The new Porsche Cayenne GTS, which makes its world debut at the IAA Auto Show in Frankfurt next week, features a specially developed chassis: it is the first Cayenne to offer the electronically-controlled damping system, Porsche Active Suspension Management (PASM), with steel springs.

This combination, which also lowers the Cayenne by 24mm, was previously reserved exclusively for Porsche sports cars.

The car also boasts an enhanced version of the direct fuel injection (DFI) 4.8-litre V8 petrol engine. The engine in the Cayenne GTS yields 405bhp (298 kW) at 6,500rpm - 20bhp more than in the Cayenne S. Maximum torque remains unchanged at 500Nm at 3,500rpm.

In order to further exploit this horsepower increase, the GTS comes as standard with a six-speed manual gearbox and a shorter axle final drive ratio than the Cayenne S (4.1:1 as opposed to 3.55:1). The Cayenne GTS can accelerate from 0-62mph (0-100km/h) in just 6.1 seconds, precisely 0.5 seconds quicker than the Cayenne S.

The Cayenne GTS can be specified with the Tiptronic S six-speed automatic transmission, in which guise it offers an average fuel consumption of 20.3mpg (13.9 litres/100 km) in accordance with EU standards.

The Cayenne GTS is fitted with Porsche Traction Management (PTM) permanent all-wheel drive and the adaptive PASM chassis as standard.

Air suspension is available as an option, as is the Porsche Dynamic Chassis Control (PDCC) active anti-roll system which enhances the handling and ride comfort.

It comes with newly-developed 12-way adjustable sports seats and a mix of leather and Alcantara upholstery.

The front and rear of the GTS share styling cues with the Cayenne Turbo. The 14mm wheel-arch extensions offer space for the 21-inch alloy rims with 295/35 R21 tyres fitted as standard. Two new colours have also been reserved exclusively for the GTS: GTS Red and Nordic Gold Metallic.

The new Porsche Cayenne GTS will be priced from GBP54,350, including a Porsche Vehicle Tracking System (VTS), a sophisticated vehicle security package approved to Thatcham Category 5 standard, and a Porsche Driving Experience programme. 

The car will be on sale in the UK and Ireland from February 2008.
