Porsche is adding a second diesel model to its Cayenne line-up. Powered by a twin-turbo V8 diesel engine, the Cayenne S Diesel is the company’s foil to the likes of BMW’s X5 M50d and the latest iteration of Range Rover’s TDV8.
The Porsche Cayenne S Diesel utilises a 4,2-litre twin-turbo unit derived from Audi’s TDI equivalent offering in the Q7. Featuring piezo valve-guided common-rail injection and variable-vane turbochargers to minimise lag and offer linear power delivery, this engine develops 280 kW and a stump-pulling 848 N.m of torque that goes some way to explaining this model’s 3 500 kg tow rating.
These outputs are around 100 kW and 298 N.m up on those produced by the current 3,0-litre turbodiesel in the Cayenne Diesel.
Porsche claims a 0-100 km/h time of 5,7 seconds and a top speed of 252 km/h, along with average fuel consumption and CO2 emissions figures of 8,3 L/100 km and 218 g/km – aided by fuel-saving measures such as stop/start technology.
Along with the hike in outputs, the Cayenne S Diesel also ushers in an uprated all-wheel drive system that can be specified with Porsche Torque Vectoring, a system that brakes the vehicle’s inside wheel when tackling sharp bends to aid with sharper turn-in, as an optional extra.
Porsche will also reportedly add this diesel to the Panamera range when the model undergoes a facelift in 2013.
The Porsche Cayenne S Diesel will reach the South African market by the first quarter of 2013.
