Leaked images also reveal its interior. Earlier, BYD applied for sales licenses for the Formula S liftback and Formula S GT wagon, preparing for a Q3 2026 launch. Launched in China in 2023, Fang Cheng Bao (FCB) was BYD’s dedicated off-road sub-brand. In 2024, it announced new sports cars and sedans, then unveiled the Formula X concept car at the 2026 Beijing Auto Show. Both the S liftback and S GT wagons debuted on June 11, when FCB’s sale licenses with China’s Ministry of Industry and Information Technology (MIIT) were announced. Meanwhile, recent spy shots show the Formula S sedan in light camouflage, with unpainted bumpers and minimal vinyl, suggesting near-production status. What’s new with the FCB Formula S The lightly-camouflaged Formula S, and its MIIT listing. The images show the sedan equipped with a roof-mounted LiDAR unit, and it’s expected to come with BYD’s DiPilot 5.0 assisted-driving system. Its badging has been covered up, but its rims match those filed by FCB in the MIIT application. Leaked images of the interior of the Formula S. Turning to the interior, the images were likely taken by insiders at the 2026 Beijing Auto Show. The photos show a velvet red interior and a steering wheel embossed with FCB’s logo. The front seats have side bolsters but do not appear particularly sporty. More on the FCB Formula S and Formula S GT The Formula S and S GT are FCB’s first sedans and wagons, both featuring a design language similar to that of the Denza Z sports car. Aero touches such as front splitters and rear diffusers are present, and both cars share a taillight design that recalls FCB’s logo. The exterior of the Formula S liftback sedan.

The wheelbase sits at 2,950 mm for both. The exterior of the Formula S GT Wagon. Source: MIIT The S sedan is slightly lighter on the scales, with a curb weight of 1,999-2,250 kg. In contrast, the S GT wagon’s increased interior volume gives it more heft, raising its curb weight to 2,170-2,280 kg. Expanding on performance, the S sedan gets a 245 kW (329 hp) rear motor for its entry-level RWD trim, with a peppier 300 kW (402 hp) rear motor for the mid-level RWD trim. The RWD entry-level S GT wagon also gets the 245 kW (329 hp) rear motor, and both cars get a 490 kW (657 hp) twin-motor system for the top AWD trim. Battery details remain undisclosed, but both models are set to feature BYD’s Blade Battery 2.0 and Flash Charging. CarNewsChina has also indicated that Formula S and S GT are poised to enter international markets under the Denza brand, consistent with current FCB models.

The brand is enjoying great success in China, with consistent year-on-year growth for the past 12 months. FCB’s current lineup consists solely of off-road SUVs, though, and the Formula S and S GT will help diversify it. Source: Di Fen Zhi Jia, Di Wang
