Spy photos of BYD’s upcoming full-size flagship sedan — internally nicknamed “Big Han” — have surfaced in China, giving the clearest look yet at the brand’s most ambitious passenger car to date. The lightly-camouflaged prototype was photographed at street level and reveals a stretched, low-slung sedan with a long wheelbase, fastback roofline and a clear visual lineage to the Han L. According to information disclosed by BYD ahead of the launch, the production model will be offered with both plug-in hybrid and pure-electric powertrains and will headline a top-trim version delivering over 1,000 km of range.
BYD Wang Chao (Dynasty) network sales general manager Lu Tian has also taken to Weibo to launch a public naming campaign for what he describes as the “first D-class flagship sedan in BYD’s Dynasty lineup” — strongly implying the production car will sit above the existing Han series and re-set BYD’s flagship sedan benchmark.
Spy Shot Highlights: Long, Low, Fastback Proportions
The most striking thing about the prototype is its scale. Even under light camouflage wrap, the wheelbase looks dramatically longer than the current Han L, and the body sits much closer to D-class luxury-sedan proportions than to a typical mid-size E-class car:
- Front end echoes the Han L’s clean horizontal “blade” trim that connects the two headlight clusters across the bonnet leading edge
- Front bumper is more aggressive and detailed than the Han L’s, reinforcing the flagship intent
- Side profile is notably long with a fastback drop from the B-pillar — the silhouette is firmly in luxury-coupe-sedan territory
- Multi-spoke alloys follow a quieter, more elegant pattern than BYD’s sportier Ocean-network designs
- Decorative trim on the front fender and front doors picks up the Han L’s signature detailing — a deliberate Dynasty family cue
- Full-width LED taillight strip at the rear, similar in concept to the Han L but mounted on a re-shaped tailgate
- Rear bumper is fully covered in camouflage wrap, but the outline hints at a distinct, more elaborate design than the Han L
Interior: Tang-Style Layout, Dynasty Steering Wheel
Earlier interior spy shots have indicated that the “Big Han” cabin will follow the layout philosophy of the new BYD Tang rather than the existing Han — meaning a wider, more horizontal dashboard, a large rotating central touchscreen and a familiar Dynasty-series steering wheel. The visual treatment is expected to be more formal than the Tang’s, reflecting the flagship’s executive-sedan brief.
Powertrains: PHEV + BEV, Top Trim Over 1,000 km
BYD has already publicly indicated two top-trim variants for the new flagship sedan:
- 880 km AWD Premium — top-spec dual-motor variant with LiDAR-equipped ADAS hardware
- 1,008 km RWD Flagship — single-motor rear-drive version optimised for range, also with LiDAR ADAS
Both variants will use BYD’s second-generation Blade battery and the brand’s recently introduced “Flash Charge” (高压超充) high-voltage fast-charging technology — the same architecture currently making headlines on the Han L and on the upcoming Tang flagship. The car will also be offered in plug-in hybrid form, which is expected to push combined-range numbers even higher when measured under China’s CLTC cycle.
What Pricing Could Look Like
BYD has not disclosed pricing, but a D-class flagship within the Dynasty network would logically land above today’s Han L range. A reasonable starting expectation is the RMB 300,000–500,000 (about USD 41,380–68,970 at 1 USD ≈ 7.25 CNY) band, with the top BEV flagship potentially crossing into the RMB 450,000+ tier if it ships with the brand’s most advanced “Eye of God” ADAS suite, air suspension and a full premium interior package.
That positions the car not against the existing Han or Tang, but against the NIO ET9, IM L7, Zeekr 001, Hongqi EH7 and the lower trims of the Mercedes-Benz EQE and BMW i5. It would also be BYD’s most direct attempt yet to challenge the premium German executive-saloon segment from inside the Dynasty network — historically a more mass-market sub-brand of the BYD group.
Launch Timing and Naming Campaign
According to BYD’s prior disclosures, the new flagship sedan is targeting a third-quarter 2026 launch. With Lu Tian’s public naming campaign now underway, the brand is clearly preparing the audience for a high-profile reveal in the second half of the year. Owners and fans can leave naming suggestions on Weibo; BYD has previously used similar crowdsourced naming campaigns for the Sea Lion 07 and the original Han, with the winning suggestion becoming the car’s official commercial name.
Why It Matters
The Han series is one of BYD’s most strategically important nameplates. It was the model that initially pushed BYD into the premium sedan conversation in 2020, and the Han L has more recently been BYD’s most credible attempt at a true “Tesla Model S-tier” technical showcase. A genuine D-class flagship sedan above the Han L — built on second-generation Blade batteries, capable of over 1,000 km of single-charge range, and offered in both PHEV and BEV form — would re-set BYD’s halo product story, give the Dynasty network a true status sedan, and intensify pressure on the NIO ET9, IM L7 and emerging Huawei-Stelato S9 alternative.
