The highway with no speed limit is about to open? Don’t rush! It’s fun and safe to do so!

If you want to talk about the most popular news related to car owners recently, it is probably that "the country's first unrestricted expressway is about to open " news.

This news has caused a very extensive and heated discussion. Car fans are excited about the emergence of unlimited speed highways. Some car owners expressed doubts and even worries about it: Where do highways with no speed limits come from? Why build a highway with no speed limit? What is it like to drive on such a road? What should I pay special attention to when driving?

In response to these issues, the professor will briefly chat with you today.

First of all, let’s talk about the first question: Where do highways without speed limits come from? Why build a highway with no speed limit?

In fact, the concept of unrestricted highways originated from the German Autobahn, which is Germany's "Federal Autobahn". In Germany's highway network, except for about 23.4% to 29.6% of the speed-limited sections (some sections may have temporary speed restrictions), most of the remaining highway sections do not have a maximum speed limit (the picture below shows the German Autobahn sign ).

The Hangzhou-Ningbo Expressway, which is about to be completed and put into use, is an unrestricted expressway designed based on the German unrestricted Autobahn. .

It is understood that this 161km-long Hangzhou-Ningbo Expressway connects Hangzhou and Ningbo; due to the significant increase in driving speed, The efficiency of vehicle commuting between Hangzhou and Shaoxing and Ningbo is expected to be greatly improved.

The current journey from Hangzhou to Ningbo takes up to 2 hours. If the Hangzhou-Ningbo Expressway with no speed limit is opened in the future, the two cities will The commuting time will be greatly reduced. As long as the vehicle performance is strong enough, it may only take an hour to complete this journey.

It can be seen that improving travel efficiency is the most important reason for building highways without speed limits.

However, the question we want to talk about next is very critical: what is it like to drive on an unrestricted highway? Experience? What exactly do you need to pay attention to before and during driving?

In this regard, the professor believes that we should talk about the experience first.

The professor has not tried driving on Germany’s unrestricted autobahns, but has done many track drives and automotive majors I have experience in the high-loop road section of the test site, so I still have a little understanding of the driving experience of the vehicle at ultra-high speed.

First of all, when the vehicle is traveling at ultra-high speeds exceeding 120km/h, or even exceeding 200km/h, the driving conditions of the vehicle The feeling will be quite different from the state within 120km/h.

For example, the noise inside the car will increase significantly, whether it is wind noise or tire noise, which will have a significant impact on ride comfort. .

While driving at ultra-high speeds, the vehicle's aerodynamic design and chassis tuning level will be revealed in a more perceptible way. ; For example, models with excellent aerodynamic design can feel better driving stability when driving at super high speeds, giving people more confidence.

However, models with slightly insufficient aerodynamic design will cause the vehicle to appear "" when driving at ultra-high speed due to the influence of turbulence. erratic” phenomenon.

So as long as the speed is high enough, the true performance and design level of your car can be fully demonstrated, and you can even use this Performance determines whether you should change cars.

In addition, as the speed increases, the vehicle's response to steering, braking and other operations will become more sensitive. You need to be more focused and careful when driving, and be careful not to swerve suddenly to avoid losing control of the vehicle while driving at super high speeds.

The content we want to talk about next is directly related to the key issue of travel safety.

In terms of road design itself, the Hangzhou-Ningbo Expressway referred to the German Autobahn design standards during construction. It is reported that the construction cost per kilometer is as high as 400 million yuan, the need for ultra-high-speed driving has been taken into consideration from the initial stage of road paving.

However, the driving behavior of the car and the driver itself will become a safety hazard on the highway.

Therefore, in order to enjoy the efficiency and convenience of ultra-high-speed driving more safely, there are some details that you must pay attention to before using the Hangzhou-Ningbo Expressway in the future. of.

First of all, the car can certainly cope with high-speed cruising conditions within the designed maximum speed range when it is new, but as time goes by, Auto parts will age, and since each user's maintenance and driving habits are different, the actual vehicle condition will also vary.

Cruising for a long time at ultra-high speed is a big challenge for the vehicle's power system, especially the engine. Maintaining high-speed operation for a long time will cause relatively high working pressure.

Even if it is a vehicle that is used normally on weekdays, in a higher speed and higher temperature environment during ultra-high-speed cruising, some Hidden security risks may arise.

Therefore, before driving a vehicle onto an unrestricted highway, you must check the working status of the engine and the consumption of engine oil, coolant, etc. The condition of the product.

In addition, special attention should be paid to the condition of the tires, not only to ensure that the wear level of the tires is within a reasonable range, but also to pay attention to the tires Whether it meets the corresponding speed requirements.

The last digit of the size parameter mark on the side of the tire is usually an English letter, and this English letter corresponds to this The maximum driving speed standard supported by this tire.

For example, P-class tires support a maximum speed of 150km/h, S-class tires support a maximum speed of 180km/h, and V-class tires support a maximum speed of 150km/h. 240km/h etc.

If the tire speed rating is low, then you should not try to exceed the speed limit of the tire.

Finally, everyone needs to pay special attention to their driving habits.

Although "nine times out of ten accidents happen quickly", speeding is considered a dangerous driving behavior and most users are In the process, the driving speed is often deliberately reduced to "ensure safety" or to avoid violating traffic regulations; however, on an unrestricted highway, the danger of driving below the speed limit will be greatly magnified.

Since the speed limit of the vehicle is cancelled, this will cause the speed difference between the slow train and the fast train to be further amplified; once the two vehicles If a collision occurs, the severity of the accident will be higher.

Therefore, when driving on an expressway with no speed limit, everyone must remember: as long as the road conditions permit, you must maintain a sufficient driving speed. It is best not to drive at a speed lower than 120km/h.

Also, never occupy the left fast lane and drive back to the right lane as soon as possible after overtaking; while driving , everyone should pay more attention to the surrounding traffic conditions than usual; if you observe a vehicle approaching quickly from behind, you should give way in time to avoid a rear-end collision; during the lane change process, you should also observe the road conditions on the side and rear of the vehicle more carefully to ensure safety.

Finally, for new energy vehicles, unrestricted highways will definitely bring them huge challenges.

For most new energy vehicles currently on the market, 80-100km/h is their relatively economical cruising speed. If you drive at a speed of 100-120km/h, energy consumption will increase to a certain extent.

When the speed exceeds 120km/h and continues to climb, the motor needs to run at full power to provide power for the vehicle. The air resistance encountered will also be greater, energy consumption will increase significantly, and the endurance will naturally be reduced.

Therefore, for new energy vehicle users, they still need to confirm the battery life of their car before using an unrestricted highway. Range is adequate, and charging schedules are set up in a more conservative manner.

As long as the vehicle condition is normal and the rules are followed and driving is safe, the Hangzhou-Ningbo Expressway, an expressway with no speed limit, will indeed become a popular choice for commuters in Zhejiang Province. The most efficient road.

However, the professor still has some worries about canceling the speed limit.

For example, for most drivers, driving a vehicle at a speed exceeding 120km/h is a "scary" thing This incident is completely contrary to the driving philosophy of "lowering speed to ensure safety" that we have always accepted.

Unlimited highways are a very new thing for most domestic drivers and have never been exposed to. Although it sounds very exciting, after all, everyone has never tried driving at such a high speed for a long time. You should be more cautious in the early stage and slowly adapt to the new driving experience.

Oh, by the way, there is one detail that needs to be mentioned: after the opening of the Hangzhou-Ningbo Expressway, the speed limit will not be lifted immediately; A speed limit standard of 150km/h will be set; if the high-speed operation is smooth and safe, this speed limit will be lifted in the future.

Compared with enjoying the convenience and pleasure of driving without speed limits, arriving at the destination safely is always the most basic and important thing need. Therefore, everyone must focus more on driving and abide by the rules, so that they can make good use of the unrestricted highway and expand this new thing to more highway sections so that everyone can enjoy an efficient travel experience.
