As well as the downsized turbo engines, the new Porsche’s efficiency should be boosted by less mass: this is the first Cayenne to weigh in at under two tonnes, despite a couple of extra inches (63mm to be precise) in body length and what Porsche says is a marked increase in equipment and features.
The diet is down to more aluminium (not just the body but also the floor pan and most of the chassis), more electrics (including 48-volts) for actuators rather than hydraulics, and lightweight components such as a lithium-ion polymer starter battery. Overall weight reduces from 2,040 to 1,985kg.
With a new tyre set-up – one inch bigger all round, and wider at the back than the front for the first time – and the options of rear-axle steering (from the 911), electronic roll stabilisation and air suspension, the Cayenne is said to be more of a sports car in its sector than ever, while still able to tackle mild off-road routes. Porsche says that all elements of the lightweight chassis are new apart from the Porsche Active Suspension Management (PASM) damper system that is standard with the Cayenne S.
In the braking department, there is the new option of a tungsten-carbide coating for the cast iron discs which Porsche says increases the friction values and reduces wear and brake dust. The calipers do look cool painted white. Another change is to the eight-speed Tiptronic ‘box which gets shorter ratios in the lower gears for a sportier response.
