Let’s forget the future for a moment.
As we discover it in the present.

Engineering.
What use is the engineering of tomorrow
when it can be found on the road today?
None. So let ’s turn to the here and now.
The engines, as you would expect,
are characterised by six horizontally
opposed cylinders. The 3.4-litre engine in
the 911 Carrera and 911 Carrera Cabriolet
produces 257 kW (350 hp); in the
911 Carrera S and 911 Carrera S Cabriolet,
the 3.8-litre engine develops 294 kW
(400 hp). All models are equipped with
direct fuel injection (DFI) and VarioCam Plus
for increased power and reduced fuel
consumption. This power is transmit ted
to the wheels by the new and efficient
7-speed manual gearbox or, optionally, by efficiency-enhanced Porsche

Doppel kupplung (PDK), which offers
gear changes with no interruption
in the flow of power.
Both engines deliver improved sport y
performance compared with the engine
in the previous model and yet fuel
consumption has been reduced by up
to 16 %. How was this achieved? One
explanation is the reduced capacit y of
3.4 litres in the 911 Carrera models.
Another is the total redevelopment of the
engine peripherals with groundbreaking
efficiency-improving technologies. As standard, these include the auto
start/stop function, electrical system
recuperation and intelligent thermal

management as well as the new, energy-
saving electromechanical steering system
and, in the case of PDK, the introduction
of the coasting function (for more
information, please refer to page 43
onwards).
The chassis is also packed with forward-
looking technology. Fitted as standard
in the 911 Carrera S and 911 Carrera S
Cabriolet, Porsche Torque Vectoring
(PTV) increases dynamic performance.
Available as an option for the S models,
Porsche Dynamic Chassis Control (PDCC)
improves dynamic performance further still. Dynamic engine mounts, included as
part of the optional Sport Chrono Package,
are now available in a 911 Carrera for
the first time. These provide perceptibly
more stable handling under load change
conditions and in fast corners.
The new 911 has a light weight composite
construction in aluminium and steel. Used
extensively and in just the right places,
lightweight aluminium improves fuel
economy and dynamic performance and
helps to achieve a low weight to power
ratio of 4.7 kg / kW (3.5 kg / hp) for the
9 11 C a r r e r a S .
The future of the sports car begins now.

911 Carrera models: 390 Nm at 5,600 rpm, 257 kW (350 hp) at 7,400 rpm
The new 3.4-litre engine.
The 911 Carrera and the 911 Carrera
Cabriolet are equipped with a 3.4-litre
boxer engine with direct fuel injection
(DFI) and VarioCam Plus. It develops

257 kW (350 hp) at 7,400 rpm and the
maximum torque is 390 Nm at
5,600 rpm.
For the 911 Carrera with 7-speed manual
gearbox, this means acceleration from
0 to 100 km/ h (0 to 62 mph) in 4.8 sec -
onds and a top speed of 289 km/ h
(179 mph). The figures
achieved by the
911 Carrera Cabriolet
are 5.0 seconds
and 286 km/ h (177 mph). With the
optional Porsche Doppelkupplung (PDK),

it means figures of 0 to 100 km/ h
(0 to 62 mph) in just 4.6 seconds and
a top speed of 287 km/ h (178 mph)
for the 911 Carrera and 4.8 seconds
and 284 km/ h (176 mph) for the
911 Carrera Cabriolet.
The new 3.8-litre engine.
The 911 Carrera S and the 911 Carrera S
Cabriolet are powered by a 3.8-litre boxer
engine with direct fuel injection (DFI)
and VarioCam Plus. It produces 294 kW
(400 hp) at 7,400 rpm and the maximum
torque of 440 Nm is achieved at
5,600 rpm.
As a result, the new 911 Carrera S
with 7-speed manual gearbox completes
the sprint from 0 to 100 km/ h (0 to
62 mph) in
4.5 seconds and reaches
a top speed of 304 km/ h (188 mph). The
911 Carrera S Cabriolet
achieves 4.7 sec -
onds and 301 km/ h (187 mph). With
the
optional Porsche Doppelkupplung (PDK),
the figures are 0 to 100 km/ h (0 to
62 mph) in 4.3 seconds and a top speed
of
302 km/ h (187 mph) for the Coupé and
4.5 seconds
and 299 km/ h (185 mph) for
the Cabriolet.

Electromechanical power steering.
Another possible definition of efficiency
is a system that works only when it is
needed, and then does so in a particularly
effective way.
This was the guiding principle for our
engineers in the development of the new electromechanical power steering.
Statistics show that a car drives in a
straight line 90
% of the time. Unlike
conventional hydraulic pumps, the electric
motor uses energy only when the steering
wheel is actually turned. The absence
of hydraulic fluid also makes the system
more beneficial to the environment.
As far as the other 10 % is concerned, we’re
optimally prepared as the steering system
is t ypically Porsche. It features a variable
steering ratio and responds sensitively
and directly at the same time as providing
customary agility, a high level of comfort
and precisely selected feedback from the
road. Our definition of efficient.Power steering Plus.
Power steering Plus, the comfort-enhancing
power-steering system, is available
as an option for the 911 Carrera models.
At high speeds, the steering is as firm as
you would expect and responds with
extreme precision while steering comfort
remains as high. At low speeds, the steering
ratio of Power steering Plus adjusts for
much easier manoeuvring and parking.
SPORT button.
Fit ted as standard, the new SPORT
but ton enables you to select a suspension
setup where the emphasis is on either
comfort or sport y performance. At the
push of a button, 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 automati
-
cally 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 simultaneous enhancement for
the chassis, engine and transmission.
Every day can be sports day.

Weight is calculated in accordance with the relevant EC Directives and is valid for vehicles with standard specification only. Optional equipment increases this figure. The figure given includes 68 kg for the driver and 7 kg for luggage.2) Data determined in the NEDC (New European Driving Cycle) in accordance with the Euro 5 (715/2007/ EC and 692/2008/ EC) measurement method. The figures do not refer to an individual vehicle nor do they constitute part of the of fer.
They are intended solely as a means of comparing dif ferent t ypes of vehicle. You can obtain further information about individual vehicles from your Porsche Centre. Fuel consumption calculated for vehicles with standard specification
only. A vehicle’s fuel consumption and CO
2 emissions depend not only on its ef ficient use of fuel but also on driving st yle and other non -technical factors. Actual consumption and per formance may var y with items of optional equipment.
