The evocative twin-turbocharged, 3.6-litre flat six engine has been tuned in the Turbo S model to develop more power and torque for even greater performance – and Porsche engineers have achieved this while ensuring fuel consumption and emissions barely differ from the standard Turbo model.

The vital statistics of the Turbo S are impressive. Power is raised to 444 bhp, and pulling power leaps to 457 lb-ft. This increase in engine responsiveness manifests itself particularly during in-gear acceleration – which is stunning. The engine delivers these remarkable figures courtesy of larger turbochargers, modified intercoolers and revised engine management electronics. Additionally, the six speed manual transmission has been strengthened to handle the torque increase.

The brakes of the 911 Turbo S have also been uprated similarly. Fitted as standard are the Porsche Ceramic Composite Brakes (PCCB) system, offering a 50% weight reduction per wheel over the conventional steel brake disc equivalent, as well as superior fade resistance characteristics under heavy braking.

Standard equipment on the Turbo S includes metallic paint (including a special colour – Dark Olive metallic), Xenon headlights, a BOSE audio system and the Porsche Communication Management System (PCM) incorporating audio, telephone and satellite navigation functionality. Additionally, the Turbo S offers 18" alloy wheels painted in GT Silver metallic, plus full leather interior trim, aluminium-coloured instrument dials, cruise control and a CD autochanger.

The Porsche 911 Turbo S Coupe is priced at $131,400.

Porsche 911 Turbo S Cabriolet

Taking the performance potential of the Turbo S Coupe and adding the versatility of an electric folding roof, the Turbo S Cabriolet is the ultimate expression of open-top 911 motoring. Roof operation is electro-hydraulic and allows the driver to open or close the roof fully automatically in just 20 seconds at the touch of a button. And to allow even greater flexibility, the driver can choose to lower or close the roof either at a standstill, or at speeds of up to 31mph (50km/h). Like all Porsche 911 Cabriolet models, the Turbo S also comes as standard with a removable aluminium hardtop - weighing only 33kg - for year-round convenience.

The Turbo S Cabriolet shares the same 444 bhp engine as the Coupe, and has a six-speed manual gearbox. However, both the Coupe and Convertible Turbo S models can be ordered with the Porsche Tiptronic S five-speed automatic transmission.

When looking at the dashboard, the driver’s eye immediately notices not only the aluminium-coloured dial faces but also the “Turbo S” logo on the rev counter. If buyers decide in favour of natural leather, this material is specially embossed on the middle strips of the seats, the steering wheel rim (where it is handled), the shift lever and the hand brake lever.
