Up to this point, Audi has unveiled two Quattro concepts: one at the 2010 Paris Auto Show->ke227 and one the other day at the 2013 Frankfurt Motor Show->ke235. Both were great vehicles, but now Audi needs to decided which of the two will make it to production.

In an interview with AutoExpress, Wolfgang Egger, head of Audi design, said: "With every design concept we do we are thinking about everything becoming reality. We have done one (designed for MQB platform) and now we have done the other (on larger MLB platform) so now we need to make a decision."

But, no matter what concept makes it to production, the new Sport Quattro Concept will influence future Audi models. It reveals how the C-pillar, the blisters and the front will look in the future.

We don't know about you, but we will not complain regardless of which version makes it to production.
