Domestic Tesla Model 3 started for more than a year, summed up the 6-point car experience, the heart of the mixed feelings, regret when the original choice of Tesla, and did not choose Xiaopeng or BYD. Although Tesla's 3-point advantage is obvious, the 3 major shortcomings are the pain points, each one poking the heart. I hope that those who want to buy pure electric vehicles should think twice, buy a car to understand its advantages and disadvantages and their actual car conditions, otherwise regret it!
In the current pure electric vehicle market, if you want to spend about 300,000 yuan to buy a pure electric vehicle, then you can't avoid Tesla Model 3, BYD Han EV and Xiaopeng P7. These three models have a fight in terms of appearance, endurance, performance, etc., and the price of some of their models is almost the same.
I first went to test drive the Xiaopeng P7 and BYD Han EV, finally test drove the Tesla Model 3, and finally decided to start the Tesla Model 3. There are three main reasons why by not choosing the BYD Han EV and Xiaopeng P7:
1. In terms of brand influence, Tesla is more influential than Xiaopeng and BYD. It is undeniable that Chinese people pay more attention to the "face" factor when buying cars, and I am no exception. Tesla is like the BBA in the traditional fuel car companies, driving out will always have a little more face.
2. In terms of assisted driving, Tesla beat BYD. The assisted driving of BYD Han EV has no problem using full-speed adaptive cruise on relatively straight roads, but when encountering relatively large curves and undulating road surfaces, it cannot be recognized and requires manual intervention. The automatic driving of by THE BYDHAN EV is led by ICC intelligence, coupled with ACC lane keeping, combined into L2 level automatic driving, to be honest, it can only be regarded as L1.5 level. In contrast, Tesla's Autopilot and Xiaopeng P7's X-Pilot3.0 autopilot technology, whether in the city congestion road conditions, or under the high-speed car, can achieve a good transition and distance maintenance, such as the rush hour of commuting to meet the traffic jam, open the auxiliary driving function, adjust the driving distance, and then you can free your hands to brush the mobile phone.
3. I live in Nanjing, Nanjing winter temperature is still relatively low, the coldest time will be below zero, considering that BYDHan EV is equipped with lithium iron phosphate blade battery, in the winter cold environment the endurance decline is more exaggerated, and Tesla Model 3 is equipped with a ternary lithium battery, affected by the low temperature environment is smaller, more suitable for the winter cold environment.
In fact, these are small problems, mainly because the business ability of Tesla's 4S store sales is too strong, and the Tesla three-electric system and the Autopilot autopilot system are too good, so that I originally had a budget of 250,000 yuan, and finally borrowed tens of thousands of dollars, spent an additional 64,000 yuan, and installed the Autopilot fully autonomous driving function. A momentary impulse led me to regret it later.
Tesla Model 3
Feeling one: pure electric vehicle power performance is also "chicken ribs", high speed, air conditioning, low temperature environment are all problems it can not avoid
The new car has been open for more than a month, and in the process of using the car, various problems have slowly emerged, and then I understand that the advantages I thought before were actually of little use, but became a "chicken rib". For example, the power performance, compared to the BYD Han EV and Xiaopeng P7, is also a single motor mode, and the Tesla Model 3 has the strongest performance.
Tesla Model 3: Maximum power 202kW, maximum torque 404N·m, zero hundred acceleration 5.3 seconds.
BYD Han EV: Maximum power 163 kW, maximum torque 330 N·m, zero hundred acceleration 7.9 seconds.
Xiaopeng P7: Maximum power 196kW, maximum torque 390N·m, zero hundred acceleration 6.7 seconds.
In terms of power performance, Tesla can be said to be a ride on the dust, but to be honest, daily urban transportation, this power performance is not used at all, even if zero hundred acceleration 3 seconds can be, it is not still stuck on the road. This kind of dynamic performance can only be exerted under special conditions such as track and high speed.
But we know that electric vehicles running high-speed is a nightmare, driving back to their hometown during the New Year, a high-speed long-distance run down, the shortcomings of pure electric vehicles are vividly reflected, it can be said that high-speed, air conditioning and low temperature environment are pure electric vehicles can not solve the problem so far.
I actually planned my route before I traveled, and I could actually get home with just one charge on the way. But the opposite happened, just on the highway soon encountered traffic jams, at first it was fine, and then found that the battery power dropped a little fast, in order to save electricity, he had to turn off the air conditioner.
On a cold winter night, I drove to the first charging station, but found that I needed to queue for four hours to enter the station. After waiting in line for four hours, when it was finally my turn to charge, I found that the charging pile was faulty and could not charge. I had to re-queue another good charging pile, and tossed me back and forth for 6-7 hours, which really confirmed the sentence - "charging for an hour in line for half a day."
Later I learned that many other brands of pure electric vehicles, charging half an hour of electricity can almost reach 70% to 80%, and Tesla Model 3 charged for half an hour even 50% can not reach, queued for 4 hours, can only charge so little electricity, and embarrassed to occupy too much time, but there is no Tesla super charging pile on the highway, their own car charging on the shared charging pile is really not powerful.
It is because of this matter that I have never driven a pure electric car to run high speeds since then, especially on holidays, there will be more congestion, I choose to drive a traditional fuel car or take a high-speed rail to travel. This means that even if pure electric vehicles have excellent power performance, they can rarely come in handy. In fact, a pure electric vehicle power of 150kW is enough, no matter how much power is not useful, it is nothing more than a gimmick for car companies to increase sales.
Xiaopeng P7
Feeling two: They all say that electric cars are comfortable, but I dare not compliment them
Take my Tesla Model 3 for example, one of its sound insulation noise reduction is really not flattering, originally thought that pure electric vehicles in terms of noise must be better than the same level of fuel vehicles, because it does not have an intake grille, so the wind resistance coefficient of the whole vehicle is much lower than the same level of fuel vehicles, and because there is no engine, so there is no engine jitter and noise. reason
In terms of arguments, the NVH performance of pure electric vehicles is far superior to that of fuel vehicles of the same level, but in fact this is not the case. It feels fine when driving at low speeds, but once the speed exceeds 60km/h, the noise will be multiplied. Perhaps because the environment inside the car is too quiet, it causes the tire noise and wind noise outside the car to be particularly harsh, and the noise makes me irritable.
There is also Tesla's chassis tuning, really do not dare to compliment, chassis suspension is very hard, especially when crossing the pothole road, you can feel the obvious bumps, over a speed bump to make you upside down. I really can't understand that the car with a price of about 300,000 yuan, the chassis tuning is so poor, it is not as comfortable as more than 200,000 fuel vehicles, such as Maiteng, Accord, etc., the comfort is better than Tesla.
Perhaps Tesla has spent money on autopilot technology research, or Tesla's positioning is an electric coupe, and it does not put comfort first.
Feeling three: Tesla Model 3 interior space is too depressing
Among the three models of Tesla Model 3, BYD Han EV and Xiaopeng P7, the tesla Model 3 has the smallest size space. We can take a look at their actual data:
BYD Han EV: length, width and height of 4980*1910*1495mm, wheelbase of 2920mm;
Xiaopeng P7: length, width and height of 4880*1896*1450mm, wheelbase of 2998mm;
Tesla Model 3: Length, width and height of 4694 * 1850 * 1443mm, wheelbase of 2875mm.
BYD Han EV gives the first impression of being large, and indeed it is so, it is 4980mm long, almost 5 meters, wider than 1 meter 9, wheelbase more than 2 meters 9, if according to the fuel car, can be counted as a C-class car, certainly larger than the Model 3, and Xiaopeng P7 has a fight. Of course, due to the structure of electric vehicles and the volume of the battery, the car is large, the space is not necessarily large, and the actual space used in the car is relatively general.
This space gap is still relatively obvious, especially in height of more than 1 meter 8 I, dare to brake, a careless head will hit the front windshield, if the seat is adjusted a little, then the rear passengers are estimated to have knees to the front seat backrest, this ride comfort is indeed a little worse.
Feeling four: Although Tesla Model 3 uses a ternary lithium battery, in fact, in the cold environment of winter, the battery life has declined not many
The temperature in most of the northern parts of the mainland is basically below -10 ° C, which will greatly reduce its endurance for lithium-ion batteries. I have personally verified before that in the case of -10 ° C in the winter, tesla Model 3 can only run about 350 kilometers with full power, and it is also in the case of not turning on the heating, if the heating is turned on, it can not even run 300 kilometers.
In winter, the traditional fuel vehicle to open the air conditioner is actually not much fuel, because its heat comes from the engine water tank, through the blower in the car, the heat of the water tank is blown into the cab, which can also be said to be energy reuse. And electric vehicles are not the same, it has no engine, no heat source, it can only be generated by external heat pump equipment, powered by batteries, which is a bit like our home hair dryer, this power consumption is actually very large, will affect your judgment of mileage data, serious words may also be anchored on the road.
I also did a special test, in a low temperature environment, about -10 ° C, Tesla Model 3 overnight endurance will be reduced by about 30 kilometers.
According to my actual car use, the daily urban transportation 100 kilometers consumes about 13 degrees of electricity, while the high-speed driving 100 kilometers consume more than 16 degrees, that is to say, from my personal car situation, it is found that high-speed driving is nearly 3 degrees more than driving 100 kilometers in the city. This does not take into account the additional consumption of air conditioning, if the heating is turned on in winter, then the power consumption will increase sharply, I probably calculated that it is close to 3 kWh an hour.
Therefore, as far as the current battery technology is concerned, although the mileage has increased a lot, there are still problems with battery attenuation and motor power consumption characteristics. Daily city transportation is still very fragrant, if you want to run a long distance on the highway, or the city is in the cold north, then when buying a pure electric car, you still have to consider the actual use needs.
Feeling five: Although Tesla's Autopilot autopilot technology is relatively good, don't rely too much on it
Look at Tesla's proud selling point Autopilot technology, when test driving, because of the conditions, so did not fully experience all its functions, and then later in the actual use of the process, found that many situations it can not make a correct judgment, such as:
1. Once I was at the entrance of the high-speed ramp, there was a car cutting into my lane from in front of me, the car under autopilot control did not slow down, for safety reasons, I immediately took over the car;
2. In the city road, I hit the turn signal, but the car did not change lanes, in order to avoid affecting the driving of the car behind, I chose to take over the car;
3. Once on the highway, I turned on the car mode, after the front car changed lanes, there was no car in the front lane where I was, and then the car began to accelerate under the control of Autopilot, at this time, the right lane suddenly cut into a car, and my car did not immediately slow down, for safety reasons, I took over the car.
As can be seen from the above three times, there are cars in front of me cutting into my lanes and changing lanes is not successful, which is the main reason why I took over. The entry of the complication is likely to be that the rear of the vehicle in front of it has not fully entered the sensor's line of sight, so the vehicle cannot be identified in time. Autopilot's response to the vehicle in front of it was not very quick, but it did not rule out the possibility of close braking.
In addition to the functional realization level, I also asked a few questions about driving comfort:
1. Lane changes are not smooth enough. The steering wheel rotation amplitude when changing lanes is stiff, and the shaking is more obvious in the riding feeling, which is not as comfortable as cutting in at a small angle.
2. Decision-making is not crisp enough. During a lane change, the left lane change function was successfully activated, but after a hesitant pause on the left lane line, the abandonment action returned to the middle of the lane again. I speculate that the reason is that a Gold Cup on the left rear shows no signs of slowing down and is in sensor detection range.
Since I have used Tesla's assisted driving several times, I no longer dare to use the slightly more complicated road conditions, and I can only say that the more than 60,000 yuan spent is really a bit unjust. For their own safety, or do not rely too much on assisted driving, otherwise it is not only a problem of repairing the car, but also may "repair people".
Feeling six: On the cost performance, Tesla was crushed by BYD
1. Passive security configuration.
In terms of passive safety configuration, BYD Han EV can be said to crush Tesla Model 3, Han EV not only has more rear side airbags and knee airbags, but also holographic standard passive pedestrian protection system, which can be used in time to reduce the damage caused by collisions between vehicles and pedestrians, through active and passive technology to reduce the damage caused by collisions to pedestrians in a timely manner.
The Model 3 is equipped with only 6 airbags in the standard model, so it can be said that in terms of safety configuration, HanEV has ensured the safety of drivers and occupants and lay pedestrians to the greatest extent.
2. Assisted driving configuration.
In terms of assisted driving configuration, the Han EV has more functions than the Model 3, such as lane keeping assistance, 360-degree panoramic imagery, road traffic sign recognition, automatic parking entry, and reversing side warning.
In daily life, the function of road traffic sign recognition is of little use and belongs to chicken rib products, but in the case of many cars, narrow roads or narrow parking, 360-degree panoramic images and reversing car side warning functions can help drivers observe the surrounding conditions in real time and effectively avoid scratching. Even if you are sandwiched between two cars, the automatic parking function is convenient for parking in and out of the narrow position. In contrast, the entry-level Model 3 is only equipped with reversing images, which is a bit shabby for a model that costs more than 200,000 yuan.
3. Comfort configuration.
In terms of comfort configuration, the advantages of bydirhan EVs are even more obvious. The model 3's panoramic sunroof is non-openable, while the Han EV is equipped with an openable panoramic sunroof, which obviously brings better breathability. Han EV also has some unique configurations, such as: 220V power supply, passenger seat ventilation function, front multi-layer sound insulation glass and so on.
Not only that, Han EV's care for the rear passengers is also quite in place, such as: ventilation function, rear seat heating, rear boss key, rear seat electric adjustment and other configurations, providing a comfortable riding environment for rear passengers, even if they ride for a long time will not feel too tired. If you have the most money on hand, you can also opt for a rear massage chair.
In addition to the better riding comfort, the Han EV is also equipped with a rear multimedia control system for the rear passengers. Rear passengers can adjust the temperature, multimedia tracks, and volume through the touch screen on the central armrest, without the driver's operation, which improves travel safety to a certain extent. Although it is a family car, the Han EV can bring an executive-level riding experience to the rear passengers, and this series of features is not available in the Model 3.
4. In terms of vehicle warranty.
The warranty policy of BYD Han EV is: the first personal owner (non-operating) Sandian lifetime warranty, while the warranty policy of the whole vehicle is the warranty period of 6 years or 150,000 kilometers. For the three-electric system, BYD provides a lifetime warranty for Han, which is very rare in all new energy vehicle companies, and also shows that BYD has great confidence in its own three-electric products.
In contrast, the quality assurance policy of the domestic Tesla Model 3: its warranty policy is not the same as the different versions of the car, the low-end version is 8 years or 160,000 kilometers, and the high-end version is 8 years or 192,000 kilometers.
Imagine if the car has a service life of more than 8 years or 160,000 kilometers, then if the battery pack fails, or the mileage drops to affect the normal car experience, then you may need to replace the battery. The price of changing a power battery is not cheap.
A new energy pure electric vehicle, the cost of the power battery accounts for about 40% of the whole vehicle, and the manufacturing cost of the power battery is about 1100 to 1300 yuan / kWh, the actual price sold to the user is about 1500 to 1700 yuan / kWh, the difference in the middle is the manufacturer's profit. Taking the domestic Tesla standard endurance rear-drive upgrade version as an example, its battery capacity is 55/kWh, so it will cost at least 82,500 yuan to replace a complete power battery.
When you see this battery price, you are probably not willing to replace it at all, right? After all, the retention rate of new energy vehicles themselves is extremely low, 8 years of pure electric vehicles and not to mention whether there are second-hand car dealers willing to collect, even if they are collected, it is estimated that it is not worth the price of a new power battery.
At this point, in contrast, some domestic new energy vehicle companies, they do better, as long as they are the first car owners, basically three electric lifetime warranty.
All in all
Tesla has certain advantages in terms of power performance, assisted driving technology, brand influence, and driving texture, but in other aspects, it lags behind domestic independent brands. Especially after its localization, in order to further reduce costs, in all aspects of the car to reduce the allocation, the interior is simple and can not be looked at directly, the quality control is not as good as before, even Musk himself also openly admitted that Tesla has quality control problems.
In the appearance of the interior, functional configuration, charging efficiency, car machine system, cost performance and other aspects are a little bit of sincerity, these more intuitive car experience is far less than the domestic independent brand.
In short, if you have a lot of money, buy a car more focus on the "face", then the choice of Tesla is no problem, if you consider more comfort, cost performance and the economy of follow-up maintenance, then choose BYD, Xiaopeng, Weilai and other domestic independent brands is better.
