The model, which celebrates its world debut at the IAA in Frankfurt, features an enhanced 4.8-liter V8, has been lowered by 24 millimeters and has a specially developed chassis: it is the first Cayenne to feature the electronically controlled damping system, Porsche Active Suspension Management (PASM), with steel springs. This combination was previously reserved exclusively for Porsche sports cars.
The 4.8-liter engine with direct gasoline fuel injection (DFI) in the Cayenne GTS yields 405bhp (298 kW) at 6,500 revolutions per minute – 20bhp more than in the Cayenne S. Maximum torque remains unchanged at 500Nm at 3,500 revolutions per minute.
This, the sportiest of Porsche SUVs, comes as standard with a six-speed manual gearbox and a shorter axle drive ratio than the Cayenne S (4.1:1 as opposed to 3.55:1). The Cayenne GTS can thus accelerate from zero to 100km/h in just 6.1 seconds, precisely 0.5 seconds quicker than the Cayenne S.
The Cayenne GTS is fitted with Porsche Traction Management (PTM) permanent all-wheel drive and the adaptive PASM chassis as standard. As well as optional air suspension, the Porsche Dynamic Chassis Control (PDCC) active anti-roll system is available to enhance handling and ride comfort. Newly developed 12-way sports seats and a leather-Alcantara mix emphasize the sporty interior.
The new Cayenne GTS is instantly recognizable: the front and rear look the same as the Cayenne Turbo, and the striking 14mm wheel-arch enlargements offer plenty of space for the standard 21-inch alloy rims with 295/35 R21 tires. Two new colors have also been reserved exclusively for the GTS: GTS Red and Nordic Gold Metallic.
The new Cayenne model with Tiptronic S transmission has an average consumption of 13.9 liters/100 km in accordance with EU standards. Global dispatch will start in February 2008. In Germany it will cost 76,725 Euros including 19 percent VAT and country-specific requirements; the base price is 64,300 Euros. The base price for the USA (MSRP USA) is US $69,300.
