New Porsche Cayenne Turbo S with 550bhp 4.8-litre twin-turbocharged V8 has been unveiled. The new Cayenne Turbo S gets extra 50 hp and 50 Nm (now at 750 Nm) torque over the standard Turbo model.

0-62mph comes in just 4.5 seconds (0.2sec quicker than the standard Turbo) and the top speed is 175mph (+2mph).

Despite extra horsepower and torque, the fuel consumption has not changed and is still 24.6 mpg.

The new Cayenne Turbo S features familiar air suspension and active PASM damping control found on the standard Turbo, but adds also a Dynamic Chassis Control, which uses hydraulic roll bars to reduce body roll in corners, Torque Vectoring Plus, which combines torque vectoring on the rear wheels with an electronically controlled rear differential lock to improve traction.

Visually the Cayenne Turbo S is distinguished from the rest fo the Cayenne range with new 21-inch 911 style alloys, gloss black trim, new exhaust tips and a two-tone leather upholstery along with a carbon fibre trim.

The new Cayenne Turbo S is priced from £107,460 and will arrive in Porsche Centres in January 2013.

From the press release:

Flagship Porsche Cayenne model with 550 hp 4.8-litre twin-turbocharged V8
Power increase of 50 hp and 50 Nm torque over Turbo model
0-62mph in 4.5 seconds
On sale January 2013, priced from £107,460
With the power output of its twin-turbocharged engine increased by ten per cent to 550 hp, the new Turbo S is the definitive Porsche Cayenne in which to cover ground quickly. With its advanced active chassis dynamics, the supreme four-wheel drive, five-seater surpasses the driving performance of many sports cars.

The intrinsic Cayenne virtues of versatile off-road capabilities, ride comfort and superior towing power have been preserved without exception. Its NEDC fuel consumption of 24.6 mpg is identical to that of the Cayenne Turbo, which makes it more fuel-efficient in relation to its engine power. The new Turbo S model has an extra 50 hp of power compared with the Cayenne Turbo, as well as torque boosted from 700 to 750 Newton metres, which translates to faster acceleration and a higher top speed. The sprint from 0-62 mph takes just 4.5 seconds (0.2 sec quicker), and the car accelerates to a top speed of 175 mph (+ 2 mph).

The Cayenne Turbo S has been carefully configured for maximum dynamic performance. Therefore, it incorporates all relevant control systems as standard equipment. From the already highly-capable Cayenne Turbo it takes the combination of an air suspension and active PASM damping control. To this is added Porsche Dynamic Chassis Control (PDCC), which reduces the roll angle in curves to improve agility and comfort equally. Porsche Torque Vectoring Plus (PTV Plus) is also a standard feature, combining torque vectoring on the rear wheels with an electronically controlled rear differential lock to improve traction, thereby increasing agility in every driving situation. The new Cayenne Turbo S is also equipped with the Sport Chrono package as standard.

The exterior appearance of the Cayenne Turbo S clearly hints at its purposeful intent. Design highlights include the air inlet grilles, headlight housings and mirrors, which are painted in high-gloss black. The 21-inch diameter ‘911 Turbo II’ alloy wheels with coloured Porsche centre badges are designed exclusively for the Cayenne Turbo S; their inside surfaces also painted in high-gloss black.

Porsche designers created new leather interior packages in fresh colours and patterns specifically chosen for the new Cayenne Turbo S. These interior features are available in Black/Carrera Red or Black/Luxor Beige combinations. The bi-colour leather packages that are reserved for the new top model are extended by adding decorative seams in the contrasting colours Carrera Red and Luxor Beige. The Carbon interior package complements the leather features and highlights the sophistication of both vehicle and materials.

The new Cayenne Turbo S will arrive in Porsche Centres in the UK and Ireland in January 2013, priced from £107,460. Fitted to every Cayenne Turbo S is a Porsche Vehicle Tracking System (VTS), a sophisticated vehicle security package approved to Thatcham Category 5 standard, and customers are also able to explore the potential of their new car by participating in a complimentary course at the Porsche Experience Centre, Silverstone.
