As long as you pay a little attention to the car circle, you will find such a phenomenon, domestic cars are generally heavier than joint venture cars, especially in SUV models.
Comparison of the quality of Chinese and foreign models
For example, from the perspective of mainstream compact cars on the market, in addition to the new Toyota Corolla with TNGA architecture, the curb weight of the joint venture compact car is usually less than 1.3 tons, such as Xuanyi only 1238kg. The curb weight of domestic cars basically reaches 1.3 tons or even 1.3 tons, such as Lynk & Co 03 weighs 1454kg, which is about to catch up with the weight of compact SUV.
Looking at the compact SUV, in addition to the Toyota RAV4 based on the TNGA architecture, and the Honda CRV, the weight of X-Trail and Tuyue is less than 1.5 tons, while the weight of the domestic compact SUV is basically more than 1.5 tons or even 1.6 tons, and the gap is obvious.
The joint venture model is lighter because the body is lightweight and done well?
The current auto self-media has a general atmosphere, it seems to know a few advanced vocabulary to understand the car. I am very opposed to talking about the joint venture car is high-end, and talking about the light car is the body lightweight, it seems that only the joint venture car knows how to do the body lightweight. Body lightweight is the trend of automobile development, but we can't talk about body lightweighting out of the price. What is the premise of body lightweighting? Is it to ensure the strength and effect, if a material strength is the same or even higher, lighter weight, the price is cheaper, the car company is the head pumped without this material?
Therefore, the cost of body lightweight is often the cost of rising, like Jaguar XFL all-aluminum body, the body is only 1297kg, BMW M4 uses carbon fiber drive shaft, Audi A8 uses thermoformed ultra-high-strength alloy steel, which is called body lightweight. You have a car of more than 100,000 people, everyone uses the basic body lightweight program, why do you say that you are doing a good job of body lightweighting so the car is heavy? If the body of the joint venture car at this price point is done well, how to explain that Toyota's car has done heavier than other joint venture cars since changing the TNGA platform? And what about better security?
Why are domestic cars heavier than joint venture cars?
Therefore, at a price point below 300,000, if the domestic car is heavier than the joint venture car, in fact, it has nothing to do with the lightweight of the body, which is the following reasons:
1, the body frame material is more solid. I have always emphasized a point of view, car weight can not fully measure the safety, but in the price of less than 200,000, the car light safety is likely to do well. Moreover, it can be seen from the crash test of Zhongbao Research Institute that joint venture vehicles other than Toyota have not shown advantages in safety, but have constantly refreshed the lower limit.
2. Higher configuration. If you compare the joint venture car and the domestic car at the same price point, you will find that the gap between the two configurations is huge. Most of the configurations will increase the weight of some cars, in particular, the accumulation is not a small number, so the general high-end models will be heavier than the low-end models.
3. The allocation of joint venture vehicles has been seriously reduced. Reduced rear steel plate, anti-collision beam, sound insulation materials, spare tires, roof stiffeners, suspension materials... The way the joint venture car is reduced is strange and exhaustive, and the result is a reduction in the weight of the body.
Tail: 10 years ago the domestic car is indeed a "stupid heavy and bulky" typical, even the basic body lightweight is not good, have to use thicker steel to make up for the lack of strength, but in recent years, from the body lightweight point of view, the price of less than 300,000, the gap between joint venture cars and domestic cars is not large, the real difference is the tolerance of the Chinese people to joint venture cars and domestic cars, can you imagine what will happen to the machine throttle and stall door in domestic car companies? Can you imagine what will happen to a domestic car company like Volkswagen, where 200,000 models are hit by A-pillar B-pillar? The tolerance of Chinese people for domestic cars is too low, so that the fault tolerance rate of domestic car companies is too low. Finally, I would like to appeal to everyone to stop looking at domestic cars with the previous eyes, domestic cars are getting better and better.
