and acceleration distance. The acceleration capability includes two aspects: acceleration in situ and acceleration in overtaking. The parameters of acceleration in situ are introduced. Because of the acceleration of the car with good starting performance, overtaking acceleration is just as good. Standing start acceleration refers to the car from the stationary state after the start, with the greatest strength of continuous acceleration shift to top gear up to a certain distance or speed the time required, it is the most important parameter reflecting the automobile dynamic performance, the shorter the better. Second: Economy The economic index of automobile is mainly expressed by fuel consumption, and it is an important performance of automobile performance. In particular, the fuel tax is necessary for China to implement the fuel tax. The fuel consumption parameter refers to the amount of fuel consumed by the car running 100 kilometers (with the "rise") "L" as the unit of measurement. In our country, these indexes are obtained by the automobile manufacturer according to the national test standard and through the prototype test. It includes constant speed 100km fuel consumption and cycle fuel consumption. Constant speed fuel consumption per hundred kilometers: refers to the flat hard surface, the car in high speed with different speed driving this Duan Lucheng, from the first time averaged record of fuel consumption, you can get one hundred kilometers fuel consumption under the different speed of automobile. The fuel consumption of each speed segment is connected with a point, and it turns out to be an upward parabola, and the lowest point is the lowest fuel consumption speed, that is, the economic speed". Some manufacturers use this economic speed as a fuel consumption parameter, which is actually referred to as a reference value, because it is difficult for general users to achieve the same reason as the "acceleration time" mentioned earlier. Cycle fuel consumption: refers to a designated typical section of the car in constant speed, acceleration and deceleration and other three operating conditions when driving fuel consumption. Some also include fuel consumption under starting and idling conditions, and then convert fuel consumption to hundreds of kilometers. In general, the cycle fuel consumption and the constant speed hundred kilometers fuel consumption (designated speed) weighted average to obtain comprehensive oil consumption value, more objectively reflect the fuel consumption of the car. The fuel consumption is marked as "city fuel consumption" in some automobile technical performance tables, and the constant speed 100km fuel consumption is marked as "constant fuel consumption"". Third: cost performance The ratio of performance to price, refers to the product itself has the characteristics and functions of its single product price ratio, that is to decide the product according to the performance of the product value, this is the main measure to compare methods for product performance. Family car is a kind of special commodity of Jimei view, power, comfort and safety. Users purchase domestic cars, it is necessary to take into account the overall appearance, technical performance, safety performance and other factors. The poor safety of a car, even if the price is low, mature users never tempted; safety guarantee, technical performance and the car, even if the price is a little expensive, users will pay, because it is worth. Fourth: profit price ratio The comparison of interests is three-dimensional, not only to consider the performance, but also to meet the needs, but also pay attention to actual effect. For example, you need private daily scooter, safety and comfort should be the first choice standard; if you need housework and business vehicles, the three car is more suitable than hatchback car requirements. The ratio of performance to price is the value of the performance index, interest price than the practical value of efficiency; the ratio of performance to price to compare products as the core; the price than to their own interests needs as the core; the ratio of performance to price is relatively rigid one-way, two-way interest price ratio is relatively flexible. Through the comparative relationship between interest and price, we can find that in the choice of vehicles need careful division, comprehensive consideration of various factors: performance, quality, service, brand are indispensable. Automobile as the carrier of the movement of nearly twenty thousand parts and components, the performance is important, quality is the key, service is the guarantee, brand is value. You can't choose all of these, so you can only choose the most suitable one for yourself. Beware of five traps in car purchase We should remind consumers, in car insurance, deposit, price compensation and other aspects should pay attention to, beware of various traps of bad dealers. Watch the car business secret premium Mr. Wang bought a new car at a dealer last year. Because of the insurance trouble, he handed over the insurance to the dealer, and paid the premium for 3 years according to the requirement. This year, Mr. Wang's car accident, but when he found the insurance company for compensation, but was told that he only paid the annual premium, when the accident happened over the period of insurance, therefore cannot claim, Mr. Wang knew that his two years has been swallowed dealer premium. Mr. Wang's tragic experience is not uncommon, in the Consumer Association of Shanghai this year's fifth consumer tips, warned consumers to beware of dealers secretly seized premiums behavior. The consumers who entrust the car on behalf of the car can inquire to the insurance company through the telephone to determine whether the car has been insured in time, and also can directly insure the insurance to the insurance company. At present, the major insurance companies generally give preferential insurance to the insured by telephone and network directly to the insurance company. Deposit and deposit should be distinguished Now on the market of the new car, Mr. Li when buying a car is a bit hualiaoyan. Then in a dealer is said to have some heart, plus the car Miss assurances can be refunded, muddleheaded to pay 10000 yuan deposit. Only a week later, Mr. Lee also changed his mind and decided to buy another car, when he wanted to get the money, they had a head-on blow: "we had written but not refundable deposit, put it down in black and white, see it clearly!" Deposit and the deposit, two words one word, it has some differences in differences. According to the law, after the contract is fulfilled, the earnest money should be paid for or recovered. If the party who pays the deposit fails to perform the contract, he has no right to ask for the return of the deposit; if the party who receives the deposit fails to perform the agreed contract, he shall return the deposit twice. And the deposit and deposit meaning is very different, in the contract, if the deposit is written, one party default, the other party has no right to request its double return, can only get the original amount. Don't take credit for price cuts Look at the various brands prices have been diving, Miss Wu always indecisive, afraid of their own price fell just to buy a car. But not long after there is a dealer played "price compensation" banner, and her heart to buy a car, and agreed that if half of the car dealers will post the price paid back. Unfortunately, less than half a month, a friend of Miss Wu bought the same car, but cheaper than 10000 yuan. This let Miss Wu is very difficult to accept, to find the dealer for compensation was ablaze with anger, coldly saying: "we are saying if we only manufacturers prices, compensation to you, but we are cheap in none other promotions, not the price, of course, can not give you compensation." When prices fall again, Price compensation is really a tempting word. But the dealer is not a fool, they know the price of the manufacturer is unlikely, but the actual price is what they say, floating rate is large. So it's just a gimmick to make a price cut, and cheat you into the showroom, and the rest is easy to do. Basement lift Mr. Zhao spent big price to buy imported cars, put the car in the garage was told to the dealer to the inspection. Garage in the basement, no lights, the light is very dark, Zhao got the key after a little look at the appearance of the car drove away. Not long after the maintenance, Mr. Zhao found that the car's engine rusting, seems to have been very serious erosion. Mr. Zhao has always been very good at car maintenance, he believes that it can not be caused by their own reasons, and dealers also denied their negligence, the two sides into a long quarrel. When buying a car, consumers should carefully and carefully check the contents according to the contents of the handover, and there is no problem to sign. Once the user signs the defect, it is difficult to distinguish the responsibility from some quality disputes. - the second-hand car prices Mr. Zhang went to the second-hand car market to buy a second-hand car, car bug repeatedly assured him that the car did not what happened in collision. But then a repair, maintenance staff told him there was a deep dent in the old car engine, some key parts are not original, so it can be a major accident happened very sure this car. Mr. Zhang to find the bug has not seen the figure. Second hand car market transactions due to mixed cohabitation, the quality is difficult to guarantee, so it is not very understand the car consumers, buy the old car, or the car is best to take a friend to go to see, in order to prevent cheating. Shanghai auto parts industry association secretary general circulation water said that at present they are fighting for the implementation of a vehicle "card" system, make each vehicle maintenance could be recorded on the computer, when consumers buy a car, as long as the car can enter the license plate of the car repair know, fully guarantee the quality of the car.
