You've clearly never driven one. The old Cayenne Turbo S was ugly as a hat full of proverbials, but holy crap do they go!
Yes, but it really, really needed that turbo to move at all. The poor man's Cayenne (aka the car people buy who can't really afford a Cayenne) was pretty much changing gears all the time to camouflage the fact that it had no oompf at all under the hood. I was seriously disappointed in that one.
