The 2026 BYD SEALION 05 EV officially launched on April 20, 2026. As a revitalized flagship model within the "Ocean Network" series—positioned as an all-around, comfort-focused A-class SUV—the entire lineup is built upon the second-generation Blade Battery platform and the DiLink 100 intelligent cockpit system, establishing a new benchmark for smart family mobility. The vehicle measures 4620×1860×1630 mm, boasts a wheelbase of 2770 mm, and features a five-seat configuration with a completely flat rear floor. It offers a trunk capacity of 450 liters and comes standard with a 110-liter front trunk (frunk), striking an excellent balance between practicality and spatial flexibility.
All models feature a 15.6-inch adaptive rotating central touchscreen display powered by the DiLink 100 intelligent cockpit system. Integrated features include 50W wireless fast charging, a column-mounted electronic shifter, dual-zone automatic climate control, and a magnetic LED vanity mirror with soft lighting. Higher-trim models are equipped with an intelligent cooling and heating refrigerator (with a temperature range of -6°C to 50°C), creating an immersive and comfortable mobile space for the family. The chassis utilizes a suspension setup consisting of front MacPherson struts and a rear multi-link independent system; higher-trim models offer the option of the "DiSus-C" intelligent chassis system, which enables millisecond-level damping adjustments to ensure a harmonious blend of urban driving comfort and cornering stability.
The entire lineup adopts a rear-mounted single-motor, rear-wheel-drive layout, with no all-wheel-drive variants available. The powertrain focuses on efficiency and smoothness, enhancing the stability and comfort of both daily commutes and long-distance journeys.
Equipped with a 57.545 kWh second-generation Blade Battery (Lithium Iron Phosphate chemistry), this model offers a CLTC-rated pure electric driving range of 540 km, effectively meeting the "anxiety-free" mobility needs of urban commuting and short weekend trips. The drive motor delivers a maximum power output of 200 kW and a peak torque of 310 N·m, enabling a 0–100 km/h acceleration time of approximately 6.6 seconds, characterized by swift and linear power response. It supports BYD Flash Charging technology, requiring only 9 minutes to charge from 10% to 97% SOC (State of Charge), and can replenish up to 90% charge in just 5 minutes—setting an industry benchmark for charging efficiency. The entire lineup comes standard with the DiPilot 100 Advanced Driving Assistance System. Powered by the NVIDIA Orin N chip (delivering 84 TOPS of computing power), the system supports a suite of advanced functions—including Highway NOA (Navigate-on-Autopilot), Automatic Parking, Lane Keeping, and Active Braking—to deliver intelligent assistance that prioritizes both safety and convenience.
The exterior design features a closed-off front fascia complemented by a continuous, C-shaped LED daytime running light strip, while the rear is distinguished by a wave-patterned, full-width taillight assembly; the overall aesthetic is minimalist and high-tech. The interior offers a choice of two dual-tone themes—"Almond Beige" and "Twilight Blue"—and incorporates soft-touch materials to enhance tactile quality and create a warm, family-friendly cabin atmosphere.
Building upon the foundation of the 540 Pilot Edition, this model is equipped with a 57.545 kWh Blade Battery and a 200 kW electric motor. Its CLTC-rated electric range remains at 540 km, with charging performance identical to that of the base model.
The intelligent driving system has been upgraded to the DiPilot 100 Advanced Version. Featuring a more comprehensive sensor hardware suite, it now supports Urban NCA (Navigate-on-Autopilot), Automatic Lane Changing, Traffic Light Recognition, and Memory Parking—providing full-scenario coverage for urban commuting needs.
A new optional feature—the "DiSus-C" Intelligent Chassis System—has been introduced. This system enables dynamic body posture adjustments in milliseconds, effectively suppressing body roll and mitigating bumps to enhance stability during high-speed cruising and cornering. The interior comes standard with a built-in cooling/warming refrigerator; additionally, storage space in both the front trunk and the rear cabin has been optimized to further enhance convenience for family travel.
Equipped with a second-generation 68.547 kWh Lithium Iron Phosphate (LFP) Blade Battery, this model sees its CLTC-rated pure electric range extended to 630 km, providing greater range assurance for inter-city travel and frequent daily use. The drive motor power has been upgraded to 240 kW, delivering a peak torque of 350 N·m; with a 0–100 km/h acceleration time of just 5.9 seconds, its dynamic performance rivals that of high-performance electric vehicles.
The intelligent driving system features the DiPilot 300 LiDAR Edition (optional), equipped with a 192-line mechanical LiDAR and an NVIDIA Orin X chip (delivering 254 TOPS of computing power). This enables advanced Level 3 functions—such as hands-free navigation in urban areas, automatic roundabout negotiation, narrow-road maneuvering, and automatic obstacle avoidance—while achieving industry-leading levels of perception accuracy and decision-making capability.
The entire model lineup comes standard with the Cloud-C intelligent chassis system; when paired with the rear-wheel steering system, it delivers a handling experience characterized by agility at low speeds and stability at high speeds. The exterior is available in two exclusive color options—Coral Orange and Seashell Pink—while the wheels feature an 18-inch, multi-spoke, low-drag design, further accentuating the vehicle's youthful appeal and personalized style.
