BYD's Fifth Generation DM Technology and the Launch of Qin L DM-i and Seal 06 DM-i
On May 28th, BYD held an event in Xi'an to announce the launch of its fifth-generation DM (Dual Mode) technology along with two new models, the Qin L DM-i and Seal 06 DM-i. This new technology achieves the world's highest engine thermal efficiency at 46.06%, the lowest fuel consumption at 2.9L per 100 kilometers, and the longest comprehensive range at 2100 kilometers. These milestones set a new global standard for fuel efficiency, marking the beginning of the "2.X L per 100 km" fuel consumption era.
Immediate Production and Delivery
The first models to feature the fifth-generation DM technology are the Qin L DM-i and Seal 06 DM-i, both of which are now available for purchase and delivery. These models come in five different versions. The two new plug-in hybrid models offer fuel consumption that is one-third of traditional gasoline vehicles and a range that is three times longer, providing users with an exceptional and worry-free driving experience.
Innovative Three Architecture Systems
The fifth-generation DM technology, with its "fast, economical, quiet, smooth, and green" advantages, sets a new benchmark for plug-in hybrid technology. This is due to its electric-centric power architecture, all-temperature vehicle thermal management architecture, and intelligent electrical and electronic architecture.
Electric-Centric Power Architecture: This includes a high-efficiency engine specifically designed for plug-in hybrids, achieving a world-leading thermal efficiency of 46.06%. The EHS electric-hybrid system features an optimized structure, increasing power density by 70.28% and reducing energy flow path losses, achieving a comprehensive efficiency of 92%. The blade battery, designed for plug-in hybrids, increases energy density by 15.9%, ensuring robust power supply.
All-Temperature Vehicle Thermal Management Architecture: This system is elevated to the same level of importance as the power architecture. It integrates front cabin thermal management, battery thermal management, and cabin thermal management, working together to minimize energy consumption. This architecture can save up to 10% energy in high-temperature environments and up to 8% in low temperatures, ensuring both efficiency and comfort.
Intelligent Electrical and Electronic Architecture: This includes the industry's first seven-in-one domain controller for plug-in hybrids, enhancing functional reuse and increasing power density by 18.3%. The industry-first chip integration merges the VCU (Voltage Control Unit) and dual MCUs (Motor Control Units) into a three-brain unit, boosting chip computing power by 146%, significantly improving overall vehicle integration and performance.
Immediate Market Availability
The Qin L DM-i and Seal 06 DM-i lead the way in the mid-sized vehicle segment, marking the start of the "2L per 100 km" fuel consumption era. From fuel economy to technology, design, space, driving experience, intelligence, and safety, these models offer a revolutionary new standard for the automotive industry.
