Market Sales Recommendation for BYD472Q Series Engine
"Redefining Efficiency, Empowering the Future – BYD472Q Engine: Pioneering Green Mobility"

Dear Partners/Dealers/Industry Colleagues,

As the electric vehicle revolution reshapes the automotive landscape, high-efficiency powertrains have become the cornerstone of industry competitiveness. BYD proudly introduces the BYD472Q Series Engine (comprising the iterative models BYD472QA and BYD472QC), a cutting-edge solution for plug-in hybrid electric vehicles (PHEVs). With "Unparalleled Thermal Efficiency, Ultra-Low Fuel Consumption, and Unmatched Reliability", this engine sets a new standard for the industry. Here's why it deserves your attention:

1. Technological Breakthroughs: Industry-Leading Performance

Record-Breaking Thermal Efficiency:
The BYD472QA achieves 43.04% thermal efficiency, while the upgraded BYD472QC pushes this to 46.06% – the highest in量产 engines. Enabled by Atkinson Cycle technology, intelligent combustion systems, and high tumble air ducts, it delivers NEDC fuel efficiency as low as 3.8L/100km, slashing long-term ownership costs.

Dedicated Hybrid Optimization:
Engineered for BYD's DM-i Hybrid System, it integrates EGR, split cooling, and low-friction designs, ensuring seamless transitions between electric and combustion modes. This enables +1,245km total range (full tank + full battery), eliminating range anxiety.

Robust Durability:
Aluminum alloy construction and rigorous extreme-condition testing guarantee longevity. Backed by BYD's reputation for "technology-driven" quality, it minimizes maintenance costs.

2. Market Competitiveness: Cost-Effective Edge

Outperforming Competitors:
Compared to Honda i-MMD and Toyota THS, the BYD472Q offers higher efficiency and lower costs, meeting urban and long-distance needs with unmatched versatility.

Broad Vehicle Compatibility:
Proven in bestsellers like the Qin PLUS DM-i, Song PLUS DM-i, and Hai Bao 06 DM-i, it caters to compact cars and SUVs, driving monthly sales exceeding 30,000 units.

Policy-Driven Growth:
Compliant with China VI emissions standards, it qualifies for up to CNY 35,000 government subsidies (2025), boosting consumer adoption.
