Following the 'eco' SUV trend, the new Cayenne is lighter and more efficient than the car it replaces, coming with both a diesel and, for the first time, a Hybrid version. A near 200kg weight drop is mainly due to simplifying the transmission, which no longer comes with a low ratio 'box.
Prosche's Hybrid Cayenne comes with a supercharged 3.0-litre V6 offering 34.4mpg, and emits only 193g/km CO2. Its 'leccy motor, sandwiched between the engine and gearbox, moves the power output to 375bhp and torque to 427lb ft. The hybrid can run on electric power only (albeit for a short time) up to 40mph.
It's worth noting that the Cayenne accounts for 50 per cent of Porsche sales, so a hybrid emitting less than 200g/km is going to do wonders for the brand's averages.
Diesel power returns with 20per cent better fuel economy, while the 240bhp V6 will now achieve 38.2mpg and 195g/km.
The 395bhp 4.8-litre V8 Cayenne S returns 15bhp more than before, though it also 'only' uses 26.9mpg on the combined cycle.
Prices start at £41,404 for the V6 Cayenne and shoot up to £81,589 for the Turbo.
