The Song Plus DM-i's hybrid drivetrain is built around efficiency, and Decoin's electric running board follows the same philosophy — it only extends when it's actually needed, tucking away the rest of the time so it never adds drag or bulk to the SUV's profile.
The running board deploys the instant a door on the Song Plus DM-i opens, offering a sturdy step for passengers, then retracts flush against the underbody once the door is closed.
Because the DM-i variant is built around fuel efficiency, the running board's retracted position is designed to sit close to the body, minimizing any impact on aerodynamics while driving.
Whether you're plugging in at home or filling up on a longer trip, the step makes every stop a little easier, especially when loading passengers or cargo.
Sealed against moisture and road grime, the mechanism is designed for years of reliable use without extra maintenance.
Does the running board affect the DM-i's fuel economy? Its retracted, flush-mounted position is designed to have negligible aerodynamic impact.
Is it compatible with the DM-i's specific body kit? Yes, the kit is fitted specifically to the Song Plus DM-i's factory mounting points.
Does it interfere with charging access? No, the board is positioned clear of the charging port and access panels.
