GAC Unveils Five Core Technologies: Xingyuan PHEV Achieves 3L/100km Fuel Efficiency, Hyper GT Climbing Edition Launches in May

At GAC Tech Day 2026, GAC Group unveiled five core technologies spanning powertrain, body structure, intelligent cockpit, electronic/electrical (E/E) architecture, and automotive-grade chip ecosystems. **Powertrain:** GAC introduced the "Stellar Power" technology brand, comprising two systems: Stellar Plug-in Hybrid and Stellar Super Dual-Motor Hybrid (HEV+). The Stellar Plug-in Hybrid features a 1.5T hybrid engine delivering a maximum output of 125 kW and peak torque of 245 N·m, paired with the GMC 3.0 hybrid transmission. It comes in two variants—Thunder Edition and Gale Edition. The Thunder Edition enables mid-to-large SUVs to achieve 0–100 km/h acceleration in under 4 seconds, with a total wheel-end torque of 10,000 N·m from its all-wheel-drive system, capable of climbing gradients up to 70% (approximately 35°). The Gale Edition weighs just 98.5 kg, making it China’s first mass-produced dual-motor hybrid transmission under 100 kg, with a peak mechanical efficiency of 98.65% and an electronic control efficiency of 99.2%. Vehicles weighing around 2 tons equipped with this system achieve fuel consumption of approximately 3 L/100 km. The Stellar Super Dual-Motor Hybrid integrates a 5.4 kWh high-rate safety battery with a peak discharge power of 150 kW—87.5% higher than the previous generation—enabling over 17 km of pure electric driving at low speeds. It also supports in-vehicle entertainment, 2.2 kW vehicle-to-load (V2L) power output, 12-hour Sentry Mode, and full-vehicle OTA updates—all without consuming any fuel. Under CLTC conditions, compact sedans achieve energy consumption of about 2 L/100 km, while a 2.1-ton, seven-seat mid-size MPV consumes roughly 3 L/100 km. Stellar Power has undergone 10 million km of equivalent validation and extreme-environment testing, with the Stellar Plug-in Hybrid earning the title of “World’s Top 10 Hybrid Power Systems.” **Body Structure:** GAC launched the "Starship Body," featuring a closed-loop torsion-resistant structure combining an embedded full-length frame rail and a multi-ring cage design. This includes front-to-rear high-strength embedded frame rails, a protective framework composed of 5 longitudinal and 13 transverse high-strength steel members, and a hidden anti-roll bar integrated into the A-pillar. The body achieves a torsional rigidity of 38,000 Nm/°—about four times that of traditional rugged off-road benchmarks—and a bending rigidity of 42,000 N/mm, 1.5 times the industry average. Critical areas utilize 2,000 MPa hot-stamped steel, while the A-pillar employs a 2,200 MPa hot gas-forming tube beam capable of withstanding roof crush loads of 12.2 tons—2.7 times the national standard requirement. This body structure has completed over 600 simulation iterations, more than 3,000 hours of bench testing, and over 1 million km of real-world all-terrain road testing. **Intelligent Cockpit:** GAC unveiled the "Galaxy Intelligent Cockpit ADiGO Intelligence" system, built on an edge-cloud integrated architecture powered by a multimodal large AI model. End-to-end response latency is under 1.6 seconds, with in-cabin object recognition accuracy exceeding 95%. The system features a memory-based multi-agent collaborative engine capable of coordinating up to 15 AI skills simultaneously, enabling end-to-end services such as route planning, restaurant queuing, and parking reservations. It can also detect occupant emotions in real time and proactively engage users through synchronized audio, lighting, visuals, and an AI companion avatar. Equipped with a long-term memory engine, the system learns personalized user preferences—including travel routines and seat positions—and is scheduled for gradual deployment across GAC models starting Q3 2026. **Electronic/Electrical Architecture:** GAC introduced the "Stellar E/E Architecture 4.0," featuring a domain-fused central computing platform powered by a 3nm flagship chip. Its comprehensive intelligent performance is 40% higher than the previous generation, marking the industry’s first integration of six domains—autonomous driving, intelligent cockpit, powertrain, chassis, body, and connectivity—into a single computing center, achieving the highest level of integration in the industry. Communication bandwidth has increased fivefold, cross-domain coordination response time has been reduced to 2 ms, and full-vehicle OTA update duration has been shortened from 30 minutes to just 8 minutes. This architecture supports advanced autonomous driving and complex intelligent cockpit functions and enables data interoperability with Haier’s UhomeOS, facilitating a seamless "human-vehicle-home" connected ecosystem. **Automotive-Grade Chip Ecosystem:** GAC announced that the Hyper GT Summit Edition will launch in May 2026, becoming China’s first intelligent new-energy vehicle with 100% domestically designed chips. The vehicle integrates 1,004 chips throughout, all sourced from Chinese suppliers. It features the "Hanyu" M1 SoC—a central computing platform co-developed by GAC and ZTE Microelectronics—offering high computing power, rapid data transfer, and robust security. GAC has partnered with 105 ecosystem players—including Horizon Robotics, Hua Hong Semiconductor, Silan Integrated, and Rockchip—to jointly define, develop, and validate nearly 400 automotive-grade chips.
