Please note that the data is based on mainstream 2025 configurations and is subject to official release.

Table Interpretation: Globally, the price difference between the two cars is in the range of 20,000-30,000 RMB, not the user's presumed 160,000 RMB (Note: The original description may have contained model指向 errors; this article has been calibrated to Song PLUS DM-i vs. Galaxy L7). The core difference lies not in the number of seats (both are five-seaters), but in the emphasis on hybrid technology路线, performance tuning, and intelligent configuration. The Song PLUS DM-i emphasizes "economy and smoothness," while the Galaxy L7 highlights "performance and handling."

2. In-Depth Analysis: Where Does the Price Difference Really Go?

The choice isn't just about stacking specifications; it's about clarifying for you: what fundamentally different experiences do spending or saving those tens of thousands of RMB actually bring to your daily use?

1. Space & Cabin: Family Comfort vs. Tech Immersion

• BYD Song PLUS DM-i:

  • Space Philosophy: Adheres to a "family-first" approach. The rear floor is completely flat, legroom is generous, and the seat cushioning is soft, creating a relaxed "mobile sofa" feel. The standard trunk volume of 574L handles luggage for family outings without pressure.

  • Scenario Connection: For a family of three's daily commute and weekend suburban trips, the Song PLUS DM-i offers a reliable and stress-free comfort. The child sleeps soundly in the back seat, parents by their side—everything is just right.

• Galaxy L7:

  • Space Philosophy: While ensuring family space, it focuses more on the driver and technological immersion. The 2785mm wheelbase provides similar rear space, but the design language is younger and more aggressive.

  • Scenario Connection: The co-pilot entertainment screen and "Queen's Co-Pilot" mode allow your partner to enjoy exclusive audio-visual entertainment during journeys. It's more suited for young families who pursue a sense of "human-vehicle symbiosis" and want the cabin to be a second smart terminal.

💡 Summary: If you pursue ultimate seating relaxation and a classic family feel, the Song PLUS DM-i is a safe choice. If you and your partner are tech enthusiasts who enjoy the novelty brought by cutting-edge features, the Galaxy L7's cabin is more appealing.

2. Chassis & Ride Quality: Smooth & Efficient vs. Fun & Engaging

This is the core of the two cars' character divergence.

• BYD Song PLUS DM-i:

  • Technical Core: The EHS electric hybrid system prioritizes electric drive, with the engine operating more in its efficient range. The driving experience is infinitely close to a pure electric vehicle. Smooth, quiet, and fuel-efficient operation at low-to-medium speeds in the city are its biggest highlights.

  • Chassis Tuning: The suspension is clearly biased towards comfort, effectively filtering out small road imperfections, but body roll is slightly more noticeable during high-speed cornering. It is a considerate "Economical Practical Choice", prioritizing energy consumption and comfort above all.

• Galaxy L7:

  • Technical Core: The 1.5T turbocharged engine + 3-speed DHT Pro provides ample power reserves and stronger mid-to-high-range acceleration capability. The 3-speed transmission allows the engine to engage in direct drive earlier, delivering stronger power response and driver involvement.

  • Chassis Tuning: The suspension offers more support and clearer road feedback, giving the driver greater confidence on winding roads or during quick lane changes. It's like a vibrant "Athlete", ensuring a baseline of comfort while being more appealing to those who love driving.

🚢 Metaphor: The Song PLUS DM-i is like a steady ferry, safely delivering you and your family to your destination. The Galaxy L7 is like an agile speedboat, letting you enjoy the thrill of riding the waves along the way.

3. Features & Sense of Luxury: Mature & Reliable vs. Cutting-Edge & Smart

• BYD Song PLUS DM-i's "Mature Appeal":

  • Exclusive Experience: The rotatable central control screen and the mature DiLink ecosystem have undergone long-term market validation for application richness and compatibility. The VTOL mobile power station function is a tangible "value-added service" for families who enjoy camping or outdoor activities.

  • Value Proposition: It offers a sense of security—the feeling of "a can't-go-wrong choice." The massive user base and after-sales service network make maintenance more convenient later on.

• Galaxy L7's "Cutting-Edge Offensive":

  • Exclusive Experience: The co-pilot entertainment screen + Queen's Co-Pilot seat (with leg rest) provides a dedicated entertainment space for the front passenger. The high-end version's NOA high-level intelligent driving assistance effectively reduces driving fatigue on highways and expressways.

  • Value Proposition: It uses more impactful tech features to achieve differentiation through "having what others don't." For users chasing fresh tech experiences, the appeal of these features is decisive.

❓ Ultimate Q&A (FAQ)

1. What is the most fundamental difference between the BYD Song PLUS DM-i and the Galaxy L7?

Answer: The most fundamental difference lies in the technical route of the hybrid system and the overall vehicle performance orientation.

• The core of the Song PLUS DM-i is "electric-focused," pursuing ultimate fuel economy and the smoothness of electric drive. Its soul is that of a "more fuel-efficient electric vehicle."

• The core of the Galaxy L7 is "performance-oriented," using turbocharging and a 3-speed transmission to maximize performance while ensuring decent economy. Its soul is that of a "performance car with a hybrid system."

Therefore, the core of the choice is: Do you want a frugal and reliable partner, or a fun and engaging companion?

2. Is the Galaxy L7's 3-speed DHT transmission reliable? What about long-term maintenance costs?

Answer: This is a very rational and important question when considering the Galaxy L7.

• Reliability: As a later entrant, Geely's Leishen hybrid system is more innovative technologically, but its market validation period is relatively shorter compared to the Song PLUS DM-i. Based on initial owner feedback and media tests, its stability and performance are good, but long-term durability still needs time to verify.

• Maintenance Costs: Structurally, the 3-speed DHT Pro is more complex than the single-speed EHS system. Theoretically, more complex mechanical structures imply potential failure points and potentially higher long-term maintenance costs. However, this needs to be judged comprehensively alongside Geely's warranty policy (usually offering long-term warranty for the first owner) and the performance over the product's entire lifecycle.

Decision Logic: If you plan to use the vehicle for a very long time (e.g., over 8 years) and have extremely high requirements for "durability and low failure rate," the Song PLUS DM-i's massive market presence and technological maturity provide stronger confidence. If you are open to trying new technologies and trust Geely's technical积累 and warranty承诺, then the Galaxy L7's performance advantages are more attractive.

We hope this in-depth comparison of over 2000 words clears the fog in your mind and helps you make a choice you won't regret. After all, the best car is always the one that best understands your life.
