Front Face Design
The front face design of BYD SEALION 7 is based on "ocean aesthetics" and integrates the forward-looking language of the Ocean X concept car, showing a strong sense of sportiness and technological tension.

Body Design
The body proportions of SEALION 7 break the traditional SUV framework, achieving a "large five-seat" layout with a length of 4830mm + a wheelbase of 2930mm, while retaining the smooth lines of a crossover coupe.

Tail Design
The taillights are composed of 128 LED beads. The low-hanging shapes at both ends simulate the surface tension of the waves, and when lit, they present a dot matrix gradient effect. The black diffuser at the bottom integrates a guide groove to optimize the tail airflow.

Comfortable Cockpit
The center console adopts the "floating wing" instrument panel and the "ocean core" center console layout. 80% of the interior is wrapped in Nappa leather and Alcantara material, with water ripple quilting and double stitching technology, which has a delicate touch.


Four-spoke Floating Steering Wheel
The steering wheel is wrapped in Nappa leather and stitched with Alcantara material, which has a delicate grip and is non-slip. The 3 o'clock and 9 o'clock positions adopt a "dolphin fin" shape, which fits the curvature of the palm and is not easy to get tired after long-term driving. The flat bottom design further increases the leg space, and with the electric four-way adjustment (up and down/front and back), it can quickly adapt to the sitting posture needs of different drivers.
Instrument Screen
The 10.25-inch full LCD instrument uses a 2K resolution floating curved screen, which displays information including vehicle speed, endurance, power consumption, navigation path, intelligent driving status, etc. It supports multiple theme switching (such as "Ocean Blue" and "Racing Red"), and the interface style automatically adapts in different driving modes.


Central Control Screen
SEALION 7's 15.6-inch rotating Pad is equipped with the DiLink 100 smart cockpit system, with a screen resolution of 2.5K, supporting a high refresh rate of 120Hz, and a touch response delay of less than 80ms. The screen can automatically rotate according to the application type (such as horizontal screen for navigation and vertical screen for video), and with the 6nm 5G chip, multi-tasking runs smoothly, and the application startup speed is increased by 40%.
Crystal-cut Electronic Gear Lever
The SEALION 7 electronic gear lever is made of crystal material with 50-faceted three-dimensional cutting technology. The gear lever grip area is ergonomically designed, with moderate operating damping. It supports direct selection of four gears: P/R/N/D. With the automatic parking function, there is no need to frequently switch gears when parking.


Front Power Supply
The front power supply system of SEALION 7 uses 50W air-cooled wireless charging, 65W PD fast charging, and dual cigarette lighter layout. Its hardware parameters are leading in the same class, and the software logic is close to user needs.
Front Seats
The seats are wrap-around sports seats, and the side wings are covered with suede material, providing good lateral support when cornering at high speed. The seat surface uses 3D diamond quilting technology to enhance the wrapping feeling, and with Nappa leather + Alcantara stitching, it has a delicate touch and excellent breathability.


Panoramic Sunroof
The SEALION 7 series is equipped with a 2.1㎡ large panoramic sunroof as standard, with a glass thickness of 5.5mm, a UV blocking rate of >99%, and a heat insulation rate of >85%. High-end models are equipped with an EC intelligent dimming sunroof, which supports 11 levels of light transmittance adjustment (1%-99%), and can switch between "transparent", "soft light" and "privacy" modes through the touch panel or voice commands.
Rear Space
The 2930mm ultra-long wheelbase, combined with a flat floor, provides 980mm of rear legroom (a passenger with a height of 180cm has a knee 3 fists away from the front seat).
Headroom: 985mm, the roof adopts a dome-style design, combined with a panoramic skylight, it looks more spacious visually.


Rear Seats
The rear seats of SEALION 7 are made of high-density slow-rebound sponge, with a cushion length of 500mm (50mm longer than the same level), which provides more support for the thighs. The backrest and headrest adopt the "dolphin fin" bionic curve to fit the human spine. It supports 6 levels of backrest adjustment (10°-32°), and high-end models have added electric backrest adjustment and seat heating (three levels adjustable).
Trunk
SEALION 7 comes standard with an inductive electric tailgate, which supports height memory and foot-sensing opening, and the maximum opening height of the tailgate is 1.85m. There is a 20L sunken storage compartment under the cover, which can store charging guns, first aid kits and other items.
With the V2L external discharge function (optional), outdoor equipment can be powered through the trunk power interface (maximum power 3.3kW).

Platform And Performance
The Sea Lion 07 EV is built on BYD's e-platform 3.0, equipped with CTB (battery body integration) technology, supports up to 230kW fast charging, and has a CLTC range of up to 610 kilometers. Its dual-motor four-wheel drive version can accelerate from 0 to 100 km in just 4.2 seconds, and its power performance is comparable to that of the Tesla Model Y.

DiPilot 100 Advanced Intelligent Driving
SEALION 7 supports high-speed pilot assistance (automatic lane change/overtaking), automatic parking (including vertical/lateral parking spaces), and remote parking. The hardware is equipped with 5 millimeter-wave radars + 12 ultrasonic radars + 4 surround-view cameras, surpassing competitors of the same price with L2+ level assisted driving.
