How Much Horsepower Do You Need (Given Today's High-Tech Cars)?

Follow this link to a very good piece published on Wired just a few days ago.  It's about the upper limits of horsepower, or what is practically feasible.  Maybe it isn't just all about horsepower, and Porsche seems to be in the lead towards this kind of rethinking.  New lighter materials, design features, and technology all contribute to a car's feel and the experience one has with it.  No manual transmission is available on the 2015 GT3, unfortunately, but it's still a beauty.
