The first-generation BYD Seal 06 DM-i debuted at the 2024 Beijing Auto Show in April,[2][3] and launched in China on 28 May 2024. It shares BYD's fifth-generation plug-in hybrid system marketed as DM-i 5.0 with the Qin L from the 'Dynasty Series'.[4]

Design and equipment

The exterior of the Seal 06 DM-i adopts the design language from the BYD Ocean vehicle series. It features a closed front fascia, door handles of an outward-flip design, a transparent taillight bar and an illuminated BYD logo on the rear boot lid.[2][4]

For the suspension, the Seal 06 DM-i has MacPherson struts at the front and a E-type four-link independent setup at the rear.[4]

Inside, the Seal 06 DM-i carries over the Ocean series design for the dashboard and doors. There is a 8.8-inch LCD digital instrument cluster and a rotatable 15.6-inch central touchscreen infotainment system.[4]

The station wagon model was unveiled in April 2025 at the Shanghai Auto Show,[5] and was launched in China on 4 July 2025.[6] The station wagon has a maximum boot capacity of 1,535 L (54.2 cu ft) when the rear seats are folded down, it has a built-in refrigerator with a heating function and the V2L (Vehicle-to-Load) function.[6]
