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

1. Power and Energy Consumption: Smooth & Fuel-Efficient vs Dynamic Performance

BYD’s DM-i Super Hybrid system is "electric drive-focused". The 1.5L naturally aspirated engine excels as a "power bank" in urban traffic jams. At low speeds, it’s almost entirely driven by the electric motor, with linear throttle response and no nodding during braking – perfect for elderly passengers or kids prone to motion sickness 😊. With a battery-depleted fuel consumption of just 4.5L/100km, it’s extremely cost-effective for daily commuting. The 75km electric range version covers most daily trips, and occasional long-distance drives won’t trigger range anxiety.

Geely’s Raytheon Hybrid 8848 delivers "full-speed high performance" via its 3-speed DHT Pro transmission. The 1.5T turbocharged engine directly engages in high-speed overtaking, and its 6.9-second 0-100km/h acceleration is 1.4 seconds faster than the Song PLUS DM-i. At highway cruising speeds, the engine runs at lower RPM, resulting in better noise control. Although its battery-depleted fuel consumption is slightly higher at 4.8L/100km, it offers a maximum electric range of 210km and supports 30-minute fast charging. For families who often camp in the suburbs on weekends or need frequent rapid acceleration, it provides more power reserve and a more thrilling driving experience.

2. Design and Interior: Classic & Timeless vs Tech & Trendy

The Song PLUS DM-i’s "Dragon Face" design has won widespread acclaim. Its horizontal grille paired with matrix headlights and smooth body lines exude stability – ideal for family users who prefer traditional aesthetics. The interior features a 12.8-inch rotatable central control screen that switches between horizontal and vertical orientations. The operating logic is simple, allowing elders to master it quickly. However, there are few physical buttons; functions like air conditioning adjustment require on-screen operation, which is slightly inconvenient while driving.

The Galaxy L7’s "Cosmic Galaxy Ripple" design is more futuristic. Its fully enclosed front face with split headlights and 15mm wider body (compared to the Song PLUS DM-i) looks more imposing visually. The interior’s biggest highlight is the triple-screen linkage on mid-to-high configurations: a 10.25-inch instrument cluster, 13.2-inch vertical central control screen, and 16.2-inch passenger entertainment screen. Passengers in the front can watch dramas during long trips, and the AR-HUD head-up display keeps drivers from frequently lowering their gaze. That said, the abundance of screens may overwhelm some users, and the base model lacks the passenger entertainment screen, reducing its tech appeal.

3. Space and Comfort: Family-Friendly Large Space Showdown

While the Song PLUS DM-i is 5mm longer than the Galaxy L7, the latter has a longer wheelbase (2785mm vs 2765mm) and superior width and height. In actual seating experience, the Galaxy L7 offers slightly more rear legroom. Its transverse space comfortably accommodates three adults, and the flat rear floor design provides a comfortable footrest for the middle passenger. Both models have a regular trunk capacity of around 400L; folding the rear seats creates a flat loading space. The Galaxy L7’s trunk has a lower opening, making it easier to lift strollers or heavy items.

In terms of comfort features, mid-to-high configurations of the Galaxy L7 come with a "Queen’s Co-pilot" – equipped with electric leg rests, ventilation, heating, and massage functions for a more comfortable long-distance ride. The Song PLUS DM-i performs better in noise insulation, with multi-layer soundproof glass and body sealing design that effectively reduces tire and wind noise at high speeds – great for families who value a quiet cabin.

4. Smart Technology: Infotainment and ADAS Experience

BYD’s DiLink system, refined over years of iterations, boasts a rich ecosystem with access to numerous apps. Its voice recognition has high accuracy; simply saying "Hello, Xiao Di" controls navigation, air conditioning, and other functions. The downside is its average chip computing power, which may cause occasional lag. Additionally, the lack of a passenger entertainment screen limits the co-pilot’s entertainment options.

The Galaxy L7 is powered by the Qualcomm Snapdragon 8155 chip, ensuring smooth infotainment performance. Its triple-screen interaction logic is clear, and the passenger screen can connect to Bluetooth headsets independently to avoid disturbing the driver. For ADAS, mid-to-high configurations support Level 2 assisted driving, including full-speed ACC adaptive cruise and lane centering – making highway following easier. The Song PLUS DM-i’s ADAS system focuses on basic functions, only supporting standard cruise control and lane departure warning. For new drivers, the Galaxy L7’s ADAS features are more practical.

IV. Frequently Asked Questions (FAQ)

1. What are the differences in battery safety technology between the two models?

Answer: The BYD Song PLUS DM-i is equipped with "Blade Battery", which has passed the needle penetration test. Its battery pack has high structural strength, effectively preventing thermal runaway. The Geely Galaxy L7 adopts the "Aegis Battery Safety System", which has undergone more rigorous tests such as seawater corrosion immersion and three-sided drop impact. The battery pack features internal cross-reinforcement beams for better protection in collisions. Both meet top industry safety standards, so users can choose with confidence.

2. Which model experiences more obvious power degradation when used with a depleted battery for a long time?

Answer: The Song PLUS DM-i’s E-CVT electric drive system has a simple structure. When the battery is depleted, it’s mainly driven by the electric motor, with the engine only generating power. Power output remains smooth, but high-speed acceleration capability may decrease slightly. The Galaxy L7’s 3-speed DHT Pro adjusts engine RPM via the transmission when the battery is depleted, maintaining better power reserve at high speeds with relatively insignificant degradation. In daily use, both models’ battery-depleted power performance meets family needs – no need for excessive worry.

3. How do maintenance costs and repair convenience compare?

Answer: Due to its high market penetration, the Song PLUS DM-i has extensive 4S store coverage. A minor maintenance service costs around 500 RMB, and repair parts are easily accessible. As a new model, the Galaxy L7 has slightly higher maintenance costs (around 600 RMB for minor maintenance), but Geely’s after-sales system is mature, with nationwide service outlets expanding continuously. Both models offer a lifetime warranty for core components (engine, motor, battery) – limited to the first owner. During maintenance, simply follow the manufacturer’s requirements for regular gear oil and coolant replacement.

4. Which infotainment system and mobile phone connectivity work better?

Answer: BYD’s DiLink system excels in ecosystem richness, supporting split-screen operation and numerous apps. Mobile phone connectivity relies on CarLife. The Galaxy L7’s Flyme Auto system offers superior smoothness, with intuitive triple-screen interaction. The passenger screen can cast independently, and mobile connectivity supports wireless CarPlay and Android Auto for easier pairing. Both meet basic needs for navigation and music. For in-car video streaming or gaming, the Galaxy L7’s passenger screen provides a better experience.

5. How does electric range degrade in winter?

Answer: Both models experience some electric range degradation in winter. The Song PLUS DM-i’s 75km version has an actual winter range of approximately 50km, while the 110km version drops to around 70km. The Galaxy L7’s 115km version delivers about 75km of actual winter range, and the 210km version around 130km. It’s recommended to preheat the battery in winter, enable scheduled charging to maintain battery activity, and use HEV mode – the engine will assist in heating, keeping range degradation within an acceptable range ⚠️.
