Porsche has added a diesel S version to its upmarket SUV range, the Cayenne, and they should be available in New Zealand around March/April next year.

Pictured above ahead of a planned world premiere at the Paris motor show at the end of this month, the new Cayenne S Diesel runs the latest evolution of Volkswagen sister company Audi's 4.2-litre V8 diesel engine.

With twin variable-vane turbochargers and the latest in common rail injection technology, the 90-degree unit kicks out 281kW and 850Nm of torque - an increase of 105kW and 300Nm on the existing single turbocharged 3.0-litre V6 diesel engine found in the existing Cayenne Diesel. 

By way of comparison, the Cayenne S Diesel's keenest rival, the recently introduced BMW X6 M50d, boasts 280kW and 740Nm from its BMW M division developed triple-turbocharged 3.0-litre in-line six-cylinder diesel engine.

According to Porsche's own performance figures, heady reserves are sufficient to haul the four-wheel-drive Cayenne S Diesel from standstill to 100km/h in just 5.7 seconds and to a top speed of 252km/h. Yet despite the increase, towing capacity remains the same as the lesser Cayenne Diesel at 3500kg.

Equipped with various fuel saving features, including automatic stop/start, the latest of Porsche's second-generation Cayenne models is also claimed to return 8.3L/100km on the combined European consumption cycle, providing it with a theoretical range of up to 1200km on its standard 100-litre fuel tank along with average CO2 emissions of 218g/km.

As with rival BMW and its new M-Performance diesel engine, Porsche says it has worked hard at providing the new V8 diesel, which is also earmarked to join a facelifted Panamera line-up in 2013, with a distinctive sound, which it likens to its more traditional V8 petrol units.

The strong torque qualities of the big diesel have also led to a unique set-up for the Cayenne's four-wheel drive system, with torque vectoring set to be offered as optional equipment.

The Cayenne S Diesel receives the same styling treatment as other V8-powered Cayenne models along with diesel badges on the front flanks and Cayenne S identification on the tailgate.

New Zealand pricing for the Cayenne S Diesel has yet to be finalised. However, currently, a Cayenne Diesel is listed at $140,500 and the Cayenne S at $183,500.
