Porsche has unveiled a new variant to the Cayenne range, the Cayenne GTS. Set for display at next week's Frankfurt Motor Show, the new SUV is powered by a worked 4.8-litre V8 producing an enormous 298kW (@ 6,500 rpm) and 500Nm (@ 3,500 rpm), which puts the car between the Cayenne S (283kW - 500Nm) and the Cayenne Turbo (368kW - 700Nm).

The GTS accelerates from 0-100 km/h in a staggering 6.1 seconds thanks to its six-speed manual gearbox.

The Cayenne GTS has been lowered by 24 millimeters, and to prove Porsche means business, it is the first Cayenne to feature the electronically controlled damping system, Porsche Active Suspension Management (PASM), with steel springs. Porsche had thus far kept this technology reserved for its sports car range.

The Cayenne GTS comes with Porsche Traction Management (PTM) permanent all-wheel drive and the adaptive PASM chassis as standard, but if that's not enough you can always opt out for air suspension, the Porsche Dynamic Chassis Control (PDCC) active anti-roll system.

On lookers will recognise the GTS as it has a near identical front and rear to the range topping Cayenne Turbo. The car rides on 21-inch alloys with gigantic 295/35 tyres. From the inside, the GTS gets new 12-way sports seats and a leather-Alcantara mix emphasize the sporty interior.

The GTS is also available with a Tiptronic S transmission and comes in two new colours, GTS Red and Nordic Gold Metallic.

Australian details are still unconfirmed, but if it does make it here early next year (and there is no reason why it wouldn't) we expect it to cost somewhere between $134,500 (Cayenne S) and $215,000 (Cayenne Turbo), so most likely around $170,000.
