At present, "safety" has become one of the key words of automobile products, just like innovation and intelligence. Major car companies are paying more and more attention to the safety of their models, and some high-end models with higher prices list "safety" as the main selling point. However, a thought-provoking question comes: Is the more expensive the car, the safer it is?
It took half a year, knowing that the car emperor selected 30 models of 60 popular cars that are popular in the current market and have high attention, up to 1.6 million yuan.Car, an entry-level car with a class of 50,000 yuan, has been tested for 90 times in three projects, including 64 km/h 40% overlapping frontal collision, 80 km/h 70% overlapping rear-end collision and 56 km/h 30% overlapping drilling truck collision.

The test results show that the higher the price, the safer the vehicle is. Among the tested models, the models with a price of 300,000 ~ 500,000 yuan have the highest proportion of G (excellent) and A (acceptable) evaluations, even better than those with a price of more than 500,000 yuan. For example, in the 56 km/h 30% overlapping drilling truck crash test, the safety guarantee of most models is lacking, even cars are no exception.
"High-priced vehicles can often provide more safety configurations, such as multiple airbags, high-level body stability systems, automatic driving assistance systems, etc., but this does not mean that vehicles have higher safety in all cases." A vehicle technology R&D engineer told national business daily that vehicle safety depends more on the technical level of car companies.
In this test, Master Che also found that the main factors affecting vehicle collision safety are body materials and safety structure design. For example, the combination of side impact protection system (SIPS) and side airbag in Volvo Cars can significantly reduce the serious chest injury of passengers in side impact, with the reduction rate as high as more than 50%.
Although the higher the price, the safer the car is, but it can also be used as a reference index to measure the safety of the car to some extent. Judging from the results of this test by Che Di, the overall collision result of vehicles below 100,000 yuan is average, because the airbags, air curtains and seat belts of vehicles below 100,000 yuan are pre-assembled, and these configurations are generally difficult to complete, and the strength of body structure steel will also be subject to the cost.
Compared with foreign brands and joint venture brands, self-owned brand models were once labeled as "low quality and low price" because of their late start, weak foundation, lack of mature manufacturing system and solid market foundation, but now this label is being torn off.
Judging from the test results of Know Car Emperor, China has made remarkable progress in automobile safety. Especially in frontal and rear-end collisions, many domestic brands rank high in body structure, occupant protection and emergency rescue, andPower of the carNo fire occurred.
According to the results of 2024 China New Car Quality Research (IQS) released by global market research institute J.D.Power, the quality of self-owned brands in the driver assistance category tends to be stable in the past three years, and their leading advantages are also obvious compared with mainstream international brands and luxury brands.
With the increase of market share, independent brands have increased their research and development in product safety. For example, recently, China FAW obtained a patent for a technology called "a vehicle collision warning method, device, equipment and storage medium". The core of this technology lies in how to realize efficient collision warning and ensure that drivers can get information in time in case of emergency, thus effectively reducing the accident rate and protecting the safety of passengers in the car.
The reporter noticed that most of the models currently on the market will be equipped with active safety configurations such as automatic emergency braking system, lane keeping system and electronic stability control system, as well as passive safety configurations such as side airbags and side air curtains.
However, even if the active and passive safety configuration of the vehicle is high, the driver must maintain good habits during driving, fasten the safety belt while controlling the speed and safe distance, and especially keep a safe distance from the big truck.
