Exterior Design
The BYD Seal 08 DM adopts the “Ocean Aesthetics 2.0” design language, featuring a wide-body, low-slung coupe silhouette with a drag coefficient as low as 0.22 Cd. The front fascia features a closed grille, with highly distinctive wave-shaped split daytime running lights that, paired with sharp headlight clusters and front-end character lines, exude a strong sense of sportiness; The 5.15-meter-long, sleek fastback profile on the side is complemented by hidden door handles and 19-inch multi-spoke wheels, with a LiDAR sensor mounted on the roof; the rear features full-width, wave-shaped taillights, and a small ducktail spoiler that enhances its sporty character, striking a balance between youthful dynamism and executive-class sophistication.
Interior Design
The BYD Seal 08 DM features a light-luxury cabin, wrapped in generous amounts of genuine leather and iridescent mother-of-pearl trim. Paired with a floating center console screen, a fully digital instrument cluster, and a column-mounted gear selector, the interior exudes simplicity and sophistication. The seats offer ventilation, heating, massage, and zero-gravity modes, while the rear cabin offers class-leading space, complete with individual control screens, multi-layer soundproof glass, and active noise cancellation—delivering maximum quietness. With dimensions of 5150×1999×1505mm and a wheelbase of 3030mm, the vehicle meets standard mid-to-large sedan specifications. The extra-long 3030mm wheelbase provides three fists’ worth of rear legroom, while the fastback design ensures ample headroom, making it suitable for both family use and business hospitality.
Powertrain
The entire BYD Seal 08 DM lineup is built on an 800V high-voltage platform and features a high-efficiency 1.5T hybrid powertrain. It offers a pure electric range of 300 km, a combined range of 1,310 km, and a fuel consumption of 4.6 L/100 km when running on gasoline, eliminating range anxiety while balancing performance and economy. Chassis Standard features include the Yunnian-A air suspension and rear-wheel steering, reducing the turning radius to 5.4 meters. This delivers class-leading handling agility while balancing comfort and sportiness.
