The BYD Seal 07 (), previously the BYD Seal DM-i until 2024, is a full-size sedan manufactured by BYD Auto since 2023. It was only available as a plug-in hybrid known as the Seal 07 DM-i until the 2026 model year, when a battery-electric version known as the Seal 07 EV was introduced.
First generation (2023)
History The Seal DM-i was first introduced as a prototype at 2023 Auto Shanghai named the BYD Destroyer 07 and was planned to be the third product of the Warship Series model line. However, plans were changed in July 2023 just months before launch and it was launched as the Seal DM-i instead, to integrate it with the Seal series of sedans.
Overview Sold through Ocean Network dealerships, the Seal DM-i is positioned in the BYD's range as an alternative to the similar BYD Han, which belongs to Dynasty Network dealerships. It went on sale in September 2023 in China.
The stylistic design by Wolfgang Egger was maintained in the next generation of aesthetics already known from the electric Seal, distinguished, among others, muscular wheel arches, slim roofline and boomerang-shaped headlights. The rear lamps took the shape of water drops, dominating the band in the composition with a chrome strip. The cabin has a design identical to other models in BYD's Ocean Series product line. The central element of the dashboard is the 15.6-inch touchscreen of the multimedia system.
2025 facelift On 21 August 2025, BYD officially introduced the facelifted Seal 07 DM-i in China, marketed as the BYD Seal 07 DM-i. The facelift brings a slight increase of dimensions, and brings the Seal 07 DM-i more in line with recent BYD Ocean series models, such as redesigned headlights and a grille repositioned to the lower air intake. The integration of a roof-mounted lidar sensor allows for BYD's “God’s Eye-B” (DiPilot 300) intelligent driving assistance system. It carries over the 5th-generation DM-i powertrain from the pre-facelift model.
Seal 07 EV (2026) For the 2026 model year, BYD officially introduced the Seal 07 EV in China on 1 March 2026. It went on sale during BYD's Technology Day on March 5, 2026. It shares its body and design with the Seal 07 DM-i, which continues to be sold.
Powertrain Unlike the BYD Han, the BYD Seal 07 DM-i only uses a front wheel drive instead of both available as a DM-p or DM variant and all-wheel drive which allows the fullsize car turning radius fits into narrow space.
The electric version of a BYD Seal 07 EV powertrain details isn't released, which uses an e-Platform 3.0 Evo platform that is expected to available in rear-motor rear-wheel drive or dual-motor all-wheel drive.
The Seal DM-i was launched with a choice of two different petrol engine options. The standard engine was a 1.5-liter naturally aspirated inline-4 with port injection, a compression ratio of 15.5:1 and set in Atkinson cycle, and outputs ( net power) at 6,000rpm and of torque at 4,500rpm. The upgraded engine is a 1.5-liter turbocharged inline-4 with direct injection, a compression ratio of 12.5:1, and set in Miller cycle, which outputs ( net power) at 5,200rpm and of torque from 1,3504,000rpm.
In August 2024, both engine options were updated as part of the 2025 facelift. The standard engine now outputs ( net power) at 6,000rpm and of torque at 4,500rpm, and has a compression ratio of 16:1 a peak thermal efficiency of 46.1%. The upgraded engine now outputs ( net power) at 5,500rpm and of torque from 2,5004,500rpm, and has a compression ratio of 14:1 and a peak thermal efficiency of 45.03%.

Second generation (2026)
The second generation Seal 07 was revealed through China's MIIT filings on 7 Aug 2026. Similar to its predecessor, both DM-i (plug-in hybrid) and EV (battery electric) variants share the same body and dimensions, only differing in badging
The exterior design of the Seal 07 takes cues from the BYD Ocean series' latest Ocean Aesthetics 2.0 design language seen in the larger Seal 08 and Sealion 08, including split headlights in the front with a distinctive dual light signature, and wave-shaped taillights. Some variants are equipped with a roof-mounted LiDAR sensor.
Powertrain The second generation Seal 07 is available with either battery electric or plug-in hybrid powertrains.
There are two single motor battery-electric variants producing and of power respectively. Both use lithium iron phosphate (LFP) batteries from FinDreams.
The plug-in hybrid (DM-i) variant uses a 1.5-liter turbocharged engine producing a peak power of ( net power), an electric motor producing and a 38.029kWh lithium iron phosphate (LFP) battery.
