alternator PORSCHE CAYNNE 2011 2.G Information Manual

The 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, economical
driving st yle while offering
exceptional reserves of power.
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
compact dimensions and high
levels of efficiency. It also acts as

a starter motor and alternator.
Working in tandem, both units
provide a total output of 279 kW
(380 hp) and maximum torque
of 580 Nm, propelling the car
from 0 to 100 km/ h (62 mph) in
just 6.5 seconds. These are the
levels of acceleration you would
usually expect from an eight-
cylinder unit, but with fuel con-
sumption 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 electronic engine manage-
ment system receives all infor-
mation on the driving and energy
status and controls both drive
systems to ensure optimum per-
formance in any driving scen ario.
racecar with great potential for
the future.
With the Cayenne S Hybrid, our
primary focus was on meeting
customer requirements in
terms of athleticism and greater
everyday practically. The result:
the parallel full hybrid.
The drive system of the
Cayenne S Hybrid.
Hybrid drives are suitable for use
in a wide range of scenarios. On
road, of f road or on the track – to
us, it ’s about using technology in
the most intelligent way. Porsche
Intelligent Performance has
enabled us to introduce hybrid
technology into a variet y
of different vehicle concepts.

The clearest proof of this is the
super sportscar of the future –
the 918 Spyder. The electric
machines in its plug-in hybrid
system work in conjunction with
the high rpm engine to deliver
exceptional performance with
incredibly low fuel consumption.
Another example is the 911 GT3 R
Hybrid. With its front-wheel hybrid
drive and fly wheel storage sys-
tem, it is an extremely modern
interpretation of a thoroughbred
Hybrid, diesel, petrol. Many different options.
One outcome: Porsche.

It shuts of f the combustion
engine and switches it back on.
Thanks to the ultra-fast decoup-
ler and instantaneous engine
start-up, all of this goes un-
noticed by the driver.
Under mod-
erate
acceleration, the electric
machine can power the vehicle
independently using electricit y
alone. For example, for driving
quietly through residential areas
.
In
addition, it can be used to
boost
performance – for even
faster acceleration.
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 automatically disengaged from
the drivetrain and shut off: 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, when heading out of a
residential area, for instance.
The throt tle map is adapted 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
console.
