2.0 or 2.5?

2.5L PDK all the way. Having had PDK on my last car I don't think I'd never go back to manual now, even a manual as good as those available on a Porsche. The only 2.0L PDK I drove had far too much lag for my tastes. Maybe another example might be better, but I can only form an opinion based on the one that I have driven & it wasn't for me. In any case I don't mind paying extra for the increased torque (from lower RPM), the additional power & the reinforced front brakes (not sure if the latter makes any discernible difference). The fact the S is fitted with larger standard wheels also means that the upgrade to the 20's I have fitted was cheaper & that's several hundred pounds of the price difference between the cars back ($1190 in the U.S). I'd be interested to know just how much more economical the 2.0 litre is in real world driving given as it runs with a higher boost pressure. I'm finding the 2.5L to be pretty good & obtaining low to mid 30's on a long run, providing I behave of course. That's not far off the claimed figures & far better than I was actually expecting. All the more so as the engine is still going to be pretty tight. I'm even returning 28mpg or so locally & given the type of roads we have that's come as a pleasant surprise as well. I would assume the figures will improve even more as a greater mileage gets covered & the engine loosens. I've already stated previously that I didn't particularly like the sound of either engine without a Sports exhaust & that still stands, but the 2.5 is certainly pretty decent with it (I can't comment on a 2.0L fitted with a sports exhaust as I've never driven one).
