BYD Song Plus DM-i Trunk Storage Box Overview

Turn the spare space under your trunk floor into a tidy, OEM-style organizer. This upgraded underfloor storage box is molded for the BYD Song Plus DM-i (SEAL U DM-i in many markets) and is also offered for Song Pro and Song EV. The latest revision adds lock holes so you can fasten the tray with the vehicle’s own screws, and uses one-piece supports for a firmer, quieter fit.

Key Features

Lock-hole mounting: use the original trunk screws through the molded holes to keep the tray from shifting or buzzing.
Integrated feet: one-piece supports — place the box in the well; no separate stand to assemble.
Smarter compartments: deepened and re-zoned storage for everyday tools and emergency gear, with removable side panels when you need a wider bay.
Molded handles: redesigned lifts that do not steal usable volume.
Reinforced base: dense underside ribs for load-bearing strength in daily use.
PP construction: durable black polypropylene, easy to wipe clean; optional flocked finish variants exist for quieter cargo.
