In recent years, China's auto industry has developed rapidly, and domestic brands have gradually emerged in the global market. BYD and Geely, as representatives of domestic brands, not only occupy an important position in the domestic market, but also have achieved remarkable results in the international market. However, as the saying goes, where there are people, there are rivers and lakes, and some people question whether domestic cars are sold so cheaply, is it cutting corners? In response to these questions, the program "Understanding the Big Bang" made a detailed comparison of BYD Qin L and Geely Galaxy L6, and spoke with facts.
This dismantling is very comprehensive, involving 13 items: front impact beam, rear impact beam, front suspension, rear suspension, anti-rust process, proportion of high-strength steel, passenger compartment, chassis, engine, gearbox, electronic control, fuel tank and interior. Through these teardowns, we can see a detailed comparison of the two cars in terms of materials, safety, electronic control system and powertrain.
According to the dismantling results, Qin L and Yinhe L6 are similar in the proportion of anti-rust technology and high-strength steel materials. In the eight items of front anti-collision beam, passenger compartment, chassis, fuel tank, engine, gearbox, electronic control and interior, BYD Qin L performs better; In the three items of rear impact beam, front suspension and rear suspension, the Geely Galaxy L6 performs stronger.
Specifically, in terms of safety design, the front anti-collision beam width of Qin L reaches 1460mm, the body coverage rate is as high as 76.8%, and it is equipped with 2 main energy-absorbing boxes and 2 auxiliary energy-absorbing boxes, as well as additional auxiliary anti-collision beams. This design greatly improves the vehicle's energy absorption effect and occupant protection performance in collisions, reflecting BYD's intentions in safety design.
The design of the crew compartment of Qin L is also very particular, with a flat floor design, the structure is symmetrical, and the materials for the main longitudinal beam, upper longitudinal beam and transverse reinforcing beam are sufficient. This not only improves ride comfort, but also enhances body rigidity and overall safety. In terms of chassis, Qin L adopts a flat, full-frame structure, which not only improves the comfort and stability of the vehicle, but also enhances safety. This design makes the vehicle more stable during driving, reduces the feeling of bumps, and improves the driving experience.
The Geely Galaxy L6 excels in the front and rear suspension systems, using high-strength materials to bring better stability and road feedback during driving. The design and choice of materials for the suspension system directly affect the handling and comfort of the vehicle, and Geely's efforts in this regard have clearly paid off. When driving the Galaxy L6, drivers can feel more precise control and a comfortable driving experience.
In terms of powertrain, Qin L's engine adopts advanced water-cooled EGR technology, which reduces emissions and fuel consumption; The gearbox is mainly electrically driven, which improves the transmission efficiency and reduces the failure rate. These designs not only make Qin L outstanding in terms of environmental protection and fuel economy, but also demonstrate BYD's leading position in the field of new energy technology. Qin L's powertrain performs excellently, ensuring ample power while minimizing its impact on the environment.
In terms of electronic control system, Qin L's main control board is large in size, multi-functional, high in power density and chip specifications, and strong in integration, which can meet the adaptability and reliability of vehicles in complex environments. Galaxy L6 is also very good in the electronic control system, "understand the car emperor" said that it is equipped with advanced electronic stability system and intelligent driving assistance functions, providing more convenience and safety guarantee for driving.
Overall, through this disassembly comparison, it can be seen that Qin L and Galaxy L6 have performed well in many aspects, especially Qin L dismantling shows conscientious materials, not only did not cut corners in terms of materials and technology, but surpassed the joint venture car in many aspects. The results of this teardown are also a powerful response to those who question the quality of domestic cars. Finally, with the continuous advancement of technology and the continuous expansion of the market, the competitiveness of Chinese auto brands in the global market will become stronger and stronger, and the future is worth looking forward to.
