In spite of the convertible-specific reinforcement of the chassis and automatic and the extendable rollover protection behind the rear seats, the open version of the 911 Turbo only weighs 70 kilos more than the Coup. The light, three-layer soft top, which can completely automatically be opened or closed in roughly 20 seconds, enables a low balance point.

Together with the running gear that is tuned to convertible-specific needs, which includes the active suspension system Porsche Active Suspension Management (PASM) as standard equipment, the new 911 Turbo Cabriolet offers the sporting driving performance typical for a Porsche 911 as well as extremely high driving safety together with appealing driving characteristics. The driving stability control Porsche Stability Management (PSM) and the managed all-wheel drive Porsche Traction Management (PTM) also contribute to its uncommon performance. The system with an electronically controlled multi-plate clutch can, according to the requirements, alternatively shift the drive output from the engine between the front and rear axles, and with shift intervals of a maximum of 100 milliseconds quicker than the reaction of the engine to load changes.

With a drag coefficient of Cw=0.31, the 911 Turbo Cabriolet travels at the level of the coup models. Together with the rear spoiler, which automatically extends at speeds from 120 km/h extending 30 mm further than with the Coup, the vehicle is the only standard series convertible that generates negative lift at the rear axle. Along with its passive safety systems, including six airbags as standard equipment and the comprehensive rollover protection system with steel tubing integrated into the windshield frame and an extendable rollover protection behind the rear seats the 911 Turbo Cabriolet also fulfils all legal requirements for passive safety applicable in the worldwide sales markets. Furthermore, it is equipped with one the most high-performance brake systems. The six-cylinder fixed-brake caliper up front stems from the Porsche Carrera GT. Upon request, the race-proven and light Porsche Ceramic Composite Brake (PCCB) ceramic brake system is also available for the 911 Turbo Cabriolet.

Also included in the extensive standard series equipment of the 911 Turbo Cabriolet are Bi-Xenon headlights, 19 inch forged wheels with two-tone appearance, an air conditioner, the wind deflector, the Porsche Communication Management (PCM) with the navigation module and 5.8 inch color monitor and the Bose Surround Sound System, among other things.
