BYD, give me back my gearbox! Tang DM-p was upgraded reversely, which disappointed the old car owners.

At 8 o’clock on the evening of June 9, the long-awaited Tang DM-p finally officially appeared for pre-sale, with a pure battery life of 215 kilometers, a super intelligent electric four-wheel drive, an acceleration of 4.3 seconds at zero, and a fuel consumption of 6.5L per 100 kilometers, which is a performance benchmark of this level. Perhaps my expectations are too high. As the first generation of Tang car owners, I am slightly disappointed with the new Tang DM-p, and even think it is a compromise between technology and market.

Dynasty series is BYD’s pioneering work. Since the first generation of Qin and Tang Dynasties, it has established its position as a leader in new energy vehicles. In particular, the 542 strategy, Tang Zhanfanbang, eclipsed the joint venture car at the same level! Zero acceleration of 4.9 seconds, full-time electric four-wheel drive, in the 200,000-class SUV, Tang Yi rides the dust! Even under a million, there are few opponents. Since then, BYD has gained the first batch of fans, and I am one of them.

The first batch of Tang car owners, the pride of domestic cars was rooted in their bones. At that time, the 2015 Tang didn’t even have a small BSG motor, and it was said to be an oil tiger, but I could drive it below 6L (the road conditions were smooth), and even went to
get away
) specific fuel consumption. The running-in between people and cars has reached such a level as an armband, an automatic transmission car, and I can even control the engine rpm through mode switching and throttle depth, just like manual transmission.

In 18 years, the second generation of Tang Dynasty went on the market, and started the family design of Longyan, upgraded the BSG small motor, and the zero-hundred-speed acceleration was also improved to 4.5 seconds, which can be said to be a brand-new look from the inside out. At that time, the president of Volkswagen even came to Wan Li for a test drive, so that he was caught speeding and made a wave of advertisements for BYD for free.

Perhaps the starting point of Tang is too high. This time, Tang DM-p did evolve and upgrade in some places, but it also lost something. The prospective car owner may be happy, but for an old car owner like me, he is slightly disappointed. Tang DM-p still hasn’t evolved to the perfect appearance in my heart, and there are some grooves, so I really can’t spit it out.

First, what about the gearbox?

DM-i doesn’t need it, because it focuses on economy and fuel economy. Han DM-p can also use no gearbox, and the passability of the car determines that it can only take pavement. But as an SUV with main performance,Represents poetry and the distant Tang DynastyI think the gearbox is necessary.

EHS electric hybrid system can be more fuel-efficient and smooth, and the super intelligent electric four-wheel drive is realized by three-in-one rear electric drive, and its stability and difficulty relief are not inferior to the previous version. When using the gearbox, it is inevitable that there will be a sense of shifting, which will reduce the driving experience and increase fuel consumption. However, the gearbox has two advantages that ECVT can’t compare. The first isThe engine can be involved in the full speed range., the power bonus is higher. The second isOil and electricity systems are independent of each other, which can form double insurance..

ECVT (including all the existing DHT in 2nd and 3rd gears) has no starting gear, so once the battery, motor and circuit system fail, the engine cannot drive the vehicle alone. And the hybrid gearbox, such as the old Tang and Han DM, can run on pure oil, at the very least, the safety is more secure, and it will not squat halfway. It is more reliable when you drive long distances, even when you cross long distances.

Second, upgrade 2.0T to 1.5T?

Compared with the 2021 Tang DM, the power of Tang DM-p has not been significantly improved, and the official announcement is 4.3 seconds faster than the actual measurement. However, the old Tang DM was realized by 2.0T engine+dual motors with total power of 394kW, while the new Tang DM-p was realized by 1.5T engine+dual motors with total power of 480kW.

We don’t blow black, the displacement is small, the fuel consumption will inevitably decrease, and on this basis, the performance has not weakened, which can be regarded as an improvement. The old Tang DM lost 7.5L of electricity and fuel consumption, while the new one was reduced to 6.5L..

In addition, the thermal efficiency of the new 1.5T Xiaoyun engine is more than 40%, and the noise and vibration are obviously better than the old 2.0T If the new and old models are compared, the new NVH must be far superior to the old ones. Although I have not measured this, I can tell from the technical details.

However, it is 1.5T after all. In order to make the power reach the previous high standard, the motor power has to be increased, and in order to maintain the output of the motor, the battery has to be increased. So this is the Tang DM-p with a battery life of 215Km. butDon DM-p, in my mind, it should be 2.0T!

2.0T high thermal efficiency engine, BYD487ZQD, the thermal efficiency is actually not too high, 39% is enough, and the soul of Tang is not fuel-efficient. I think the fuel consumption of 7.5L is acceptable, because if it can be charged at home, it will still be driven by pure electricity most of the time. My old Tang needs 9L for electricity consumption, but I also have to worry about the expiration of gasoline. For most people, 80Km pure battery life is enough.

Third, don DM-p is still

BYD’s marketing level is a long story. before
The four-wheel drive version is called Song PLUS DM-i AWD, which is the same as adding a rear motor on the basis of the EHS hybrid of DM-i. And when I got to Han,
In addition, the rear motor realizes four-wheel drive, because the pure battery life is longer, it is called DM-P. Is there any rule for this naming? Who can tell me what is the difference between DM-i AWD and DM-p? Is the motor more powerful?

In fact, according to the classification defined by BYD itself, the current DM-p of Tang and Han should be called DM-i AWD. Because DM-p is defined as the ultimate performance, regardless of fuel consumption, it should be a 2.0T engine+a hybrid special gearbox with a starting gear (which can be an advanced version of DCT). On this basis, plus a large motor and a large battery necessary for a large motor, it should not be a problem to have a pure battery life of 200Km and a break of 4 seconds.

As a car, the solution of DM-i AWD (cash DM-p) is indeed better than the solution with gearbox. However, as an SUV, I still think that a gearbox is needed to add a heavy insurance to poetry and the distance.

In fact, from the change of naming, we can also see the internal entanglement of BYD. If the technical scheme of early DM-p was determined, there would not be such a freak as AWD on Song Plus DM-I. Maybe just call it
DM-P. I guess, when Song PLUS DM-i AWD was released, BYD didn’t deny that DM-p had a gearbox, and finally, for various reasons, it had to compromise with the market.

Fourth, high-cost solutions cut off the possibility of low prices.

Why does Tang DM-p need 215Km pure battery life? In fact, for most families, the average mileage of a year is 10,000 kilometers, and the average is only about 30Km kilometers per day. Therefore, it is enough to travel in the urban area with pure electricity for 80Km. Even if you run a little farther occasionally, the mileage of pure electricity is not enough. It is nothing more than using some oil. The long battery life is meaningless. But why do the pure battery life of Tang and Han DM-p exceed 200Km?

Because this is necessary for large motors, the battery pack must be large enough to support the voltage required for high power output of large motors! And the cost of the battery is real money, so the price of this generation of Tang Han is much more expensive than the previous generation. You can say it’s worth the money, but it’s not friendly to some friends with insufficient budget.

Fifth, the strength comparison of Tang DM-p products.

The above spit is mainly because I don’t agree with BYD’s technical route, butAs far as Tang DM-p is concerned, the improvement is still huge.. Even if it sells for more than 300 thousand, its product strength at this price is still the strongest, and the only thing that can compete with it is only.
DHT PHEV, plus 2021 Tang DM, we put the three cars together to compare the product strength.

1. compare mocha DHT PHEV:Mocha There are only two configurations of PHEV, one is the 252Km distinguished model equivalent to Tang DM-i, which has no advantage in price and battery life. The fast charge is only 60W, and it takes one hour to charge the battery to 80%. The advantage is that the power is better than that of Tang DM-i 252Km, which is 7.4 seconds, and Bitang DM-i’s performance of 8.5 seconds is more than one second faster. Compared with the two-drive version, it is obvious that the newly released Tang DM-i 252 honor is more worth buying.

The four-wheel drive version, which corresponds to Tang DM-p, is slightly inferior in power, but the gap between 4.8 seconds and 4.3 seconds does not make much sense for home use. Tang DM-p has longer battery life and stronger fast charge. The specific configuration is basically the same horizontal line, while Tang DM-p has a wide temperature range heat pump air conditioner, which has obvious advantages in winter endurance.

In addition, Mocha has five seats, while Tang provided seven-seat and six-seat versions.

Previously, my evaluation of Moka DHT PHEV was before the release of Tang DM-p, and it was 300,000 SUV with the highest cost performance, and there was no one. Sure enough, after the release of Tang DM-p, the most cost-effective 300,000 SUV was taken away.

2. Compare 21 Tang DM models.The price ranges of the two cars do not overlap, so they do not constitute direct competition. Tang DM has only two advantages. The first is its low price. Although it is a product of the previous generation, its performance is not weak. The second is that the oil and electricity systems are independent of each other, which is equivalent to double insurance. However, in other respects, it is definitely a penny for a penny. The pure battery life of Tang DM-p is 215Km. You may not need it, but the money is spent in place, and the surplus is better than nothing. Moreover, the power is insufficient and the fuel consumption is much lower than that of the same class fuel vehicle.

In addition, the biggest improvement is assisted driving. In the past, Tang DM’s assisted driving was only L2 level on the passing line, and the top models only had parallel auxiliary function. The new Tang DM-p has reached the level of quasi-L3, ACC adaptive cruise supports stop-and-go mode, forward and backward travel tips, blind spot monitoring, active lane keeping system, automatic parking in the whole scene … and the safety has also increased by one level.

The second is fast charging. Previously, the most popular voice of old riders was the fast charging function. For Tang DM with 80Km battery life, fast charging is of little significance, because no matter how fast it is filled, it can only run 80Km. However, for the pure battery life of 215Km, it is worthwhile to charge 80% in 20 minutes. 200Km requires 13L of oil. If it can be recharged, it can save more than 100 yuan of oil money.

Sixth, Tang DM-p, DM-i, DM and EV purchase suggestions.

1. It is recommended not to be obsessed with SUV. If it is only for urban transportation, I recommend Han DM-p more. The budget is more than 280 thousand,
More fragrant.

2, there is no demand for four-wheel drive, home to buy Tang DM-i 112Km battery life version, starting at 202,800, cheap is the last word! 112Km pure battery life is enough for most families. The long battery life of 252Km is 80 thousand expensive, which is highly recommended! If you have that budget, you might as well buy DM-P.

3. I want to buy a car after retirement in go on road trip, and I recommend 21 models of Tang DM on the grounds of double insurance. If you have enough budget and don’t go to too remote places, you can also choose Tang DM-p with fast charging, and the cost of comprehensive vehicles is lower.

4. Do not travel far, meet the needs of family cars,
Since you don’t travel far and drive in the city, the two drives will be enough. Unless you are in a northern city, you need to deal with icy roads. The battery life depends on your travel radius. There is no difference between 730Km and 500Km for a pure tram, only the difference between sufficient and insufficient.Make sure you don’t plan to drive long distances. EV smells better than DM-i and DM-p, although it is more expensive..

5. Tang DM-p configuration suggestionsPersonally, the most cost-effective one is the middle-equipped exclusive type, which has a lot more active safety configuration and comfort configuration than the low-equipped one, and can be equipped with a six-seat enjoyment combination suit, with a 2+2+2 seat layout for 10,000 yuan, and the second row of seats can be upgraded with ventilation, heating, massage and lumbar support, which is very cost-effective. Low matching is not recommended, and the loss of 20 thousand yuan difference is too much. The top matching mainly adds an active suspension, and supports full-scene automatic parking, Brembo brake calipers and differential locks. Of course, the budget is sufficient, but the cost performance is not higher than that of the middle matching model.

Write it at the endIn fact, Tang DM has basically reached the ultimate performance of family cars in the previous generation, so that it is difficult for the new model to achieve any substantive breakthrough. Moreover, although Tang is the flagship model of the dynasty family, it is not the top in BYD’s product system, the legendary high-end brand (starry sky? It is getting closer and closer to us, whether it is spit or disappointment, it must still be admitted that Tang DM-p is a 300,000-level SUV with the strongest product strength. Even if there is only a small step forward, it is also breaking through yourself.
