We designed our High-Efficiency Trunk Spoiler to help improve the aero efficiency of Tesla Model 3. Using the latest in aero simulation and CAD technology, we engineered a spoiler that looks great, is simple to install (no drilling), doesn't impede the rearward visibility of a driver, and most-importantly, reduces overall drag!
During the R&D process, we found that we were able to reduce total vehicle drag by 6.3%, representing an improvement of 273% over the OEM spoiler available on the Performance trim level. In addition to the efficiency improvements, we were also able to increase rear downforce (helping to improve stability at speed) by 83.7% over having no spoiler at all. Patent pending.
