Here is a quote from the article regarding the test's philosophy for 2009:
Enter 2009's test. For this go-around we addressed a shortcoming that now seems obvious to us. In our efforts to ascertain the best-handling car, we overlooked some vital data: our expert subjectivity. Sure, we'll continue to keenly heed every observation made by Pobst, who graciously joins our team again, but this year we're going to listen to ourselves more, considering such nuances as a car's ability to induce driver confidence and its prowess at enveloping our judges in ergonomic delight.
And here is something about the Cayman S:
What's most striking about the Porsche Cayman S Vehicle Dynamics Score is that it doesn't appear to be remarkable at all. It took turning off our elaborate test equipment and simply wrapping our hands on its steering wheel to finally get the picture ... And when the results were compiled, our affection for the Cayman S became starkly apparent.
Interpret that however you will (there's already an ugly and pointless M3 vs. Cayman S thread, and I don't want to start another one), but the 2009 test is admittedly much more subjective than the 2008 edition.
