2007 Porsche 911 Carrera 4S Cabriolet Road Test

Forty-four years ago, when the first Porsche 911 went on sale, customers were limited in choice to a solitary model. A single, rear-wheel-drive, 2+2 hardtop body style with a 2.0-litre flat-six cylinder engine hooked up to a five-speed manual transmission. That's it. By 1967, the 911 Targa, with its removable roof panel, was introduced; followed by an S model with more horsepower. As we now know, that was only the beginning. Today, the 911 product matrix is deeper and longer than the Grand Canyon.
