BYD Seagull 2 leak: 4.2m body, roof lidar, Flash Charge tip

China’s cheapest BYD EV is about to stop being a tiny four-seater city pod — and the filing paperwork already looks like a different car.

The second-generation BYD Seagull (sometimes nicknamed the “Great Seagull” / “Flash Charge Gull” in Chinese coverage) has cleared MIIT regulatory filings, gotten official design teasers, and — in the last few days — cabin reveals plus spy shots that tip Flash Charge branding. Treat Flash Charge packaging and final prices as rumours until BYD puts them on a slide. Dimensions, motor power, and the optional LiDAR variant are the solid parts.

TL;DR

• Second-gen Seagull: 4,205 × 1,810 × 1,570 mm, 2,650 mm wheelbase, five seats.
• Motor: 95 kW (up from 55 kW); LFP packs tipped at ~30 / 39.2 kWh, CLTC ~320 / 420 km.
• High trim: optional roof LiDAR + radars → God’s Eye B / DiPilot 300 talk.
• Fresh tip: spy shots near a Flash Charge station; Blade Battery 2.0 / ~9-minute charge claims still soft.
• China launch: tipped still in 2026; date TBA.

The car got longer — on paper and in sketches

BYD’s September design teasers finally own the “second-generation Seagull” name after months of “Big Seagull” chatter. The shape in the sketches is still a compact hatch, just stretched toward Dolphin territory.

MIIT filing numbers circulating since July (and repeated in September coverage):

	First-gen	Second-gen (filed)
Length	3,780 mm	4,205 mm (+425)
Width	1,715 mm	1,810 mm
Height	1,540 mm	1,570 mm
Wheelbase	2,500 mm	2,650 mm (+150)
Seats	4	5
Peak motor	55 kW	95 kW
Top speed (filed)	130 km/h	150 km/h

Battery cards in secondary reporting: ~29.99 / 39.23 kWh LFP with CLTC ranges around 320 / 420 km. Those are filing / leak figures — wait for the official range slide.

Cabin teasers: more family hatch than city toy

CarNewsChina and Autohome-sourced cabin shots that landed around September 25 show a horizontal screen layout, a cleaner floating-console vibe, and materials aimed above the old Seagull’s bare-bones cabin. This is BYD arguing the car is now a small family EV, not just a last-mile hatch.

LiDAR on a cheap BYD — again, but bigger

One MIIT variant optionally lists a roof-mounted LiDAR plus front / rear / side radar. Chinese coverage maps that stack to God’s Eye B (DiPilot 300) navigation-assisted driving. BYD already put optional LiDAR on the refreshed 2026 Seagull; the second gen keeps that idea while the body grows into five-seat territory.

Exact feature list, city vs highway NOA wording, and which trims get the sensor for free vs as a pack are still open. Don’t quote a full ADAS menu from forum posts.

Flash Charge is the shareable rumour — and the softest one

Chinese tips and VP-side “Flash Charge Gull” nicknaming push the idea that BYD wants Megawatt-class / high-power Flash Charging and Blade Battery 2.0 down into its cheapest EV. Fresh spy shots show a camouflaged Seagull staged in front of a Flash Charge station mockup — classic pre-photoshoot theatre.

Claims floating with those shots (treat as tipster / marketing preview, not a locked card):

• ~5 minutes for 10→70%
• ~9 minutes for 10→97%
• Instantaneous peaks talked up toward ~300 kW, then tapering
• Likely limited to higher trims / the larger pack

BYD has not published an official Seagull Flash Charge spec sheet as of this writing. The MIIT numbers and the design teasers are firmer than the charging story.

What to watch next

1. Invite date — “within 2026” is the repeated China window; an exact night would harden the timeline.
2. Which trims get LiDAR / God’s Eye B — and at what add-on cost.
3. Whether Flash Charge + Blade Battery 2.0 actually ship on Seagull, or only on more expensive BYDs.
4. Price — grow the car 425 mm and keep it “cheapest EV” and something has to give: range, trim, or sticker.
5. Export naming — first-gen Seagull wears Atto 1 / Dolphin Mini / Dolphin Surf badges abroad; second-gen naming is still fog.

Until BYD locks charging and pricing: the size jump and LiDAR filing are real enough to write; the Flash Charge theatre is the hook that still needs a stage.
