The Thor EM-i Super Electric Hybrid is developed by Geely based on a high-performance electric hybrid technology system, integrating global power and AI technology to offer a new generation of ultra-efficient super electric hybrid for mainstream market users.
With a thermal efficiency of 46.5%, the dedicated engine for the Thor Super Electric Hybrid is the highest among mass-produced gasoline engines worldwide. The test vehicle equipped with the Thor EM-i Super Electric Hybrid has an extreme range of up to 2,390.5 kilometers, with an average fuel consumption of 2.62 liters per 100 kilometers.
The Thor EM-i Super Electric Hybrid is the world’s first to feature a silicon carbide boost module, achieving stable boosting through all-range multi-voltage optimization, and simultaneously upgrading the P3 motor power to 160 kW, paired with the special battery for hybrid electric driving, providing a seamless driving experience in both full charge and discharge states.#### Engine Thermal Efficiency 46.5%
Thunder Super Hybrid Special Engine continues the Thunder Yufeng Combustion System’s design philosophy of “airflow priority, wind-driven, conforming to the trend.” Unique designs such as the “duckbill” large-inclination air passage, Mask structure air guide, and airflow contour piston top decompose in-cylinder airflow motion into four stages: production, transportation, transformation, and utilization, leading to efficient system control.
Based on the physical boundaries of airflow design and coupled with an inclined squeeze combustion chamber structure, the combustion speed increases by more than 20%, with compression ratio precision improved by 35%, achieving optimal combustion to the maximum extent. The dual-channel integrated exhaust design makes exhaust smoother, increasing power by 4%. The engine’s high-efficiency area coverage is relatively 56% higher than the previous generation and improves by 15.2% in absolute value.
PCM maximum efficiency is 99%. SiC stepless variable voltage module efficiency is 99.9%. Multi-voltage optimization across all domains, with stable boosting, provides consistent performance whether charged or depleted, enhancing inductive experience.
The motor utilizes the dual-end X-Pin flat wire winding process, achieving a maximum efficiency of 98.02%. An industry-first integrated rotor shaft: the gear and motor shaft form a single piece, reducing fit tolerance accumulation, enhancing gear precision, and optimizing NVH. The segmented design of the V6 stage reduces eddy current loss in magnets, improving motor efficiency. Highly precise oil spray cooling technology boosts heat exchange efficiency by 20%, improving temperature uniformity by 18%.
Through intelligent control of the rotational speed and torque between the P1 and P3 motors and the engine, a smooth power response is achieved, effectively addressing the challenge of balancing smooth torque transmission and responsiveness, thereby providing a comfortable driving experience. At medium to low vehicle speeds, prioritize pure electric or series mode to maximize the P3 motor’s performance advantages. At high vehicle speeds, utilize parallel control, with engine drive as primary and motor assistance for adjustment, enhancing power output and engine direct-drive fuel-saving benefits. Multi-layer intelligent energy management and SOC hierarchical control strategies ensure efficient battery reserve to meet electric drive demands.
Geely globally pioneers the “Universal Safety Concept,” expanding automobile safety technology from traditional road traffic safety to a broader scope of “universal safety,” encompassing nine major safety systems, including active and passive safety. Thunder EM-i Super Hybrid ensures driving safety without losing control and guarantees reliability and stability even in depleted states through redundant patented technology and ultra-high-standard testing.
The world’s first hybrid safety redundancy patented technology, with the engine, P1 motor, and P3 motor serving as backups for each other. If any component fails, the power system can still drive normally. When the engine is not functioning, the power battery + P3 motor drives the vehicle. When the P3 motor is not functioning, the engine + P1 motor can continue to drive, ensuring no power loss leads to vehicle stalling. The Shamrock Battery’s 5-tier redundancy algorithm employs corresponding protection strategies at each level, preventing extreme battery under-voltage from causing power loss, thus allowing the vehicle to continue operating normally.#### AI-Enhanced Hybrid Generation
Thor EM-i Super Electric Hybrid integrates AI technology into the power domain, making the system smarter for a worry-free user experience. With Geely’s exclusive integrated cloud-based intelligent network as the foundation, it seamlessly combines real-time sensory data with travel big data. Utilizing the powerful computing capabilities of Geely’s Star Intelligent Computing Center, it deploys AI predictive and decision algorithms to deliver new experiences in smart energy management, smart motion control, and smart cloud diagnosis.
The dedicated AI model analyzes environmental information sensed by the vehicle, driving behavior, navigation data, and road conditions to make comprehensive and intelligent decisions, enhancing the vehicle’s energy management, motion control, and diagnostic capabilities.
Moreover, smart energy management makes intelligent decisions on Thor Intelligent Hybrid’s fuel-electric strategy, battery heating and cooling, target state of charge, and charging reminders based on navigation information, usual routes, ambient temperatures, road conditions, charging habits, and charging maps. It achieves highly personalized energy consumption control, moving beyond the conventional rule-based hybrid strategies that rely on preset parameters like target state of charge and speed.
