Hopefully, this can finally put to rest the fallacy that small 4 cylinder turbos are the way to achieve to best of both worlds - fuel efficiency and power on demand (please don't look at the cars I currently own). A well designed V6 can do everything so much better than a turbo four - hp, smoothness, sound, less complex, longevity, no premium gas required, towing, etc. There may be some exceptions, but in the real world, I'll take a nice 3.5 litre (or 3.0 or 2.5) over a smaller four. I think the same holds true for boosted sixes vs v8s. That being said, however, I suspect I would not think twice about choosing the new mini (3 cylinder turbo) vs the old 1.6 four. I think weight of the vehicle makes a huge difference, but is, of course, only one variable.
