BYD Reveals Formula X Electric Convertible With Supercar Doors
Watch Your Back, MG Cyberster
For a while now, the MG Cyberster has been sitting in a pretty unique spot. It's one of the few true electric roadsters on sale today, and more importantly, one of the only proper two-seat EV convertibles. Now, it looks like it may finally have a serious rival.
BYD introduced the Formula X at Auto China 2026, a two-door convertible from its newer performance brand, Fang Cheng Bao. Where the MG Cyberster feels closer to a grand tourer, the Formula X is clearly targeting a more exotic, supercar-like experience.
Fang Cheng Bao is a recent addition to BYD's lineup, launched in 2023 after brands like Dynasty, Ocean, Denza, and more famously, Yangwang. It started out focused on rugged SUVs and lifestyle vehicles, but the Formula X signals a clear move into performance cars.
Built Like a Show Car, Headed for Production
The Formula X borrows a lot from the Fang Cheng Bao Super 9 concept, following the brand's current design language. It sits low and wide, with proportions that are unmistakably supercar-inspired. The brand calls it a 'golden ratio' silhouette and a 'hunting leopard' stance, which, while dramatic, does match the overall look.
Up front, the "Sharp Leopard Eye" headlights give it a very aggressive face, while the body itself is packed with aero details. There are 19 separate air vents spread across the exterior, along with large diffusers, sculpted side sections, and an active electric rear spoiler. At the back, the "Infinite Ring" taillights keep things futuristic without looking overly complicated.
A full carbon fiber body helps keep weight down and shows that the Formula X is more than just a design study. The doors are a mix between gull-wing and scissor styles, adding some visual drama.
Global Ambitions
Inside, the Formula X is designed as a true driver's cockpit, and it avoids the trend of replacing everything with oversized touchscreens.
The cabin features a wraparound layout in gray and green, with physical buttons, integrated sports seats, a retractable steering wheel, and a four-point harness. The setup feels more suited to the track than to casual city driving.
BYD plans to start production and sales of the Formula X next year. For now, Fang Cheng Bao is focused on China and a few international markets – probably including Canada – with no signs that the Formula X will be offered in the US. Regulations, pricing, and BYD's lack of a US dealer network make that unlikely.
