Why does the service life of luxury cars far exceed that of ordinary cars?

Hardware cost:150,000 corolla and1500,000 BMW 7 Series (parameter | picture), the primary hardware is far from enough. External tire size, hub size and body size; Stealth chassis materials, engine technical level and so on. There is not much difference just because of the different tires, but if the price of the car is1002 million, that is to say, the quality of the car has improved in all aspects, the whole result is far from perfect.

Car quality: car quality: no matter how expensive a car is, it is nothing more than the chassis of the engine gearbox. In terms of production cost, a civilian car is hard to be expensive. The definition of luxury car is actually two pieces, a good mechanical foundation and a luxurious carriage. The oldest luxury car, looking for the best materials for car seats and central control door panels; Later, everyone considered whether to sit comfortably or not, which is ergonomics; What we are looking for now is to use high technology and good materials. In the final analysis, it is to seek the quality of the car that people can directly feel.

Adjustment skills: Adjustment skills are the most valuable for functional vehicles that attach importance to driving and handling. Small to the steering wheel style scale, seat planning, rearview mirror orientation and other details; The rhythm of exhaust sound, aerodynamics, and black technology of electronic systems are all hidden costs. For example, Cartham has been concentrating on the rigidity of the frame for decades, and now an iron frame can sell hundreds of thousands; Ferrari spent hundreds of hours adjusting the exhaust sound; Mazda MX-5 (parameter | picture), Honda S2000 (parameter | picture) In order to get the front and rear weights of 50:50, we also discussed the human body shape and the weight of common drivers.

Selection of car-making materials: Today's car-making materials can be roughly divided into steel materials, aluminum materials and carbon fiber materials, and magnesium alloy materials are under development. Different weights have different safety performance. At present, the direction of automobile development is to take the light-weight route, so more aluminum and carbon fiber materials are applied to the body. On the premise of ensuring body strength, many high-end models have introduced all-aluminum bodies like Tesla, Cadillac CT6 and Audi A8.
