Apparently Porsche is not going for a huge powerful diesel either, instead focusing on fuel economy, and has chosen a twin-turbocharged V6.
The engine will reportedly come from Audi and is expected to produce over 300bhp but deliver 30mpg.
Even though Porsche is fighting London mayor Ken Livingstone over an increase in the Congestion Charge it appears the diesel is the company’s attempt to prepare for a worst case scenario.
According to the report the motivation for a Porsche diesel comes from rising worldwide emissions and fuel economy regulation.
If rumours that the hybrid Cayenne is being delayed until 2010 are true that means the diesel model will be the company’s flagship ‘green’ model.
