More power to Porsche

NT News - Motoring - - CARS GUIDE - By NEIL DOWLING

FOR a car maker that five years ago dis­missed the no­tion of a diesel model, Porsche is now a con­vert.

Up­ping the ante with a 281kW/850Nm bi-turbo diesel V8, Porsche’s new Cayenne S — due here in April — smacks back at BMW’s X5 M50d and looks to tackle the 2013 Range Rover Sport 4.4-litre V8 diesel.

Bor­row­ing the Volk­swa­gen fam­ily’s 4.2-litre V8 diesel — fit­ted to the Touareg and Audi A8— and boost­ing out­put by adding a sec­ond tur­bocharger may pro­vide the am­mu­ni­tion to take on ri­vals.

Porsche said its next Cayenne would be ca­pa­ble of a 0-100km/h time of 5.7 sec­onds and fuel con­sump­tion of 8.3L/100km. Un­like its V6 diesel si­b­ling, the V8 will have a stop-start sys­tem to im­prove fuel econ­omy.

It has a 100-litre fuel tank and can be driven up to 1200km be­tween re­fills. Porsche says the V8 diesel ‘‘is typ­i­cally Porsche, com­bin­ing an emo­tional V8 engine sound with punchy, smooth per­for­mance’’.

The Cayenne S Diesel has ac­tive all-wheel drive that is tuned to give driv­ing qual­i­ties of a rear-wheel drive.

Op­tional Porsche Torque Vec­tor­ing Plus (PTV Plus) adds fur­ther han­dling dy­nam­ics. The V8 is rated to tow up to 3.5 tonnes. The SUV shares its ex­te­rior and hard­ware with the V8 petrol Cayenne S. It has an up- graded brake sys­tem — iden­ti­fied by sil­ver brake calipers — to han­dle the ex­tra out­put and weight.

Other dis­tin­guish­ing fea­tures are black fins at the front to em­pha­sise the spoiler’s air in­lets. It also has ‘‘diesel’’ badges on the front guards and ‘‘Cayenne S’’ badges on the tail­gate. The Cayenne S Diesel is $155,500 and goes on sale in Aus­tralia in April 2013. This com­pares with the on­go­ing V6 diesel that is priced at $110,400.
