The Cabriolet was built to offer the thrills and the look of a 911 Turbo version, but with a top that could be dropped for a pleasant, relaxed drive.
For the 2010 model, the car featured large air intakes and bar-shaped LED turn-signals. In the side-scoops air intakes needed to cool the front brakes, the designer incorporated the daytime running lights with LED, instead of the usual foglights. The headlights featured optional dynamic lights that improved illumination on the bends due to a swiveling mechanism. On the upper side of the rear fenders, a twin air-intake was placed to help to cool and feed the engine with fresh air. The wing on the engine hood made an important aesthetic difference between the Turbo and the rest of the 911 models.

The interior was fitted as standard with a three-spoke steering wheel and aluminum paddle-shifters behind, to manually control the gears. The sport-bucket seats were fitted as standard. For the infotainment unit, Porsche installed the PCM (Porsche Communication Management), with iOS compatibility. For Android users, the car-manufacturer offered a special application. The power-roof could open or close the top in 20 seconds at speeds up to 50 kph (31 mph).

The first Porsche 911 Turbo Cabriolet appeared in 1975 and offered a 260 hp from a flat-six 3.0-liter engine. The 2010 Turbo S Cabriolet featured a new engine management system that allowed a more aggressive of the intake valves and a bigger boost for the turbochargers from 1 bar (14.5 psi) to 1.2 bars (17.4 psi). The result was an increase in power by 30 hp over the regular 2010 Porsche Turbo. The direct-injected 3.8-liter engine was mated as standard to a 7-speed PDK (double-clutch) automatic gearbox.
