What BYD’s Two-Door Microcar Patent Shows

BYD has been granted a design patent for a two-door microcar, offering fresh clues to its small-car design direction. The China National Intellectual Property Administration (CNIPA) published the document on November 10, 2026. The patent images show a rounded, compact body with one large door on each side, short front and rear overhangs, and wheels positioned close to the corners.

Wolfgang Egger: The Designer Behind BYD’s Microcar Patent

Wolfgang Egger previously headed Audi Group design, responsible for both Audi and Lamborghini. He joined BYD in 2017 and led the team behind the Seagull electric hatchback and Han sedan. He also introduced BYD’s “Dragon Face” and “Ocean Aesthetics” design languages. CnEVPost calls him BYD’s global design director. Co-designer Zhao Binggen heads BYD’s Dynasty Research Institute.

BYD Co., Ltd: The Company and Group Behind the Filing

BYD Co., Ltd, listed in Hong Kong (HKEX: 1211) and headquartered in Shenzhen, is the patent holder. The sources do not name a separate parent company above it. Its brands referenced in the coverage include Dynasty, Ocean, Fang Cheng Bao, Yangwang and Denza. BYD marked its 19 millionth new energy vehicle (NEV) a day before the patent news, a Fang Cheng Bao model.

What the Patent Does Not Confirm: Powertrain, Size, Seats and Launch

A design patent protects appearance, and this filing lists shape as the key design point. It gives no model name, dimensions, seating capacity or powertrain. The images alone therefore cannot establish whether the vehicle would be all-electric or reach production. No battery, voltage, charging or inverter data appears in the filing, so any range or high-voltage claim would be speculation. BYD has not confirmed production plans.

How BYD’s Microcar Design Compares with the Smart #2 and Seagull

CnEVPost says the design resembles the Smart #2, from the Mercedes-Benz and Geely joint venture, the all-electric successor to the two-seater ForTwo. Smart #2 Premium launched in China at a limited-time 99,900 yuan ($14,880) after incentives. The Seagull, BYD’s smallest model, looks markedly different. Its second generation launched on October 20, growing 425 mm to 4,205 mm and moving from four seats to five.

BYD’s 2026 Small-Car Moves: Racco, X-PACK and Seagull Gen 2

BYD launched the all-electric kei car Racco in Japan on July 28. Nikkei’s Chinese-language site reported on August 31 that BYD planned to use Racco’s X-PACK technology to develop small EVs for Europe and other markets. X-PACK integrates electrical components, such as the inverter, into the battery pack to free interior space. No source links X-PACK to this patent.

China’s Sub-$8,000 Micro-EV Benchmark a BYD Microcar Would Face

BYD has yet to enter the microcar market. As our report on China’s cheap micro-EV ecosystem explains, rivals build low-cost LFP four-seaters priced roughly $6,000 to $8,000:

• Wuling Hongguang Mini EV: ¥40,800–54,800; 16.2–25.1 kWh LFP; 205–301 km CLTC.
• Changan Lumin (long-range): ¥53,900; 28.1 kWh LFP; 301 km CLTC.
• Chery QQ Ice Cream: ¥40,900–49,900; 17.3 kWh LFP; 220 km CLTC.
