Alright, you need a reason to switch to diesel, here’s one. Yep, this here is the Cayenne S Diesel, which now boasts the most pulling power of all the diesel Cayennes – its 4.2-litre twin-turbocharged V8 (as seen – albeit detuned – in the Audi A8) builds up 381hp and 850Nm of torque. Eight HUNDRED and fifty. That’s more than a 911 Turbo S.

 
For a big old unit, it’s pretty quick; 0-100 takes 5.7 seconds, and it’ll go up to 253km/h. Fuel consumption and emissions? A not entirely shabby 12km/L, and 218 g/km CO2, helped by one of those auto start/stop systems (coincidentally, it’s the world’s only V8 diesel SUV to offer one). That lot – and a massive 100-litre fuel tank – means you only have to stop for diesel every 1200km you’re frugal.

 
There’s also a special traction management system that only sends torque to the front wheels when it’s strictly necessary – the rest of the time, according to Porsche, the Cayenne, “delivers the dynamic qualities of a rear-wheel drive car”. Want more sportyness? You’ll need to option the Porsche Torque Vectoring Plus add-on.

 
Outside, it looks just like a petrol Cayenne S. The brake system’s been optimised to handle the car’s power output – note the silver brake callipers. WE SAID NOTE THEM – and the black front intake grilles emphasise the open air inlets.

 
So, ready to give up the title of ‘Petrolhead’? You’ll have to wait till early next year when it goes on sale here.
