2004 Porsche 911 Turbo Cabriolet Pictures, Specifications, Information

Porsche announced in July of 2003 that it would produce the first 911 Turbo Cabriolet since 1989. The 2004 Porsche 911 Turbo Cabriolet is based on the existing Porsche 911 Turbo Coupe, incorporating the Coupe's engine, body structure, four-wheel drive system, chassis, and suspension and brake systems

Power for the 911 Turbo Cabriolet, transferred through either the manual six-speed or optional five-speed Tiptronic automatic transmission, comes from a twin-turbocharged 3.6-liter six-cylinder engine producing 415 (SAE) horsepower. It propels the car from 0 to 62 mph (100 km/h) in just 4.3 seconds and to a top track speed of 189 mph (305 km/h).

Taking styling features from the 911 Turbo Coupe, the Cabriolet incorporates the Coupe's three large front air intake cooling scoops, intercooler air intakes in the rear side panels, and a rear spoiler that deploys at 75 mph (120 km/h) and retracts at 55 mph (80 km/h). As found on all current Porsche 911 Cabriolets, the Turbo Cabriolet is equipped with a power convertible top that raises or lowers in just 20 seconds. To maintain body stiffness, the 911 Turbo Cabriolet's structure is enhanced with reinforced side-sills featuring body panels and elements doubled in thickness, additional junction plates, and shaft reinforcements behind the B pillar.

Like the Turbo Coupe and all Porsche Carrera® 4 models, the Turbo Cabriolet's four-wheel drive system delivers from five to 40 percent of the engine power to the front wheels depending on driving conditions. The new Turbo Cabriolet is also fitted with the Porsche Stability Management (PSM) system as standard equipment.

To ensure supreme stopping power at all times without the slightest fading, the new Turbo Cabriolet comes with four-piston fixed-caliper brakes plus inner-vented, cross-drilled brake discs front and rear measuring 13.0 in. (330 millimeters) in diameter. Porsche Ceramic Composite Brakes (PCCB) are available as an option, setting new standards in terms of brake response, fade-free performance, low weight and a long service life. Eighteen-inch light alloy wheels with tires measuring 225/40 on the front axle and 295/30 on the rear axle transfer the braking power to the road.
