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

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

The BYD Song PLUS DM-i adopts a 1.5L naturally aspirated engine paired with a single electric motor and E-CVT electric drive. Its power output is primarily electric-drive, with the engine kicking in mostly at medium to high speeds. Its strength lies in smooth and quiet low-speed driving, with a fuel consumption of just 4.5L/100km (NEDC) at low battery in urban congestion – ideal for family users who mainly commute in the city. However, limited by its single-speed structure, acceleration in the high-speed range feels somewhat sluggish, with a top speed of 170km/h.
 
The Geely Galaxy L7 is equipped with a 1.5T turbocharged engine and 3-speed DHT Pro electric drive, delivering a combined system power of 287kW. It achieves "full-speed range direct drive": electric drive ensures smoothness at low speeds, engine direct drive saves fuel at medium speeds, and switching to high gear at high speeds enhances power reserves. It accelerates from 0 to 100km/h in 6.9 seconds with a top speed of 240km/h, making overtaking on highways more confident. Its fuel consumption at low battery is 5.23L/100km (WLTC), slightly higher than the Song PLUS DM-i, but with a larger fuel tank and battery, its combined range reaches 1370km – perfect for families who frequently take long self-driving trips. Notably, the Galaxy L7’s engine has a thermal efficiency (a metric measuring engine fuel conversion efficiency) of 44.26% (compared to 43% for the Song PLUS DM-i), offering better fuel economy during high-speed cruising. ⚠️

2. Design and Interior: Timeless Elegance vs Tech-Forward Styling

The Song PLUS DM-i continues BYD’s "Ocean Aesthetics" design, featuring a dragon-face grille and through-type taillights for a stable and timeless look. It has a slight edge in body length but lags slightly in width and height compared to the Galaxy L7. The interior is equipped with a 12.8-inch rotatable central control screen (supports horizontal and vertical switching) with strong functional practicality, but the screen bezels are relatively wide and there’s no dedicated passenger entertainment screen, giving it an overall family-oriented and pragmatic style.
 
The Galaxy L7 adopts the "Cosmic Galaxy Ripple" design language, with a closed front face and split-type headlights creating a strong sense of technology. Its 1905mm width and 2785mm wheelbase make it visually more spacious. The interior features a triple-screen linkage (13.2-inch 2.5K central screen + 16.2-inch passenger entertainment screen + 10.25-inch instrument cluster), and high-end models are equipped with a 25.6-inch AR HUD that projects navigation information. The passenger "Queen Seat" comes with electric leg rests, heating, and massage functions, while the rear seat padding is firmer for better support during long rides. 👍

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

Both models are positioned as compact SUVs, but there are notable differences in details:
 
  • Lateral Space: The Galaxy L7 is 15mm wider, providing more shoulder room when three people sit side by side in the back.
  • Legroom: With a 20mm longer wheelbase, the Galaxy L7 offers approximately 3 fists of legroom for 1.8m tall passengers in the rear, compared to around 2.5 fists in the Song PLUS DM-i.
  • Trunk: The Song PLUS DM-i has a standard capacity of 574L, with stronger expandability when the rear seats are folded down. The Galaxy L7 has a slightly smaller standard capacity but a flat floor, and its rear seats support 40/60 split folding – both offer practicality in their own ways.
 
In terms of comfort features, the Galaxy L7 Explore Edition (125,800 RMB) comes standard with front seat heating/ventilation and 50W wireless fast charging, while the Song PLUS DM-i at the same price only offers electric adjustment for the driver’s seat and manual adjustment for the passenger seat. For noise insulation, the Song PLUS DM-i optimizes NVH with multi-layer soundproof glass, while the Galaxy L7 relies on its streamlined body design to reduce wind noise, though tire noise is slightly more noticeable at high speeds.

4. Smart Technology: Infotainment and ADAS Experience

The Song PLUS DM-i is equipped with the DiLink system. Its 12.8-inch rotatable screen supports a large number of Android apps, and voice interaction responds quickly. However, it uses a Snapdragon 690 chip, which may occasionally lag during complex operations. It lacks a dedicated passenger entertainment screen, and the infotainment ecosystem is oriented towards "single-screen independence." For ADAS, L2-level assisted driving (including automatic parking) comes as standard across the range, but highway navigation functions require optional installation.
 
The Galaxy L7 comes standard with a Qualcomm 8155 chip, and its Galaxy NOS system offers leading smoothness. The triple screens support linkage functions such as shared navigation information and passenger screen casting for watching dramas. The AR HUD can display key information like vehicle speed and navigation arrows, reducing the need for drivers to shift their gaze. High-end models offer L2+-level assisted driving (including lane centering and adaptive cruise control), but entry-level models only have basic functions. For young families sensitive to tech features, the Galaxy L7’s multi-screen interaction experience is more appealing.

III. Buying Guide: Telling You Exactly What to Choose

For child safety, both models are equipped with ISOFIX interfaces, but the Galaxy L7 has a completely flat rear floor (the Song PLUS DM-i has a slight bulge in the middle), making it more comfortable for the middle passenger after installing a child safety seat.

4. Which has a better infotainment system and voice interaction?

Answer: The Galaxy L7’s Qualcomm 8155 chip + Flyme Auto system delivers faster response speeds (0.5-second voice wake-up), supporting continuous dialogue and multi-zone voice recognition. The triple screens can share navigation information and enable passenger screen casting without mutual interference. The AR HUD displays key information like vehicle speed and navigation arrows, reducing driver distraction. The Song PLUS DM-i’s DiLink system has a richer ecosystem (supporting apps like Douyin and WeChat for vehicles), but its rotatable screen feature has limited practicality while driving, and voice interaction only supports driver-side wake-up. Choose the Galaxy L7 for smoothness and multi-screen collaboration, and the Song PLUS DM-i if app variety matters more.

5. Which offers better maintenance costs and residual value?

Answer: For maintenance, both models require regular oil and filter changes. A minor service for the Song PLUS DM-i costs around 500 RMB, while the Galaxy L7 costs approximately 600 RMB (slightly higher due to its turbocharged engine). In terms of residual value, BYD has higher recognition in the new energy sector – the Song PLUS DM-i retains about 65% of its value after three years. As a new model, the Galaxy L7 has no long-term residual value data, but based on other Geely models, it’s expected to be 5%-8% lower.
