The new Porsche Panamera diesel carries over the existing Audi-sourced 3.0-litre V6 turbo-diesel engine, albeit revised with a new crankshaft drive, pistons and new water-cooled turbocharger, to produce of 221kW at 4000rpm and 650Nm between 1750 and 2500rpm – up 37kW and 100Nm on the current model.
Powering the rear wheels through a re-tuned eight-speed Tiptronic S automatic transmission, with shorter ratios for the first four gears, the refreshed oil-burning Panamera claims 0-100km/h in six seconds and a top speed of 259km/h – 0.8sec quicker than its predecessor with 15km/h more top end.
Economy is also improved, with Porsche claiming a 0.1L/100km and 3g/km CO2
improvement to 6.4L/100km and 169g/km.
Along with towing capacity being increased by 100kg to 2600kg, the German manufacturer has also added its torque vectoring system – which distributes engine torque to the rear wheels and electronically controlled rear differential by applying brake pressure to individual wheels – standard for the first time. More rigid front and rear anti-roll bars have also been added in a bid to improve the 1880kg luxury four-door's agility.
Like the facelifted Panamera plug-in hybrid, 3.0-litre petrol and long-wheelbase variants seen in April, the revised diesel gets new LED headlights, larger air intakes and new tail-lights. The model should also benefit from an upgraded active cruise control system and lane departure warning.
The new Porsche Panamera Diesel is due to arrive in Australia from March 2014, priced from $204,600 – up $7900 over the current model’s $196,700 price tag.
Complete specifications are expected to be announced closer to the car’s local launch.
