When your desktop needs a little color, it means it needs this astonishingly attractive Audi wallpaper! This is none other than 2012 Audi R8 e-Tron, a four wheel drive electric car most of us would love to try. Shorter, lower and narrower than the standard R8, Audi R8 e-Tron will have a total output of 313 horespower hitting 100km/h in less than 5 seconds and reaching a top speed of 200km. Quite good for an electric car! And great for a wallpaper!
