Going against most coupe-and-convertible pricing strategies, wherein the roofless versions are priced higher than the hardtops, the Cayman hit the streets for 2006 with an elevated base sticker compared with that of its Boxster sibling. Porsche’s current argument for that arrangement is that the Cayman is a better performer, as it weighs less and has more structural stiffness provided by its hardtop and the engines it shares with the Boxster are tuned for more power. For 2009, the Cayman receives its first freshening, with the base model offering an enlarged flat-six, an optional seven-speed dual-clutch automated manual transmission (PDK in Porsche-speak), and other various tweaks. But one thing remains unchanged: The Cayman is still at the top of its game.
