As we all know, in recent years, the domestic automobile industry has been an indisputable fact, the major traditional brands and new power brands in order to seize the market or maintain the existing market is almost a sword, in the volume configuration at the same time crazy volume price, similar to BYD Qin L, Geely Galaxy L6 such entry-level vehicle prices are below 100,000 yuan, the starting price is 99,800 yuan.
For consumers, it is precisely because the price is involuted enough that the people can really have the opportunity to enjoy the convenience brought by the development of the automobile industry. At the same time, some media and car companies questioned the "involution", saying that behind the crazy involution is cutting corners, insufficient quality control, etc., and even named them on many occasions, calling on car companies to stop involution.
So the question is, is it really cutting corners and insufficient quality control behind the price involution of automobile brands? A few days ago, the "Big Bang Theory" column released the latest episode of the program, which carried out a comprehensive vehicle dismantling of BYD Qin L and Geely Galaxy L6, two models with a starting price of less than 100,000 yuan, which can be said to be a comprehensive response to "behind the crazy involution is cutting corners and insufficient quality control".
To put it simply, the vehicle dismantling is mainly divided into three major aspects: safety design, powertrain and workmanship, including front anti-collision beam, engine, gearbox, chassis, electronic control, fuel tank, passenger compartment, soft decoration, rear anti-collision beam, rear suspension and front suspension and other 13 subdivisions, let's look at them one by one.
Anti-collision beams
The front impact beam is an important part of the vehicle safety system, which can effectively absorb the collision energy and protect the structural integrity of the body and the safety of passengers. In this configuration, the Galaxy L6 front anti-collision beam has a width of 1345mm and a body coverage rate of 71.7%, which is quite good; The front impact beam of the Qin L has been increased to 1460mm, and the body coverage rate has reached 76.8%, plus two innovative auxiliary energy-absorbing boxes, as well as a secondary impact beam specially designed to protect pedestrians, the safety protection has been raised to a new height.
The rear anti-collision beam is to absorb and mitigate the impact of the rear of the vehicle, and to protect the occupants by conducting the impact force to the rear joint, so that the longitudinal beam and the passenger compartment can bear the main force and protect the safety of the occupants. In this regard, Qin L does not have a non-energy-absorbing box design, the anti-collision beam is 1250mm wide, and the coverage rate is only 42.1%, emphasizing the width and sacrificing part of the protection range, while the Galaxy L6 rear anti-collision beam is made of steel, with a width of 1135mm and a coverage rate of 60.5%, paying more attention to the protective area and material strength.
motor
As the core hardware of the car, the performance of the engine directly affects the operating efficiency, reliability and economy of the overall equipment. Both the Qin L and Galaxy L6 use water-cooled EGR and long-stroke engines for high efficiency.
The difference is that the engine of Qin L uses an engineering plastic intake manifold with a smooth inner wall, which can improve the stability of the intake air, and the three-way catalysis of one unit in the exhaust system can reach the national 6b standard; The Galaxy L6 uses a cast intake manifold and adopts a combination of three-way catalysis and particle trap scheme.
Gearbox
The gearbox is the core component of automobile power transmission, which ensures that the engine power is efficiently and smoothly transmitted to the wheels by changing the transmission ratio and transmission direction, so as to meet the various speed and power needs of the vehicle.
To put it simply, Qin L's selection scheme is mainly electricity, supplemented by oil, and adopts the structure of P1+P3, as well as the scheme of two sets of clutches and two sets of planetary gear sets, which is a scheme with a more mature structure and better stability, and has better performance in terms of comfort and fuel economy; Galaxy L is oil-based, supplemented by electricity, using P1+P2 structure, and the whole hybrid system is also very good.
chassis
As the cornerstone of the vehicle, the chassis carries the body and power system, which directly affects the handling, stability, safety and ride comfort, and is the key to the performance and quality of the vehicle.
The chassis of the Qin L and Galaxy L6 are both in a pure flat state to avoid accidental impacts. The difference is that the Galaxy L6 subframe is set up with a "patch" anti-resonance and adopts the traditional ingots beam structure; The Qin L adopts an innovative full-frame design, with no patch design to prevent resonance first, taking into account comfort and safety.
Suspension
The suspension is divided into front suspension and rear suspension, which are mainly used to connect the body and wheels, alleviate the impact of the road surface, improve the driving stability, ensure stable handling, and ensure the comfort and safety of passengers.
In terms of front suspension, the Galaxy L6 adopts a combination of double-layer stamped steel lower swing arm and cast aluminum steering knuckle, while Qin L adopts a single-layer crimped steel arm and cast iron joint scheme; In terms of rear suspension, the Galaxy L6 is based on the E-type four-link and supplemented by an aluminum bearing seat, which is a lightweight design scheme, and the Qin L also uses the E-type four-link, which is cleverly integrated into the large-capacity fuel tank design and focuses more on comfort.
Electrically controlled
The value of electronic control lies in the precise control of batteries and motors, improving power performance and battery life, and ensuring the efficient and stable operation of new energy vehicles. In contrast, the main control board of the Qin L electronic control system is integrated, the VCU is powerful, covering multi-dimensional control such as motors and brakes, and with Renesas high-end 32-bit chips in Japan, it has a high degree of integration, which is very good.
Crew compartment
The passenger compartment is mainly to protect the safety of the occupants, and at the same time, combined with the optimized design, to improve the driving comfort. The Qin L and Galaxy L6 passenger compartments are made of high-strength steel, and the Qin L lengthens the upper longitudinal beam directly connected to the main longitudinal beam, which can enhance the firmness of the front structure, and the steel baffle is added after cutting the front wheel arch, which is symmetrical on the left and right, which can further improve the offset collision protection.
Soft furnishings
Soft furnishings are mainly used to enhance the driving experience, create a comfortable environment, and highlight individual tastes, while protecting the interior and increasing the value of the vehicle. Qin L and Galaxy L6 have abandoned recycled cotton in terms of soft decoration and instead used a large amount of environmentally friendly acoustic cotton. Among them, Qin L is covered with a whole piece of foam, which can effectively reduce noise, and the same is true for firewalls.
Write at the end
Judging from the dismantling of the whole vehicle, BYD Qin L has better performance in 8 items, including front anti-collision beam, engine, gearbox, chassis, electronic control, fuel tank, passenger compartment and soft decoration; The Geely Galaxy L6 excels in the rear impact beam, rear suspension and front suspension; In terms of super-strength and anti-rust technology, the two cars are comparable.
But whether it is BYD Qin L, Geely Galaxy L6, these two star models with a starting price of less than 100,000 can be said to be quite conscientious in terms of configuration, in the real sense, to achieve "volume price, also volume configuration", in the same level of models are benchmark-level configuration exists, the so-called "crazy involution behind is cutting corners, insufficient quality control" is just an excuse for some brands to be unwilling to reduce prices. At the same time, it has to be said that the technology of Chinese brands is getting better and better, especially in the labor and materials of vehicles, and the progress is obvious, which is why more and more Chinese people choose domestic car brands.
