1. Who has lower car usage costs for urban driving?

Answer: In urban commuting scenarios, the Song PLUS DM-i has slightly lower usage costs. Let's calculate based on the common 110km/115km pure electric range versions: assuming a daily commute of 50km, charging once a week, and the electricity price is 0.6 RMB/kWh. The Song PLUS DM-i has a battery capacity of 18.3kWh, and the cost to fully charge is about 11 RMB, which can drive 110km, converting to an electricity cost of 0.1 RMB per kilometer. If driving in battery-depleted state without charging, the official battery-depleted fuel consumption is 4.5L/100km, and 92# gasoline is 8 RMB/L, resulting in a fuel cost of 0.36 RMB per kilometer.

The Galaxy L7 has a battery capacity of 18.7kWh, and the cost to fully charge is about 11.2 RMB, which can drive 115km, with an electricity cost of about 0.1 RMB per kilometer. The battery-depleted fuel consumption is 4.8L/100km, with a fuel cost of 0.384 RMB per kilometer.

Calculated based on annual driving of 15,000km, if charging is convenient (80% of driving in pure electric mode), the annual usage cost of the Song PLUS DM-i is about (15,000 × 80% × 0.1) + (15,000 × 20% × 0.36) = 1200 + 1080 = 2280 RMB. The annual usage cost of the Galaxy L7 is about (15,000 × 80% × 0.1) + (15,000 × 20% × 0.384) = 1200 + 1152 = 2352 RMB. The gap between the two is not large, but the Song PLUS DM-i has a slight advantage. If charging is inconvenient and the proportion of battery-depleted driving is high, the gap will be more obvious.

2. What are the differences in battery safety and technology between the two cars?

Answer: In terms of maintenance costs, there is not much difference between the two cars, but the Song PLUS DM-i has a more flexible maintenance cycle.

The official maintenance cycle of the Song PLUS DM-i is 7500km or 6 months (whichever comes first). The cost of minor maintenance (replacing engine oil and oil filter) is about 500 RMB, and the cost of major maintenance (replacing engine oil, oil filter, air filter, air conditioning filter, etc.) is about 1200 RMB. Calculated based on annual driving of 15,000km, the annual maintenance cost is about 1000-1500 RMB.

The official maintenance cycle of the Galaxy L7 is 10,000km or 12 months (whichever comes first). The cost of minor maintenance is about 600 RMB, and the cost of major maintenance is about 1300 RMB. Calculated based on annual driving of 15,000km, the annual maintenance cost is about 900-1400 RMB. Although the single maintenance cost of the Galaxy L7 is slightly higher, the maintenance cycle is longer, and the overall cost is basically the same.

In terms of residual value, the Song PLUS DM-i has a greater advantage. According to the "2024 China Automobile Residual Value Report" released by the China Automobile Dealers Association, the one-year residual value rate of the BYD Song PLUS DM-i is 78%, and the three-year residual value rate is 65%. As a model with a relatively short market time, the one-year residual value rate of the Galaxy L7 is 72%, and the three-year residual value rate is not yet clear, but it is expected to be lower than that of the Song PLUS DM-i. The main reason is that the Song PLUS DM-i has a large market ownership, sufficient supply of spare parts, convenient maintenance and repair, and higher recognition in the used car market.

4. Is the pure electric range sufficient? Will the range be reduced in winter?

Answer: The pure electric range of both cars can meet the daily urban commuting needs of most families. The range will be reduced in winter, but the impact is manageable.

In terms of official pure electric range, the Song PLUS DM-i has two versions: 55km and 110km, while the Galaxy L7 has two versions: 55km and 115km. For most families, the daily commute distance is within 50km, and the pure electric range of the 110km/115km version can fully meet the weekly commute needs, requiring only one charge on weekends. The 55km version is suitable for users with inconvenient charging – daily commutes can be driven in pure electric mode, and no refueling is needed for short trips.

In low-temperature environments in winter, the activity of lithium batteries will decrease, and the pure electric range will be reduced. According to actual tests by authoritative media, in an environment of about -5℃, the actual pure electric range of the Song PLUS DM-i 110km version is about 80km (a reduction rate of about 27%), and the actual pure electric range of the Galaxy L7 115km version is about 85km (a reduction rate of about 26%). Although the range has decreased, it can still meet daily commuting needs, and the battery-depleted fuel consumption is not affected by low temperatures, so the overall car usage cost is still low.

Tip: When using in winter, you can preheat the battery through the mobile APP in advance, which can effectively improve the range performance.

5. What are the differences in after-sales service and warranty policies between the two cars?

Answer: The warranty policies of the two cars are basically the same, but there are differences in the coverage of after-sales service networks.

In terms of warranty policies, both BYD and Geely provide "lifetime warranty for the three-electric system" for non-operational vehicles (first owner). Among them, BYD's lifetime warranty has no annual mileage limit – as long as it is the first owner, the three-electric system can be repaired or replaced for free if there is a problem under normal use. Geely's lifetime warranty requires the annual driving mileage to not exceed 30,000km, and the warranty rights and interests will be reduced proportionally if exceeded. In addition, the vehicle warranty of both cars is 4 years or 100,000km (whichever comes first).

In terms of after-sales service network coverage, BYD has a more obvious advantage. BYD has more than 3,000 4S stores and service outlets nationwide, covering first-tier, second-tier, third-tier, and fourth-tier cities, and even some county towns have service outlets, making maintenance and repair more convenient and fast. Geely's after-sales service network is also complete, with more than 2,800 service outlets nationwide, but the density of outlets in some remote areas is slightly lower than that of BYD.

In terms of service quality, according to user reviews on third-party platforms, BYD's after-sales service has a fast response speed and mature maintenance technology. Geely's after-sales service has a good attitude and timely supply of spare parts – the service quality of both is at the upper-middle level in the industry.
