When it comes to a Porsche, it ’s not
just good looks that mat ter, but what
lies beneath. The engine has been the
character-defining feature of every 911
since
1963. And on the new 9 11 Targa 4
models, it ’s no different. The 6- cylinder
boxer engine, positioned low down at the
rear
of the car, succeeds in uniting t wo
characteristics that are normally mutually
exclusive – performance and efficiency.
Only by doing so is it possible to increase
power output whilst simultaneously
reducing fuel consumption and
CO
2 emissions.
At the heart of all this are intelligent
efficiency-enhancing measures such as
the auto start/stop function and direct
fuel injection (DFI).
And then there’s the crucial weight
factor. The engines are of a light-alloy
construction, making them lightweight
and yet structurally rigid. The result

is comparatively low fuel consumption
and a long service life.
Both engines are also equipped with
VarioCam Plus – a two-in-one engine
concept for adjusting the intake cam -
shafts and switching the lift of the intake
valves. This results in instant accele -
ration, exceptional smooth running
performance and an extraordinary
level of tractive power with a compara -
tively low level of fuel consumption.

The 3.4-litre engine of the
911 Targa 4.
The engine of the new 911 Targa 4
develops 257 kW (350 hp) at 7,400 rpm
and a maximum torque of 390 Nm at
5,600 rpm. When combined with the
7-speed manual gearbox, it accelerates
from 0 – 62 mph in just 5.2 seconds and
reaches a top speed of 175 mph.
The 3.8-litre engine of the
911 Targa 4S.
On the S model, the figures speak for
themselves: the 3.8-litre boxer engine
develops 294 kW (400 hp) at 7,400 rpm
and a maximum torque of 440 Nm at
5,600 rpm. When equipped with the
optional Porsche Doppelkupplung (PDK),
the new 911 Targa 4S completes the
0 – 62 mph sprint in just 4.6 seconds
and can continue on to a top speed of
182 mph.
Efficiency technologies.
At Porsche, reducing fuel consumption is
part and parcel of performance. It goes
without saying, therefore, that efficiency
technologies are standard features on
the 9 11 Targa 4 models and form an
integral part of the vehicle concept.
Whenever the car comes to a stop, the
auto start/stop function automatically
switches off the engine – and restarts it
swiftly and smoothly as soon as you
operate the clutch or, on models with
Porsche Doppelkupplung (PDK), as soon
as you release the brake.
The thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow. The resulting
improvement in combustion efficiency has
a beneficial effect on fuel consumption. A further fuel-saving feature is electrical
system recuperation. This function
ensures that the bat tery is recharged
predominantly by the alternator under
braking conditions.
Direct fuel injection (DFI).
DFI delivers fuel directly into the combus
-
tion chamber with millisecond precision.
The spray and cone angles of the multi-
hole injectors have been optimised for
torque, power output, fuel consumption,
emissions and efficient combustion.
Exhaust system.
The exhaust system of the 911 models
has been redesigned – acoustics included.
The stainless steel exhaust system
comprises two distinctive and independent
exhaust tracts. A selectable t win-tube
sports exhaust system featuring distinc -
tive polished stainless steel tailpipes
is available as an option. Activated by
a but ton, it produces an even more
intensive sports car sound.

SPORT button.
Exceptional design and a sport y character
are not mutually exclusive, as the SPORT
but ton proves. It enables you to select a
suspension setup where the emphasis is
on either comfort or sport y performance.
At the push of a but ton, the electronic
engine management system switches the
engine mapping to offer an even sharper
response and engine dynamics that are
more direct. In vehicles with
Porsche Doppelkupplung
(PDK), upshifts take place at higher
engine speeds and downshifts happen
sooner. In addition, coasting mode

and the auto start/stop function are
automatically deactivated. If fitted, the
optional sports exhaust system is also
activated automatically.
Sport Chrono Package.
The Sport Chrono Package including
dynamic engine mounts is available as an
option. This integrated system provides

engine and transmission. Included in
the package are a performance display,
a digital and an analogue stopwatch and
the SPORT PLUS but ton. An additional
display in the steering wheel and instru
-
ment cluster indicates whether the
SPORT but tons and Launch Control have
been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the new 911 Targa 4S,
the optional Porsche Dynamic Chassis
Control (PDCC) switch to a harder damping set ting and offer more direct steering
and, therefore, better road holding.
In combination with PDK, the Sport Chrono
Package has two additional functions:
‘Launch Control’, which can be used on the
track to achieve the best possible stand -
ing start, and the ‘motorsport-derived
gearshift strategy’ featuring extremely
short shift times and optimum shift
points for maximum acceleration.

In an era of intensifying debate about
global
climate change and CO2 emissions,
every automotive manufacturer is asking
what it has to offer right now. Our answer
is ‘high performance must be accom panied
by high efficiency’.
Exhaust emission control.
Vehicles manufactured by Porsche
demonstrate that even high-performance
sports cars can achieve moderate
fuel consumption and exhaust emission
values in their respective category. This is enabled, on the one hand, by the
use of fuel-efficient technologies such

as auto start /stop, thermal management,
electrical system recuperation, direct
fuel injection or coasting mode. On the
other hand, new cataly tic converters
developed for the 911 provide efficient
emission control through the use of
stereo Lambda control circuitry.
Sustainable driving pleasure
is ultimately a question of good style too.
Porsche and the environment.
Fuel economy and recycling.
Intelligent lightweight construction is
fundamental to the Porsche identit y. It
is expressed through the use of a high
proportion of aluminium, magnesium,
plastics, super-high-strength sheet steel
and environmentally friendly water-based
paints. All materials are meticulously
and purposefully selected. All lightweight
materials are easily recyclable and
all plastic components are labelled to
facilitate their separation for subsequent
recycling. In short, the 911 is now around
95 % recoverable.
Fuel.
All Porsche models – including the 911 –
are designed to operate using fuels with
an ethanol content of up to 10 %, e. g.
‘E10’. Ethanol has a positive impact on
the CO
2 balance since the plants grown
for the production of this biofuel also
absorb CO
2 from the atmosphere.
