With the rise of oil prices, many people began to turn their attention to new energy vehicles, and recently there have been a number of new energy vehicles cutting leeks, either raising prices or reducing configuration and so on. In short, they should try to make a profit anyway. But for some consumers, if it is because of rising oil prices or pure trams can't satisfy poetry and distance, then I personally suggest you consider your own brand of hybrid cars. For example, at the beginning of this year, "three hybrid cars" broke into everyone's field of vision. They are Changan UNI-K iDD, WEY DHT and BYD Tang DM-I.
If you think this is a product guide, Brother G may disappoint you a little, because today we will help you explain from a technical point of view, which of the three cars, Changan UNI-K iDD, WEY Moka DHT and BYD Tang DM-i, is closer to your car scene?
First of all, from the basic power systems of the three models, Changan UNI-K iDD, WEY Moka DHT and BYD Tang DM-i all use 1.5T turbocharged engine as the core power source, and the power data of the three models are not much different, among which the most eye-catching data are the maximum net power of 122kW and the peak torque performance of 255nm brought by Changan UNI-K iDD. In addition to some differences in power data, the three cars are also different in transmission. Among them, Changan UNI-K iDD adopts 6-speed three-clutch electric drive transmission, WEY Moka DHT adopts 2-speed DHT transmission, and BYD Tang DM-i adopts E-CVT transmission.
Let's talk about the 6-speed 3-clutch electric drive transmission adopted by Changan UNI-K iDD. In fact, this seemingly incomprehensible and tall transmission form is a 6-speed power shift, and there is a clutch at P2 position to control the drive motor, thus forming a 3-clutch mode. Therefore, compared with the other two cars, Changan UNI-K iDD has stronger high-speed driving ability, and the top speed of the whole vehicle can reach more than 200 km/h. In addition, the addition of 6-speed powershift also improves the driving pleasure of the whole vehicle. Next is the 2-speed DHT transmission carried by WEY Moka DHT, which may be familiar to everyone. Its essence is to provide lower engine speed when the vehicle is driving at high speed, and the overall approach is more straightforward. The E-CVT transmission used by BYD Tang DM-i is more about taking care of the medium and low speed driving of vehicles. BYD Tang New Energy already has Tang DM, Tang EV and other models. DM-i was born to save fuel, and the E-CVT transmission can also directly drive the vehicle by the engine.
We have a general understanding of the differences between the three models in terms of engine and transmission system. Next, let's take a look at the performance of the three models in terms of motors and batteries, as well as their endurance.
It can be intuitively seen from the above table that WEY Moka DHT has a stronger vehicle performance foundation. Its performance version adopts the combination of front and rear double motors, and cooperates with 1.5T turbocharged engine. The maximum power of the whole system is 355kW, and the peak torque performance is 762nm. If the engine performance is slightly inferior, it has an overwhelming advantage in comprehensive power, and the resulting performance is enough to make it. However, in addition to stronger comprehensive performance data, the battery capacity of WEY Moka DHT is the largest among the three cars, with a ternary lithium battery capacity of 39.67 kWh and a pure battery life of 204 kilometers under WLTC, almost twice that of Wuling Hong Guang MINI EV. So seeing this, I think the strategy of WEY Mocha DHT is already obvious, that is, to pursue more extreme power experience and more lasting endurance performance, which is only in the state of plug-in and hybrid. If pure electric vehicles are introduced in the future, it may bring us more surprises.
Compared with WEY Moka DHT, BYD Tang DM-i has obviously maintained its economic side. Among these three cars, not only the battery capacity is smaller, but also the pure electric cruising range is not excellent. The NEDC pure electric cruising range of low-profile models is only 52 kilometers. However, the motor data with greater power and torque can bring stronger low-speed pure electric performance to BYD Tang DM-i, regardless of vehicle weight and energy efficiency. But even so, it can't stop BYD Tang DM-i from being more economical and more suitable for urban products.
However, compared with the above two cars, the positioning of Changan UNI-K iDD seems to be in between, and from the official guide price of Changan UNI-K iDD, it is also the cheapest of the three cars, which already shows that Changan UNI-K iDD has a higher cost performance on the technical basis. For example, for the first point, Changan UNI-K iDD also has a battery pack capacity of more than 30 kWh, which can bring 130 km of pure electric cruising range. The second point is that Changan UNI-K iDD also has a 3.3 kW external release function. Third, the fuel consumption performance of Changan UNI-K iDD can reach 5 liters/100 km even in the lowest charging state. Therefore, to sum up, Changan UNI-K iDD is more cost-effective than WEY Moka DHT, and can provide better high-speed working conditions than BYD Tang DM-I. ..
Finally, the conclusion is that although independent brands are constantly making efforts in the field of new energy, the technical basis of different concepts has created products with different characteristics, so how to choose these products depends on their actual car use scenarios.
