BYD Heyuan Platform Debuts in Denza D9: 30% More EV Range

BYD has unveiled its all-new Heyuan hybrid platform, debuting in the 2026 Denza D9 luxury MPV. The platform's front-mounted exhaust frees space for larger batteries, boosting pure electric range by up to 30% over the current model.

BYD continues to push hybrid technology boundaries with the launch of the new “Heyuan” platform, which first appears in the Denza D9 2026 model. According to a report from CarNewsChina, this platform redefines hybrid powertrain design by integrating the exhaust in the front, freeing up space for larger batteries.

What is the new Heyuan platform?

The Heyuan platform is an innovative hybrid architecture aimed at improving space efficiency and performance. Its standout feature is the integrated front exhaust design, which allows batteries to be placed where traditional exhaust components once sat. This increases battery capacity without affecting cabin or passenger space.

How does the Denza D9 benefit from the new platform?

The Denza D9, BYD’s luxury MPV, becomes the first model to use the Heyuan platform. With larger batteries, the vehicle’s pure electric range is expected to rise significantly—estimates suggest up to a 30% increase compared to the current model. Specific battery capacity and range figures have not yet been revealed.

Additional advantages of the Heyuan platform

Hidden trunk space: The platform frees up 126 liters of hidden trunk space, boosting Denza D9 cargo capacity to 882 liters.
Improved thermal efficiency: The front exhaust design reduces heat transfer to the cabin.
Low center of gravity: Battery placement low in the chassis improves stability and handling.
Scalability: The platform is designed to support multiple future models.
