Patent Filing and Design Details
BYD has officially filed a patent for a long-wheelbase variant of the Denza D9 MPV. Published images from China’s National Intellectual Property Administration reveal a stretched design closely resembling the regular D9 model, with chief designer Wolfgang Egger listed among the creators.
The appearance of this filing confirms that development is actively progressing, following the first prototype sightings that emerged in early 2026.
Sales Performance and Context
The standard version of the vehicle received a refresh in April 2026, offering up to 10 display options such as armrest screens, headrest displays, and a ceiling-mounted screen. Meanwhile, domestic market performance remains active, with China EV DataTracker reporting 5,056 domestic deliveries for the D9 in September 2026.
