BYD Files All-New Han and Third-Gen Qin Plus as Sedan Lineup Gets a Rethink

BYD has pushed two of its longest-running sedan nameplates into China’s regulatory pipeline, with the all-new Han and a third-generation Qin Plus both turning up in the 412th batch of vehicle filings published by the Ministry of Industry and Information Technology.

The filings give us the hard numbers before any official launch event. The new Han stretches to 5,156 mm in length and 1,969 mm in width, riding on a 3,030 mm wheelbase. Against the Han EV Flash Charging Edition that arrived in April, that works out to 161 mm more length, 59 mm more width and an extra 110 mm between the axles. It is a meaningful stretch, not a light nip and tuck.

Four Han Variants, One PHEV

Three of the filed Han models are battery-electric and one is a plug-in hybrid, all five-seaters. The electric side breaks down into two single-motor rear-drive versions rated at 245 kW and 300 kW, both capped at 240 km/h, plus a dual-motor all-wheel-drive flagship that pairs a 200 kW front unit with a 320 kW rear motor for 520 kW combined and a 270 km/h top speed. The PHEV combines a 1.5-liter engine with a 200 kW electric motor and tops out at 200 km/h.

Worth keeping straight: this is a different car from the Da Han that BYD unveiled on October 13. The Da Han sits above it in the range at 5,256 mm long with a 3,130 mm wheelbase.

Why the Han Needs This Refresh

The timing is not accidental. Han series sales hit 2,529 units in September, down 70.90% year-on-year and 30.83% versus August. Through the first nine months of 2026 the family has moved 44,324 cars, a 68.86% slide from a year earlier. For a nameplate that once anchored BYD’s push upmarket, those are uncomfortable numbers, and a bigger, more powerful generation is the obvious response.

Qin Plus Grows Up

The third-generation Qin Plus in the filing is the EV version: 4,840 mm long, 1,900 mm wide, 1,498 mm tall, with a 2,800 mm wheelbase. It carries a permanent-magnet synchronous motor peaking at 100 kW and a lithium iron phosphate pack, with a 170 km/h top speed.

Lu Tian, who runs sales for BYD’s Dynasty line, teased the car on Weibo the same day, talking up the extra size and cabin space and promising more details soon. The images in his post showed the DM-i plug-in, while the regulatory documents cover the pure-electric variant.

It has already been a busy year for the Qin family. January brought the 2026 Qin Plus DM-i and longer-range Qin L DM-i variants, both pushing maximum CLTC electric range to 210 km. August added the Qin Max, slotted above the Qin L and offered in both EV and PHEV form.

BYD is clearly working through its sedan roster from top to bottom. The Seagull gets its own second-generation launch on October 20, so the next few weeks should fill in more of the picture.
