For The diesel V8 engine delivers astonishing performance, yet it’s still capable of 34.0mpg. Equally, the Cayenne is so well engineered it simply scythes through corners faster than any 4x4 has a right to.
Against Despite the V8 diesel Cayenne’s sheer size, and its ability to carry five and their luggage, the cabin does feel quite snug.

Target Price team says:
The basic Porsche Cayenne has a 3.6-litre V6 petrol engine and the range-topper a turbocharged 4.8-litre V8. However, the engines between are the most appealing ones.
If performance is your priority, the V8 S is your best bet: it’s almost as quick as the Turbo in real world driving, yet is massively cheaper.
If you can’t stomach the high fuel bills, there are three other options that are cheaper to run. The 3.0-litre diesel is the most frugal Cayenne averaging 38.2mpg, but it lacks the refinement we expect from Porsche.
A much better bet is the twin-turbo 4.2-litre V8 diesel. It’s smooth, fast and surprisingly frugal. There’s also the Hybrid S, which combines a supercharged 3.0-litre V6 with an electric motor. It can run solely on electric power around town and when you lift off the throttle at speed, helping it return 34.4mpg.
