PORSCHE has opened the order book for its new Cayenne, arriving in Australia in a couple of months.

The three-model range of the sports SUV starts with the Cayenne, priced from $116,300, the Cayenne S from $155,100 and then thereโ€™s a big jump to $239,400 for the Cayenne Turbo.

Based on the concept of the iconic 911 sports car,ย  the Cayennes have a new design, new eight-speed Tiptronic S gearbox, new chassis systems, innovative display and control concept with total connectivity plus active aerodynamics take sport and comfort to the next level.

Under the bonnet of the standard model is a 250kW/450Nm turbocharged 3.0 litre V6.

The Cayenne S is powered by a biturbo 2.9-litre V6 that puts out 324kW/550Nm while the Turbo is driven by a 4.0 litre eight-cylinder with two turbochargers, generating 404kW and 770Nm.

The extra muscle has improved acceleration and top speed.

For what itโ€™s worth in our โ€˜speed killsโ€™ society, the Cayenne accelerates to 100 km/h in 6.2 seconds and achieves a top speed of 245 km/h.

The Cayenne S can get to 100km/h in 5.2seconds and on to a top of 265km/h, and the big Turbo can stop the sprint to 100km/h in 4.1 seconds and run to 286km/h.

The third edition of the model has mixed tyre sizes and optional rear-axle steering for the first time.

Standard fare in Australian models will include ParkAssist with surround view, and Lane Change Assist as standard.

The S and Turbo models also come with a panoramic sunroof and the Turbo specs include ambient lighting, seat ventilation and four-zone climate control.
