How to view the kilometer of a car: From data to practical guide
In the used car market or daily use, the vehicle's mileage (kilometers) is one of the important indicators to measure the condition of the vehicle. How to correctly view and understand the number of kilometers? This article combines popular topics and hot content on the entire network for the past 10 days to provide you with structured data and practical suggestions.
1. The core role of vehicle kilometers
The number of kilometers directly reflects the strength of the vehicle and is the key basis for evaluating the following aspects:
| Evaluation dimension | Low mileage (＜50,000 kilometers) | Medium mileage (50,000-150,000 kilometers) | High mileage (>150,000 kilometers) |
|---|---|---|---|
| Mechanical wear | The components are close to the new car | Consumable parts need to be inspected | Probably requires a major repair |
| Residual value rate | Maintain the original price of more than 70% | Approximately 40-60% of the original price | Less than 30% |
| Maintenance cost | Basic maintenance only | Replace tires/brake pads, etc. | Engine transmission maintenance |
2. 4 ways to check the number of kilometers
According to the recent hot discussions in the automotive forum, the mainstream detection methods are as follows:
| method | Operation steps | reliability | Applicable scenarios |
|---|---|---|---|
| Dashboard readings | Start the vehicle to view the total ODO mileage | ★★★ (May be tampered with) | Quick preliminary judgment |
| Maintenance record query | Through 4S store system or third-party platform | ★★★★★ | Used car deals |
| OBD Diagnostic Device | Connect to the on-board interface to read ECU data | ★★★★ | Professional testing |
| Tire/brake disc wear | Measure pattern depth and disc thickness | ★★ (Experience required) | Auxiliary verification |
3. Analysis of recent hot issues
1.Differences in mileage algorithms of new energy vehicles: The actual mileage of electric vehicles such as Tesla may be 15-20% less than that of the meter (due to different calculation methods of the energy recovery system)
2.Table adjustment phenomenon recognition: Data from a certain platform in 2023 showed that about 12% of vehicles in the used car market had mileage abnormalities, which can be judged by the following characteristics:
4. Reasonable mileage reference for different models
| Car Type | Average annual mileage | 10 years of ideal total mileage | Early warning threshold |
|---|---|---|---|
| Household scooter | 10,000-20,000 kilometers | 100,000-150,000 kilometers | ＞200,000 kilometers |
| Business car | 30,000-50,000 kilometers | 250,000-350,000 kilometers | ＞500,000 kilometers |
| Online car-hailing/taxi | 80,000-120,000 kilometers | More than 600,000 kilometers | ＞800,000 kilometers |
5. Expert advice
1.Combined with multi-dimensional verification: The China Automobile Dealer Association recommends checking at least 5 indicators such as engine compartment sludge and chassis rust.
2.Pay attention to the quality assurance policy: Most brands cancel core components warranty for high-mileage vehicles (such as >100,000 kilometers)
3.Dynamically evaluate value: Data from a used car platform shows that for every 10,000 kilometers increase, the residual value of the vehicle decreases by 0-3% (different models vary greatly)
By systematically understanding the information behind the number of kilometers, consumers can more accurately judge the vehicle condition and avoid car purchase traps. It is recommended to conduct professional inspections before major transactions to ensure that the data is authentic and reliable.
