After finalizing the LiDAR and advanced driver assistance technologies, the new model is expected to be launched in the third quarter of this year.BYD Han, and other new information was recently revealed. According to the latest battery life and battery information released by the Ministry of Industry and Information Technology, the pure electric version of the new BYD Han is basically on par with the current model in terms of three-electric technology. The DM-i plug-in hybrid version of the new car will have major changes in the power system. In addition, the new BYD Han will also usher in new changes in chassis tuning.

The performance of the new car is ≥ the current one, will the price range be adjusted?

In the latest range information released by the Ministry of Industry and Information Technology, the new BYD Han only announced one specification. That is, the version with a battery capacity of 72kWh and a pure electric range of 605km. This specification is basically the same as the current "Han EV Honor Edition 605KM Front-wheel Drive Premium", and the corresponding guide price is 199,800 yuan. Excluding the four-wheel drive version, the 605km range is a medium performance of the BYD Han EV. There is also a long-range version with a range of 715km and a standard range version with a range of 506km.

So does the new BYD Han EV only offer a range of 605km? This may not be the case, at least the standard range version is likely to be retained. Although there is no relevant data in the new car declaration information and the range information disclosure. However, in the vehicle change extended information disclosure, a low-end model with a TZ200XSQ model motor and a maximum power of 150kW appeared. This configuration corresponds to the current "Han EV Honor Edition 506KM Front-Drive Premium Model", with a guide price of 179,800 yuan.

It is worth mentioning that compared with the new BYD Han EV, the performance of the three electrics is basically the same as the current one. The DM-i version of the new car has undergone large-scale changes in both the internal combustion engine, the motor and the battery. First of all, the internal combustion engine part of the plug-in hybrid system still maintains a displacement of 1.5T, but the model has been changed to BYD472ZQB. The most obvious difference from the current model is that the maximum power has been increased by 13kW (from the previous 102kW to 115kW). This is different from the 1.5L engine that was previously equipped with the fifth-generation DM technology, which actually had a certain decrease in the power of the internal combustion engine part. Simply put, the 1.5T version of the fifth-generation DM has undergone a performance upgrade, while the 1.5L version focuses on efficiency upgrades.

After the internal combustion engine was upgraded, the electric motor model of the new BYD Han plug-in hybrid model also changed to TZ210XYD, with a maximum power of 200kW. In terms of power alone, this motor is the same as the current DM-p Ares version rear motor, but the model is not the same. Only comparing the current economical DM-i version, the increase in the motor power part can reach 55kW. Not to mention the fifth-generation DM technology, which can further increase the total power of the electric drive by decoupling the strong connection between the P1 motor and the internal combustion engine. If the drive structure is not rigorously removed, only the performance parameter growth of the internal combustion engine and the motor is calculated. The new BYD Han plug-in hybrid can be comprehensively improved by about 68kW, which is more than 92 horsepower.

As mentioned earlier, the fifth-generation DM technology can decouple the connection between the P1 motor and the internal combustion engine. So in addition to the higher efficiency of the new internal combustion engine itself, the presence of two motors can reduce the speed of the internal combustion engine when it intervenes in direct drive to a greater extent, thereby reducing the power-feed fuel consumption and optimizing NVH. According to information released by the Ministry of Industry and Information Technology, the power-feed fuel consumption of the new BYD Han plug-in hybrid is 4.7L/100km. With greatly enhanced performance, its power-feed fuel consumption is still reduced by 0.4L/100km.

As for the obvious improvement of both the internal combustion engine and the motor, will the price of the new BYD Han rise? The answer is probably no. Because in the power battery part, relying on the efficiency advantage of the fifth-generation DM technology, the new car uses a battery pack of about 13kWh in the entry-level version, and the high-end version continues the current battery capacity of about 18kWh. This battery combination is similar to the idea of ​​the previous models using the fifth-generation DM. The low-end model can save at least 5 kWh of electricity, free up enough cost space, and may even bring surprises in the final price.

Is the chassis more comfortable, especially at highway speeds?

According to the information released by the Ministry of Industry and Information Technology, in addition to the improvement of the three electrics and performance, the new BYD Han also has interesting changes in the chassis. First of all, in the new car declaration information, whether it is a pure electric or plug-in hybrid version, the rear track has been expanded to 1650mm, while the front track is still 1640mm. Considering that other body data has basically not changed, especially the body width is still 1910mm, the new car simply increases the rear track.

The 10mm wheelbase difference may not seem like much, but if we only consider economy passenger cars, this gap is not small.BYDIn the vehicle model system, considering the size factor, that isBYD Tang, its front track is 20mm longer than the rear track. This is because the latter is an SUV with a higher ground clearance, and the relatively wider front track can improve stability in corners. Of course, it will sacrifice a certain amount of steering accuracy. However, this is not a core issue for SUVs.

Back to the perspective of sedans, except for the case where the front and rear wheel tracks are equal, in most cases the rear wheel track is slightly larger than the front wheel track.Honda CivicThis kind of case where the rear track is 28mm larger than the front track is still rare.Toyota Corolla, the rear track is only 6mm longer than the front track. By analogy, is the new BYD Han going to enhance its sports handling performance? Especially after the upgrade of the three-electric performance of the new car as mentioned earlier. But the reality may be just the opposite. The tuning direction of the new car is actually comfort.

Let's take the Honda Civic as an example. The reason why this sports car with sporty characteristics can have such a large difference in front and rear wheel tracks in the field of civilian cars is actually due to the factor of reducing the front wheel track. Its 1547mm front wheel track does not look narrow, but combined with the body width, its proportion is not even as good as the Toyota Corolla next door. But in terms of rear wheel track, whether in terms of value or proportion, the Civic is much wider than the Corolla. Therefore, the Honda Civic can theoretically obtain better steering accuracy, but it will also relatively sacrifice some stability.

Looking back at the new BYD Han, the new car has not changed the value of the front wheel track and the ratio to the body width. In essence, it simply upgraded the rear wheel track, and as a C-class car, the upgrade scale is also quite restrained. The reason for making this adjustment is probably because of the straight-line stability brought by the widened rear wheel track. And the stability of the rear row of the car in corners.

Of course, under the premise that it is temporarily impossible to obtain whether there are clear changes in the chassis structure, the improvement of the new car's effect may be relatively limited based only on the tuning skills. For example, if we only discuss the effect after the wheelbase is adjusted, the performance in large-angle control may be limited. However, in scenes such as highways and expressways that do not require large-angle steering wheel movements, it should be able to achieve a certain improvement. Combined with the new BYD Han's added laser radar and other perception hardware, as well as the previous technical calculations of its intelligent driving solutions, it itself is also a priority to meet the excellent high-speed scene no-map NOA performance. Therefore, considering the dimensions of three-electric performance, chassis tuning, and intelligent driving, the new BYD Han is expected to bring more comfortable, stable and worry-free high-speed performance.
