> Volkswagen just build the world's most aerodynamic road car ever.
A drag coefficient of 0.158 is not quite setting a record. Aptera's road-legal car has a coefficient of only 0.13, while Hyundai achieved a drag coefficient of 0.144 with the Aero Challenge concept car [1] (but it's not clear whether that vehicle is road-legal, or even what it looks like).
