Porsche is introducing its open-top 911 Carrera 4S in October. The manufacturer claims the 2004 car accelerates to 100 km/h in just 5,3 seconds, two tenths of a second slower than the Coupé despite an extra 70 kg.

The 2004 Carrera 4S Cabriolet features a 235-kW 3,6-litre six-cylinder engine, which Porsche says, with the roof closed, can reach a maximum track speed of 280 km/h, matching that of the current 911 Carrera 4S Coupé.

The soft top features a zigzag folding. It takes about 20 seconds for the roof to unlock and fold back neatly beneath a protective cover. At speeds of up to 50 km/h, the driver can operate the convertible top simply by pushing a button.

The car's rear wing is 60 mm wider than that of the 911 Carrera. It borrows the characteristic light strip between the rear lights from the Coupe.

The attractive lines are emphasised by its rear wing, which is 60 millimetres wider than that of the 911 Carrera.

It features the Turbo’s brake system, with perforated and internally ventilated brake discs with a diameter of 13 inches. Eighteen-inch light alloy wheels with tyres measuring 225/40 on the front axle and 295/30 on the rear axle transfer the braking power to the road. It can be fitted with Porsche's PCCB ceramic brake system.

The Carrera 4S Cabriolet comes with an extensive range of standard equipment. This includes leather interior, a hardtop and wind deflector.
