's recent survey report pointed out that as consumers pursue higher and higher quality of modern life, people's consumption habits are also quietly changing. The past "appearance is in power" and "brand only theory" are no longer the factors that car buyers value. Today's younger generation of consumers pay more attention to the quality of their cars.
Regardless of the positioning and price, the word "reliable" is particularly important for users when buying a car. It can be driven for a long time without breaking down. This is the very simple demand of consumers for a car, especially a family sedan used for family travel. It is also based on this that the "100,000-kilometer non-stop test" has become a "big test" for whether a car has reliable quality.
The object of this test is the Buick Weilang Pro, which is equipped with the eighth-generation Ecotec 1.5T engine of SAIC-GM, which won the honor of the top ten engines of the "China Heart" in 2022.
"China Heart" is crowned, and the honor of Weilong Pro can be seen
The test vehicle this time is a Buick Weilang Pro Happy Edition purchased from a dealer (randomly shipped after anonymous purchase). As a new car, it is directly sent to the laboratory for 100,000-kilometer uninterrupted testing . After the test, the core power system of Weilang Pro was further disassembled, and the quality of Weilang Pro was "deeply analyzed".
Professional bench test, 100,000 kilometers of people rest without rest, challenging the limit of durability
That’s right, what is the performance of Weilong Pro after 100,000 kilometers, we decided to tear it down for you to see
[The performance is still as new after 100,000 kilometers, and the quality of Weilong Pro can be seen by users]
After successfully completing this 100,000 kilometers test, what kind of answers will Weilong Pro give in terms of acceleration performance and braking force performance? According to the China Automotive Media TOP Grade 100,000-kilometer ultimate durability quality challenge standard, after the vehicle has completed the mileage test of 100,000 kilometers, compared with the factory acceleration time level, the acceleration time of any assessment item does not increase by more than 5%, and the challenge is considered successful. However, the 100-kilometer acceleration time of Weilang Pro did not increase but decreased, which was 0.02 seconds faster than that of the new car, and the reduction range was between 0.2% and 3.2%, which can be said to be a good result.
Similarly, let's observe the braking performance again. According to the test standard: after the vehicle has traveled 100,000 kilometers, compared with the factory braking distance level, the braking distance of any assessment item does not increase by more than 5%, and the challenge is considered successful. For some brands of the same level, the braking distance is generally around 39-40m when the car is new. In comparison, the braking performance of Weilang Pro in the new car state is already a top student. After 100,000 kilometers, the performance has only increased by 1.6%-4.3%. It can be said that he was a top student.
In one sentence, the performance of Weilang Pro is still as good as new after 100,000 kilometers of uninterrupted testing
It is not easy to do this. Usually, the use cycle of our family car is about 6-8 years, and the mileage cycle of the whole car is about 100,000 kilometers.
This test ran 100,000 kilometers in just a few months, which greatly accelerated the wear and tear of the vehicle. Under this premise, the performance of Weilong Pro can still achieve the same level of performance as a new car. During the daily use of the car by the owner, the stability of the mechanical performance of the Weilong Pro is reassuring.
Another dimension of test results—in terms of comprehensive emissions, according to the TOP Grade 100,000-kilometer limit durability quality challenge standard, after the vehicle has traveled 100,000 kilometers, compared with the factory pollutant emission level, the increase of any pollutant emission does not exceed 35% and each index is lower than 50% of the national 6b limit value. The challenge is considered successful. We can first see that except for a slight increase in nitrogen oxides and particulate matter (PM) in Weilang Pro (increase of no more than 34%), other pollutant emissions have decreased. THC total hydrocarbons, Co carbon monoxide, and NMHC non-methane hydrocarbons have decreased by 13.63%, 9.35% and 4.5% respectively. All are lower than the national 6b limit by more than 50%. In terms of emission performance, the Weilang Pro after 100,000 kilometers still maintains a health level closer to that of a new car.
Secondly, the data shows that even after such a rigorous durability test, the emission scores of Weilang Pro are far lower than the National Standard VI (b) emission limit requirements.This means that our users basically don't need to worry about various problems including annual inspections caused by vehicles not meeting emission standards within a 100,000-kilometer service life cycle. The quality of Weilong Pro can be seen from this.
After the 100,000-kilometer test, Weilong Pro performed well in braking, acceleration, and emissions. For consumers, they are still concerned about the cost of the car. After the test, will there be any changes in the engine fuel consumption? Returning to the TOP Grade 100,000-kilometer test standard, after a vehicle has traveled 100,000 kilometers, the fuel consumption level of the ex-factory passenger car does not increase by more than 15%, and the challenge is considered successful. However, the fuel consumption of the Weilang Pro has dropped from 6.15L/100km in the new car state to 6.14L/100km, an overall reduction of 0.01L/100km, and the fuel consumption performance is even better. On the whole, in this 100,000-kilometer test, Weilong Pro demonstrated its strength with excellent results in these four challenges, proving its leading level in the industry. Friends who know
will ask, since it is a continuous and uninterrupted test, even if the performance is good enough, the durability of the engine gearbox must be sacrificed. After all, with such intense wear and tear, you won't see any serious wear and tear on the core components. That's right, after such a toss, it is also possible to "golden jade on the outside, but on the inside".
Therefore, after the 100,000-kilometer bench test, we also directly disassembled the engine and gearbox of the Weilang Pro and disassembled them to see in detail the wear and tear that everyone is worried about.
It can be seen from the disassembled engine and gearbox parts, including key parts such as engine timing chain, camshaft clearance, crankcase and gearbox chain, the wear amount is very low, and some parts are almost worn at the micron level. In addition, Weilang Pro also performed well in terms of "carbon deposits" and "oil pan sludge" that consumers are familiar with. It also means that they don't have to worry about engine or gearbox wear and tear during their daily car cycles, which can save a lot of maintenance costs.
From this point of view, the quality and reliability of Weilong Pro has indeed been tested, which is enough for consumers to enjoy a car experience with peace of mind, peace of mind, and peace of mind.
【High-tech production technology as the foundation, as well as strict system and intelligent factory guarantee】
The ability to successfully complete the 100,000-kilometer uninterrupted test and achieve such excellent results cannot be separated from the strong technical foundation of SAIC-GM Buick.
Taking the eighth-generation Ecotec 1.5T engine of SAIC-GM as an example, it has applied a number of innovative technologies, new processes and new materials. The engine is cast with aerospace-grade low-pressure precision sand molds, adopts separate cylinder head design and strengthened piston crank-rod, and applies advanced technologies such as 35MPa high-pressure direct injection system, electronic deflation turbocharger, and dual fast phase adjuster.
Take the increase in fuel consumption and abnormal engine noise that we usually encounter in "old cars" as an example. Usually, this is often caused by the wear of the piston in the cylinder. The piston of Weilang Pro's 1.5T engine adopts a new generation of nano-carbon fiber coating, and the piston profile design is independently designed by General Motors. Behind it is the hard-core and rigorous machine-level dynamic co-simulation technology from extreme cold to high temperature. And such excellent high-tech production technology, there are still many core components.
It is not enough to have a high-tech production process base, SAIC-GM also has a strict testing system and high-quality manufacturing. The engine of Weilong Pro has undergone very rigorous calibration and testing during the development process. The durability test alone has exceeded 20,000 hours, and the cumulative test mileage has reached nearly 5 million kilometers. Not only that, the SAIC-GM Wuhan plant that produced this 1.5T engine also has an astonishing level of intelligent manufacturing.
It is precisely because of this that Weilang Pro has achieved good results in the 100,000-kilometer uninterrupted test and reliable quality that reassures consumers.
is written at the end:
After successfully completing the 100,000-kilometer uninterrupted test, Weilang Pro received the "Extreme Durability Quality Challenge Certificate" issued by China Automobile Media. Weilong Pro has won new honors again. For consumers, the Buick Weilang Pro, which has passed the customs without loss for 100,000 kilometers, is a trustworthy and reliable choice.
Whether a car is durable or not is always one of the qualities consumers value. Weilong Pro successfully completed the 100,000-kilometer uninterrupted test under such short-term and high-intensity conditions, which is undoubtedly of great reference significance. We believe that Weilong Pro will become a reliable family car model for more Chinese consumers with its high-quality workmanship and solid reliability.
