Overview
Rox Motor is a Chinese automotive company headquartered in Shanghai and focused on electrified sport utility vehicles. The company was founded in 2021 by Zhang Jin, the entrepreneur behind Roborock, a vacuum-cleaner and home-robotics company. Rox Motor was established with financial support from Xiaomi, and its stated development direction centered on high-technology vehicles using electrified powertrains and aluminum-intensive construction. The company entered the market under the names Polestones Automobile, Polar Stone, and Jishi before the Rox Motor identity was introduced more prominently in 2024 and subsequently expanded into overseas markets. During its first year, Rox Motor reportedly recruited approximately 1,800 employees. It also established technology-cooperation arrangements with major automotive and component suppliers, including Bosch, CATL, Continental, and Valeo. These relationships covered the technical and industrial capabilities needed to develop an advanced vehicle despite Rox Motor being a new entrant to automobile manufacturing. BAW participated in the development and production of the company's first vehicle through a technology-cooperation agreement. The company's first production model was the Rox 01, a mid-size sport utility vehicle using an extended-range electric powertrain. Initial prototype testing began in November 2022, and Rox Motor released technical information about the vehicle in June 2023. The model was formally presented in August 2023 at the Beijing Auto Show. It was announced for production by Polestones Automobile, described as a division or operating identity associated with Rox Motor. Serial production began in late October 2023 under the cooperation arrangement with BAW, with customer deliveries starting in November 2023. Rox Motor's product strategy combines electric-drive technology with an onboard combustion engine used as a range extender, a configuration intended to reduce the range limitations associated with battery-only vehicles while retaining electric propulsion for normal driving. The brand's initial emphasis has been on relatively large SUVs rather than small urban cars or mass-market sedans. The Rox 01 is positioned as the core product, while the Rox Adamas, introduced for 2025, is described as a larger and more luxurious extended-range SUV derived from the same general product direction. International expansion began in 2025. The Rox Motors brand was introduced first in the Middle East and was later extended to Africa and Central Asia. This expansion indicates an effort to establish the company outside mainland China through markets where larger SUVs and range-flexible electrified vehicles may have strong appeal. In Oman, the brand received the 2025 Most Trusted Brand award in the electric-vehicle category. Publicly available reference material does not establish Rox Motor as a listed company, does not identify a separate parent company, and does not provide a confirmed official corporate website or detailed current executive roster. Its present business is therefore best characterized as an active, privately held Chinese vehicle manufacturer with a developing international distribution footprint.
History
Rox Motor was established in Shanghai in 2021 by Zhang Jin, who had founded Roborock, a company known for vacuum cleaners and home-robotics products. With support from Xiaomi, Zhang Jin directed investment toward creating a new automotive business. Rox Motor's initial ambition was to develop electrified, high-technology vehicles, including vehicles designed around aluminum construction. The company entered a sector dominated by established global manufacturers and rapidly expanding Chinese electric-vehicle producers, so it adopted a partnership-based development model rather than building every engineering and manufacturing capability independently. The company expanded quickly in its first year, reportedly hiring about 1,800 people. It signed technology-cooperation agreements with Bosch, CATL, Continental, and Valeo, bringing together expertise in automotive systems, batteries, electronics, and components. BAW also became involved in the development of Rox Motor's first vehicle and later supported its production. These arrangements allowed Rox Motor to move from startup formation to vehicle engineering and manufacturing on a relatively short timetable. Prototype testing for the first model began in November 2022. In June 2023, Rox Motor published initial technical information about the vehicle, which was subsequently identified as the Rox 01. The model was officially unveiled in August 2023 at the Beijing Auto Show. At launch, the vehicle was associated with Polestones Automobile, an operating identity or division used by Rox Motor. Earlier references also used the names Polar Stone and Jishi, while the Rox Motor name became the principal international-facing brand as the company developed its overseas business. The Rox 01 entered serial production in late October 2023 under a technology-cooperation agreement with BAW. Deliveries began in November 2023, giving Rox Motor its first commercial vehicle. The Rox 01 is a mid-size SUV powered by an extended-range electric system. Rather than relying solely on a large battery, this type of drivetrain uses electric propulsion together with an engine that can generate electricity or extend usable driving range. The configuration reflects Rox Motor's attempt to combine the driving characteristics of an electric vehicle with greater long-distance flexibility. Rox Motor continued its SUV-led product strategy with the Rox Adamas, identified as a 2025 full-size extended-range SUV and a luxury version of the Rox 01. The model broadened the brand's offering toward a larger and more upscale vehicle segment. Available reference material does not provide a full technical specification history, detailed trim structure, or confirmed production volumes for either vehicle, so the brand's product record is best described at the model and powertrain level. In 2025, Rox Motors began introducing its brand outside China. The first overseas focus was the Middle East, followed by expansion into Africa and Central Asia. This sequence positioned the company in regions where large SUVs are commercially important and where extended-range vehicles can offer an alternative to fully battery-electric models in markets with differing charging infrastructure. Rox Motors subsequently received an award in Oman naming it the country's Most Trusted Brand in the electric-vehicle category for 2025. Rox Motor remains an active private automotive company. The available material does not identify a stock exchange listing, a separate corporate parent, a confirmed official website, or a comprehensive list of current executives. It does, however, establish a clear development path: startup formation in 2021, rapid supplier and engineering partnerships, prototype work in 2022, public unveiling and commercial production of the Rox 01 in 2023, brand consolidation and overseas expansion by 2025, and continued development of larger extended-range SUVs.
