Created by Russian designer Alexander Tiganova, the Audi A0 QS concept is an eco-
friendlysports car, equipped with a hybrid drivetrain, consisting of an electric motor and a
hydrogen engine. 
  
Besides the dynamic look and the sport oriented style, this concept vehicle benefits
from a
special rotation system of the wheels, inspired by the trike, that allows the wheels to
turn just by bending, without rotating along the vertical axis. The “Q” in the concept car’s
name stands for four-wheel drive and the “S” for support, according to the designer. This Audi
concept car’s doors are made from a rubber fabric, that can turn transparent, depending on the
 driver’s needs. With a length of just 3.4 meters, this futuristic vehicle would have a great
advantage when driving on busy urban roads, or when parking.
