In 2025, BYD retained its title as the world's Best-selling new energy vehicle (NEV) manufacturer, with annual sales exceeding 4.6 million units. The Ocean Series was a key contributor to this milestone, delivering over 2.22 million units for the year —up 14.05% year on year — and serving as the volume backbone of BYD's overall sales.
With scale advantages now firmly unlocked, BYD is reinforcing its competitive moat through generational upgrades to its core components and systems. As the first BYD model to feature both the second-generation Blade Battery and high-voltage flash charging technology, the Seal 07 EV is not only the brand's flagship weapon in its assault on B-segment sedan market, but also marks the beginning of a comprehensive upgrade cycle across the company's entire component ecosystem.
Market Positioning & Value Proposition
Built on the strength of this integrated ecosystem, the Seal 07 EV targets the RMB 150,000–200,000 price band — the primary battleground for NEV penetration and core volume growth segment in China. Leveraging BYD's powerful scale-driven cost efficiency and full-stack vertical integration , the Seal 07 EV brings previously premium technologies — including advanced intelligent driving and high-performance powertrain systems— down to an entry price of just RMB 169,900, making "technology democratization" a reality. This extreme resource integration redefines the value benchmark for mid-size pure-electric sedans and positions the model to sustain its leadership in this critical segment through 2026.
Powertrain & Charging Performance
On the powertrain front, the Seal 07 EV is equipped with a world-first 12-in-1 Intelligent Electric Drive System, delivering a peak output of 240 kW and peak torque of 305 N·m. Empowered by BYD's Cell-to-Body (CTB) technology, system integration efficiency is significantly enhanced, achieving an energy consumption as low as 10.8 kWh per 100 km.
The core energy storage unit is a 69.07 kWh second-generation LFP Blade Battery, enabling a CLTC range of up to 705 km. Regarding energy replenishment, the 800V flash charging architecture allows the vehicle to charge from 10% to 70% in just 5 minutes. Even in extreme cold conditions (-30°C), charging performance remains largely unaffected, ensuring consistent efficiency across all operating scenarios.
Intelligent Cockpit & Cabin Comfort
The flagship Seal 07 EV features DiLink 150, BYD's advanced intelligent cockpit system, centered around a 15.6-inch adaptive rotating floating display, a 10.25-inch full digital instrument cluster, and a W-HUD (windshield head-up display).
In terms of comfort, both driver and front-passenger seats feature multi-directional electric adjustment, lumbar support, and massage functions. Notably, both front and rear seats support ventilation and heating — breaking the convention of "downgraded" rear-seat amenities in this class. The cabin also integrates a -6°C to 50°C onboard refrigerator, a 12-speaker HiFi Dynaudio audio system, and multi-color dynamic ambient lighting, collectively redefining the quality ceiling for its price segment.
Advanced Driver Assistance (ADAS)
The Seal 07 EV comes standard with BYD's "God’s Eye" 5.0 system across all variants, extending L2+ autonomous driving capability to the entire lineup. The vehicle adopts a precision-tiered hardware strategy: the 705 Flagship trim is fitted with an NVIDIA DRIVE Orin X high-performance chip, a LiDAR unit, and the DiPilot 300 system. Supported by a redundant sensing suite comprising 11 exterior cameras, 3 millimeter-wave radars, and 12 ultrasonic radars, the high-spec configuration enables full-scenario advanced driving functions including City NOA (Navigate on Autopilot), Automated Valet Parking, and narrow-road U-turn assistance — establishing a generational capability advantage over competitors in the segment.
Chassis & Body Control
All Seal 07 EV variants come standard with DiSus-C Intelligent Damping Body Control System, incorporating a road preview function. Using the front-facing camera to scan the road ahead in real time, the system enables millisecond-level adaptive damping adjustment, dynamically optimizing suspension support and vibration absorption across varying road conditions. Combined with a rear-motor, rear-wheel-drive layout, this delivers precise body attitude control through high-frequency damping regulation — sharpening dynamic response while substantially improving ride comfort and refinement in everyday use.
