"oh!"

When the Origin car jumped out like a cheetah, it caused a burst of exclamations from the scene!

The powerful torque of the two permanent magnet synchronous motors is much more powerful than the engine of an ordinary fuel vehicle!

The engines of ordinary fuel vehicles do not work directly on the wheels, but are transmitted through the gearbox, so that the engine torque gradually increases!

The electric motor directly bursts out the maximum torque!

So you can often see that the starting speed of a car is not even as fast as an electric car...

Just like the Tesla that everyone is familiar with in electric cars, the Tesla worth 300,000 can accelerate from 0 to 100 kilometers in 2.8 seconds! It directly kills many fuel sports cars with a speed of 300 kilometers!

Li Cheng, who was in the cab, was also surprised by the powerful ability of the Origin Car. The strong pushing force fixed Li Cheng in the driver's seat!

Accompanied by the unique engine sound of the electric motor, the Origin car sped along the straight runway!

"brake!"

With strong self-control, Li Cheng stepped on the brakes after hearing the command from the commander!

An inexplicable feeling of emptiness comes, which is why many drivers are prone to accidents when driving fast.

The adrenaline secretion caused by high speed makes people want to stop and just want to keep stepping on the accelerator pedal without letting go!

"Zhi~zhi~"

The screeching sound of tire friction sounds intermittently. This is when the car's ABS system starts to work.

Under everyone's gaze, the Origin car stopped steadily not far from the brakes!

Director Tang, who was recording the data, looked like he had seen a ghost!

Because the data shows that this car only took twelve meters from braking to stopping!

At a speed of 80 miles, the braking distance of an ordinary car is about 25 to 28 meters! But the Origin car only has less than half the distance of other cars!

"How is this possible?" The deputy also saw this data and was equally unbelievable!

Director Tang, on the other hand, habitually adjusted the frame of his glasses, fearing that he would read the wrong data, which would be a big loss!

"The data is correct! It's not easy to brake this car!" Director Tang looked obviously happy!

Director Tang may not be good at driving vehicles, but when it comes to vehicle performance, he is definitely an expert!

Normally, vehicle braking works on two resistances, one is the friction between the brake and the brake disc, and the other is the friction between the tire and the ground.

In the case of sudden braking, if the friction force of the latter is greater than the former, it will stop directly there.

However, if the former is greater than the latter, it will lock and slide!

Just like a person running fast and suddenly stopping, if the speed is not fast and the inertia is not big, he will stop. But if the speed is too fast, it is best to stop in small steps, otherwise he will either fly out or fall into a big mess!

Seeing this situation, Xu Feng, who had been worried about it, felt a little relieved. After all, the factory test and the tester test are still different, but now it seems that the effect is very good!

This is actually due to the on-board intelligent control system.

Generally, cars are divided into front-wheel drive, rear-wheel drive and four-wheel drive systems. The lock-up control performance of the front-wheel drive is reduced, and the rear-wheel drive is prone to drifting due to lock-up, while the braking performance of the four-wheel drive is the best!

The Origin car uses a four-wheel drive system.

Moreover, ABS actually controls the pressure on the wheel brakes to prevent the car from locking the wheels.

The braking systems of the four tires of the Origin car are all controlled by intelligent systems!

The frictional resistance of all tires and the kinetic energy of the entire vehicle are accurately calculated by the system, and the control intensity and interval are quickly calculated with microsecond-level processing capabilities.

In the shortest time and distance, let the car stop without losing control!

"It's absolutely amazing, believe you me." Foreign reporters who were taking pictures also exclaimed in disbelief when they saw the data.

There is nothing fake about this, it is all a public test, the situation is an ordinary asphalt road, and everyone has their own considerations about distance and time, so I can’t believe it even more!

"The elk test will begin next!" Director Tang, who had had a straight face since before the test, now looked much softer!

After the car performance reference was sent from Origin Company, Director Tang's impression of Origin Company actually plummeted.

In Director Tang’s opinion, a lot of data is just blown out! If others knew about it, they would definitely laugh out loud!

Moreover, it has not been tested at all. It was sent for testing right after it came off the production line, and it was also a public test!

Isn't this just adding salt to the wounds of China's automobile manufacturing industry, which is already suffering from difficulties, and making it worse?

However, looking at the current situation, there may really be two reasons for the origin!

The next so-called elk test is not to imitate the elk driving. To be more vivid and specific, it should be called the elk avoidance driving test.

The "elk test" is an important international standard for measuring vehicle safety. You can understand it as an emergency line change and then change back to avoid obstacles and ensure safety.

In the past, in Northern Europe, vehicles there were often in danger of avoiding elk that suddenly appeared on icy and snowy roads.

Therefore, in this test, people imitated this extreme situation, simulating the driver's high-speed avoidance situation in the test track, setting up stakes according to standards, and changing lanes at a certain speed.

Therefore, the "elk test" is to test the vehicle's ability to avoid obstacles. It can be a test on the entire chassis system such as the car's steering, suspension system, and tires.

Under normal circumstances, the Elk test result can be said to be good when it is 70-79km/h, and it is already excellent if it exceeds 80km/h.

This experiment cannot be carried out by one person, this time it was carried out by four test drivers!

Moreover, the trunk is also filled with counterweights to simulate testing the car's performance under full load!

The driver needs to enter the test area at a constant speed and dodge around piles at high speed without stepping on the brake or accelerator.

Then the two testers in the front two seats repeated the process, gradually increasing the vehicle speed, recording the vehicle speed at that time when the out-of-control condition was reached, and conducting two more verifications to determine the reliability of the out-of-control vehicle speed value.

The first test was set at a speed of 60 kilometers per hour!

When the speedometer of the car reaches 60, it turns on the cruising speed and starts the S-row around the pile at a speed of 60 kilometers per hour.

There was almost no sign of instability in the vehicle, and no one was too surprised.

Looking at all the Elk test results, most of them come from expensive sports car models. After all, they have a low center of gravity and strong road grip, which is understandable.

However, when the speed of the car reached 80 kilometers per hour, not only Xu Feng, but also Director Tang and the surrounding audience began to become nervous!

At the beginning, Citroën Xantia Activa V6 occupied the top spot with a speed of 85km/h. This was the data in 1999!
