The first three versions of the new Porsche Cayenne are now available to order in Australia, starting at $116,300 before on-roads.

But that’s just for the standard Cayenne with a 3.0-litre turbo V6 under the bonnet. That model produces 250kW and 450Nm, already more than most SUV drivers would need on a daily basis.

But the Cayenne S, priced at $155,100, adds a turbo (though this engine is a 2.9-litre), and with it comes an extra 74kW and 100Nm for 324kW/550Nm all up.

Moving to the top of the food chain, for now, is the Cayenne Turbo.

Thanks to the Porsche Panamera, it scores a 404kW/770Nm twin-turbo 4.0-litre V8 capable of launching the 2175kg mammoth to 100km/h in just 4.1 seconds, or 3.9 with Sport Plus.

It seems steep, but it’s cheaper and faster (Porsche says) than any of the twin-turbo V6-powered Panameras.

It also reaches a top speed of 286km/h, a speed few would be brave enough to hit in an SUV.

First deliveries are expected to arrive locally in mid-2018.
