BYD delays Great Tang as preorders outrun Blade Battery 2.0 supply

Chinese automaker BYD has postponed the launch of its refreshed Great Tang SUV to June 8, 2026, after earlier expectations pointed to a late-May debut, according to CarNewsChina. The same outlet reports preorders above 100,000 units and says Blade Battery 2.0 pack output could not keep pace with that demand. Electrek independently confirms the delay, the preorder figure, and the second-generation Blade supply constraint. The slip is short on the calendar. The signal it sends about cell capacity is louder than the revised date.

What the report says

Per CarNewsChina, the postponement is a battery supply issue rather than a vehicle issue. Pre-sales opened, demand ran ahead of forecast, and the Blade Battery 2.0 packs needed for early deliveries are the bottleneck. Electrek reaches the same conclusion from its own reporting. BYD chairman Wang Chuanfu has also acknowledged a severe shortage of second-generation Blade capacity as flash-charge EV demand overwhelms production, which adds corporate weight to the supply-constraint framing.

The number worth marking is 100,000. Both outlets treat it as the proximate cause of the slip, and it is a large order book for a single nameplate refresh. Customers who placed deposits should expect staggered deliveries rather than a single ship date.

Blade Battery 2.0 is a distinct, newer pack than the original Blade Battery. BYD's official announcement cites roughly 5% higher energy density than the first generation and 10-70% state of charge in about five minutes via flash charging. The Great Tang delay therefore points at a specific, high-demand cell line rather than generic LFP supply pressure.

AutonomyEV's opinion

A delivery slip on a high-demand SKU is a predictable result of opening preorders on a vehicle whose cell line has not finished ramping. The interesting question is whether BYD keeps doing it. If later launches open order books before newer Blade output catches up, the company is effectively using customer deposits as a forecasting tool. That works once. It erodes trust when the pattern repeats.

There is a competitive read too. Any rival LFP cell maker that can deliver comparable energy density at volume in the second half of 2026 gets a real opening while BYD appears to be rationing its newest packs across its own nameplates. We have not seen public confirmation of which other BYD models share the same cell line, so treat the internal-queue argument as analysis rather than confirmed fact. The Tang delay by itself is small. The capacity story behind it is the one to track.
