On March 5th, BYD officially launched its first B-segment pure electric SUV, the Song Ultra EV, with a pre-sale price starting at RMB 155,000. It will be available at the end of March. With three core breakthroughs—"space revolution + intelligent driving accessibility + charging freedom"—it redefines the value benchmark for RMB 200,000-level family electric SUVs. It doesn't rely on piling up specifications, but rather on a solution that precisely addresses the pain points of Chinese families, making its "large five-seater" a true "mobile living room for the whole family."

Note: All models come standard with a "Double Bed Mode"—when the front and rear seats are fully folded down, a flat 1.8m x 1.4m space is created, accommodating two people lying down. Camping, naps, and emergency rest can be switched with a single button.
3.1 "Double Bed Mode": Turning an SUV into a Mobile Bedroom
Real-world scenario: Take your kids out for a weekend trip; at midday, recline the seats in the parking lot of a scenic spot for your child to take a nap.
Detailed design: The seat backs can be laid flat 180°, the headrests are adjustable, and with ambient lighting and a car refrigerator (optional), the camping experience rivals that of a motorhome.
Industry-Unique: The only pure electric SUV in its class to factory-support a "double bed" function, eliminating modification risks and offering full warranty coverage.
3.2 "God's Eye" B Intelligent Driving: LiDAR is not just for show
Hardware Configuration: Standard roof-mounted dual LiDAR + 8 cameras + 12 ultrasonic radars; optional extras available on higher-spec versions.
Functional Testing:
Automatic traffic light recognition, pedestrian yielding, and unprotected left turns on urban roads;
Automatic lane changing, overtaking, and ramp entry/exit on highways;
Automatic parking in all scenarios, with a success rate exceeding 98% for parallel, perpendicular, and angled parking.
Computing Power Support: Equipped with a single Orin-X chip, peak computing power of 254 TOPS, and a response speed 0.3 seconds faster than Tesla's FSD.
3.3 Yunlian-C Intelligent Suspension: "Smooth as a ride" even on bumpy roads
Technical Principle: Front MacPherson strut + rear five-link independent suspension, paired with an intelligent damping adjustment system that senses road surface changes 1000 times per second.
Actual Experience:
Crossing over a washboard overpass, the vehicle exhibits almost no swaying;
Excellent body roll control during high-speed cornering, preventing motion sickness for passengers;
Supports one-button switching between "Comfort," "Standard," and "Sport" modes.
Exterior: Continuing the "Dragon Face Aesthetics," the closed front grille and continuous light strip, along with the "Chinese knot" shaped taillights, offer high recognizability. Available in matte dark green and twilight purple, exuding understated sophistication.
Interior:
Floating dual-screen setup (15.6-inch central control + 10.25-inch instrument panel) + two-spoke steering wheel, offering a technologically advanced yet understated feel;
Dual 50W wireless charging: Simultaneous fast charging for two phones in the front row, eliminating the need to compete for outlets;
Physical knobs + buttons: Physical controls for air conditioning, volume, and driving modes ensure uninterrupted driving;
Panoramic sunroof: With only 15% light transmittance, it provides sun protection and heat insulation, preventing eye strain for children during naps.
Cockpit atmosphere: Standard ambient lighting, fragrance system, and ANC active noise cancellation provide a level of quietness comparable to luxury brands.

Song Ultra EV's breakthrough: In the 180,000 RMB price range, it's the only model that simultaneously offers 700km+ range, 800V fast charging, LiDAR intelligent driving, and a factory-installed double bed. It doesn't pursue being the "most expensive," but rather the "most understanding of you."
The arrival of the 2026 Song Ultra EV marks BYD's transformation from a "technology exporter" to a "lifestyle solutions provider." It lacks flashy four-wheel drive and exaggerated performance, but with its 710km range, 10-minute fast charging, and reclining rear seats, it answers the most basic question from families who love to travel:
"I want a car that can take the whole family far, park securely, and sleep soundly." It's more than just an SUV; it's a mobile living cabin for families who love to travel.
