Overview
MAEXTRO (尊界汽车) is a Chinese premium automotive brand associated with Harmony Intelligent Mobility Alliance (HIMA), Huawei’s collaborative smart-car ecosystem. It was developed by JAC Motors and Huawei, bringing together JAC’s vehicle manufacturing capabilities and Huawei’s smart-car technologies and ecosystem. The brand entered public view in 2024 as the highest-positioned marque in HIMA’s multi-brand lineup. The brand’s first announced vehicle is the MAEXTRO S800, a large luxury sedan. The S800 was unveiled in November 2024 and positioned for the upper end of China’s premium-car market. Its role is to establish MAEXTRO as a high-end marque rather than a mass-market line. The offering combines a luxury-vehicle proposition with Huawei-associated intelligent-driving and digital-cockpit technology; vehicle specifications and feature availability depend on the model and configuration. MAEXTRO’s initial market focus is China. It is a young brand, and public information about its corporate structure, standalone leadership, headquarters, and international operations is limited. The brand is linked to JAC and Huawei, but should not be treated as a separately listed company or assumed to be wholly owned by either partner. Its market positioning emphasizes premium status, advanced in-car technology, and the manufacturing and technology collaboration behind the vehicle.
History
MAEXTRO (尊界) emerged in 2024 as a premium automotive marque developed by JAC Motors and Huawei. It is associated with Harmony Intelligent Mobility Alliance (HIMA), the collaborative smart-car ecosystem through which Huawei works with automotive manufacturers. The brand’s creation reflects a partnership model in which a vehicle manufacturer contributes automotive production experience while Huawei contributes smart-car technologies and ecosystem capabilities. Public information does not establish a standalone corporate entity, a sole owner, or a separate founding team for MAEXTRO. The name became publicly associated with HIMA’s high-end offerings during 2024. MAEXTRO was positioned as the most premium marque in the ecosystem’s multi-brand portfolio, distinguishing it from brands aimed at broader market segments. The brand’s initial focus was the Chinese market, and its public identity has centered on premium vehicles combining luxury positioning and connected-car technology. In November 2024, MAEXTRO unveiled the S800, a large luxury sedan and the brand’s first announced model. The model served as the principal expression of the brand’s premium ambitions and as a showcase for the JAC–Huawei collaboration. The S800’s introduction established MAEXTRO’s initial product identity around a flagship sedan rather than a broad range of vehicle categories. As a newly introduced marque, MAEXTRO’s publicly documented history remains short. Its available brand story is principally defined by the partnership, its place in the HIMA portfolio, and the S800 launch. Information about subsequent model expansion, overseas sales, standalone management, or a separate corporate headquarters is not established here and should not be inferred.

Zunjie V800 brake pedal brackets fracture in emergency braking tests
In October 2026, Chinese auto media Dongchedi published a test video reporting that the brake pedal brackets of three Zunjie V800 units physically fractured during 100km/h-0 emergency braking tests, drawing wide attention. That evening, Zunjie Auto issued a statement saying its braking system exceeds national and industry standards, and said it will further optimize the component's design and offer delivered users a free upgrade option.

Zunjie sends users brake pedal test explanation showing V800 samples withstood 3000N without damage[2]
Reported:
On October 13, Zunjie Auto sent users an explanation of brake pedal testing results, disclosing that a third-party testing institution inspected the Zunjie V800 brake pedal on October 11 and that, under a stringent test with longitudinal force increased to 3000N, the tested samples showed no cracks or damage; four samples under standard 1500N load testing were judged to meet the strength requirements of industry standard QC/T 788—2018. The testing was carried out by the testing center of China Automotive Engineering Research Institute Co., Ltd. The disclosure responds to a controversy that began on October 8, when Dongchedi published a test video claiming that three new Zunjie V800 vehicles suffered brake pedal bracket fractures during repeated emergency braking tests from 100 km/h; Zunjie characterized the test as non-standard extreme conditions, while Dongchedi staff said it was normal heavy braking. Zunjie also said it will continue to upgrade the brake pedal to expand safety redundancy.

Zunjie said the previously announced pedal upgrade will still proceed despite the favorable third-party test results, with the stated goal of continuing to expand safety redundancy.
