In the current fiercely competitive auto market, price involution has become the norm, which has also aroused heated discussions: have Chinese brand cars cut corners under price competition? It has become the focus of everyone's recent heated discussion. Understand the car's recent "Understand the Big Bang" program brought us an in-depth analysis in a timely manner. This time, the program selected two 100,000-level plug-in hybrid sedans cost-effective kings, BYD Qin L and Geely Galaxy L6 for dismantling and analysis, and the results are concerning.
From the dismantling of the Che Emperor, Qin L's dismantling shows the conscientious materials. The front anti-collision beam not only has a long width and high coverage, but also has 4 energy-absorbing boxes and additional auxiliary anti-collision beams; The passenger compartment adopts a flat floor, the structure is symmetrical, and the upper longitudinal beam is extremely long and closely connected to the main longitudinal beam, which can better cope with offset collisions;
The chassis adopts a flat design and a full-frame structure, which comprehensively improves comfort and safety, and the subframe is also patch-free, effectively avoiding resonance; The fuel tank is a 65L large-capacity iron fuel tank with redundant structural design; The engine has the characteristics of water-cooled EGR technology, application of engineering plastic intake manifold, large inclination angle of the inlet tract, long stroke design, high compression ratio and high thermal efficiency.
The gearbox is mainly electrically driven, with better motor structure, efficiency and heat dissipation, and lower failure rate; The electronic control board is large in size, multi-functional, high in integration, high in power density, and high in chip specifications; A large area of foam is used in the soft decoration part to effectively control noise.
The Geely Galaxy L6 also performed well. The rear anti-collision beam is made of steel material, the width is 1135mm, and the coverage rate is 60.5%; The front suspension is a steel lower swing arm, double-layer stamping, cast aluminum knuckle; The rear suspension is an E-type four-link with plenty of room for expansion, and the aluminum bearing housing makes the unsprung weight light.
It is worth mentioning that the double car is equal in the proportion of anti-rust technology and ultra-high-strength steel materials. The anti-rust process is no problem, and the proportion of ultra-high-strength steel is very high.
The content of this teardown fully proves that Chinese brand cars are not slacking off in the use of materials while striving to improve technology and reduce costs. Chinese brand automobiles are steadily moving forward in the automotive field with solid quality and enterprising spirit.
We have reason to believe that in the future, Chinese brand cars will continue to bring more surprises to consumers and shine more brightly in the global market.
