2008 Porsche 911 Turbo Cabriolet

With 480 horsepower (same as the Coupe), the impact of the Cabrio's 154 extra pounds on acceleration really isn't much noticeable. Measurable? Maybe minutely. But in your hands this is the same, lusty, relativity-probing, mid-three-second-to-sixty 911 Turbo-except the space-time continuum you're warping now includes the open sky. With a press of a button-and a check for $140,000 or so.
