Positioned as a mid-size urban intelligent SUV and built as the inaugural model on BYD’s revolutionary e-Platform 3.0 Evo, this vehicle represents the very pinnacle of what BYD’s engineering teams have achieved to date.

For importers, distributors, and EV enthusiasts in countries such as Chile, Brazil, Colombia, and Argentina, understanding the exact specifications of the Chinese domestic version is essential. The China-market model consistently carries a more comprehensive technology stack than export variants, making it the definitive reference point for evaluating the Sealion 07 EV’s true capabilities. This in-depth review covers everything from exterior design and interior comfort to powertrain configurations, charging technology, and the intelligent driving systems that set this vehicle apart.

Exterior Design: Ocean Aesthetics Meets Urban Agility

The Sealion 07 EV is a striking embodiment of BYD’s Ocean Aesthetics design language. It seamlessly blends the flowing silhouette of a coupe with the commanding presence of a full-size SUV. At 4,830 mm in length, 1,925 mm in width, and 1,620 mm in height, with a generous 2,930 mm wheelbase, it occupies a footprint comparable to many mid-to-large SUVs while maintaining a remarkably aerodynamic profile.

The front fascia features a fully closed-off grille — a signature of modern EVs — flanked by sharp, multi-element LED headlights with adaptive automatic high/low beam switching. Flush, hidden electric door handles retract seamlessly into the body, reducing drag and lending the exterior a clean, futuristic appearance. The panoramic glass roof spans the entire cabin ceiling, and the sloping roofline flows gracefully into a sculpted rear end with a continuous LED taillight bar. Despite its substantial dimensions, the Sealion 07 EV maintains a minimum turning radius of just 5.85 meters, ensuring it handles the congested streets of São Paulo or Santiago with surprising ease.

Interior and Space: A Sanctuary of Intelligent Comfort

The Sealion 07 EV’s cabin blends minimalist luxury with a comprehensive technology suite.

Stepping inside the Sealion 07 EV reveals a cabin that prioritizes both luxury and intelligent functionality. The “Ocean Core” central console layout pairs a 15.6-inch adaptive rotating touchscreen — powered by the DiLink intelligent infotainment system — with a 10.25-inch digital instrument cluster. On premium trims, a 50-inch AR-HUD (Augmented Reality Head-Up Display) projects navigation and driving data directly onto the windshield, creating an immersive and information-rich driving experience.

The 2,930 mm wheelbase translates into genuinely spacious accommodation for all five occupants. The driver’s seat offers multi-directional electric adjustment including lumbar support, leg extension, and seat memory on higher trims. Both front seats come standard with heating and ventilation — a thoughtful inclusion for the diverse climates encountered across South America, from the high-altitude cold of Bogotá to the tropical heat of Rio de Janeiro. The cabin is further elevated by 128-color ambient lighting, a 12-speaker Dynaudio HiFi audio system on top trims, and a 50W wireless charging pad for the front row.

Practicality is equally well-considered. A 58-liter front trunk (frunk) accommodates a standard 20-inch carry-on suitcase, while the rear cargo area provides 500 liters of usable space with flexible folding configurations for family travel or cargo needs.

Powertrain and e-Platform 3.0 Evo: The 12-in-1 Revolution

The Sealion 07 EV is the world’s first production vehicle built on BYD’s e-Platform 3.0 Evo, and the centerpiece of this platform is the globally unprecedented 12-in-1 intelligent electric drive system. This highly integrated unit consolidates the motor, motor controller (featuring 1,200V silicon carbide power electronics), battery management system, vehicle control unit, DC-DC converter, on-board charger, and multiple thermal management components into a single compact assembly. The result is reduced weight, improved efficiency, and a motor capable of spinning to a world-record 23,000 rpm in mass production.

The Chinese domestic market offers the Sealion 07 EV in three distinct powertrain configurations:

The flagship 550 AWD Performance model pairs a 160 kW asynchronous AC front motor with a 230 kW permanent magnet synchronous rear motor, delivering a combined 690 N·m of torque and a 0–100 km/h sprint time of just 4.2 seconds — performance figures that rival dedicated sports cars. All variants benefit from multiple driving modes including Sport, Standard, Economy, and Snow, alongside an intelligent energy regeneration system.

Battery, Range, and Ultra-Fast Charging

240 kW DC fast charging means 10–80% in just 25 minutes — no more range anxiety.

The Sealion 07 EV is equipped with BYD’s proprietary Blade Battery, a lithium iron phosphate (LFP) cell-to-pack design renowned for its exceptional thermal stability and longevity. The 550 km variants utilize a 71.8 kWh pack, while the 610 km and AWD versions are fitted with a larger 80.64 kWh battery. All figures are measured under the CLTC (China Light-Duty Vehicle Test Cycle) standard.

Charging technology is a defining strength of the e-Platform 3.0 Evo. The 610 km and AWD models support an 800V high-voltage architecture, enabling peak DC fast charging at up to 240 kW. This allows a charge from 10% to 80% in approximately 25 minutes, while BYD’s proprietary intelligent terminal fast-charging technology completes the final 80% to 100% segment in just 18 minutes — a significant improvement over conventional systems. The standard 550 km model supports up to 180 kW on compatible DC chargers. Additionally, the full-range intelligent wide-temperature heat pump system extends cold-weather range by up to 45 km and normal-temperature range by 60 km, making the Sealion 07 EV a genuinely all-season vehicle.

Chassis and Handling: DiSus-C Intelligent Damping

Underpinning the Sealion 07 EV is a sophisticated chassis architecture: a double-wishbone independent front suspension paired with a five-link independent rear suspension. All models come standard with FSD (Frequency Selective Damping) shock absorbers, which passively adjust their damping characteristics based on road frequency inputs, delivering a balance of ride comfort and dynamic handling without compromise.

The top-tier AWD Performance model elevates this further with the DiSus-C (Yunchen-C) intelligent damping body control system. This active suspension technology monitors road conditions and vehicle dynamics in real time, adjusting shock absorber stiffness hundreds of times per second to minimize body roll in corners, reduce pitch under braking, and absorb road imperfections with remarkable composure. Paired with the iTAC (Intelligent Torque Adaption Control) system — which redistributes torque between axles and individual wheels in milliseconds — the AWD Sealion 07 EV offers a level of dynamic capability and all-weather confidence that is exceptional in its class.

Intelligent Features: DiPilot Smart Driving System

The DiPilot 300 system uses dual Nvidia Orin-X chips and LiDAR for comprehensive L2+ autonomous driving.

The Sealion 07 EV’s intelligent capabilities extend well beyond its infotainment system. The DiLink smart cockpit, running on a dedicated D100 chip with 12 GB of RAM and 256 GB of storage, supports 5G connectivity, full OTA (Over-the-Air) software updates, and a comprehensive smartphone app for remote vehicle management including climate pre-conditioning, charging scheduling, and real-time location tracking.

The “Eye of the Gods” DiPilot ADAS suite is offered in two tiers depending on the trim level:

The DiPilot 300 system, powered by dual Nvidia Orin-X chips delivering 254 TOPS of computing power and supplemented by a dedicated LiDAR sensor, enables Navigate on Autopilot (NOA) on both highways and urban roads. This includes automatic on/off-ramp navigation, intelligent lane changing, and advanced obstacle avoidance — capabilities that represent the leading edge of L2+ autonomous driving technology available in a production SUV today.

Safety: CTB Architecture and Blade Battery

BYD’s commitment to safety is architecturally embedded in the Sealion 07 EV. The vehicle employs CTB (Cell-to-Body) technology, integrating the Blade Battery directly into the vehicle’s structural floor. This approach increases regional body strength by 60% compared to conventional construction, dramatically improving torsional rigidity and crash energy absorption.

Standard safety equipment across all trims is comprehensive: 11 airbags (including a central airbag between the front seats), ABS, ESC, direct tire pressure monitoring, Automatic Emergency Braking (AEB), Lane Departure Warning, Lane Keeping Assist, Blind Spot Monitoring, and a 360-degree surround-view camera system. The Blade Battery itself, with its unique flat cell architecture, has passed extreme safety tests including nail penetration, crush, and overcharging without fire or explosion — a standard that sets it apart from conventional lithium-ion battery packs.
