BYD Seal 08 exposed in regulatory filing: 1,000 km range, Blade 2.0, Q2 launch

BYD’s Ocean network flagship sedan, the Seal 08, has appeared in the Ministry of Industry and Information Technology’s (MIIT) 405th batch of new vehicle announcements. The model is scheduled for market launch in the second quarter of 2026, positioned as a mid‑to‑large fastback sedan with advanced electrification and chassis technologies, according to Autohome.

Technical overview

The Seal 08 measures 5,150 × 1,999 × 1,505 mm with a 3,030 mm wheelbase. It is built on BYD’s 800V high‑voltage platform and integrates the DM‑i hybrid system. Powertrain components include a 1.5L BYD472ZQB engine rated at 115 kW and a permanent‑magnet synchronous motor rated at 200 kW. The vehicle employs BYD’s second‑generation Blade Battery, which uses lithium-iron phosphate chemistry.

The battery supports flash charging at megawatt levels, with BYD claiming it can replenish 400 km of range in 5 minutes. with a CLTC‑rated pure electric range target of over 1,000 km. The model also incorporates rear‑wheel steering and BYD’s “DiSus‑A” (Cloud Chassis A) active suspension system.

Product and design

The Seal 08 continues the Ocean‑S concept design language, with a closed front fascia, slim headlamps, and a raised hood profile. The roof houses a lidar sensor, confirming integration of BYD’s latest “Eye of God B” driver assistance suite. Side elements include a coupé‑style roofline, semi‑hidden door handles, and large multi‑spoke wheels. The rear adopts a full‑width light bar.

Standard equipment includes a panoramic glass roof. Options cover wheel designs, rear badging, door handles, and interior mirror bases. Interior specifications have not yet been disclosed, but flagship positioning suggests large display integration and advanced safety systems.

Market positioning

Pricing is expected in the 300,000–350,000 yuan range (≈42,000–49,000 USD). This places the Seal 08 against the Tesla Model S, Nio ET7, and Xpeng P7 in the premium electric sedan segment. Within BYD’s Ocean lineup, the Seal 08 sits above the Seal 07 and Song L, extending the brand’s fastback sedan portfolio.

Industry context

BYD unveiled the Seal 08 on March 6, framing it as the Ocean network’s flagship with a 1,000 km range target and Blade Battery 2.0 (CNC launch coverage). The battery’s dual‑format design—short blades for 8C flash charging, long blades for 210 Wh/kg density—was detailed on March 10 (CNC breakdown), underscoring BYD’s attempt to balance infrastructure speed with energy storage.

The filing also comes as BYD weighs overseas expansion, including Canadian production and possible acquisitions of legacy automakers, while domestic competition intensifies with Xiaomi’s SU7 entering the premium EV sedan space on a 897V platform. Against this backdrop, the Seal 08’s megawatt flash charging and Blade 2.0 chemistry mark a strategic response to both regulatory trends and rival launches.

Outlook

The Seal 08’s MIIT filing confirms BYD’s technical trajectory: second‑generation Blade Battery, megawatt flash charging, rear‑wheel steering, and active suspension. With a Q2 launch, the model is set to become a focal point in China’s premium EV sedan market, combining regulatory compliance with flagship positioning.
