On July 23, 2025, Huawei Terminal officially announced that the Hongmeng Intelligent MAEXTRO S800 sedan will be the world's first HUAWEI ADS 4 assisted driving system, equipped with a new WEWA technology architecture (World Engine + World Action Model), achieving a technological breakthrough of 1,000 times increase in cloud training difficult case data, 50% reduction in end-to-end latency, and 30% reduction in heavy braking rate. This "era flagship" jointly created by JAC Motors and Huawei entered the ultra-luxury market with a price of RMB 708,000-1.018 million, and won 8,000 large orders within 50 days of its launch.
The MAEXTRO S800 is equipped with an omnidirectional stereoscopic fusion perception system consisting of 36 sensors, including:
1 192-line laser radar + 3 high-precision solid-state laser radars, with a detection accuracy of ≤3cm;
5 4D millimeter-wave radars + 12 ultrasonic radars, with a 40% increase in penetration and recognition distance in rainstorms;
11 high-definition cameras (including 4 surround views + 4 side views), supporting "ghost head" emergency avoidance;
Innovative functions include emergency obstacle avoidance without lane lines, tire burst stability control, negative obstacle correction and other scenarios. Its parking space to parking space pilot assistance 2.0 can realize cross-level parking lot memory cruise.
Huawei's self-developed Tuling Longxing Platform brings three major breakthroughs:
Predictive suspension: AI road pre-aiming system adjusts air suspension 0.5 seconds in advance, and bump filtering efficiency is increased by 60%;
Super maneuverability control: supports 16° crab steering and 5.05-meter minimum turning radius, and completes dual-lane U-turns in one go;
Full-domain redundant safety: dual-chamber air suspension + continuously variable damping shock absorber, body offset after tire burst <0.5 meters;
Space design: 5480×2000×1542mm body, 3370mm wheelbase, first-of-its-kind rear double zero-gravity seats;
Endurance performance: The extended-range version has a comprehensive endurance of 1333km (400km pure electric), and the 800V high-voltage platform supports 10.5-minute fast charging;
Safety protection: The torsional stiffness of the Xuanwu body structure reaches 53300N·m/deg, and the side top bears 16 tons of pressure;
The launch of MAEXTRO S800 marks the first time that a Chinese brand has achieved a comprehensive surpassing of traditional super luxury cars in the three dimensions of intelligent driving, digital chassis, and active safety. Yuchengdong, chairman of Huawei Terminal BG, said that this is not only a technological breakthrough, but also the "beginning of China's smart manufacturing moving towards high-end". With the start of the first batch of user deliveries in July, this "mobile technology fortress" is redefining the value standard of million-level luxury cars.
