As an executive car, Wan Feng believes that the first model should be stable, not advanced but stable and safe.
This car has very high requirements on safety.
Of course, there are special safety requirements for vehicles carrying government officials.
Therefore, Great Wall vehicles use a non-load-bearing body.
You read that right. While most current sedans are developing towards load-bearing bodies, this Great Wall model uses a non-load-bearing body.
Nowadays, except for off-road vehicles and SUVs, there are not many cars with non-load-bearing bodies.
The simple explanation of a load-bearing body is that it has a chassis frame like a truck.
The load-bearing cars that are popular nowadays do not have body beams.
The core components of non-load-bearing vehicles such as the engine and transmission are placed on the vehicle frame, which is the foundation supporting the entire vehicle.
The advantage is that it can reduce the bumpiness of the vehicle because the chassis is strong. At the same time, when the vehicle collides, the frame can absorb the impact force, which is safer.
Some people say that a monocoque car has better flexibility and is safer than a non-monocoque car.
This is all nonsense, just talking nonsense with open eyes.
It is hard to say whether this view can be realized in the future, but at least for now it is nonsense.
Within the limit, your car's body can indeed be extended and retracted when it hits a wall, but if you try to hit a wall at high speed, when the collision force is greater than the extension limit of the body, your only fate is to turn you into a discus or a pile of wreckage.
Because of the existence of the frame beam, the non-load-bearing body can greatly absorb and alleviate the impact caused by the collision, and the safety factor is naturally greatly improved.
Of course, there are advantages and disadvantages. The non-load-bearing body has an additional beam, which increases the overall weight of the vehicle and the corresponding fuel consumption. At the same time, the center of gravity of the vehicle is also increased due to the presence of the beam, making it difficult to make sharp turns.
However, these things have undergone subversive transformation in the hands of Nanwan Micro Drivers and have been weakened to the greatest extent.
First of all, Nanwan Group has the best steel in China, which can be used to build warships.
The frame beams made of this kind of steel are more than one-third lighter than those made of ordinary fine steel, while having the same strength.
In this way, the extra weight is not much compared with a load-bearing body.
Because they are building an administrative vehicle, a higher center of gravity is not a problem. The most important thing when carrying officials in the car is safety first.
Can you drive like the wind? That means you don't want to do it anymore.
As for emergency turns, there is no such thing.
This car not only adopts a non-load-bearing body, but also the anti-collision beams on both sides of the body are also made of new design and special steel.
If this car undergoes a crash test and gets excellent results in five or six crash items, it will be a piece of cake.
After the prototype car rolled off the production line, Wan Feng measured the height of the car. It was indeed five centimeters taller than an ordinary car, but because its body was longer than an ordinary car, it was not easy to notice at first glance.
This prototype car did not leave the workshop. It was directly put on the test bench after coming off the production line. It will undergo no less than 500 hours of testing on the test bench to test its performance in all aspects.
Wan Feng personally watched as the prototype vehicle was placed on the KC test bench for the entire vehicle, where the test workers connected a mess of wires to it.
After the KC test is completed, drum and vehicle tests must be carried out.
Once these projects pass the test, it will be time for field trials.
After the test started, Wan Feng looked at it for a while and then shifted his attention.
There are other components being tested in the test workshop.
It was a new engine, humming softly on an engine test stand.
"This is our newly developed 482 engine, prepared for future 2.0-liter cars. If we use a new turbocharger, the displacement can reach 2.2."
The person who explained to Wan Feng was Zang Junguan, the chief gasoline engine pilot of Nanwan and a famous Tibetan military officer in Nanwan.
"This engine has been tested on the test bench for a long time. It's almost 1,500 hours now. When it reaches 2,000 hours, it will be installed in a vehicle for testing. It was originally intended to be installed in an SUV, but now it will probably have to be tested on a Great Wall first."
On another test bench, there is an engine that is obviously longer than this 482 engine, but it is not being tested and is just sitting quietly on the test bench.
"Which engine?"
"That one is also a new product, an inline six-cylinder. It's been on the test bench for dozens of hours. There's a problem that needs to be checked."
It is normal for a new engine to have problems, and it would be abnormal if it didn't.
"In a few days, a V6 engine will also be put on the test bench for testing."
Wan Feng knew all about these projects, and he approved the research funds personally. There are a lot of engine projects this year, including seven or eight diesel and gasoline models, and the research funds alone are more than 500 million yuan.
More than 500 million in 1999 is definitely not a small amount of money.
His investment in engine research is enough to put anyone on the rich list.
Wan Feng came out of the workshop and suddenly remembered that he didn't know whether he had bought firecrackers or not. He quickly picked up the phone and called Zhou Liming.
"Hey Liming, did you bring back the firecrackers you set off last night?"
"Brother-in-law! What do you mean by asking this? I've been doing this kind of thing for many years. How could I forget it?"
Little guy! Ever since we officially became brothers-in-law, his tone has become more and more casual.
"Did you buy it at You Shuiping's store?"
"How dare I go to someone else's house to buy it if you tell me to do so?"
"How much did you buy?"
"Fifty thousand yuan!"
"Yeah! It's okay."
Wan Feng nodded and hung up the phone, then checked the time.
It's three o'clock.
Go home first, because you have to come back to set off fireworks in the evening. As for watching the concerts of those singers, Wan Feng doesn't plan to go, there's nothing to see.
Luan Feng and Zhang Xuan just need to take their parents and children to take a look.
Wan Feng told the people in the workshop that they should go home early today as it is National Day and there is plenty of time to work.
Then drove home.
There are national flags of all sizes hanging on the doors of every household in Wankou, and the entire long street in Wankou is a sea of red.
A two-foot square national flag was also hung above the door of the Holi Communications store, fluttering in the wind.
It has been twenty days since the couple opened their shop, and Wan Feng has never been here except for the opening ceremony.
He didn't plan to go over and ask today. The grudge between the two sides had been settled, and there wouldn't be many opportunities for them to meet in the future. Let them live their lives in peace.
Wanfeng turned onto Wankou Street and headed west, then turned at Shanwan intersection and headed home.
When the car reached the fork in the road leading to his home, Wan Feng saw several cars parked in front of You Shuiping's store. He also unexpectedly saw Wang Chunjiang.
This guy is putting firecrackers on the light of his happiness.
