Working in tandem, both units
provide a total output of 279 kW
(380 hp) and maximum torque
of 580 Nm. The new Cayenne S
Hybrid is propelled from 0 to
100 km/ h (62 mph) in 6.5 sec
onds. These are the levels of
acceleration you would usually
expect from an eight cylinder unit,
but with fuel consumption of
under 8.2 l/100 km (34.4 mpg)
in the EU cycle.

On the parallel full hybrid system,
the electric machine is integrated
directly into the drivetrain. The
hybrid module is situated bet ween
the transmission and the com
bustion engine. The engine is
engaged and disengaged using
a specially designed decoupler.
The complex interplay bet ween
combustion engine, decoupler,
electric machine and bat tery is
controlled by the electronic engine
management system. It receives
all information on the driving and
energy status and controls both
drive systems to ensure optimum
performance in any driving scen
ario. It shuts of f the combustion
engine and switches it back on.
Thanks to the ultra fast decoupler
and instantaneous engine start
up, all of this goes unnoticed
by the driver.
Under moderate
acceleration, the electric machine
can power the vehicle independ
ently. For example, for driving
quietly through residential areas
using electricity alone. In
addition, it can be used to boost
At 288 Volts, the electric machine
has a maximum output of
34 kW (47 hp). The benefits of the
synchronous motor with inner
rotor design are extremely com
pact dimensions and high levels
of ef ficiency. It also acts as a
starter motor and alternator.
The drive system of the
new Cayenne S Hybrid.
The abilit y to balance the dynamic
interplay of forces has a name:
hybrid drive. The combination
of internal combustion engine
and electric machine has led to
a significant reduction in fuel
consumption. We have opted
for a solution that satisfies our
requirements perfectly: the
parallel full hybrid.
The new Cayenne S Hybrid has a
3.0 litre V6 supercharged engine.
The charging effect of the
compressor ensures high levels
of torque, even at low engine
speeds. The unit generates an
output of 245 kW (333 hp).
440 Nm of torque is available
bet ween 3,000 and 5,250 rpm,
enabling a low rev, economic
driving st yle while offering
exceptional reserves of power.

performance – for faster
acceleration, particularly when
pulling away.
The parallel full hybrid concept
also comes into its own during
performance driving. When
the Cayenne S Hybrid is driven
at high speeds and on overrun,
the combustion engine is auto
matically disengaged from the
drivetrain and shut of f: the car
continues to ‘coast’ along.
Engine drag and the associated
losses are eliminated and efficiency is increased at speeds
of up to 156 km/ h (97 mph).
The ‘e power’ function expands
the range in which the vehicle
can be run solely on electric
power. The throt tle map is adapt
ed so that the combustion engine
is engaged later than in ‘Normal’
mode depending on performance
requirements. This is activated
via a but ton on the centre con
sole.
