FCB is currently a China-only brand, and the Formula S is strictly China-only at the time of writing. So why is it coming for the Model 3? Simple: China remains Tesla's most important international market.

Having established that, let's take a look at what the sedan offers. The Formula S comes in a total of nine variants: five sedans and four GT models. And considering FCB is a BYD sub-brand, all of these trims come equipped with BYD's Blade Batteries and Flash Charging system. That same tech is claimed to charge the battery from 10 to 70% in just around five minutes. And 10 to 90% in about nine minutes.

The standard, base-trim Formula S comes with a 76.744-kWh lithium iron phosphate (LFP) Blade Battery that offers a CLTC range of up to 453 miles (730 km). All the rest of the variants feature a larger 92.093-kWh battery.

The long-distance trim offers a range of up to 559 miles (900 km). Meanwhile, the Formula S all-wheel drive offers around 466 miles (750 km) of CLTC range. Finishing the lineup are the GT variants – the RWD trim coming with a CLTC range of up to 528 miles (850 km) and the AWD GT offering 453 miles (730 km).

As for power, the rear-wheel-drive Formula S variants deliver peak power of 329 hp or 402 hp, while the rear-wheel-drive Formula S GT produces 402 hp. Meanwhile, the all-wheel-drive trims offer a combined output of 657 hp.

It also comes equipped with the LiDAR-equipped God's Eye B driver-assistance system, which supports automated parking and urban and highway navigation aid. Crazy, right?

What's even crazier is that people can choose between DiSus-A and DiSus-M trims. DiSus-A (Intelligent Air Body Control System) uses air springs instead of traditional coil springs. This system basically helps raise or lower the vehicle body by up to 5.9 inches (150 mm) for ground clearance or easy entry.

Meanwhile, the DiSus-M (Magnetorheological Fluid Damping System) uses magnetorheological (MR) fluid dampers instead of air chambers. While it doesn't change the vehicle's physical ride height, it mainly improves the vehicle's response to the environment, thanks to a reaction time of merely milliseconds.

The Formula S is 199.2 inches (5,060 mm) long, 77.4 inches (1,967 mm) wide, and 58.4 inches (1,483 mm) tall. That means it's noticeably bigger than the Tesla Model 3. Meanwhile, the GT comes with a length of 197.8 inches (5,025 mm). Clearly, it's no compact sedan – it's actually the same size as European executive saloons.
