Porsche does not directly state how the power boost is achieved in their press release but it likely follows the Panamera Turbo S. This means upgraded turbos (same casings, new impellers) and a new tune. Options are also standard such as Porsche Dynamic Chassis Control, Porsche Torque Vectoring Plus, and Power Steering Plus.
Is it worth $146,975? In the opinion of PorscheBoost, no. It makes more sense to get a Cayenne Turbo, tune it, and pocket the change. But for people who don't mind the depreciation associated with Turbo S models, this is likely the new performance king of SUV's.
New top model in the Cayenne model range
Porsche Introduces New Cayenne Turbo S with 550 hp
Atlanta. The Porsche Cayenne range is now expanded to include a Turbo S model with 550 hp, an increase of 50 hp from the Cayenne Turbo. The new Cayenne Turbo S sport utility vehicle employs advanced active chassis technologies. These technologies allow it to surpass the driving performance of many sports cars, while preserving the off-road capability, ride comfort and towing ability typical of the Cayenne.
In addition to an increase of 50 horsepower compared to the Cayenne Turbo, the Cayenne Turbo S also benefits from increased engine torque, which is boosted from 516 to 553 pound-feet. This translates into faster acceleration and a higher top speed. The sprint from zero to 60 mph now takes just 4.3 seconds (-0.1 seconds), and the Cayenne Turbo S accelerates to a top track speed of 175 mph (+ 3 mph).
The Cayenne Turbo S is equipped for maximum dynamic performance. Accordingly, it incorporates chassis and drivetrain technologies which are optional on the Cayenne Turbo. More specifically, Porsche Dynamic Chassis Control (PDCC), Porsche Torque Vectoring Plus (PTV Plus), and Power Steering Plus are now standard, in addition to the air suspension with Porsche Active Suspension Management (PASM), which is already standard on the Cayenne Turbo. PDCC allows for even flatter cornering, improving agility and ride comfort. PTV Plus adds torque vectoring at the rear wheels together with an electronically controlled rear differential lock, which improves traction and therefore offers more agility in a wide range of driving situations. The new Cayenne Turbo S is also equipped with the Sport Chrono package as standard, which includes an analog and digital timer located at the center of the dashboard. The performance display informs the occupants about the total driving time, lap distance covered so far and individual lap times. It also shows latitudinal and longitudinal acceleration via the TFT display in the instrument cluster.
The exterior of the Cayenne Turbo S lives up to the high standards of a top model. The front air intakes and rear view mirror trim are painted in high-gloss black. The standard 21-inch 911 Turbo II wheels with colored Porsche badges are exclusively tailored for the Cayenne Turbo S; their inside surfaces are painted in high-gloss black. The wheel arch extensions and rear spoiler separation edge are painted in exterior color. The model also features dual twin-tube sport tailpipes in polished Aluminum.
Porsche designers created an exclusive two-tone leather interior package that is available in either Black/Carrera Red or Black/Luxor Beige combinations. They feature an exclusive combination of contrasting colors and pieces that are further accented by deviated stitching throughout. Front and rear seats feature the Porsche Crest embossed on the headrests while the roof is covered in Alcantara® from front to rear. The instrument panel, door, and center console trim showcase the standard Carbon Fiber interior package that further complements the exclusive interior.
The Cayenne Turbo S is scheduled to go on sale in the spring of 2013 and is priced from $146,000 not including a $975 destination charge.
