I loved the VR6 I had in the Jetta, back when it was only a 2.8 liter.Passat VR6
It was fairly thirsty, even in the smaller displacement. But it was amazingly smooth.
I'm surprised they didn't go back to the 2.8 and add a supercharger to it. It'd be difficult to turbocharge it, as the head is "flow-thru" with the intake and exhaust on different sides.
