BYD Seal 07 Specs, Range, Battery, Dimensions & Features

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.

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.

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.

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.

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 81 kW (109 hp) (78 kW (105 hp) net power) at 6,000rpm and 135 N⋅m (100 lb⋅ft) 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 102 kW (137 hp) (96 kW (129 hp) net power) at 5,200rpm and 231 N⋅m (170 lb⋅ft) of torque from 1,350–4,000rpm.

In August 2024, both engine options were updated as part of the 2025 facelift. The standard engine now outputs 74 kW (99 hp) (70 kW (94 hp) net power) at 6,000rpm and 126 N⋅m (93 lb⋅ft) 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 115 kW (154 hp) (110 kW (148 hp) net power) at 5,500rpm and 225 N⋅m (166 lb⋅ft) of torque from 2,500–4,500rpm, and has a compression ratio of 14:1 and a peak thermal efficiency of 45.03%.

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 245 kW (329 hp) and 300 kW (400 hp) 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 115 kW (154 hp) (110 kW (148 hp) net power), an electric motor producing 160 kW (210 hp) and a 38.029 kWh lithium iron phosphate (LFP) battery. It has an electric-only CLTC range of 245 km (152 mi).
