3：经常开车的朋友都知道堵车或者低速行驶时汽车最耗油，根本原因是 发动

3: Friends who often drive know that the car consumes the most fuel in traffic jams or at low speeds. The fundamental reason is that the engine does not reach the optimal operating conditions, gasoline is not fully burned, resulting in low fuel efficiency, and the engine in the extended-range hybrid is not controlled. The wheel drive is not limited by the speed of the car and can always be at the optimal speed, so whether it is fuel economy or nvh has improved. <br><br>Disadvantages: <br><br>1: The overall structure is more complicated, and the cost is much higher than the plug-in hybrid model, resulting in no advantage in selling price. <br><br>2: In the case of running at high speeds, extended-range vehicles are not necessarily more fuel-efficient than ordinary fuel vehicles. The reason is that on the one hand, the fuel engine can be in a very suitable speed range on high-speed road conditions, and it obtains good economy. On the other hand, because there is no transmission in the pure electric car, the energy consumption performance is definitely not as good as that of the traditional fuel car. <br><br>3: Because the engine and generator do not directly drive the wheels, the vehicle can only exert the power of the electric motor, which causes a part of the waste of power. <br><br>Applicable people: Charging is not convenient, the car scene is more on urban roads. <br><br>04 Parallel hybrid

3: Often driving friends know that traffic jams or low-speed driving when the car most fuel consumption, the root cause is that the engine did not reach the best operating conditions, gasoline combustion is not enough, resulting in low fuel efficiency, and the engine in the addition of mixing does not control the wheel drive, not limited by the speed of the car, can always be at the best speed, so whether it is fuel economy or vhnvh have improved.<br><br>Disadvantages:<br><br>1: The overall structure is more complex, the cost is much higher than the plug-in hybrid model, resulting in no advantage in the price.<br><br>2: High-speed running situation, the addition of the car is not necessarily more fuel-efficient than ordinary fuel car. The reason is partly because the fuel engine can be in a very suitable speed range in high-speed road conditions, get good economy, on the other hand, because pure electric vehicles do not have transmission, energy consumption performance is certainly not as good as conventional fuel vehicles.<br><br>3: Because the engine and generator do not directly drive the wheels, so the vehicle can only play out the power of the motor, resulting in a part of the power waste.<br><br>Suitable for the crowd: charging is not convenient, car scene is more in the city road.<br><br>04 Parallel Mix

3: Friends who often drive know that cars use the most fuel when they are stuck in traffic or driving at a low speed. The root cause is The engine does not reach the best working condition, and the gasoline combustion is not sufficient, resulting in low fuel efficiency. However, the engine in the increased program hybrid does not control the wheel drive, is not limited by the speed of the car, and can always be in the best speed. Therefore, both the fuel economy and NVH have been improved.<br>Disadvantages:<br>1: The overall structure is relatively complex, and the cost is much higher than that of plug-in hybrid models, resulting in no advantage in the price.<br>2: In the case of high-speed running, the fuel consumption of an incremental vehicle is not necessarily lower than that of an ordinary fuel vehicle. On the one hand, the fuel engine can be in a very suitable speed range in high-speed road conditions, and get good economy. On the other hand, the pure electric vehicle does not have a transmission, so its energy consumption performance is certainly not as good as the traditional fuel vehicle.<br>3: Because the engine and generator do not directly drive the wheels, the vehicle can only play the power of the motor, resulting in a part of power waste.<br>Applicable crowd: it's not convenient to charge, and the driving scenes are more on urban roads.<br>04 parallel hybrid<br>
