There are three things I like in the motoring world: power, efficiency, and shooting brakes (two-door wagons). Delightfully, Audi has just combined all three into one spine-tingling concept car here at the 2014 Detroit Auto Show. All me to I present: the Audi allroad shooting brake. Audi kicks off its write-up of the allroad shooting brake bragging that it hinted at this concept car back at the Frankfurt Motor Show.
