1) You cannot make a 4-pot sound like a 6-cyl, FAIL
2) Porsche engines are not V6s, they are flat-six engines and have been since the war, FAIL
3) The VR6 - with, as Oli points out, a 15* v-angle - is more like an inline six than a true V6 with a 90* v-angle. This allows for a very compact 6-cylinder where a traditional inline 6 or V6 would not fit. The firing order is also more akin to an inline six than a V6. As such it is incorrect to consider the VR6 as a true "V" - more as a subset of "inline" 6. Volkswagen AG does have traditional V6 engines amongst its lineup though; the 3.6 V6 is a proper V engine as I recall. So, somewhat less, but still FAIL
4) I think we've covered everything.
