Porsche has bowed to the inevitable and is now offering a diesel-engined Cayenne SUV.

Due to go on sale in the UK in February, the Cayenne diesel will cost from £40,250.

The engine is the familiar 3.0-litre V6 borrowed from the Audi Q7, returning a claimed average of 30.4mpg and CO2 emissions of 244g/km.

A six-speed Tiptronic S automatic gearbox is fitted as standard.
