Porsche's least-expensive convertible is offered with only minor changes for 2005, in base and S trim levels. A 225-horsepower, 2.7-liter six-cylinder engine, coupled to a five-speed manual transmission, comes standard, while the S receives a 258-horsepower, 3.2-liter six-cylinder powerplant and a six-speed manual gearbox. Both models can be equipped with a five-speed automatic transmission that offers manual gear selection. A power-operated top, along with four-wheel anti-lock disc brakes, automatic air conditioning with air filtration, a CD stereo, speed-dependent extendable rear spoiler, partial-leather upholstery, heated washer nozzles, and locking alloy wheels come standard. For customization's sake, an Aerokit Package with integrated front and rear spoilers is offered, along with one of the longest lists of available interior and exterior cosmetic tweaks in the business. A second-generation model arrives early next year as a 2006 model.
