On August 13, 2026, BYD's Fangchengbao sub-brand added a cheaper entry point to the flash-charging Tai 3 line: a 510 km rear-drive trim at ¥143,800 (~$21,460), ¥10,000 (about $1,490) below the 620 km rear-drive trim that had opened the range since the Flash Charging Edition launched on March 13, 2026. The Tai 3 (Titanium 3) is a compact, boxy electric SUV on an 800V platform with BYD's second-generation Blade Battery, and every Flash Charge trim can take the battery from 10% to 70% in about five minutes and to 97% in about nine at a compatible BYD flash-charging station. The new trim keeps the 240 kW (322 hp) rear motor and is quicker to 100 km/h than the 620 km car (6.9 seconds against 7.3), but it carries a smaller battery, and Chinese trim listings show it without the head-up display and heated steering wheel that the pricier trims include. At the top of the line, the dual-motor AWD trim (¥169,800, ~$25,340) makes 375 kW (503 hp). Outside China the car is badged Denza B3.
Performance & Specs
| Powertrain | Single-motor RWD BEV |
|---|---|
| Power | 240 kW (322 hp) |
| Torque | 305 Nm |
| 0–100 km/h | 6.9 s |
| Battery | ~65 kWh Blade LFP |
| Range | 510 km (CLTC) |
Both rear-drive Flash Charge trims share a single 240 kW (322 hp) rear motor and 305 Nm of torque, and top speed is 210 km/h. What changes is the battery. The new 510 km trim uses a smaller second-generation Blade LFP pack of about 65 kWh, which with a claimed curb weight of 1,920 kg gives 510 km of CLTC range and a 6.9-second 0–100 km/h time. The 620 km trim's 75.6 kWh pack lifts range to 620 km while the sprint slows to 7.3 seconds. The dual-motor AWD trim adds a front motor for a combined 375 kW (503 hp) and 505 Nm, cutting the sprint to 4.7 seconds on the same 75.6 kWh pack with 565 km of CLTC range. Suspension is a front MacPherson and rear five-link layout with BYD's DiSus-C adaptive damping, and the car also has BYD's iTAC intelligent torque control and a one-key drift mode.

Dimensions are the same across the lineup: 4,605 mm long, 1,900 mm wide and 1,720 mm tall on a 2,745 mm wheelbase, a footprint about the size of a Toyota RAV4. Despite the rugged, off-road styling it is a unibody five-seat SUV rather than a ladder-frame truck. Every trim has a 151-litre electrically opening front trunk, and the tailgate carries a further 28-litre external storage box. The new 510 km car has a claimed curb weight of 1,920 kg.

Charging & Battery
All three trims use BYD's second-generation Blade Battery (LFP chemistry) on an 800V high-voltage architecture, and BYD quotes the same flash-charging figures for each: 10% to 70% in about 5 minutes and 10% to 97% in about 9 minutes at a compatible BYD flash-charging station. In extreme cold of −30°C the charge from 20% to 97% takes about 12 minutes. The new 510 km trim has the smallest pack, about 65 kWh, while the 620 km and AWD trims use 75.6 kWh. The battery is built into the body structure (cell-to-body), which BYD uses to stiffen the chassis and lower the centre of gravity.
| BATTERY | ~65 kWh (510 km) / 75.6 kWh (620 km & AWD), Blade LFP |
|---|---|
| ARCHITECTURE | 800V high-voltage |
| RANGE (CLTC) | 510 / 620 / 565 km |
| DC FAST CHARGING | 10-70% in ~5 min / 10-97% in ~9 min (BYD flash-charging station, all trims) |
| COLD-WEATHER CHARGING | 20-97% in ~12 min at −30°C |
Design & Interior
The Tai 3's exterior design language is best described as cyberpunk-meets-off-road: dual-bar LED daytime running lights, an upright grille, flared fenders with scalloped wheel arches and a squared-off greenhouse. The rear carries slim LED tail lights and the "Tai 3 EV" wordmark, and the side-opening tailgate carries an external storage box. Inside, a 15.6-inch central touchscreen sits alongside an 8.8-inch driver display, the front seats are heated and ventilated, and the front windows use double-layer acoustic glass. The 620 km and AWD trims add a 12-inch head-up display and a heated steering wheel; Chinese trim listings show both omitted on the new 510 km trim.
Technology & Features
The infotainment runs on BYD's in-house platform with online navigation and lifetime over-the-air updates. Standard equipment includes BYD's "God's Eye" C advanced driver-assistance system, which supports highway navigation-assisted driving, together with a surround-view camera system, DiSus-C adaptive damping and a tyre-burst stability system that steadies the car from speeds of up to 140 km/h after a blowout. The 12-inch head-up display is limited to the 620 km and AWD trims.
Safety & ADAS
The Tai 3 ships with BYD's "God's Eye" C driver-assistance suite on all three trims. It is a camera-and-radar system that supports highway navigation-assisted driving, and LiDAR is not part of the standard package. A surround-view camera system and a tyre-burst stability system are also fitted, and the cell-to-body battery structure adds rigidity to the chassis.

Pricing & Availability
The 510 km trim went on sale in China on August 13, 2026 at ¥143,800 (~$21,460), ¥10,000 (about $1,490) below the 620 km trim (¥153,800, ~$22,960) that opened the Flash Charging Edition on March 13, 2026, alongside the 565 km AWD trim (¥169,800, ~$25,340). These are official guide prices, and dealer discounts and trade-in subsidies vary by region. The earlier, pre-flash-charging Tai 3 (501 km CLTC), first launched in April 2025 at ¥133,800-193,800 (~$19,970-$28,930), is a separate configuration. BYD sold 5,945 Tai 3 units in July 2026 and 30,372 in the first seven months of the year, according to CnEVPost. Outside China the car is being introduced as the Denza B3: its earlier 501 km CLTC version was shown at the Bangkok International Motor Show in 2026 and presented in Costa Rica in April 2026. As of September 2026, no European or North American launch has been confirmed.
How It Compares
The Tai 3's 510 km trim sits between two established Chinese electric SUVs. The Leapmotor C10 BEV, refreshed in June 2026 at ¥132,800-142,800 (~$19,820-$21,310), is cheaper, claims 660 km of CLTC range and makes 308 hp (230 kW) on an 800V platform, but it is a conventional crossover without the Tai 3's boxy off-road styling. The 2026 XPeng G6 costs ¥176,800-186,800 (~$26,390-$27,880) for 292 hp (218 kW) and 625 km, and its pure-electric trims are rear-drive only, so the Tai 3 AWD at ~$25,340 undercuts it with far more power (503 hp against 292 hp), though with less range (565 km against 625 km).
- Flash Charge line now opens at ~$21,460 (¥143,800), ¥10,000 below the 620 km trim, with the same 322 hp motor
- 800V flash charging: 10-70% in about 5 minutes and 10-97% in about 9 on every trim
- Up to 620 km CLTC range, plus a 503 hp AWD trim that reaches 100 km/h in 4.7 seconds
- 151 L electric front trunk and a 28 L tailgate box in a RAV4-sized footprint
- According to Chinese trim listings, the new 510 km trim omits the head-up display and heated steering wheel
- 510 km CLTC is the shortest range in the line, and real-world highway range will be lower
- Sold in China; the Denza B3 export version has so far only been shown in a few markets, and no European or North American launch is confirmed
The 510 km trim gives the Tai 3 Flash Charge line its most accessible entry point: the same 322 hp motor, a quicker sprint to 100 km/h than the 620 km car and the same five-minute flash-charging capability, for ¥10,000 (about $1,490) less. It gives up 110 km of CLTC range and, according to Chinese trim listings, the head-up display and heated steering wheel. For commuting with home charging it is the value pick; buyers planning longer trips should step up to the 620 km trim, and those who want speed should look at the 503 hp AWD. At about $21,460 it is a distinctive, value-led electric SUV.
