The Eado HEV starts at 79,900 yuan (11,760 USD) under promotional pricing, while the CS75 Plus HEV starts at 109,900 yuan (16,180 USD). Both models combine combustion engines with high-output electric motors and 1.7 kWh lithium-ion battery systems. Narrowing cost gap The Eado HEV uses a 1.5-litre naturally aspirated engine producing 72 kW paired with a 160 kW electric motor. The CS75 Plus HEV uses a 1.5-litre turbocharged engine rated at 110 kW paired with a 180 kW electric motor. Both models use a shared 1.7 kWh battery architecture, with differences in system output driven by motor tuning and engine configuration rather than by battery capacity. Crossover by 2027 The Eado HEV reports a claimed urban fuel consumption of 2.98 L/100 km under typical driving conditions. The CS75 Plus HEV integrates a higher-output hybrid configuration with a 20,000-rpm motor. Both vehicles use Changan’s BlueCore hybrid control architecture with regenerative braking and dedicated hybrid transmission systems.

The Eado HEV uses a dual-screen configuration with a 10.25-inch instrument cluster and a 14.6-inch infotainment display. Both models integrate TianShu OS with DeepSeek-based voice interaction capabilities and include driver-assistance features such as highway assist and automated parking. BlueCore hybrid system powers Changan’s new CS75 Plus and Eado HEV models. Industry push China’s hybrid vehicle segment has expanded alongside plug-in hybrid and battery-electric platforms, with multiple manufacturers introducing new HEV architectures in 2026. Hybrid system development across the industry continues to focus on improving thermal efficiency and reducing fuel consumption under standardised test conditions and in real-world use cases. In March 2026, Changan unveiled its next-generation BlueCore hybrid engine, featuring a claimed 44.28% peak thermal efficiency and, the company said, the industry’s first 500-bar direct-injection system for a production hybrid engine. The architecture also introduced a P1+P3 hybrid layout, AI-based energy management, and a 1.7 kWh battery system shared with the newly launched Eado HEV and CS75 Plus HEV models. Policy backdrop Hybrid systems remain part of China’s multi-pathway electrification framework alongside BEV and PHEV development. HEVs are positioned within internal combustion efficiency improvement strategies during transition phases. Sales backdrop Changan’s domestic sales reached 30,686 units in April 2026, down 51.0% year-on-year and 34.6% from March, according to China EV DataTracker data. The company’s domestic market share stood at 2.2% in the month, down from 2.9% in March. Changan sales in China. Credit: China EV DataTracker
