BYD has shown a modular widescreen interface, called the “Giant Screen UI,” for the third-generation Tang EV, according to Autohome. The five-seat electric SUV is due in China in Q4 2026. It debuted at the Chengdu Auto Show in August and is also known as the 8 Series Tang. In BYD’s domestic lineup it sits alongside the Tang L and the larger Da Tang. Overseas, the Tang L is sold as the Atto 8 or Sealion 8.
Giant Screen UI and the AI companion
Users can combine, resize and tile windows for navigation, media and vehicle information. The system also includes an animated AI companion named “Xiao Mianbao” (“Little Bread”). It uses visual and voice sensing to greet occupants, answer prompts and change its facial expression as it goes.
Two screens, no instrument cluster
A 35.4-inch display at the base of the windshield shows driving data, vehicle status and navigation. It takes the place of both the instrument cluster and the head-up display. A 30-inch panoramic touchscreen covers the centre and passenger side. The layout is fixed and horizontal, a departure from the rotating central screen in some earlier BYD models.
BYD’s interior images show two colour schemes, Dune Beige and Amber Brown, with diamond-quilted leather and a panoramic glass roof. Reports also mention zero-gravity captain’s chairs in the second row.

Battery and flash charging
The Tang EV uses BYD’s second-generation Blade Battery, an LFP pack offered in 88.682 kWh and 105.792 kWh versions. Under normal conditions, BYD says it charges from 10% to 70% in about five minutes and from 10% to 97% in about nine. In extreme cold, around -30°C, BYD quotes 20% to 97% in 12 minutes, roughly three minutes slower than at normal temperatures.
BYD is also building 1,500 kW flash chargers and aims for 20,000 flash-charging stations by the end of 2026. All of these numbers are BYD’s own claims and have not been independently verified.
Motor and range
China’s MIIT filing lists a single TZ205QYD permanent-magnet synchronous motor. It makes 300 kW (402 hp) at peak and 150 kW rated, with a top speed of 250 km/h. CLTC range reaches 850 km on the best version. Any WLTP equivalents are estimates, not official ratings.
Chassis and driver assistance
BYD’s DiSus-A system gives the Tang EV dual-chamber air springs and road-surface preview. God’s Eye B driver assistance is reported as standard. It offers SAE Level 2 highway and urban navigation assistance, so the driver has to stay attentive.
BYD Tang EV (3rd Gen) Launch and pricing
BYD has not announced pre-sale dates or prices. A China launch is expected before the end of 2026.
