The BYD Sea Lion 6 DM-i, the first plug-in hybrid (PHEV) launched in South Korea, raises the question: is it an electric vehicle or a combustion engine car? If one were to assign a sorting hat from the movie 'Harry Potter' to this vehicle, it would likely classify it as an 'electric car.' Although it features both a gasoline engine and an electric motor, its platform and driving mechanism are designed more like an electric vehicle.
Upon receiving the BYD Sea Lion 6 DM-i, the first impression was intriguing. The medium-sized SUV, with its deep black exterior and robust build, exuded a sense of mystery. The rear of the vehicle features both an electric charging port and a fuel filler cap, clearly showcasing its dual nature as a plug-in hybrid.
Starting the engine revealed a total driving range of 970 kilometers on the 12.3-inch digital dashboard. The gasoline icon indicated a range of 931 kilometers, while the battery icon showed a 66% charge. The vehicle's system estimated that it could travel 39 kilometers in pure electric mode.
During a test drive from Dobong-gu to Guro-gu, the Sea Lion 6 DM-i was driven along the Eastern Highway and the Inner Circular Road. The 15.6-inch rotating intelligent cockpit seamlessly integrated Kakao Navigation, allowing for intuitive access to vehicle information and directions.
The driving experience felt generally substantial. When set to electric vehicle (EV) mode, the differences from existing BYD electric vehicles were minimal. Pressing the accelerator produced the characteristic 'whir' of the electric motor, delivering immediate torque. While the vehicle felt heavy, its movements were agile, and the quietness typical of electric cars was maintained throughout the drive.
The Sea Lion 6 DM-i is equipped with BYD's lithium iron phosphate (LFP) blade battery (18.3 kWh), allowing it to travel up to 70 kilometers in pure electric mode, making it suitable for commuting in and out of Seoul or traveling to the outskirts.
Switching to hybrid mode enhanced the feeling of driving an electric vehicle. This driving characteristic is attributed to BYD's core technology, the Dual Mode Intelligent (DM-i) system. It operates on a single platform with a 1.5-liter turbocharged gasoline engine and a liquid-cooled electric motor. Depending on the driving conditions, the system automatically switches between electric motor only, engine only, or a combination of both. However, during rapid acceleration or when climbing steep inclines, the presence of the engine became more pronounced.
While driving in hybrid mode, the battery charge increased slightly from 22% to 24%. This was due to the engine acting as a generator, intermittently charging the battery. The ability to switch back to electric mode afterward highlighted the advantages of a plug-in hybrid.
