What are the advantages and disadvantages of traditional cars?

Hybrid power generally refers to oil-electric hybrid power, that is, the combination of fuel drive and electric energy drive; Hybrid electric vehicle (HEV) is a vehicle driven by the simultaneous operation of fuel engine and battery motor. Traditional cars use gasoline and diesel as fuel.

Compared with traditional fuel vehicles, hybrid vehicles have high fuel economy and superior driving performance. The engine of the hybrid electric vehicle uses fuel, but when starting and accelerating, with the help of the motor, the fuel consumption can be reduced, and the internal combustion engine can be turned off, and the "zero" emission can be realized only by battery driving, which is of great significance to the increasingly severe environmental protection and oil resource conservation. In addition, in addition to the related advantages in economy and power, hybrid vehicles perform better in reducing the mechanical noise inside the car.

Of course, due to the late development of its technology, compared with traditional cars, many aspects are not fully mature, so its related products are overpriced, and the cost of two power systems of electric motor and internal combustion engine is much higher than that of one power system. Moreover, when driving at high speed or at a constant speed for a long time, its fuel economy is not excellent. Because the advantage of fuel consumption of hybrid electric vehicles mainly depends on potential energy to save energy, the more frequent braking deceleration of hybrid electric vehicles, or frequent start and stop, the more energy is saved, and if they drive at a constant speed for a long time, their energy-saving effect will be correspondingly reduced. In other words, congested urban streets are more suitable for hybrid vehicles.
