02 | Product Competitiveness Analysis

The BYD Sea Lion 07 EV is positioned as a pure electric mid size vehicle, mainly aimed at household scenarios. Its overall performance is well-balanced and comprehensive in terms of space, configuration, and power. Taking into account brand influence, vehicle positioning, and price range, I have ultimately selected two competing models for it: the Arctic Fox Alpha S5 and the Deep Blue L07. In terms of appearance, although all three models feature a sporty and technological style, they each have their own emphasis overall. The body lines of the BYD Seal 07 EV are smooth and stretched, with a simple and atmospheric design that balances luxury and sportiness. The design language of the Arctic Fox Alpha S5 is more avant-garde and exquisite, with a low slung posture and a smooth waistline, creating a strong technological atmosphere. The Deep Blue L07 emits a distinct sporty coupe style overall, with a highly aggressive visual effect that caters to the preferences of young consumers. According to the price range, the entry-level model of the 2026 Arctic Fox Alpha S5 has the lowest price at 104800 yuan. The most expensive top of the line model is the 2026 BYD Sea Lion 07 EV, which costs 189900 yuan. In terms of the number of car models, due to the fact that both the 2026 Arctic Fox Alpha S5 and the 2026 Deep Blue L07 offer two types of energy, there are a relatively large number of car models. The 2026 BYD Seal 07 EV is a pure electric version, with a total of 2 configurations available.

In terms of vehicle configuration, we have selected models with prices as close as possible. By comparison, the BYD Sea Lion 07 EV has demonstrated strong overall competitiveness with its balanced and comprehensive configuration performance. Although the performance parameters are not as good as the Arctic Fox Alpha S5 with a dual motor four-wheel drive system, the CLTC pure electric range of the BYD Seal 07 EV reaches 705km. The second-generation blade battery combined with flash charging technology can effectively alleviate users' range anxiety, and its practicality is more outstanding.

By screening the complaint data of BYD brand in the past year, it can be found that there are relatively more complaints about "rusting of the car body". Further analysis reveals that the complaint is mainly focused on models such as Qin PLUS, Song Pro New Energy, and Destroyer 05. Due to the lack of official promotion that the BYD Seal 07 EV has undergone a comprehensive upgrade in its body rust prevention technology, it can be assumed that there is a probability of the new car experiencing the same issues mentioned above. However, the actual situation will be determined after it has been on the market for a period of time.

With the continuous development of China's automobile market, the level of brand pre-sales/after-sales service and the quality of the purchasing experience have gradually become important factors affecting consumers' final purchase.

From the perspective of service complaints, "system upgrade issues" have become a more concentrated service issue for car owners to complain about. Through further analysis, it can be concluded that the problem mainly comes from the Sea Lion model.

In terms of measuring the reputation of new car after-sales service, we will analyze the response of enterprises to car owner complaints, and make relatively objective predictions about the future reputation of new car after-sales service. According to data from Chezhiwang, the complaint response rate of BYD brand in the past year was 100%, indicating that the manufacturer attaches great importance to the demands of car owners.

In addition, the non operational vehicle of the first owner can also enjoy a lifetime warranty for the three electric system (please consult the local dealer for details). After purchasing a vehicle, it is necessary to involve the daily maintenance of the vehicle. At this time, the number and distribution of brand dealer stores are very important, and may even have a certain impact on whether consumers purchase the brand model.
