Audi RS Q3 concept

Audi is set to present its latest concept car, the RS Q3, at Auto China 2012. The concept has been developed around the theme of ‘dynamic performance', with Audi lowering its body by around 25mm as well as widening it with sharp detailing in an attempt to explore the potential of the Q3 model series. The concept's single frame grille is bordered by brushed and polished aluminum trim, while the black grille insert features honeycombs that are slightly offset to each other deeper inside to create a 3D effect.

McLaren 12C Spider: Official
