Like us, you’ve probably already dis
covered the t wo vital ingredients you
need to achieve any goal: endurance
and performance.
In the Cayenne S Diesel beats the heart
of a pure bred athlete. The smooth
running 4.2 litre V8 turbo diesel engine is
both efficient and extremely powerful.
Generating 281 kW (382 hp), it enables
the car to sprint from 0 to 100 km/ h
(62 mph) in 5.7 seconds and reach a top speed of 252 km/ h (156 mph).
Maximum torque is an impressive
850 Nm, while fuel consumption comes
in at just 8.3 l/100 km (34.0 mpg) in
the combined test cycle.

The highest performing V8 turbo diesel
in its class, it is assisted by t win turbo
charger units arranged in parallel – one
for each bank of cylinders. Incoming air
is passed through a shared filter and
compressed by the turbine units. Its
temperature is then reduced in the t win
intercooler system before it is fed
through to the engine.
Direct fuel injection comes courtesy
of a common rail injection system. The
piezoelectric injectors enable multiple
injections at a pressure of up to 2,000 bar,
ensuring optimum distribution of the air/
fuel mixture – for smooth running com
bustion.
As you’d expect from a diesel, efficiency
levels are high. This is due to advanced
technologies such as the standard auto
start/stop function. The turbochargers
on the Cayenne S Diesel also feature
Variable Turbine Geometry (VTG). Thermal management ensures that
the optimum operating temperature
for the engine and transmission is
reached more quickly. This reduces
fuel consumption and CO
2 emissions.
The key to success: being able to
stay the distance.

Our aim is to help you move forward –
now and in the future.
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
