BYD is redefining the plug-in hybrid landscape with the 2026 SEALION 6 Dm-i, a vehicle that promises an exceptional 1,670 km of combined range and rapid charging capabilities, all while starting at a remarkably accessible price point of RMB 139,800 (approximately $19,660). This new offering from BYD leverages its advanced DM-i hybrid technology, pairing an efficient 1.5-liter turbocharged engine with a substantial battery pack to deliver impressive fuel economy and substantial electric-only driving range. The SEALION 6 Dm-i is poised to challenge established players by offering a compelling blend of long-distance capability, modern amenities, and aggressive pricing, making it a standout option for budget-conscious yet range-anxious consumers.
Performance & Powertrain
The 2026 BYD SEALION 6 Dm-i is built around BYD's fifth-generation DM-i (Dual Mode intelligent) plug-in hybrid system, a technology honed to prioritize electric propulsion for maximum efficiency and refinement. At its core is a 1.5-liter turbocharged engine, producing 115 kW (154 hp) and 225 Nm of torque. This internal combustion engine primarily functions as a generator, charging the battery pack and providing power when demand exceeds the electric motor's capacity. The primary motive force comes from an electric traction motor, delivering 200 kW (268 hp) and driving the wheels, ensuring a smooth, responsive, and quiet driving experience, especially in urban environments.
This dual-mode operation allows the SEALION 6 Dm-i to achieve remarkable efficiency figures. BYD claims a fuel consumption rate of just 3.5 liters per 100 kilometers, a figure that significantly reduces running costs for owners. The system is paired with a 60 L fuel tank, contributing to the extensive 1,670 km ST (System Total) range. The battery pack, with a capacity of 26.6 kWh, provides a substantial electric-only range of 135 km to 150 km, sufficient for most daily commutes and errands to be completed purely on electric power. Acceleration from 0 to 100 km/h is quoted at a respectable 7.9 seconds, indicating adequate performance for everyday driving scenarios.
Design & Interior
The exterior of the 2026 BYD SEALION 6 Dm-i presents a modern and clean aesthetic, aligning with BYD's contemporary design language. It features full LED lighting across the front and rear, including distinctive LED headlights, high beams, and low beams, enhancing both visibility and the vehicle's premium appearance. A functional front grille design contributes to aerodynamics, while the overall silhouette suggests a practical and spacious vehicle. The car rides on 235/50 R19 tires, providing a good balance of comfort and road holding. The inclusion of two distinct exhaust outlets, though functional, hints at the hybrid powertrain's capabilities.
Inside, the SEALION 6 Dm-i prioritizes passenger comfort and practicality. The cabin offers generous legroom and headroom, creating a spacious environment for occupants. A large cargo area of 695 liters expands to 1,630 liters with the second-row seats folded down, offering significant utility for hauling luggage, groceries, or larger items. Higher trim levels are equipped with a glass roof featuring an integrated sunshade, enhancing the sense of openness. Ambient lighting further contributes to the cabin's sophisticated atmosphere. Second-row passengers benefit from dedicated amenities, including two air fans for climate control and two USB ports for device charging. While the entry-level model may lack certain advanced features, the overall interior design focuses on a comfortable and functional experience for families and daily use.
Technology & Features
The SEALION 6 Dm-i comes equipped with a suite of modern technological features designed to enhance convenience and safety. A 360-degree camera system provides comprehensive visibility around the vehicle, aiding in parking and low-speed maneuvers. For connectivity and user interaction, the vehicle supports NFC card access, offering a keyless entry solution. The infotainment system, while not detailed in its specific screen size for the base model, is expected to integrate with the vehicle's functions, and higher trims offer a wireless charger with a maximum output of 50W, capable of rapidly charging compatible smartphones.
Charging convenience is a significant focus for the SEALION 6 Dm-i. It features two charging ports, catering to both slow and fast charging methods. The battery can be replenished from 10% to 80% in approximately 20 minutes using a DC fast charger, a capability that minimizes downtime on longer journeys. Slower AC charging takes between 3 to 4 hours, suitable for overnight charging at home. Paddle shifters are included, offering a degree of driver engagement and control over the E-CVT gearbox, allowing for manual selection of simulated gear ratios or adjustment of regenerative braking levels. Higher-end versions also include a refrigerator, a feature rarely seen at this price point, further enhancing passenger comfort.
Driving Experience
The driving experience in The SEALION 6 Dm-i is characterized by the seamless integration of its electric and gasoline powertrains. The DM-i system prioritizes electric drive, meaning that initial acceleration and low-speed cruising are remarkably quiet and smooth, free from the vibrations and noise typically associated with internal combustion engines. The electric motor provides instant torque, resulting in responsive acceleration from a standstill and confident overtaking maneuvers. The E-CVT gearbox ensures a continuously variable power delivery, eliminating the sensation of gear shifts and contributing to the overall refinement of the drive.
When the 1.5-liter turbocharged engine engages, it does so with minimal intrusion, primarily functioning as a generator to maintain battery charge. This approach ensures that the engine operates within its most efficient RPM range, minimizing fuel consumption. The suspension setup, while not featuring air springs due to the vehicle's competitive pricing, is tuned to provide a comfortable ride, effectively absorbing road imperfections and providing a composed feel on various surfaces. The RWD configuration, combined with the substantial wheelbase, should contribute to stable highway cruising and predictable handling. While the absence of advanced suspension systems means it might not offer the ultimate in dynamic agility, the SEALION 6 Dm-i is engineered to deliver a comfortable and efficient journey for its occupants.

How It Compares
The SEALION 6 Dm-i enters a segment where value and range are paramount, and its pricing and specifications place it in direct contention with a range of vehicles, particularly within the Chinese market. Compared to its stablemate, the 2026 BYD Sealion 06 EV, which offers a pure electric experience, the DM-i variant provides a significantly extended total range and the flexibility of gasoline refueling for ultimate long-distance capability. While specific competitor pricing and specifications vary widely, the SEALION 6 Dm-i's sub-$20,000 starting price and 1,670 km ST range are standout figures.
Within our database, the BYD HAN DM i, a larger plug-in hybrid sedan, offers a 1,560 km combined range starting at approximately $22,500. The SEALION 6 Dm-i undercuts this significantly on price while offering a longer total range. When considering the Aito M7 REV, which ranges from $36,129 to $47,700 and offers a 200 km CLTC pure electric range, the SEALION 6 Dm-i presents a far more economical entry point for plug-in hybrid technology, albeit with different powertrain architectures and market positioning. The SEALION 6 Dm-i's appeal lies in its ability to deliver extensive travel range and practical features at a price point that makes it accessible to a broad audience.
