BYD Granted Design Patent for Two-Door Microcar
In this article (3)
China’s intellectual property regulator has granted BYD a design patent for a two-door microcar, publishing grant number CN 310308323 S on Tuesday, November 10, 2026. The approval reveals a rounded, compact body featuring one large door on each side, short front and rear overhangs, and wheels positioned close to the corners.
BYD originally submitted application 202530748612.8 on December 18, 2025. The filing lists five designers, including global design director Wolfgang Josef Egger, but withholds powertrain specifications, exterior dimensions, seating capacity and commercial production plans.
Official documents identify the model as a vehicle intended for passenger transportation, highlighting its silhouette as the primary protected asset. By securing rights to this ultra-compact shape, the automaker creates a potential competitor to the Smart #2, which the Mercedes-Benz and Geely Auto joint venture launched in China with promotional pricing starting at 99,900 yuan ($14,880).
Design Details from the National Patent Registry
Drawings released by the China National Intellectual Property Administration show identical horizontal lighting bands across the nose and tail. Underneath those light bars, curving bumper contours form a distinct lower profile. The design breaks completely from the angular exterior used on the Seagull, which has served as the baseline budget model across BYD dealership networks in mainland China.
The patent images show flush glazing, tight approach angles, and a steeply raked windscreen designed to maximise interior cabin room over a shortened floorpan. Regulators approved the registration purely on aesthetic shape characteristics. Because the agency evaluates form rather than mechanical layout, the registry entry provides no confirmation on whether the platform relies on pure battery propulsion or enters assembly lines unchanged.
“A week ago, Smart broadened showroom pressure by introducing the Smart #2 Premium Edition at a promotional entry price of 99,900 yuan.”
Direct Target on Urban Microcars
The compact proportions place the design in direct competition with the Smart #2, the battery-powered two-seater successor to the ForTwo rolled out by the Mercedes-Benz and Geely Auto joint venture. Smart debuted its production version at the Paris Motor Show on October 12, pricing the initial Gold Couture Edition in China at 112,999 yuan, or about $16,820. A week ago, Smart broadened showroom pressure by introducing the Smart #2 Premium Edition at a promotional entry price of 99,900 yuan.
By sketching out an entry in this ultra-short wheelbase category, BYD signals intent to challenge higher-margin fashion-led city runabouts rather than basic commuter fleet models. The design targets younger metropolitan drivers who navigate cramped parking structures and dense shopping districts, where conventional four-metre hatchbacks prove unwieldy. The financial gamble sits in domestic retail appetite: sub-compact city cars often yield wafer-thin profit margins unless platform volumes scale rapidly across export territories.
Small Vehicle Portfolio Expansion
The patent publication follows a major repositioning across BYD entry-level showrooms. Management enlarged the second-generation Seagull on October 20, stretching the vehicle length by 425 mm to 4,205 mm while converting the rear bench to seat five passengers instead of four. That upward push created a distinct gap at the base of the lineup, leaving space for a dedicated two-door urban runabout below four metres.
International expansion has already tested the small-format waters. BYD introduced the Racco on July 28, selling the purpose-built pure electric model straight into Japan’s regulated kei car category. That release verified consumer reception for sub-compact footprints in Asia’s most congested metropolitan transport hubs.
Engineering work behind these micro platforms is also slated for long-distance export. Technical disclosures in late August detailed plans to adapt the Racco’s X-PACK architecture for European showrooms and other overseas distributors. The packaging method bundles the power inverter and ancillary electrical controls directly into the primary battery enclosure, stripping out redundant sub-assemblies to recover legroom and storage inside cramped vehicle cabins.
BYD must now decide whether to commit factory floor space to production tooling for the two-door concept, with commercial viability tied to pricing below the 99,900 yuan barrier established by rival offerings in Chinese showrooms.
