Ultimate Showdown of 150,000 RMB Hybrid SUVs: BYD Song PLUS DM-i vs. Galaxy L7 – How to Choose?

With a budget of around 150,000 RMB, looking to buy a plug-in hybrid SUV that is both fuel-efficient and practical, should you choose the market benchmark BYD Song PLUS DM-i or the rising star Geely Galaxy L7? This is a dilemma many family car buyers face. Both models emphasize "fuel efficiency and good driving," but they follow completely different technical routes and product orientations. Today, from the perspective of an ordinary family user, we will conduct a comprehensive in-depth comparison from core dimensions such as power, energy consumption, space, and intelligence to thoroughly resolve your indecisiveness.

1. Quick Overview: Core Differences at a Glance

2. In-Depth Comparison: Who Understands Family Users Better?

1. Power & Energy Consumption: Smooth & Efficient vs. Passion & Performance

The core advantage of the BYD Song PLUS DM-i lies in its ultimate smoothness and fuel efficiency. Its DM-i system primarily relies on a high-power electric motor for drive, with the engine acting more as an "efficient generator." During city commuting, over 80% of conditions can be driven purely by electricity, offering a driving experience infinitely close to an electric vehicle.

The thermal efficiency (an indicator measuring engine fuel conversion efficiency) of this system is as high as 43.04%. Even when the battery is low, it can maintain a low fuel consumption of 4.5L/100km. For users commuting less than 50km daily, if charging is convenient, it can basically be used as a pure electric vehicle, resulting in very low usage costs 😊.

The Geely Galaxy L7, on the other hand, uses a more complex 3-speed DHT Pro transmission structure. Simply put, it allows the engine to engage in driving earlier, optimizing performance across the entire speed range. The 0-100 km/h acceleration time of 6.9 seconds is significantly better than the Song PLUS's 8.3 seconds, making overtaking and lane changing more confident.

However, in terms of smoothness, the 3-speed structure can exhibit slight gearshift sensations under specific conditions (like hard acceleration), not as silky smooth as the Song PLUS DM-i. Fuel consumption is slightly higher than the Song PLUS, but the 4.8L/100km figure is still excellent.

2. Design & Interior: Classic & Durable vs. Tech & Trendy

The Song PLUS DM-i adopts BYD's family "Dragon Face" design, with a majestic and steady appearance that appeals to the masses. The interior layout is tidy, with solid workmanship and materials. The rotatable 12.8-inch central screen is a signature feature.

This design style has high acceptance but lacks freshness. The interior storage space is abundant, and the button layout conforms to traditional usage habits, allowing elders to adapt quickly 👍.

The Galaxy L7 has a more futuristic exterior, with a closed front grille and split-type headlights creating a technological feel unique to new energy vehicles. The most attractive part of the interior is the passenger entertainment screen, which, combined with the "Queen Passenger Seat" (available in some trims), provides an excellent entertainment experience for family members.

The interior uses plenty of soft-touch materials, but the fit and finish in some details are slightly inferior to the Song PLUS. The overall ambiance is younger and more suitable for families seeking a fresh feel.

3. Space & Comfort: Showdown of Family Space

Both cars have a wheelbase exceeding 2.7 meters, offering very spacious rear seats. Measured rear legroom is over two fists in both, allowing easy installation of child safety seats and meeting the needs of family trips.

The Song PLUS has a longer body, with a trunk capacity of 574L, easily accommodating strollers and luggage. The rear seats fold down almost flat, making it very practical.

The Galaxy L7 has a slightly longer wheelbase and more generous headroom. The seat cushioning is softer, providing slightly better comfort on long journeys. However, the trunk capacity is 480L, smaller than the Song PLUS, but still sufficient for daily family use.

Both cars have good sound insulation, with decent tire noise control at high speeds. The Galaxy L7's chassis tuning is sportier, with clearer road feedback; the Song PLUS is completely comfort-oriented, with more thorough vibration filtering.

4. Smart Tech: Infotainment & Smart Driving Experience

The Song PLUS DM-i is equipped with the DiLink intelligent system, and the rotatable central screen is its characteristic. The system responds smoothly, has a rich application ecosystem, and supports a large number of Android apps. However, it is relatively conservative in smart driving, focusing on basic ACC adaptive cruise control and lane keeping.

The system operation logic is simple and intuitive, allowing even elders to get started quickly. OTA update frequency is high, continuously optimizing the user experience 😊.

The Galaxy L7 uses the Galaxy NOS system, and the triple-screen linkage (instrument cluster, central control, passenger) is the biggest highlight. The Qualcomm 8155 chip ensures system smoothness. The passenger screen supports independent audio and video entertainment, enhancing travel fun.

It offers richer optional smart driving packages, including advanced functions like automatic lane changing assistance. However, operating multiple screens requires a certain learning curve, and users not sensitive to technology may need time to adapt.

4. Frequently Asked Questions (FAQ)

1. Who has lower usage costs for city driving?

A: According to official data, the Song PLUS DM-i consumes 4.5L/100km when the battery is low, and the Galaxy L7 consumes 4.8L/100km. Assuming gasoline (92#) costs 8 RMB/L and annual mileage is 15,000 km, the Song PLUS can save about 360 RMB in fuel costs per year. If charging is convenient, the cost of pure electric commuting is even lower. Calculating based on a home charging cost of 0.6 RMB/kWh, fully charging the Song PLUS 110km version costs about 10 RMB, costing less than 0.1 RMB per kilometer, far lower than gasoline vehicles.

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

A: BYD uses "Blade Battery" (LFP material, more stable structure), which has passed the nail penetration test, posing a low thermal runaway risk. Geely is equipped with the "Godshield Battery Safety System," which has also passed multiple rigorous tests, including seawater immersion and drop tests. According to China Automotive Technology and Research Center test results, both battery packs performed excellently; family users need not worry excessively about safety issues 👍.

3. Which car has cheaper maintenance costs in the long run?

A: Based on owner feedback and 4S store research, the Song PLUS DM-i maintenance cycle is every 5000 km in HEV mode or one year, with minor maintenance costing about 300-400 RMB. The Galaxy L7 maintenance cycle is every 7500 km or one year, with minor maintenance costing about 400-500 RMB. Overall, the maintenance costs of the two are similar, both saving about 30%-40% compared to traditional fuel vehicles.
