A car often undergoes subtle unadvertised changes throughout its sale period. Manufacturers may alter fastening shapes, improve potentially damaged components, or seek ways to reduce costs.

For the 2024 Toyota GR Corolla, there are few changes, including new bolts, a pair of air ducts, and four pieces of aluminum tape for improved aerodynamics.

We are particularly interested in the latter, the aluminum tape. How can such a simple, light, and inexpensive item have an impact on aerodynamics?

In a video released by Ken Gushi, showcasing the installation of 2024 components on his 2023 GR Corolla, the adhesive tape is seen as a curious upgrade for him as well.

The tape comes in the 2024 upgrade package alongside new rear subframe bolts, new steering bolts, air ducts, and the aforementioned tape. One might expect the tape to help seal air gaps or reinforce flexible parts, but instead, it controls electrostatic discharge.

This concept has since been patented by Toyota. The car generates positive charges while driving, and the surrounding air is also charged. When two positively charged objects touch, the air around them is disturbed.

According to Car Watch, this idea has been around since the mid-2010s and was initially tested on the Toyota 86. During the development of the 86 facelift model, Toyota engineers identified inconsistent behaviors among test car units, especially when the front bumper material was changed from prototype specifications to production specifications.

This led to the study of electrostatic discharge and the discovery that aluminum tape solved this issue and seemingly improved aerodynamics like magic
