The Tang EV brings a fully electric drivetrain to BYD's flagship three-row SUV, and its near-silent cabin makes every other detail, including how smoothly a running board operates, more noticeable. Decoin built its electric running board for the Tang EV around that expectation of quiet, reliable operation at every door.
Every time a door on the Tang EV opens, the running board extends automatically to offer a stable step for passengers heading to any row, then retracts flush against the body once the door closes.
Because the Tang EV has no engine noise to mask mechanical sounds, the running board's motor is tuned for smooth, low-noise deployment that fits the EV's refined character.
The board's retracted position is designed to sit close to the body, so it adds negligible aerodynamic drag and has no meaningful effect on the Tang EV's driving range.
Whether at home or at a public charger, the step makes getting in and out easier at every stop, without interfering with the charging port or access panel.
Will this reduce my Tang EV's range? The retracted, flush position has negligible aerodynamic impact, so any effect on range is minimal.
Does the running board work with all three rows of doors? Yes, it's designed to deploy in sync with every door on the Tang EV.
Is it quiet enough not to be noticeable in a silent EV cabin? Yes, the motor is designed for smooth, low-noise operation.
