Fuel consumption has also been improved upon, with the big SUV now burning only 7.2 liters of diesel per 100 km (39 mpg). At the same time, CO2 emissions have dropped six grams to 189 g/km. That puts the diesel version back in pole position as the most economical Cayenne with the lowest carbon emissions.
The added power has also had an effect on performance! For example, the acceleration time from 0 to 100 km/h (62 mph) has been cut to 7.6 seconds (minus 0.2 seconds) with top speed increasing to 220 km/h (137 mph). It looks like the V6 diesel is once again the engine to have if you want a good balance from your Cayenne.
“The improvements have been achieved through a package of measures, from the use of new materials to reduce weight, lower frictional resistance to a revamp of the injection system, along with a new turbocharger and enhanced thermal management. In detail, the crankshaft for example has been redesigned; fewer counterweights and hollow bores make it lighter and thus more free-revving than before,” Porsche says.
The variable geometry turbocharger is also a new design and has optimized bearings and a new compressor wheel, which translates into improved response and greater efficiency. The package of measures also sliced 20 kilograms off the weight of the V6 engine. That sounds a bit boring but weight reductions and power increases make for a good mix.
