I am used to driving electric cars. What are the gaps after switching back to fuel vehicles?
People who are used to driving electric vehicles will feel uncomfortable after switching back to fuel vehicles, especially without a quiet driving environment and a refreshing sense of speeding up.

Just like: people who used to be in an office, no one can argue with themselves; Now I have changed my job as a bar security guard. I feel deafening and uncomfortable every day.

The difference in driving experience accelerates the difference in somatosensory perception. 1 The most obvious difference is that the vehicle speed has slowed down, especially at the starting and middle and low speed. Of course, what we are talking about here is a general family car, not a super-running and performance car.

There is a paper "Torque Distribution Control of Electric Four-wheel Drive Hybrid Vehicle" in Automotive Engineer magazine.

Because the electric vehicle is driven by the motor, it can output 100% torque when it starts automatically, which is impossible for the traditional internal combustion engine.

Tell people the truth: torque is equivalent to how much force you have to use to turn the wheel. Whether it's "er" or "ha", the difference is so big.

For electric vehicles, starting directly means sprinting with all one's strength, and fuel vehicles need to run and brew. Therefore, low-speed acceleration of electric vehicles is better than that of fuel vehicles.

People who are used to electric vehicles switch back to fuel vehicles and feel, "Oh, my God, the acceleration is not good."

Driving habits are not suitable. In addition to acceleration, the second gap in driving experience is: braking time.

General electric vehicles have kinetic energy recovery systems. There is a paper in the magazine System Simulation Technology, which is about regenerative braking of electric vehicles based on comfort.

The motor of pure electric vehicle can produce braking force, which can convert the wasted kinetic energy into electric energy and store it, and also change the braking feeling and comfort of the vehicle.

Talking to people: fuel trucks can almost wade through without stepping on the accelerator and braking, and they are taxiing, right?

Because of the kinetic energy recovery mechanism, when the electric car doesn't step on the accelerator, the motor runs in the opposite direction, giving the impression that it is dragging the car to slow down.

When you get used to this kind of driving and switch back to a fuel car, the timing of braking will be a little different.

For example, as soon as I let go of the accelerator, I slipped at the traffic lights and basically stopped.

But switching back to a fuel car is slippery and slippery. "Alas," I have to repair the brakes, and I can't get used to it at once.

After talking about the driving experience, let's talk about the riding experience.

Generally speaking, the electric car has no gearbox, but is directly driven by the motor, so there will be no problem of gear shifting frustration.

There are no gears, so there are no gear changes, right? As smooth as oil on the soles of your feet. After switching back to a fuel car, there is basically no such experience.

Moreover, after switching back to a fuel car, you may not experience a quiet driving environment, or just an engine and motor, right?

The motor doesn't have any air intake and exhaust system, so it turns over there, right? Of course, the "boom" sound of the original engine is gone.

And the vibration and noise of the whole vehicle will be reduced accordingly. There is a paper in Automotive Engineering magazine, which talks about "the improvement of the interior noise and sound quality of an electric vehicle".

The vibration and noise of electric vehicles are 3 to 6 decibels lower than those of the same traditional fuel vehicles.

Have no idea? In terms of noise suppression, reducing 6 decibels is equivalent to half of the original volume, okay?

Therefore, after switching back to a fuel car, the sound of the engine, the sound of intake and exhaust, and the vibration will reduce our ride experience, unless you especially like to listen to the roar of the engine.

The difference in economic cost is used to charging the car every day. After switching back to a fuel car, you will feel bad about your wallet every time you refuel, which is also one of the gaps.

Compare the gasoline version and the pure electric version of Geely Emgrand. Are these cars the same? The fuel consumption of gasoline version is about 8L, 1 km, 43 cents.

Power consumption per 100 kilometers of pure electric version 13kWh. If the electric pile uses civil electricity, 1 km is almost 1 dime, right?

If it is replaced by refueling, it will be calculated according to the price of Hangzhou No.92 gasoline. If you fill up a tank of 50L gasoline, it means that every time everyone fills it up, you have to pay 27 1 yuan.

Moreover, the electricity fee for electric vehicles is cheap, and it is paid together with the electricity fee for home use every month. There is not much feeling that there is such an action of paying back money, and it is not easy to feel distressed when it is automatically buckled together.

On the contrary, every time I refuel, the money is three or four hundred, one by one, or scanned. There is such a process, but it will be more painful.

The gap in travel convenience Finally, for cities with limited numbers, it is necessary to worry about traveling in exchange for fuel vehicles.

Hangzhou, where I live: Hangzhou license plate will be restricted by the wrong peak on weekdays. New energy license plates and green license plates can drive freely without this restriction.

The biggest impact is the driving experience and static gap, so in a word: friends who are used to driving electric cars do have these gaps objectively after switching back to fuel cars.

For most friends, the biggest impact is the difference between driving experience and mute.
