BYD's Fang Cheng Bao schedules Sept 16 debut for its first sedan family, the Formula S series

Fang Cheng Bao, BYD's personalization-focused sub-brand, has locked in September 16 as the official launch date for its first sedan line, the Formula S series, with the event set to reveal final pricing for the Formula S sedan and the Formula S GT shooting brake. Since pre-orders opened on August 20, the pair have carried pre-sales tags of 230,000 to 280,000 yuan (roughly $33,940) — undercutting the 250,000-300,000 yuan window most observers had forecast.

The series becomes the brand's third product family, slotting in beside the off-road-oriented Bao line and the city-oriented Tai line. It will also be the first to carry DiSus-M, BYD's magnetorheological adaptive suspension — a technology that tunes damping within milliseconds via magnetorheological fluid and had previously been the preserve of supercars from the likes of Ferrari and Lamborghini. Offering it on a car from 230,000 yuan fits BYD's established pattern of pushing high-end hardware into cheaper segments.

Under the skin, the mid-to-large Formula S measures 5,060 mm long with a 2,960 mm wheelbase, which the GT shares. Rear-drive trims offer 245 kW or 300 kW motors, while the all-wheel-drive variant combines for 490 kW. Two second-generation Blade Battery packs, at 76.744 kWh and 92.093 kWh, support flash charging and span 730-900 km of CLTC range. A Formula SL coupe rounds out the family but has not yet begun taking orders.

The rollout arrives on strong momentum: the brand shipped 41,568 vehicles in August, up 155.57 percent year-on-year, and disclosed in early August that cumulative deliveries had topped 500,000 in under three years at an average transaction price above 223,000 yuan.
