THE LATEST PORSCHE Cayenne S Diesel has a 4.2-litre twin-turbocharged V8 engine delivering an astonishing 850Nm of torque, and 371bhp, offering it the most pulling power in the range. It also has a claimed 34mpg and 218g/km CO2 emissions figure, while still managing a very rapid 0-62mph in only 5.2 seconds. Porsche believes that this is the only SUV V8 diesel in the world to offer such figures. The Cayenne has the Porsche Traction Management (PTM) system which means the vehicle has rear-wheel drive handling characteristics – in keeping with the company’s sports car image – while driving the front wheels as and when traction is demanded. The optional Porsche Torque Vectoring Plus (PTV Plus) ‘further hones this dynamic performance’. We hope to get behind the wheel of this new Cayenne soon, to find out exactly what that means. The model will be available in the UK from January 2013,with a basic starting price of £58,243.
