BYD Patented Facelifted Denza D9 Long-Wheelbase MPV

BYD has filed a patent for a facelifted version of the Denza D9 luxury MPV with a longer wheelbase in its home market. China's National Intellectual Property Administration published images showing the vehicle, which is credited in part to chief designer Wolfgang Egger.

Design Changes

The patented model features an all-new front face with a larger grille and vertical lines. The powered doors are slightly longer, the pillars are redesigned, and the LED tail lights look sleeker while flowing further into the rear quarter panels. Exact dimensions are not revealed, but visual comparisons show a stretched wheelbase.

Features And Tech

Patent images match earlier test mules, showing fender-side cameras, a roof-mounted LiDAR unit, and identical alloy wheels. Equipment will likely match the standard D9 updated in April, which features up to ten screens, an AI cockpit, and heated, ventilated, and power-adjustable seats. Second-row options include sixteen-point massage seats. The vehicle uses BYD's DiSus-C active suspension to reduce motion sickness and handle high-speed tyre blowouts, while the DiPilot 300 system handles assisted driving.

Powertrain Options

Global markets get the D9 in PHEV and pure EV formats. The BEV variant uses a 115 kWh LFP battery pack offering an 800 km CLTC range and a 648 km WLTP range, driven by a 340 kW front motor. The PHEV offers 58.5 kWh and 66.5 kWh battery options with pure EV ranges of 350 km and 401 km. Both versions support Flash Charging.

Context

Patent filings often give the public a first look at upcoming vehicle updates before official market releases happen. BYD is preparing to launch its Denza brand in India with the standard D9 MPV, making future variants like this long-wheelbase version potential candidates for later introduction.
