Remember, on a V engine, the cylinders are staggered when looked at from above. This is done so that the connecting rods on the crank can sit next to each other. So you always have one side offset from the other. In a V5, you simply omit one cylinder from one side, so it kind of looks like a W from above. When you put the engine transversely, it ends up being shorter than a V6 or I4. And in VW's case, they use a shallow V so that there is still only one head.
Remember, VW/Audi has a lot of experience with 5 cyl engines in the 80/90/100/200 series cars (that the US got as the 4000 and 5000).
