BYD Fang Cheng Bao Formula S and GT: what Chengdu's boldest new sedan means for UK Denza watchers

Fang Cheng Bao (方程豹, literally 'Formula Panther') is a wholly owned BYD sub-brand created in 2023 to own the adventure and off-road premium segment. Unlike the mainstream BYD Auto range—Seagull, Dolphin, Seal—Fang Cheng Bao sits at higher price points and targets buyers who want a Chinese answer to the Land Rover Defender or Jeep Wrangler. Its first models, the Bao 5 and the Tai series, were PHEV-only. The Formula S is its first pure electric range, a deliberate pivot to attract younger, sport-conscious buyers rather than weekend warriors.

Fang Cheng Bao delivered 29,613 vehicles domestically in July 2026 alone, making it one of BYD's fastest-growing sub-brands. The Tai 7 has already surpassed 200,000 cumulative units. This is not a concept studio project: the brand has the scale, the production infrastructure and BYD's full Blade Battery and DiPilot ADAS stack behind it.

Pre-orders for the Formula S liftback and the Formula S GT estate opened on 20 August 2026, the day before the 2026 Chengdu Auto Show officially opened. Pricing came in below analyst expectations: the range runs from 230,000 yuan to 280,000 yuan (approximately £25,200 to £30,600 at today's exchange rate — for reference only; no UK price exists and tariffs would apply).

The liftback is a large four-door with a 5,060 mm body and a 2,960 mm wheelbase. Three powertrain options cover every buyer: a 245 kW (329 hp) single-motor rear-wheel-drive on a 76.744 kWh LFP Blade Battery, a 300 kW (402 hp) long-range variant on a 92.093 kWh pack, and an AWD twin-motor at 490 kW (657 hp). CLTC range for the standard variant is 720 km; the long-range stretches to 830–900 km CLTC. These are Chinese laboratory figures under CLTC conditions—do not compare directly to WLTP numbers you will see on UK car pages.

Roofline cues visible in official imagery include a LiDAR pod, though the full ADAS specification has not been formally published at pre-order stage.

The Formula S GT is the wagon sibling. At 5,025 mm it is slightly shorter than the liftback, sharing the same 1,967 mm width but with the longer roofline and boot space that defines a proper estate. It uses only the 92.093 kWh LFP battery—there is no entry-level short-range option—and comes in both rear- and all-wheel-drive forms.

CLTC range for the GT RWD is quoted at 800–850 km; the AWD drops to 730 km CLTC. An electrically deployed tow hook is fitted, rated at 500 kg—CarNewsChina described this as 'mediocre' for a car in this segment, which is a fair comment given that European tow expectations for a family estate often start at 1,500 kg.

The GT's styling was described as aligning with the Denza Z sports car that BYD showed at the Goodwood Festival of Speed in 2026. That is not confirmation of a UK launch, but it does give UK observers a tangible visual connection between what was on a UK ramp and what has just opened for pre-order in Chengdu.

The Formula S launches into a Chinese EV market in the middle of an arms race over solid-state batteries (SSBs). Today's parallel Chengdu Auto Show coverage from CarNewsChina confirms that every major Chinese and Western-backed cell maker has converged on 2027 for trial production: BYD (six SSB patents filed in August), CATL (reiterated to investors), Geely (500 Wh/kg target), CALB, Gotion High-Tech (VW-backed, targeting 350 Wh/kg) and Farasis Energy (Mercedes-backed) are all aiming at the same deadline.

The Formula S currently uses LFP Blade Battery chemistry—which BYD has refined into an industry benchmark. An SSB retrofit or follow-on model is speculative at this stage. What matters for UK observers is the trajectory: the brand entering the sedan segment today with 700–900 km CLTC is setting a baseline. If SSB production matures on the 2027–2028 timeline the industry is targeting, a successor Formula S generation could offer genuinely different specifications.

Battery market share data from China EV DataTracker (July 2026) puts CATL at 42.9% and BYD at 19.5%, with CALB, Gotion and EVE rounding out the top five. The top four makers collectively hold over 75% of the market.

No Formula S or Formula S GT is confirmed for sale in the UK. Fang Cheng Bao as a brand has no UK presence. However, the CarNewsChina report notes that the Formula S exterior styling aligns closely with the Denza Z sports car that BYD brought to the Goodwood Festival of Speed in 2026. BYD has a pattern of using its sub-brands—Fang Cheng Bao and Denza—to share platforms and styling between China-market and export configurations. The Denza D9 PHEV MPV is already on UK sale through Electrifying.com listings.

If the Formula S reaches Europe via the Denza channel, UK buyers would be looking at a large-format sports liftback or estate in a price tier above the current BYD Seal. What cannot be confirmed today: UK pricing (tariffs and import costs would significantly alter the Chinese yuan figure), WLTP range (CLTC figures are not transferable), charging speed, or any confirmed RHD production plan.

The one practical takeaway for UK Denza watchers: the Formula S GT estate body style is new territory for the Denza brand — if confirmed for export, it would be the first Denza estate and could compete in a class currently without Chinese representation.
