On May 28, the B-segment plug-in hybrid SUV BYD Song Ultra DM-i was officially launched, with a total of 5 models, including two pure electric range versions of 205 km and 310 km, priced at 129,900–159,900 yuan.
The new car has a CLTC pure electric range of 310 km, allowing mid-size plug-in hybrid SUVs to also enjoy pure electric travel freedom. It is equipped with fifth-generation DM technology, with NEDC fuel consumption as low as 3.3L per 100 km when the battery is depleted, and a combined range of 1,845 km with a full tank and full charge. It offers the optional God's Eye B assisted driving laser version, and with this option, customers can enjoy one year of urban navigation backstop.
With ultimate relaxation as its core proposition, the Song Ultra DM-i, through four core experiences of "safety, rapport, comfort, and freedom," becomes the Dynasty series' benchmark answer to "bringing good technology to millions of families," and leads plug-in hybrid SUVs with 310 km of pure electric range into the 130,000-yuan class, redefining the value standard for B-segment plug-in hybrid SUVs.
Safety: God's Eye B assisted driving laser version, offering both urban navigation & smart parking backstop
Morning rush hour congestion, complex road conditions, and tired driving after late-night overtime create major safety hazards, making this a "stress test" for every commuter. The God's Eye B assisted driving laser version equipped in the Song Ultra DM-i acts as an "onboard veteran driver," with good driving skills and familiar routes, helping share the driving pressure for users.
More importantly, after pioneering smart parking safety backstop last year, BYD officially launched its urban navigation safety backstop policy: within one year from now, new users of God's Eye B can enjoy one year of urban navigation backstop starting from the date of vehicle delivery. At the same time, within one year from now, existing God's Eye B owners who upgrade via OTA to God's Eye 5.0 will enjoy the same backstop. It can be said that with an industry-first responsibility commitment, BYD makes cutting-edge technology a source of safety confidence for millions of families.
Rapport: Dynasty's first super intelligent agent "Didi Xia," understanding you like "family"
The Song Ultra DM-i is the first BYD Dynasty model equipped with the super intelligent agent "Didi Xia," completely freeing the infotainment system from "passive response" and achieving "proactively understanding you and seamless interaction." It proactively greets you when you get in, responds precisely to daily commands, and handles finding food or booking tickets in one sentence; it supports fuzzy search and playback, intelligently finding and playing TV dramas or songs whose names you cannot remember.
With zero learning cost and adaptability for all ages, it truly achieves "technology adapting to people, rather than people adapting to technology." In addition, Song Ultra EV owners can unlock "Didi Xia" simultaneously through an OTA upgrade, also gaining this "family member" who understands you.
Comfort: B-segment large five-seat space, large luxury bed mode, queen passenger seat, and other segment-leading experiences
For family travel, space is crucial. The Song Ultra DM-i is positioned as a B-segment SUV, with a wheelbase of 2,840 mm, and rear legroom larger than that of same-class luxury brand SUVs. Moreover, the space is flexible and versatile. The front seats can be folded down with one touch and connected to the second row, instantly turning into a mobile large bed for a relaxed midday rest. With the rear seats folded down, plus the extra-large trunk, it instantly becomes a large bedroom, allowing the whole family to camp and sleep comfortably overnight. The segment-leading queen passenger seat features massage, ventilation, heating, and an electric leg rest, so long trips are not tiring.
Freedom: 310 km pure electric range, 1,845 km combined range with full tank and full charge, plug-in hybrids can also enjoy pure electric freedom
The Song Ultra DM-i has a CLTC pure electric range of up to 310 km, requiring charging only once every two weeks for daily commuting and once a week for weekend outings, truly enabling pure electric freedom for B-segment plug-in hybrid SUVs. Equipped with fifth-generation DM technology, its NEDC fuel consumption is as low as 3.3L per 100 km when the battery is depleted, and its combined range with a full tank and full charge is 1,845 km. For long trips, there is no need to calculate distance or worry about range; with one press of the accelerator, you can go wherever you want, easily enjoying a sense of freedom.
