1. Thermal efficiency
2. Mechanical efficiency, from its efficient use of cams, which thereby help keep the weight/friction down and retain the benefits of effectively having a twin cam setup for a v engine with less than two camshafts per bank of cylinders.
Also, the space efficiency of a w design might not have much advantage in a large car, but it does allow VW to use the same engine in other smaller cars if it wishes, eg the w8 Passat , or if brabus etc get hold of it, a w8 Polo probably..
