Chevy Bolt EV Wheel Fill Plate

The Chevy Bolt EV has been my favorite car to own and drive. But, it has one of the worse drag coefficients when compared to other EVs (which reduces range). For this reason, I wanted to try my hand at improving my favorite car.

While in theory, this should work. I do not have any hard data showing that these fill plates help or hinder.

These plates are not perfect. While they do snap into the wheel, modifications can be made to make them better (i.e. making them more flush with the top of the wheel, adjusting the open for the valve stem). I hope others will try these and come up with improvements to help Bolt EV owners everywhere enjoy their cars a little more.

Update: I originally printed the wheel inserts (shown in the photos) using PLA. I live in Texas and we are starting to see temperatures of 90-100 *F. Due to the temperature, some of the inserts warped and fell off. I would highly recommend printing the inserts using a high-temperature resistant material. I'm going to attempt using PETG and will add an update when/if possible.

Update: I have made the Fusion 360 (.f3d) files available to make them easier to remix. I have not had a chance to try printing in a different material. Hopefully, I can find some time between moving and home improvements to do so.
