There will be first-order vibration and second-order vibration when the internal combustion engine is running. Most manufacturers will use a balance shaft or a balance weight to balance the force in the first-order vibration, while the second-order vibration is not so easy, and most of them are buffered by the rubber of the engine foot. After a long time, the rubber of the engine foot will age, and the vibration will spread to the interior of the carriage, which will affect the driving quality.

In addition, the internal combustion engine needs a gearbox to slow down. The deceleration here is not in the traditional sense, but the power output by the engine changes through the transmission ratio of the gearbox to achieve the speed and torque required by the vehicle. The existence of the gearbox means that the vehicle will shift gears, and there will be setbacks and jerks when shifting gears, especially the dual-clutch gearbox, which is prone to setbacks when following the car at low speed, further affecting the driving experience.

But! Electric cars won't have this problem. The electric vehicle only has a simple three-electric system-battery, motor, electronic control, plus a main reducer, which constitutes the main drive system of the electric vehicle. The motor runs smoothly, there is no vibration problem, and the noise problem will be smaller than that of the internal combustion engine. More importantly, most electric vehicles will not have gears, so there will be no shift problem, so the driving quality will be greatly improved, and the output of the motor mainly depends on electronic control, which can accurately adjust the motor.

Under normal circumstances, the internal combustion engine needs to be started, the compressor works and the air conditioner produces cold air. But heating is not so easy. Under normal circumstances, the heat source of internal combustion engine is the heat of engine, so if you want to heat air, you must wait for the engine to have enough heat before you can supply warm air to the carriage, and the process from cold engine to hot engine often takes about 5 minutes.

Electric cars are different. At present, there are two kinds of heating for electric vehicles, PTC and heat pump. PTC heating is similar to the air duct we use, which is heated by heating wires and then transferred to the interior of the carriage by fans. The advantage of this is that it is fast, and hot air will be generated in almost a few seconds after it is turned on, and there will be no embarrassing situation that the fuel car needs to wait for a few minutes. A heat pump is similar to an air conditioner, except that the outdoor heat is transferred to the car. Although this heating speed is not as fast as PTC, it has little effect on endurance, that is, it saves electricity. Endurance is the life of an electric car, saving a little.

It must be said that the driving assistance function of electric vehicles is more perfect and intelligent than that of fuel vehicles. The selling point of electric vehicles is intelligence and technology. Basically, as long as it is not particularly bad electric vehicles, it will be equipped with relatively excellent driving assistance systems, especially new power manufacturers, such as adaptive cruise, lane departure assistance, active braking and so on. The author who has just experienced holiday congestion deeply feels the convenience brought by the driver assistance system. If there is a driver assistance system, you can start the "leisure mode" when there is traffic jam to let the vehicle follow the car automatically, and then control the vehicle after leaving the congested road section. This will greatly reduce the fatigue of drivers, and there is no need to pay attention to traffic congestion at all times.
