When your family-car budget is around 150,000 RMB and you want a plug-in hybrid SUV that is both fuel-efficient and powerful, you will most likely struggle between BYD Song PLUS DM-i and Geely Galaxy L7. These two models are among the most popular PHEVs on the market, and they differ in technology, fuel consumption, space, and driving experience.

This guide takes a neutral, family-user perspective, helping you make a clear and confident decision.

I. Quick Overview: Key Differences at a Glance

II. In-Depth Comparison: Which Car Understands Family Needs Better?

1. Power & Efficiency: Smooth & Efficient vs. Energetic & Performance-Oriented

• Song PLUS DM-i
  The DM-i system focuses on EV-dominant driving. Even when the battery is low, fuel consumption stays low. Official data shows 4.5 L/100km under NEDC testing. Acceleration is around 7.9 seconds (0–100 km/h), adequate for daily use.
  This model fits users who prioritize fuel economy, smoothness, and predictable daily commuting.

• Galaxy L7
  Galaxy L7 emphasizes performance. The 3-speed DHT hybrid delivers stronger acceleration, achieving 6.9 seconds in performance trim.
  However, low-battery fuel consumption is slightly higher at 5.23 L/100km.
  A great option for families who enjoy spirited driving, frequent highway travel, or simply want more power.

2. Design & Interior: Conservative & Practical vs. Tech-Forward & Futuristic

• Song PLUS DM-i
  Features a stable, neutral SUV aesthetic. The cabin layout is practical and familiar, with functional design cues and select versions offering a rotating center display.

  Delivers a stronger visual punch with its three-screen cockpit (gauge cluster + center screen + co-pilot entertainment display) and Qualcomm 8155 chip.
  Ideal for younger families or users who value immersive digital experiences.

3. Space & Comfort: Practical Family Utility vs. More Rear Legroom & Comfort

• Song PLUS DM-i
  Wheelbase of 2,765 mm offers solid family practicality. Cargo capacity is generous, making daily use and travel flexible.

  Slightly longer wheelbase (2,785 mm) provides more rear legroom. Geely advertises features like “cotton-candy comfort seats” and larger co-pilot space, making it more comfortable for passengers on long trips.

4. Intelligent Tech: Stability & Maturity vs. Advanced Smart Cabin Experience

• Song PLUS DM-i
  Equipped with BYD’s DiLink and DiPilot systems (depending on trim). Stable, practical, and reliable. Not as flashy but effective.

  Offers one of the strongest digital experiences in its class, with N-OS, smart cockpit features, and optional NOA intelligent driving assistance, backed by satellite-level positioning and extensive sensors.
  Great for users who enjoy technology, smart features, and future OTA upgrades.

IV. FAQ: Top 5 Questions from Real Buyers

1. Which car has a lower real-world cost for city commuting?

If you commute 40 km/day with home charging:

• Song PLUS DM-i: ~378 RMB/month fuel cost (low-battery scenario). With regular charging, cost can be even lower.

• Galaxy L7: ~441 RMB/month (low-battery scenario). Similar to Song PLUS if driven mostly in pure EV mode.

Song PLUS has an edge if you frequently run low on battery.

2. How do their battery safety systems differ?

• Song PLUS DM-i uses BYD’s well-known Blade Battery (LFP), celebrated for high thermal stability.

• Galaxy L7 features Geely’s “Aegis Battery Safety System”, a structural safety approach with a reinforced frame and multipoint protection.

Both offer strong safety, but BYD’s LFP chemistry is proven in extreme thermal tests.

3. Which car performs better on highways or long-distance travel?

• Song PLUS DM-i: Some users report that at sustained highway speeds, the engine may struggle to maintain battery SOC, reducing peak power.

• Galaxy L7: The 3-speed DHT is optimized for high-speed efficiency, making it more stable for long-distance travel.

For frequent highway driving, Galaxy L7 is the better choice.

4. Which one has lower maintenance costs?

• Song PLUS: Benefit of BYD’s massive service network and stable parts prices.

• Galaxy L7: Routine maintenance is similar, but the more complex DHT gearbox may cost slightly more if repairs are needed.

Overall, maintenance costs are comparable, but BYD offers broader support coverage.

5. Which car depreciates more slowly?

• Song PLUS DM-i: Large market base + proven system → more stable resale value.

• Galaxy L7: Newer technology with strong potential, but long-term resale still developing.

If resale value is a priority, Song PLUS is the safer choice.
