Government regulatory filings revealed the upcoming luxury passenger car model ahead of its formal retail release, specifying two independent performance configurations sharing a large 3025 mm wheelbase. This sudden regulatory exposure provides a transparent view of the platform hardware driving the brand’s expansion. The new sedan architecture follows closely on the heels of high-profile premium product introductions from the premium joint venture, establishing a clear dual-layout strategy for the brand. This product expansion directly builds upon the fast retail trajectory of the Denza Z9 GT, which surpassed 10000 deliveries within 2.5 months of entering the consumer market. By adding a traditional notchback silhouette to the family, the automaker targets mainstream luxury demographics seeking understated premium proportions. Powertrain and hardware The baseline luxury trim utilises a permanent-magnet synchronous drive motor from Zhengzhou BYD, offering a rated capability of 160 kW and a peak output of 320 kW. This version has a curb weight of 2250 kg and utilises 19-inch wheel configurations with 245/50R19 front and 275/45R19 rear tyres. The underlying energy storage matrix utilises lithium-iron phosphate batteries, with cells manufactured by Hefei BYD and packs assembled by Shanwei FinDreams. The high-performance premium trim significantly increases output metrics by adopting an upgraded Zhengzhou BYD motor, generating a rated capability of 185 kW and a peak output of 370 kW (496 hp). This configuration weighs 2545 kg and employs 20-inch wheels paired with specialised HL275/40R20 tyres to handle the increased power draw parameters. Its lithium-iron phosphate battery hardware relies on cells produced by Wuwei FinDreams, with final assembly completed by Shenzhen BYD. Dimensions and equipment Certified physical parameters establish a broad stance for both sedan variants, with each vehicle measuring 5090 mm in length and 1980 mm in width. The lower-output model is slightly taller, with a body height of 1510 mm, whereas the higher-performance variant sits closer to the asphalt at 1490 mm. Both premium versions are limited to a top speed of 250 km/h and feature standard seating for 5 people. A fixed panoramic glass roof comes standard across the entire regulatory lineup alongside a mandatory automotive event data recorder (EDR) safety setup. Enthusiasts can customise the exterior appearance with optional factory equipment, including a motorised active rear spoiler, unique side-rearview mirror housings, and hidden door handle options. The high-performance variant features additional standalone options, including custom sport wheel rims and a variety of colored brake calliper finishes. Market delivery trends The arrival of the new sedan mirrors the premium automaker’s expanding domestic retail performance curve as it broadens its high-end vehicle portfolio. The premium brand recorded 18,631 sales in June 2026, marking a 19.3% month-over-month increase and a solid 31.1% gain compared with June 2025. These steady volume gains mark a clear departure from early-season registration drops, when winter volumes slipped to 5351 units, according to China EV DataTracker. This new luxury vehicle line slots into a product strategy aimed at solidifying premium market share, following the global path of the Denza Z, which debuted at Goodwood with a pre-sale starting from 184,800 USD. Utilising cost-effective lithium-iron phosphate battery packs across the Z9S lineup enables the automaker to set a highly competitive price bracket. This tactical architecture placement helps secure high-volume retail acquisitions while preserving the top-tier performance prestige of its global 1582 hp flagships.
