INSERT PICTURE OF CAYENNE DIESEL
2009-2010

When the Cayenne was launched, Porsche was adamant that they wouldn’t produce a diesel but, not surprisingly, they had to bow to market forces and offer one.

The exterior was the same as the petrol V6 but at the heart of the car was a 3.0-litre V6 turbocharged diesel engine producing 240bhp and a heady 550Nm of torque at just 2000rpm.

Combustion air was supplied by a turbocharger with variable geometry and an intercooler positioned further downstream. As on the 997 Turbo, the turbocharger featured adjustable blades that varied the flow of exhaust gas to the turbine wheel.

At low engine speeds the adjustable guide blades allowed high torque and ensured a good response by guiding the flow of exhaust gas at full pressure to the turbine wheel. At high engine speeds, the turbine blades served to minimise fuel consumption and exhaust emissions by opening up to reduce exhaust gas counter-pressure.

The advantage of the engine was its economy, with Porsche quoting 30.4mpg in the NEDC (New European Driving Cycle), giving the car a range of up to 620 miles on its 100 litre tank.

Extra sound deadening helped isolate passengers from the sound of the engine, including a special windscreen.

In other ways, the specification and options were similar to those of the petrol-engined V6.
