What are the differences between the BYD Song PLUS DM-i and the Song L DM-i?

In the new energy hybrid SUV market, the BYD Song PLUS DM-i and the Song L DM-i are both highly competitive options. As representatives of BYD’s fifth-generation DM hybrid technology, they share the same advanced powertrain yet showcase distinct advantages in design, interior, space, and safety. Let’s dive into a multi-angle comparison to see which model better fits your driving needs.
 

Exterior Design

 
The Song PLUS DM-i continues BYD’s “Ocean Aesthetics” design, featuring a smooth and elegant body with strong recognition. The new 19-inch low-drag alloy wheels, illuminated rear logo, and refined headlight details add a touch of sophistication and style, perfectly catering to young buyers.
 
In contrast, the Song L DM-i adopts the Dynasty Series “Dragon Face” design language. Its front is bold and elegant, with slim headlights connected by a silver trim, paired with a dot-matrix grille and side air intakes, giving it a premium look. The sleek waistline, flared wheel arches, hidden door handles, and privacy glass enhance its sporty and mysterious appeal. At the rear, the through-type light bar with a “Chinese knot” design and illuminated BYD emblem, together with a dual-section spoiler, make it more dynamic and unique.
   

Interior & Technology

The Song PLUS DM-i carries the Ocean Network’s family-style interior with a refined, tech-driven atmosphere. It comes with a flat-bottom steering wheel, a 12.3-inch digital instrument cluster, and an electronic gear selector. Depending on the version, it features either a 12.8-inch adaptive floating screen (75km/112km) or a 15.6-inch display (160km) with 5G connectivity and smart voice interaction for an advanced in-car experience.
 
The Song L DM-i interior resembles the Qin L DM-i with a simpler yet premium style. It has a 10.25-inch instrument cluster, a 12.8-inch floating screen for the 112km version, and a 15.6-inch screen for the 160km version. The use of high-gloss trim and full plastic-sealed panels on the doors enhances luxury and technology, giving the cabin a more upscale vibe.
 

Dimensions & Space

The Song PLUS DM-i measures 4775×1890×1670mm with a wheelbase of 2765mm, offering generous space for family use. Its 574L trunk capacity is practical but may fall short for some large cargo needs.
 
The Song L DM-i is slightly larger at 4780×1898×1670mm with a 2782mm wheelbase, providing more legroom in the rear and greater comfort. Its trunk measures 459L, smaller on paper than the Song PLUS, but with better space utilization for versatile storage.
   

Platform & Performance

The 2025 Song PLUS DM-i continues on its proven platform, delivering stability and reliability verified by years of market experience. However, it is slightly conservative in adopting new technologies.
 
The Song L DM-i is built on BYD’s new P5 hybrid platform, featuring a flatter chassis layout for better aerodynamics and fuel efficiency. With stronger body rigidity, it offers more solid handling. Notably, it comes with dual-piston front brake calipers for safer and more stable braking compared to the PLUS’s single-piston design.
 

Safety

The Song PLUS DM-i is equipped with 6 airbags across all trims, plus intelligent safety features like rear collision warning, lane change assist, and door opening warning (DOW) on higher versions.

The Song L DM-i is designed to meet the latest C-NCAP 5-star standard, with 75.7% high-strength steel, W-shaped side impact beams, reinforced panels, and 7 airbags (including a front center airbag). The dual-piston front brakes further enhance safety.
 

Conclusion

If you value luxury, more spacious rear seating, and advanced safety, the Song L DM-i is the better choice. But if you prefer the Ocean Aesthetics design and want a well-rounded, market-proven model, the 2025 Song PLUS DM-i remains a safe and excellent pick.
