David Cardoso has conceptualized a futuristic amphibious car that has been named the Audi Hydron. The Audi Hydron will be able to drive on land and if needed it will be able to drive on water as well. Each wheel is powered by its own electric engine that can turn 90 degrees.. However, in the water, the Audi Hydron will be driven by hollow axe wheels.
The concept also features a number of different driving modes such as parking mode and rotation mode. Depending on what the driver prefers and the driving conditions, the Audi Hydron supports front, rear or four-wheel drive.
