That ’s why the pursuit of performance
on the Cayenne S Diesel was not based
on horsepower alone, but also on
efficiency and reduced emissions.
The new 4.2litre V8 turbo diesel has
a high compression ratio and excellent
thermal efficiency. This enables better
use of the higher energy densit y offered by
diesel fuel.
The Cayenne S Diesel features a double
flow exhaust system, with each exhaust
tract comprising an oxidation catalyst
fit ted close to the engine and a diesel
particulate filter. In order to minimise
thermal losses and ensure that the
system is working under ideal condi
tions, the pipes are completely airgap
insulated. Due to the rapid warmup of
the catalytic converters, the optimum
operating temperature is reached earlier
so emissions are reduced sooner when
starting from cold.The exhaustgas recirculation on the
Cayenne S Diesel routes part of the
exhaust gas back into the combustion
process, resulting in lower peak com
bustion temperature and therefore lower
nitrogen oxide emissions.
Lightweight construction is another
key aspect that we are consistently
pursuing. Reduced weight means lower
consumption. This is achieved through
the use of lightweight, innovative
materials – such as aluminium and
plastic – as well as the development
of new production technologies and

for the driver are tangible: greater
agility and impressive driving dynamics
– with enhanced fuel economy. Fuel con
