BYD’s personalized sub-brand Fang Cheng Bao said Thursday that it will officially launch its first sedan lineup, the Formula S series, on September 16.
Fang Cheng Bao announced the launch date on Weibo without providing further details. Final prices for the Formula S sedan and Formula S GT shooting brake will be unveiled at the event.
Both modelsopened for pre-orderson August 20 at pre-sales prices of 230,000 yuan ($33,940) to 280,000 yuan, below the range of 250,000 yuan to 300,000 yuan widely anticipated.
The Formula S series is Fang Cheng Bao’s third product line, following the rugged off-road Bao series and the urban-focused Tai series, and marks the brand’s entry into the sedan market.
The lineup will be the first to feature BYD’s DiSus-M intelligent magnetorheological suspension, according to a media invitation.
The technology uses magnetorheological fluid to adjust damping within milliseconds and was previously used primarily in supercars from brands including Ferrari and Lamborghini.

Bringing the system to models with pre-sales prices starting at 230,000 yuan is another example of BYD’s strategy of making advanced technology more widely accessible.
The Formula S is positioned as a mid- to large-size sedan, measuring 5,060 mm in length, 1,967 mm in width and 1,483 mm in height, with a wheelbase of 2,960 mm. The Formula S GT has similar dimensions and the same wheelbase.
Rear-wheel-drive versions offer peak motor outputs of 245 kW or 300 kW, while the all-wheel-drive version delivers a combined 490 kW.
Battery capacities are 76.744 kWh and 92.093 kWh, offering CLTC ranges of 730 kilometers to 900 kilometers. The entire lineup features BYD’s second-generation Blade Battery and supports flash charging.
The previously announced Formula S family also includes the Formula SL coupe, which has yet to open for pre-orders.
The launch comes as the brand’s sales climb rapidly. Fang Cheng Bao delivered 41,568 vehicles in August, up 155.57% year-on-year, according to data compiled.
The brand said in early August that cumulative sales hadsurpassed 500,000 vehiclesin less than 3 years, with an average transaction price exceeding 223,000 yuan.
