A scientific explanation in the age of science denial.You'd think so, but you would be wrong. Read the part down the page about the aerodynamics.
We have carefully designed and adjusted the P17A1 to optimize airflow and reduce air resistance, resulting in a 70% air resistance reduction compared to the traditional teardrop trailers. Inspired by F1 vehicles, P17A has a full flat Aero underbody with vertical fins that helps to reduce air drag. Vortex generator on top of the P17A helps reduce drag by directing the air completely behind the trailer.
