Is the shape of a raindrop the most aerodynamic shape? Wouldn't the fluid change shape as the air acts on it to be perfectly aerodynamic? - Quora
Speed Physics - Streamline Mode, reduces downforce to reduce drag by creating a 'long tail' effect using the fan's thrust. Less drag means less fuel consumption increasing efficiency | Facebook
