Audi has just released its latest concept design. It is known as the A9  concept and it is unlike anything we have seen in any production car to  date. Audi plans to project its A9 concept at a higher standing than its  current top dog, the A8. Audi predicts that this concept will be  advanced enough to overwhelm first-class luxury models from competitors  such as the Porsche Panamera, and the Lamborghini Estoque if ever it  will be put into production.
The form and features of the 2010 Audi A9 Concept were motivated in  part by the magnificent structural design of Santiago Calatrava’s  architecture in The City of Arts and Sciences located in Valencia. Such  inspiration can be seen in the smooth, sleek and flowing contours of the  vehicle along with its futuristic structure. Calatrava’s constructions  seem as if they were taken from centuries in the future, and Audi’s  concept emulates the same ideals. 
The windshield of this concept car is fully integrated into the roof,  and is composed of material using nanotechnology. Note that this  technology does not exist at this time, since it is designed to  automatically adjust from clear to opaque, change color and repair  damage. Changing colors to the preference of the driver is a feature  also reserved for the body kit of the A9. This means that at the touch  of a button, the car can change from white to black, to red, to blue,  etc.
Propulsion for the A9 concept is achieved via a sophisticated fusion  between electric-powered motors found in each of the four wheels of the  vehicle, working in concurrence with an internal combustion engine using  a renewable source of fuel. Once again, such technology does not exist  as of yet, but the plans for this vehicle certainly sound fascinating.
