Road test: Porsche Cayenne S Hybrid

Martyn Collins

Owning a big, powerful car is definitely not PC in these green car-buying times. Porsche's solution for green-conscious SUV owners is this hybrid version of their second-generation Cayenne.

A first for Porsche, I tried this £70,597 S version for a week to see how green it actually is and whether it offers an alternative to the established Lexus RX400h as a green SUV.
