The timeless beauty of the Porsche 911 range continues with the upcoming release of the new top-of-the-line 911 Turbo S at the Geneva Motor Show (4-14 March). But don’t be deceived by its good looks alone – this new model (the first in five years) has a 30hp increase over the 911 Turbo (up from 500hp to 530hp or 390kW) and maximum torque is rated at 700Nm (516lb-ft). This impressive set of figures are delivered via a six-cylinder “boxer” engine boosted by two turbochargers with variable turbine geometry. The 911 Turbo S reaches 100kmh (62mph) in 3.3 seconds and hits 200kmh (124mph) in 10.8 seconds with a top speed of 315kmh (196mph). Even with its power upgrade, the 911 Turbo S achieves the identical fuel consumption as the regular Porsche 911 Turbo – 24.8mpg (11.4l/100km) which, Porsche says, makes it by far the most efficient in its class.

Exclusively on the 911 Turbo S (optional extras on the Turbo model) are the seven-speed Porsche Doppelkupplungsgetriebe (PDK) double-clutch gearbox – with steering wheel-mounted paddle shift levers – which melds seamlessly with Porsche’s Traction Management (PTM) all-wheel drive. Other performance and safety features include Dynamic Engine Mounts, for high speed rigidity, and Porsche Torque Vectoring (PTV) - including a mechanical limited slip rear differential.

Standard features on the 911 Turbo S include Launch Control function and the Sport Chrono Package Turbo. All that power takes some stopping, hence the vehicle is fitted with lightweight and fade-resistant Porsche Ceramic Composite Brakes (PCCB).

The 911 Turbo S also has as standard Dynamic Cornering Lights, 19-inch RS Spyder design wheels with center lock nut, adaptive sports seats, cruise control, a CD/DVD changer, a Porsche Vehicle Tracking System and vehicle security package to Thatcham Category 5 standard.

Inside, the new Porsche is fitted with exclusive two-tone leather upholstery in Black/Creme or Black/Titanium Blue.

Porsche says further technical and specification details will be confirmed nearer the on-sale date.

The new Porsche 911 Turbo S goes on sale from May 2010 priced from £123,263 (US$193,343 approx) in Coupe bodystyle and from £130,791 (US$204,090 approx) as a Cabriolet.
