2. Deep Dive: Which One Better Understands Families?
1. Power & Efficiency: Smooth & Frugal vs. Exciting Performance
BYD's DM-i system has evolved to its fifth generation. It pairs a 1.5L naturally aspirated engine with a single-speed E-CVT (a continuously variable transmission dedicated for hybrid use). The working principle is simple and direct—electric in the city, gas on the highway, with the engine either generating power or driving the wheels directly 🚗. The 2025 model's motor power is boosted to 160kW, shaving its 0-100 km/h sprint to 7.7 seconds, nearly a second quicker than before. Most crucially, fuel consumption with a depleted battery drops to 3.9L/100km, a figure lower than many A0-class city cars.
Galaxy L7 takes a completely different technical route. The Thor 8848 system squeezes in a 1.5T turbocharged engine, paired with a 3-speed DHT (Dedicated Hybrid Transmission). The engine can directly drive the wheels across a broader speed range. The 3-speed structure means more gear ratio options; at medium-to-high speeds, the engine runs at lower RPM with less noise. The paper specs are impressive: 0-100 km/h in 6.9 seconds, top speed 240 km/h, giving abundant confidence for highway overtaking ⚡.
For urban commuting, DM-i's single-speed architecture is simpler and delivers flawless smoothness. Galaxy L7's 3-speed DHT occasionally shows slight shift shock at low speed, but mid-to-high range acceleration is genuinely fierce. Family buyers need to do the math: How many highway trips per year? If 90% is city driving, DM-i's 3.9L fuel consumption is more appealing; but if frequent long-distance travel is the norm, Galaxy L7's highway efficiency and power reserves are more practical.
2. Design & Interior: Timelessly Classic vs. Futuristic Tech
Song PLUS DM-i continues BYD's "Ocean Aesthetics" design. The front fascia resembles unfolding waves, with flowing lines that aren't aggressive. The 2025 model's taillights now feature a luminous "BYD" logo. The overall style is stable and grounded—timeless and unlikely to look dated in five years, with higher acceptance in the used car market. The interior layout is conventional but practical. The 12.8-inch screen rotates between portrait and landscape. The DiLink system is feature-complete, though the Snapdragon 665 chip (a mid-range automotive-grade processor) feels slightly sluggish in fluidity.
Galaxy L7 looks like it drove straight out of a sci-fi movie. The closed front grille with split headlights, arrow-feather taillights with a large spoiler, and a 2785mm wheelbase (20mm longer than Song PLUS) give it a wider, lower, and sportier stance. Inside, three large screens (10.25-inch cluster + 13.2-inch center + 16.2-inch passenger display) plus a 25.6-inch AR-HUD create a visual explosion 💥. The Qualcomm 8155 chip (a flagship automotive-grade processor) enables seamless four-screen interaction. The passenger screen allows independent video watching or navigation setup, with content that can be pushed to the main screen without interference.
Aesthetics are subjective. If elderly family members have the final say, they'll likely pick Song PLUS; if young people call the shots, Galaxy L7's tech vibe is more attractive. However, note that more screens mean more potential failure points, and repair costs must be factored in.
3. Space & Comfort: Battle of Family-Friendly Interiors
Song PLUS DM-i measures 4765×1890×1670mm, with a 2765mm wheelbase. Rear legroom is over two fists; seat cushioning is soft like a large sofa; the floor is flat, so three passengers won't feel cramped. The trunk volume is generous, and seats fold flat for large items. The 2025 model retains practical features like V2L discharge, panoramic sunroof, and power tailgate, delivering a "has it all" balance.
Galaxy L7 is 4710×1905×1685mm, with a 2785mm wheelbase. Though slightly shorter in length, the longer wheelbase translates to three fists of rear legroom and better lateral width. Seats feature ergonomic design with better support. The "Queen Passenger Seat" includes leg rest adjustment, heating, and massage functions; the 16.2-inch entertainment screen makes long trips enjoyable 😊. The chassis, based on Volvo's CMA platform, uses a rear four-link independent suspension (a setup with four control arms for wheel positioning) with aluminum components, delivering finer bump absorption and less body roll in corners.
Moose test results are telling: Galaxy L7 can hit 76 km/h, while Song PLUS DM-i manages 65 km/h. In emergency maneuvers, Galaxy L7 is more stable, but Song PLUS's soft suspension is more comfortable daily. Families must weigh priorities: frequent high-speed travel with full loads, or mainly city commuting?
4. Smart Tech: Infotainment & ADAS Experience
Galaxy L7's smart cockpit is generationally ahead. The 8155 chip offers three times the computing power of the 665, with 0.5-second voice wake-up, four-zone recognition, and continuous dialogue. Seamless app streaming across three screens lets passengers set navigation and push it to the driver. The AR-HUD projects navigation onto the windshield, so the driver never looks down. Its L2 ADAS includes NOA highway pilot for automatic on/off-ramp navigation, making long drives much easier.
Song PLUS DM-i's DiLink 5.0 system isn't short on features or ecosystem apps, but the 665 chip's performance bottleneck is evident. The rotating screen is a signature feature, but its practical use is limited and adds mechanical failure risk. ADAS features are relatively conservative—basic L2 is adequate but not amazing. However, BYD's OTA update frequency is high, ensuring continuous improvement, which deserves credit 👍.
Simply put, tech enthusiasts should blindly choose Galaxy L7. For stability and reliability without wanting to be a guinea pig, Song PLUS DM-i's mature solution is more reassuring.

3. Which is more fuel-efficient at highway cruising speeds? Does the 3-speed DHT really work?
The 3-speed DHT works like a mountain bike's gear system. At 80 km/h, it uses a low gear—engine RPM high but torque abundant; at 120 km/h, it shifts to high gear—engine RPM drops for fuel savings and quietness. Galaxy L7's engine runs about 500 RPM lower than Song PLUS at 120 km/h cruise, with 3 dB less noise. Real-world highway fuel consumption: Galaxy L7 around 6.5L/100km, Song PLUS around 6.8L/100km. The gap is small but the experience differs. Song PLUS's single-speed design runs the engine at higher RPM on highways, making it noticeably louder. Conclusion: For frequent highway travel, Galaxy L7 is more comfortable and efficient; for city-focused use, Song PLUS's 3.9L consumption is unbeatable
.
4. Which is cheaper to maintain long-term? Is the 3-speed DHT prone to failure?
Maintenance costs have two dimensions: parts prices and labor rates. Song PLUS DM-i service interval: 7,500 km, minor service ~400 yuan, major service ~800 yuan. Simple structure, nationwide service network, cheap labor. Galaxy L7 service interval: 10,000 km, minor service ~500 yuan, major service ~1,000 yuan. The 3-speed DHT is complex, but Geely offers lifetime warranty on the transmission to ease concerns. For reliability, DM-i system's failure rate is 0.03%; Galaxy L7 hasn't been on market long enough for data, but the CMA platform has proven reliable on Lynk & Co models. Advice: Choose Song PLUS if you hate hassle; choose Galaxy L7 if you trust technological progress
.
5. How much do their used car residual values differ?
Sales volume determines residual value. Song PLUS DM-i's 3-year residual rate is ~55-58%, 5-year ~45%. Galaxy L7 has only been on market for just over a year, with limited used inventory, estimated 3-year residual ~50-53%. The sales gap directly affects used car liquidity—Song PLUS is easier to sell with more transparent pricing. Galaxy L7's 8155 chip and 3-speed DHT are advanced, but whether used car buyers value these new technologies is uncertain. Advice: If you plan to trade in within 3-5 years, Song PLUS holds value better; if keeping for ten years, the gap is negligible
