Bernstein has stolen the advanced black China technology from domestic cars

In China's auto market, there is such a phenomenon. Fenqing generally thinks that the strength of domestic cars has been substantial, and it's not discussed to challenge the joint venture brand cars. The reason why no one buys them is that Chinese people worship foreign countries and are not patriotic. But is this really the case? Bernstein research company, a foreigner, has given you a lesson called "rational and objective" with the name of "big unloading eight yuan".

What does Bernstein research do?

Peter Bernstein founded Bernstein information company in 1919. Max & middot; Warburton, the European auto asset analyst of Bernstein company, revealed the manufacturing process and technical level of Great Wall Harvard and Geely Dihao. Geely Dihao EC7 and Haval H5 became test models, and the results surprised us.

Great Wall Haval H5

The welding consistency of the car body is poor and many welding spots are missing. The lack of set screws in multiple component assemblies reflects poor assembly quality.

In terms of suspension and brake, the corrosion problem occurred unexpectedly in a new car, and the design and assembly quality of other parts were also discounted.

Electronic systems - use of poor quality materials, lack of protection and use of poor quality fuse boxes.

The size of the radiator and air conditioning compressor does not match H5, and the design is also outdated.

Interior - poor quality, use of mismatched materials and unprocessed and poorly molded plastic parts, resulting in a rattling of the dashboard while driving.

The seat design is too complex, the cost is too high, and the production process is too labor-intensive.

Powertrain - equipped with a Mitsubishi engine from Shenyang, but does not meet Euro IV emission standards. The layout of the drive belt is chaotic. Great Wall's engine technology is still very weak.

The suspension of transmission -- H5 transmission and transmission shaft is very poor, which is also the reason why the transmission vibrates during test drive and hisses when shifting gears.

Geely Dihao EC7

The design of EC7's body front end is logical, but there are obvious problems in the welding of suspension tower top, including covering assembly defects with sealant at will.

Door -- EC7's door design is very complex, and the sealing is poor. The installation of sound insulation and silencing materials of the whole vehicle is very inconsistent.

After inspecting the door panel structure, fasteners and screws of emho EC7, interior design experts said that some of Geely's door panels are really inexplicable designs, as if they were designed by several groups of different people. Some parts are fixed by bolts, some by clips, and some by plastic welding, but none of them follow the logic or fixed routine.

Safety - this EC7 has reached the European ncap-4 star rating, but it seems that the high strength steel is not enough, which also weakens the rigidity of the car (the B-pillar is obviously bent in the crash test and may not be able to open the rear door).

EC7's suspension, braking and steering systems were criticized. These parts have poor design and general quality level, because the quality of engine bracket and rubber bushing is also very worrying, and engineers blame it on the rubber supplier.

According to other designs and configurations, the choice of gearbox is a bit strange. It can be said that they are using the gearbox of another car, which may not match the engine installation and power output. '

Suspension -- the rear torsion beam suspension of Geely EC7 is equipped with strut, which is the standard configuration commonly used in Japanese cars and French cars of the same class. Volkswagen and Ford have turned to more advanced multi link rear suspension, which has a lot to do with Toyota as the prototype of EC7.

Bernstein believes that it will take at least five years, maybe even ten years, for Chinese independent car companies to narrow the technology gap with international brands. To some extent, the progress made by Chinese automobile enterprises in recent years with limited resources is amazing. However, as emission regulations become more stringent and consumers become more mature and smart, their growth path will become more and more difficult. It is still unclear which Chinese auto company listed in Hong Kong will eventually become the leader of China's auto industry.
