My guess,is that VW was going for remarkable efficiency,and this guided all parameters of the design.
The 2011 version was Cd 0.186,16.1 sq-ft frontal area,for a drag index of CdA 2.994 sq-ft,and 261-mpg hwy.
With garden-variety mirrors,it's Cd could grow to 0.201.
The larger XT Sport,with 'real' tires degrades to Cd 0.26,and that's without mirrors as well.
