Which of BYD Han EV and Xiaopeng P7 is better than Model 3?

[Shopping Guide Channel of Pacific Auto] The launch of BYD Han EV makes Xiaopeng P7 one more competitor, and from the perspective of the positioning of the two cars and the guide price, the relationship between the two can be described as "tet-for-tat". However, since everyone has a basic understanding of the appearance and interior, the shopping guide of this article will also talk about different things for you.

Let’s first talk about the differences between the two cars.

First look at the positioning

P7 is Xiaopeng’s attempt to face high-end pure electric coupes. It is also the second mass-produced model of Xiaopeng Motors. Its "success or failure" is for Xiaopeng Motors. It is very critical, because Xiaopeng Motors needs to rely on P7 to stand out, thereby bringing higher brand premium capabilities. Therefore, the birth of P7 can be said to be a "benchmark to Tesla", but it hit the market at a price lower than Model 3 (the Han EV was not yet on the market at that time) to enhance the brand image.

And Han EV, it is BYD's latest flagship sedan, and it can be regarded as BYD's "Ding Li" masterpiece this year. The performance of Han EV in the market will also be related to BYD's role as a leader in the domestic new energy vehicle field. Therefore, whether it is Xiaopeng P7 or Han EV, their respective position in the brand and role playing in the market are all related to their next development direction.

Price overlap

Han EV's price range after comprehensive subsidy is 229,800 to 279,500 yuan, and Xiaopeng P7's price range after comprehensive subsidy is 229,900 to 349,900 yuan. There is an overlap in price between the two, especially starting sales. The price difference is only 100 yuan. However, judging from the current models, the P7 has launched a total of two power versions, four endurance versions, and eight models with different configurations, while the Han EV has only three models. In terms of options, the P7 is more abundant. .

In addition, as far as the price difference between each model is concerned, the Xiaopeng P7 basically maintains at around 10,000 yuan, while the Han EV has opened the gap between low, medium and high-end models internally, with a price difference of 25,000 yuan. However, the positioning of each model version is relatively easy to distinguish. For example, Han EV’s low- and mid-range models are 605km long-range models (single-motor front-drive mode), while the advantages of high-profile models are dual-motor four-wheel drive In the mode, it can accelerate from 100 kilometers to 3.9 seconds, but the endurance is slightly lower (550km endurance).

Differences in basic configuration

Here, let’s start with the main model to see who is more sincere. The 706km endurance version of Xiaopeng P7 abandons many technological configurations such as intelligent network connection and autopilot system. Therefore, although the endurance is attractive, the 670km endurance version will be the main model, so the price is 266,900. Yuan’s rear-drive ultra-long battery life smart enjoyment version has the highest attention. Corresponding to this, we take the ultra-long battery life version of the Han EV premium model (255,800) as an example to take a look at their configuration advantages.

For battery life, the Xiaopeng P7 has more options, and undoubtedly does have an advantage. In terms of basic configuration (the intelligent driving assistance system is described in the next summary alone), the passive safety of Han EV is more complete and more The rear side airbags and the front knee airbags are installed. In addition, Han EV also pays more attention to the configuration of seat comfort, such as the rear boss button and rear backrest adjustment, which are not available on the top model of the P7.

drag coefficient, this plot is very bloody.

Speaking of "drag coefficient", this plot is really a bit ups and downs: Xiaopeng P7 just won praise in the industry with 0.236Cd in October last year, but it has not yet officially launched. Was "cut Hu" by Han-Han was slightly better with 0.233Cd. What is the concept of

0.233Cd? is an example for you to understand better: the drag coefficient of global mass-produced cars is within 0.235, and currently there are no more than 10 models. Take BYD Han EV as an example, every time the drag coefficient decreases by 0.01, the car's endurance will increase by 8 kilometers. So, can the Han EV run a few kilometers longer than the P7? (Students with good science scores can help calculate, the calculation formula is shown in the figure below)

The wind resistance coefficient can reflect how much energy the car consumes to overcome air resistance when driving , Is an important indicator in automobile aerodynamic design, mainly determined by the shape of the vehicle. So we must also admit that BYD Han’s design is indeedNiu, but what I want to say is that if you are only driving in the city, the 0.003Cd difference between Han EV and Xiaopeng P7 is really negligible, because you can’t run fast at all, but if you often Running at high speeds, this does have some impact.

Intelligent driving assistance system, P7 dishes

It should be said that starting from Han, BYD is finally equipped with a relatively complete L2-level assisted driving system DiPilot, and Han is also stronger in intelligent driving assistance compared to BYD’s previous models (Changed a new supplier), that is to say, from the beginning of Han, BYD began to be intelligent in the true sense. However, for Xiaopeng P7, intelligence has always been the main direction of Xiaopeng, so Xiaopeng P7 also pays more attention to the layout of intelligence. Its XPILOT 3.0 automatic driving assistance system can achieve L3 conditional automatic Driving, and also made many localization upgrades.

However, we haven’t experienced BYD’s DiPilot system yet, so I don’t want to comment too much. Let’s talk about its core for now: it is infinitely close to the L3 level of automatic assisted driving, such as the automatic emergency brake assist system. , Forward collision warning system, ACC adaptive cruise, lane centering, and automatic lane change can all be achieved. More importantly, Han can also be upgraded through OTA, which is somewhat expected.

In addition, Han EV and Xiaopeng P7 also have very different attitudes and ways of dealing with intelligence. Han EV has the "Huawei" endorsement, which opens up the interconnection between Han EV and Huawei mobile phones, and can also provide users with smart functions through Huawei HiCar, but in essence, this improvement should still be led by Huawei.

But for P7, it firmly holds the autonomy in its own hands, and it has a very deep OTA capability. As can be seen from the hardware architecture in the figure above, the hardware support of Xiaopeng P7 can even be described as "exaggeration", and in terms of automatic driving assistance capabilities, it can be regarded as an "end-to-end" self-developed model. In addition to intelligence, Xiaopeng P7 also emphasizes its technological attributes. For example, it also aims at the entire ecology behind Alibaba. It can use "car payment" for Xiaopeng charging piles, car applications, Alibaba applets and other service scenarios. Make a payment.

Talk about battery technology and safety

Han EV is equipped with a lithium iron phosphate blade battery with a capacity of 76.9kWh, which is BYD’s “black technology”. The Xiaopeng P7 is equipped with a ternary lithium battery from Yiwei Lithium Energy, with a capacity of 70.8kWh/80.9kWh.

There have been a lot of reports about the blade battery of Han EV before, because the "needle penetration test" made everyone's attention focused on the word "safety". Interested friends can pay attention to our technical article (Portal: The steel needle pierced the blade battery was shocked), here I will only list the highlights.

1

The most intuitive and obvious improvement: the volume utilization rate of the battery has been improved by changing the battery structure (from 40% to 60%).

2

From the perspective of the thermal safety of battery materials: Blade batteries have narrowed the energy density gap with ternary lithium batteries under the premise of taking advantage of thermal safety.

3

However, there are shortcomings: in an extremely low temperature environment, the discharge capacity of ternary lithium is higher than that of lithium iron phosphate.

Xiaopeng Motors has also done tangible things in terms of safety. In June, it applied to the State Intellectual Property Office for a patent on the protection method for thermal runaway of electric vehicles. The main reason is that when the thermal runaway occurs in the car, the car The built-in fire extinguishing device can automatically sense and directly extinguish the power battery, thereby reducing the risk of vehicle explosion (see the figure below).

In short (note, in theory), BYD has optimized the structure, and the thermal stability of the cell material is higher than that of Xiaopeng P7, but in extreme low temperature environments, Xiaopeng P7 has more advantages.

space utilization and sound insulation

compare the body size of the two cars, the Han EV is longer, and the Xpeng P7 has a longer wheelbase, but both are over 2.9 meters, so their riding space can be guaranteed. . If you don't have any feelings for this size, you can make up for the size of Model 3. Well, Han EV and Xiaopeng P7 are both larger than it.

z102In terms of luggage compartment space, the Xiaopeng P7 has a volume of 440 liters, but the rear seats can be folded down proportionally. There is currently no data on the luggage compartment volume of the Han EV, but the difference between the two should not be too large, except for the Han EV The rear seats cannot be downed proportionally, and the loading space is not as flexible as the Xiaopeng P7. However, although the rear seats of Han EV do not support reclining, its rear seats support backrest adjustment and are also equipped with one-button electric adjustment, which makes the ride more comfortable and luxurious. Of course, the premise is that you have Buy the flagship four-wheel drive high-performance version (279,500). In addition, a channel is designed in the middle of the rear seats of the Han EV, through which the trunk can be taken.

Regarding the storage space in the car: the space of the two cars is definitely sufficient. Here are the characteristics of each. The biggest highlight of Han EV is that the space of the co-pilot glove box is good, and it is very advantageous in the same level. The Xiaopeng P7 is equipped with a front trunk, and Han EV does not have this configuration.

finally talked about sound insulation. Since the Han EV has not been tested yet, there is no data comparison between the two cars yet, but after a test drive, I personally feel that the performance of the Han EV is better in terms of sound insulation.

Finally, let’s talk about the personal summary of the launch of the two cars

. Let us turn our focus on the Model 3 to our own excellent products, making two more medium and large pure electric cars less than 300,000 yuan. As for who to choose, to be honest, Han EV and Xiaopeng P7 are no different. Simply, the editor sorted out the respective advantages of the two vehicles, you can make a choice according to your needs.

The advantages of BYD Han EV can be roughly summarized as follows: BYD lithium iron phosphate blade battery ensures the safety of the car, which is their "black technology". The acceleration performance of 100 kilometers in 3.9 seconds is strong. Of course, the premise is that you have to buy the top model (279,500). The price range of 21.98-27.95 million is really more cost-effective. The key is that the MD version is also provided, which is very competitive. The sound insulation of the vehicle is well done, and it would be even better if it was paired with a good sound system. The advantages of

Xiaopeng P7 are: The cruising range still maintains a very advantageous level in the industry, and there are many models and a wider choice. However, the 706km endurance model is not in volume, and the 670km model is more cost-effective. The driving assistance system has more advantages than Han EV, pays more attention to intelligence and technological performance, and has a deep OTA capability.
