Plug-in hybrid vehicle advantages are obvious but still have 4 major shortcomings, destined to be "transitional products", but also a sum of accounts, found that "fuel saving is really saving money is false", advise people who want to buy new energy vehicles to think twice, do not just look at the advantages, in fact, the shortcomings are the key to choosing a car, I use personal experience to tell you the real situation.
Originally wanted to start a pure electric car, but considering that occasionally will run a long distance, pure electric vehicle endurance anxiety has always existed, so I chose the Tang DM plug-in hybrid model, at first I did think that its advantages were obvious, but with the use of the car for a long time, many car scenes exposed its shortcomings, shortcomings are hard injuries.
Hard wound one, fuel saving does not save money
General plug-in hybrid models are given priority to the use of motor drive by default, when the battery power is not enough to provide driving force when the system switches to fuel mode, BYD Tang DM pure electric mode, 100 kilometers of power consumption is about 18 degrees, in the state of power loss, the engine fuel consumption is about 12L.
Mainly to the city car-based, high-speed as a supplement, the average electricity consumption + fuel consumption is about 10 degrees + 5L, the home installed charging pile, the average 1 degree of electricity is about 5 mao, if you go to the outside public charging pile, it probably takes 1.5 yuan a kilowatt hour of electricity, on the whole, the average 1 degree of electricity is about 8 mao.
By default, add No. 92 gasoline, to the current oil price of 8.5 yuan / L to calculate, the total cost of 100 kilometers of oil and electricity is about 50 yuan, the same is a 2.0T engine, the comprehensive fuel consumption of Volkswagen Passat is about 9L, and the fuel cost of 100 kilometers is about 77 yuan.
Compared with fuel vehicles, plug-in hybrids save about 1/3 of the fuel money, if it is a daily commute, most of them are within a radius of 50 kilometers around the city, then most of the cases are using pure electric mode, in this case, sometimes filling a tank of oil can run more than a thousand kilometers.
Assuming that 15,000 kilometers are driven a year, then about 4,000 yuan can be saved a year, and there is no doubt about fuel saving, but only from the perspective of economic cost, the comprehensive cost of hybrid models is very high.
The new car premium is higher, the same model, are low-end versions, BYD Tang fuel vehicle landed about 160,000, and Tang DM plug-in hybrid model low-end version priced up to 240,000, equivalent to nearly 80,000 more expensive than fuel vehicles, of course, Tang DM is a four-wheel drive model, but even if these are reduced, it is still at least 50,000 more expensive than fuel vehicles.
Look at other same fuel vehicles and plug-in hybrid models in the industry, such as the Passat fuel version landing price of about 190,000, the same plug-in hybrid model landing price of nearly 230,000, in short, plug-in hybrid models due to more than a set of drive systems, the cost is slightly higher, the premium is higher.
Hard injury two, second-hand retention rate is low
Plug-in hybrid models of used cars retention rate is generally low, on the one hand, hybrid models are the new models in recent years, some people are worried that its technology is not mature enough, on the other hand, worry about battery life problems, after all, the cost of replacing batteries is very high. In addition, there is no perfect second-hand car evaluation standard on the market, in short, a variety of factors have led to a low retention rate of second-hand cars.
Taking bydie Tang this model as an example, the 2019 low-end version of the fuel car travels 50,000 kilometers in 3 years, the second-hand car is about 120,000, the second-hand retention rate is about 70% off, and the same Tang DM, almost the same car condition, the second-hand car is about 140,000, equivalent to the second-hand retention rate of about 5.5% discount.
That is to say, 3 years of age, hybrid vehicles than fuel vehicles thanks to at least 30,000 more, this is only within 3 years of the retention rate, 5 years after the hybrid car 5 discount may not be willing to take over.
Finally, the hybrid car needs two sets of power system at the same time, the structure, technology is more complex, according to common sense, the cost of later maintenance and repair is much higher than that of fuel vehicles, not only that, but the annual car insurance will be nearly 10% more expensive than the fuel car.
In short, assuming that the same 10 years of driving, a total of 150,000 kilometers, the hybrid model saves a total of about 40,000 fuel costs, and the fuel cost saved is not as much as the new car pays more, so it is said that the plug-in hybrid model saves fuel but does not save money.
Hard injury three, pure electric endurance is too short, need to be charged frequently
Plug-in hybrid models of pure electric mileage are very short, the previous years of the model general endurance are within 70 or 80 kilometers, these two years of individual models of pure electric endurance increased to more than 100 kilometers, to BYD Tang DM as an example, when the battery was only 20 kWh, the official endurance of 81 kilometers, but this is not the case.
If the temperature is low in winter, the heating and air conditioning run at high speed, the actual endurance basically needs to be about 40% off, that is to say, the actual endurance is only 50 or 60 kilometers, on average, the actual mileage is about 60 or 70 kilometers. In other words, if the mileage exceeds 50 kilometers, the battery is almost exhausted, and it becomes a fuel vehicle.
The day one-way driving more than 30 kilometers, after returning to need to charge, plug-in hybrid models are generally slow charging, it takes five or six hours to fully charge, charging at night, the next morning with the car, many owners want to save money, then only use pure electricity to drive, that is, must be charged frequently.
Hard injury four, power loss driving is not as good as fuel vehicles
Most plug-in hybrid models can only be driven when the fuel vehicle is used up if the battery is used up, and the plug-in hybrid model body is at least three or five hundred kilograms heavier than ordinary fuel vehicles, just like Tang DM, the body is generally more than 2.2 tons, using fuel mode, fuel consumption is higher, and many car owners lose power when the fuel consumption is as high as 13L or even more.
The body is heavier, the vehicle starting, acceleration, overtaking and other control performance will also be affected to a certain extent, Tang DM engine displacement is still relatively high, most of the plug-in hybrid models of the engine are within 1.6, which is equivalent to "small horse-drawn horse", really not like the level of fuel vehicles.
The above mainly said some shortcomings of plug-in hybrid models, but its advantages are also very obvious, which is why many car companies are now launching different versions of plug-in hybrid models, like BYD's latest DM-i technology, it can be said that it combines the advantages of plug-in and oil-electric hybrid models.
Spend 200,000 to buy a hybrid model to enjoy the power performance of 500,000 fuel vehicles
The power performance of the hybrid is impeccable, taking the new BYD Han DM-i and BMW 525 as an example, and the gap between the latter two is too obvious.
The BMW 525 is powered by a 2.0T turbocharged engine with an engine power of 135 kW, a maximum horsepower of 184 hp, a maximum torque of 290 N·m, and zero hundred acceleration of 8.6 seconds.
The BYD Han DM-i motor has a power of 145 kW, a maximum torque of 316 N·m, and an acceleration of 7.9 seconds per 100 km/h. The continuous linear output of electric drive power can provide greater torque in the same time, and even if the thermal efficiency of the fuel vehicle engine is improved by 0.5%, it is more difficult. Many car owners are deeply attracted by its power performance after test driving new energy models, which is the essential difference between motor drive and fuel engine drive.
NVH comfort, sense of technology, assisted driving, green card and other advantages
Plug-in hybrid models, pure electric vehicle type motor drive, no engine jitter, body design is also conducive to reducing wind resistance, in addition to the rapid acceleration of a slight hum sound, in addition to the whole process is very quiet, which is far from the fuel car.
Living in the first- and second-tier cities with limited licenses and limited numbers, it is easy to buy a car and it is difficult to get on the license, many people have not been selected for several years, and even some places have a "blue card" comprehensive cost of nearly 100,000, while pure electric vehicle models and plug-in hybrid models enjoy the "green card", directly saving all troubles.
Another advantage of new energy models is that auxiliary driving, the intelligent system of the car machine is very powerful, automatic parking, fixed speed and other scenarios can achieve "free hands, feet", which is of great help to many novices, which are the advantages that fuel vehicles cannot catch up.
In short, at this stage, the advantages and disadvantages of new energy vehicles coexist, all depending on the personal car scene, if it is because of the power performance, sense of science and technology, auxiliary driving and other advantages of new energy models, then buying a car must not regret, of course, you also need to pay attention to, there must be a household charging pile, otherwise it is a very troublesome thing to often go outside to charge.
If you choose new energy vehicles in order to save money, then I sincerely advise you to think twice, whether it is plug-in hybrid, pure electric vehicles, oil-electric hybrid, hydrogen energy models are "fuel saving but not saving money".
