I think it's a great thing that Porsche lets us choose between AWD and RWD models. Everyone has their preferences, and both setups have their fair share of benefits. Different strokes for different folks, as they say. You can only respect both camps. The purist mentality for me, is about having the least amount of driver aids possible so that you get the most reward out of your driving experience. You get back what you put in, so to speak. However, it can be tricky to decide sometimes whether or not to go without new technologies if they really do improve your performance/dynamics/driveability. In this case the C2 vs. C4 debate. I normally pefer the C4' heavier steering that retains all of the feel of the C2's. I also like the better balance of the car. But here's an interesting tidbit. The C2's seem to push more whereas the C4 does have some understeer, but will come out neutral if you do your part. You can induce controlled oversteer as well, but naturally it won't be the same as doing it in a C2. Since I like to drive a the limit, the extra security is nice too, especially since it's my daily driver. My trusty M coupe keeps me sharp though, so I don't become too dependent on the technologies, if you know what I mean.
.....and as Tpup brought up the test of the C2 vs. C4 and how the C4 managed it tires better, beating out the C2, I leave you with this quote from an old "Road & Track" article. "Three-time Le Mans 24 Hours winner, five-time Daytona and two-time Sebring champ Hurley Haywood who also won the 1988 SCCA Trans-Am Championship insists that all-wheel drive is superior. It maintains its performance for a longer period of time."
"The Carrera 2 would be faster for one or two laps, mostly because it's about 150 pounds lighter. But over a five-lap period the Carrera 4 would be quicker because it manages its tires better and allows you to lay down power through all four wheels. That's why awd has been banned from just about every racing series."--Haywood
But naturally, RWD simply entertains the driver on a special level, and there's nothing wrong with that
