Honorable mention: Porsche 911 Carrera

The 911 Carrera isn't all-new for 2009, though it has been significantly updated: Revised styling, new engines and a new twin-clutch automatic transmission. It's the last item -- which Porsche calls PDK -- that brings it to this list. PDK is what a twin-clutch transmission ought to be. It provides near-instant upshifts and downshifts with absolutely no interruption in power, and I mean none -- PDK can downshift from 7th gear directly to 2nd without even the slightest jolt. It's a truly amazing transmission -- and the 911 has the power and the handling to really put it to good use. I still prefer my Porsches with three pedals, but the 911 PDK is the best automatic-transmission-equipped sports car I've ever driven.
