Big SUVs love to shout. This one doesn’t need to—its numbers do the talking.
BYD has published the first official images of its new D-segment flagship SUV, the Great Tang (known as “Datang” in China), and locked in a March 5 reveal. The pictures were shared by Lu Tian, General Manager of BYD’s Dynasty Network Sales Division, via social media—an unusually direct, very modern kind of “official” for a launch that’s clearly meant to make waves beyond China’s borders.
Even before these images dropped, filings in China’s MIIT declaration catalogue had already sketched the Great Tang’s footprint. It’s a long, wide, three-row machine—measuring between 5,263 mm and 5,302 mm in length, 1,999 mm in width, and 1,790–1,800 mm in height. The wheelbase is 3,130 mm, a figure that usually signals one thing: real cabin stretch, not just clever packaging.
And yes, it’s a seven-seater. Properly so, at least on paper, with the kind of wheelbase that should keep the third row from feeling like an afterthought.
The spec sheet hints at two top-speed figures—240 km/h or 250 km/h—while weight varies significantly depending on configuration. Curb weight ranges from 2,640 kg to 2,970 kg, with gross vehicle weight listed between 3,245 kg and 3,575 kg. Those are heavy numbers, the kind you expect from a flagship SUV built around a large battery pack, a large body, and the equipment list buyers now treat as non-negotiable.
Wheel and tyre options are equally upscale: 21-inch rubber at 265/45R21, plus 20-inch options in 255/50R20 or 275/45R20. Track widths are listed at 1,715 mm up front and 1,725 mm at the rear, suggesting a planted stance rather than a tall, narrow “people mover” profile.
BYD is also baking in luxury cues as standard. A panoramic sunroof comes as part of the baseline spec, and the overall height depends on suspension choice: 1,790 mm with air suspension, 1,800 mm without it. Choose the rear bumper decorative elements and the SUV stretches to the longer 5,302 mm figure—paired with front and rear overhangs of 995 mm and 1,177 mm, respectively.
Battery chemistry is listed as Lithium Iron Phosphate (LFP), which is classic BYD: durability, thermal stability, and long-cycle life over chasing the most aggressive headline energy density. For a large family-focused SUV, that trade-off often makes sense—especially in markets where reliability and long-term ownership costs matter as much as acceleration bragging rights.
But the part that will get EV-watchers leaning in is what’s expected for the pure electric version. The Great Tang is set to use BYD’s Super e-platform with a full-domain 1000V high-voltage architecture. That’s the kind of electrical backbone you build when fast charging isn’t a feature—it’s the story.
BYD pairs that 1000V system with a 10C “flash charging” battery and a 1000A charging current, projecting charging power of up to 1000 kW. Read that again: one megawatt. If the real-world charging curve holds up anywhere near that claim, the Great Tang won’t just be competing with other large electric SUVs—it’ll be challenging what drivers think “waiting to charge” even means.
That promise also connects to BYD’s broader rollout: the company has already signaled large-scale deployment of Megawatt Flash Charging Piles, and the Great Tang is positioned as one of the models ready to tap into that next-gen infrastructure. In other words, this SUV isn’t arriving alone. It’s arriving with a charging ecosystem behind it—exactly how you shift an EV from impressive on paper to easy in everyday life.
March 5 will fill in the gaps: final trims, power outputs, range figures, pricing strategy, and—crucially—how much of that megawatt-charging ambition is available at launch versus “coming soon.” Either way, BYD’s message with the Great Tang is already clear. The flagship era isn’t only about bigger cabins and nicer materials anymore. It’s about electricity delivered faster, smarter, and at a scale that matches the size of the vehicle.

Big cabin, proper 7 seats, thats rare. But heavy, and megawatt network sounds like a must-have not a nice-to-have. price will tell if it lands, still curious

1MW charging? wow. sounds amazing but where are the chargers actually gonna be, and how fast after heat soak? LFP + 2.9t = questions…
