Today, the whole network is talking about the reliability of the car, let's talk about the core of the fuel car, but also the most critical chassis and control of the car. The chassis of the French car is known as the master of metaphysics among fans. Japanese cars are synonymous with excellent quality and reliability. What is the real situation? Let's start with the comparison between the new Peugeot 4008, the volume model of the French car, and The main sales force of Honda.
Chassis handling section 1: Body strength determines the upper limit and safety of handling
When it comes to vehicle chassis handling, the first thing that most fans think of is the suspension system of the car. But in fact, the rigidity of the body is the first element that affects the handling. If the stiffness of the body is not enough, in the high-speed emergency sideline driving, the pressure on one side of the body may be several times higher than the other side of the body, and the lack of rigidity of the body will cause the body to be twisted and deformed, resulting in the large potholes on individual national roads, the tailgate of the vehicle and the side door cannot be opened normally, bringing safety hazards.
The new 4008 In a dismantling program, the key A\B columns of the body frame, as well as the sill beams, were used in ultra-high-strength steel larger than the S-class 1400MPa. In line with the manufacturer's claim of 1600MPa ultra-high strength steel. During the dismantling, Honda Haoying did not find that the body contained any S-grade ultra-high-strength steel, as well as any A-grade high-strength steel. There are only entry-level steels such as B-class and C-class, which are not as good as the Honda micro-model fit.
In addition, in another "steamed bun" test that tested the strength and safety of the body, the new 4008 body has no deformation, and the front and rear four doors and tail doors can be opened normally. Honda Haoying's body deformed, and the tailgate could not be opened normally.
Chassis handling Section 2: Protection and spraying determine the quietness and durability of the car
The second key element of the chassis is the flat chassis and spray protection. At the beginning of the design of a good chassis, the flatness of the chassis will be considered to reduce the wind noise, wind resistance and passability of the chassis. And in terms of protection, a good chassis will use a full section of protective metal insulation tiles to reduce the high temperature exhaust pipe to the chassis of the hot baking. PVC spraying is also used to prevent rain from being corrosive to the chassis. Finally, on the outside of the entire chassis, an integrated shield is used to further reduce the wind resistance and noise of the chassis, enhance economy and silence.
Honda Haoying chassis on PVC spraying, especially on the two sides of the door near the bottom of the large side, there is a large missing. In the protection against the high temperature exhaust pipe, there is no full-section protection, and only some areas are provided with metal insulation tiles. On the protective plate of the chassis, Haoying also only uses a unique steel pipe protection in a few positions such as the fuel tank. As a first-line manufacturer, Honda is not ignorant of the chassis. For example, on the latest Fit, the chassis is flattened. The reason why Haoying is like this is that the body structure design is older, not that Honda is powerless.
The new 4008 adopts an integrated flat design in the chassis section, which can significantly reduce chassis noise and wind resistance. In the PVC spray protection, the new 4008 adopts comprehensive spraying, leaving no dead corners. In the exhaust pipe insulation protection, the full section of protection is adopted. In the armor protection of the overall chassis, an integrated flat chassis is also adopted, which can not only form a secondary isolation from wind noise, but also provide more comprehensive protection for the chassis.
Chassis control section 3: Structure and materials are very important, and the level of adjustment cannot be ignored
The chassis structure is the place that our fans most enjoy. At present, the mainstream models have several suspension structures. There are torsional beams and variable-section torsional beams in the non-independent suspension. Variable cross-section means that through the design of the variable section, the torsion beam should be hard where it should be hard, and the soft place should be soft, so that the wheels on both sides can avoid interference, weaken the interference of one side of the wheel on the other side of the wheel, and let one side of the wheel run freely. Independent suspension of the rear wheels is divided into three links, four links and five links. The highest number of five links of all because the wheels have free jumping in 6 directions. The role of the five-link bar is to restrain the jump in five directions, only to free up and down the direction of jumping, handed over to the spring and shock absorber to attract road runout.
Honda Haoying has only one chassis structure, that is, the front McPherson independent suspension and the rear 4 connecting rod independent suspension, corresponding to the Elk test score of 72Km/h. The new 4008 features two chassis structures. One is the front McPherson type independent suspension and the rear variable interface torque beam suspension. The other is the front McPherson independent suspension and the rear five-link independent suspension. The corresponding elk test became 74.5Km/h. The two different chassis structures reflect the chassis strength of french cars, in fact, Peugeot is the first car company in the world to use pneumatic tires, and the first car company in the world to use front wheel independent suspension on the car. Mercedes-Benz used independent suspension of the rear wheel after the front wheel suspension, and then the automotive industry began to popular independent suspension.
Chassis handling section 4: The reverse tire determines the handling safety, stability and silence
Tires are the most overlooked part of chassis handling, and it is also the easiest place for vehicle companies to save costs. Many models in the configuration of tires, basically say a set to do a set. For example, the flagship model is equipped with higher-priced tires to create selling points in publicity. In the entry-level volume model, it is equipped with low-end tires to save costs.
Honda Haoying's low-to-mid-range model is equipped with 17-inch Dunlop tires, and JD.com is priced at 450 yuan. Haoying top model is a 19-inch Michelin 3ST tire, and Jingdong is priced at 850. The tire gap between haoying high and low models is large. The all-new 4008 offers customized 18-inch Michelin e-Tingyue tires in low- to mid-range models, priced at 999 yuan by JD.com. The top model is a 19-inch horse brand LX SPORT tire, and JD.com is priced at 1299 yuan. There is a gap between high and low tires, but they are not large and are high-end tires.
Conclusion: So far, the new 4008 has the most leading links in the chassis material. The strongest S-grade ultra-high-strength steel is used in terms of body rigidity. The chassis is also fully flat, fully armored, fully painted, and fully insulated. The combination of tires also reflects the standard of materials that high-end cars should use. Haoying's performance is more general, especially when you ask Honda and Haoying to meet the standards of international manufacturers, you will find that it has a lot to improve.
