The 3.4-litre engine.
The 911 Carrera base models 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 62 mph in 4.8 seconds and a top
speed of 179 mph. The new 911 Carrera 4
accelerates to 62 mph in 4.9 seconds
and has a top speed of 177 mph.

The 3.8-litre engine.
The 911 Carrera S models 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. With optional Porsche Doppelkupplung
(PDK), the 911 Carrera S accelerates
from 0 to 62 mph in 4.3 seconds and
achieves a top speed of 187 mph.

The new Carrera 4S completes the
0 to 62 mph sprint in 4.3 seconds and
boasts a top speed of 184 mph.

Engines
Integrated dry-sump lubrication.
Integrated dr y ­sump lubrication ensures
a reliable supply of oil even when a
sport y driving st yle is adopted. It also
has additional cooling functions.
The oil tank is located in the engine,
thereby eliminating the need for an
external oil tank, which saves both space
and weight. To reduce power loss and
increase efficiency, an electronically
controlled oil pump supplies the lubricat ­
ing points inside the engine as and
when required. When demand is low, the
oil pump is operated at reduced power,
thereby saving fuel.
Air intake system.
The resonance intake system increases
the intake volume by exploiting the fact
that air oscillates as it passes through
the intake manifold. The system can
adjust to engine speed. Benefits of this
include higher torque at low engine
speeds and a flat ter torque curve.
The
9 11 Carrera S models operate a t wo ­
stage
system.
The entire intake system is made from
light weight plastic. In the 9 11 Carrera
model range, the resonator volume of
the air filter housing varies with engine
speed to bring added character to the
engine sound, which becomes much
more powerful at higher rpm.
Exhaust system.
The exhaust system of the 911 Carrera
models has been redesigned, acoustics
included.
The stainless steel exhaust system com ­
prises t wo distinctive and independent
exhaust tracts. The cataly tic converters
heat up rapidly for effective emissions
reduction.
A selectable t win ­tube sports exhaust
system featuring distinctive polished
stainless steel tailpipes is available as an
option. Activated by a but ton, it produces
an even more intensive sports car sound.
Engine management system.
The EMS SDI 9.1 engine management
system ensures optimum engine perfor ­
mance at all times. It controls, for
example, the position of the electronic
throt tle valve (ETC) – a prerequisite for
compati bility with the Porsche Stability
Management (PSM), which comes as
standard. It also regulates all engine ­
related functions to achieve optimum
fuel consumption, emissions and power
output whatever the driving st yle.
Another function is the cylinder ­specific
knock control. Since the cylinders never
all work under exactly the same condi ­
tions, the knock control function monitors
each one separately. The ignition point
is shifted individually, as and when
necessary, to protect the cylinders and
pistons at high engine speeds.
For compliance with EU standards, the
on ­board diagnostics detect any faults
and defects that may occur in the exhaust
and fuel systems and then notify the
driver immediately. This also prevents
increased pollutant emissions and
unnecessary fuel consumption.

Anti-theft protection.
All 911 Carrera models are equipped as
standard with an immobiliser with in
­key
transponder and an alarm system with
radar ­based interior surveillance. The
system secures the doors, luggage com ­
partment, passenger compartment and
ignition lock.
Preparation for Porsche Vehicle
Tracking System (PVTS).
Available as an option, this preparation
enables future installation of the Porsche
Vehicle Tracking System (PV TS) available
from Porsche Tequipment. The system
makes it possible to locate a stolen
vehicle across most of the countries
of Europe. The preparation package
includes a special wiring loom and a

tilt sensor for the alarm system.
Luggage compartment.
The luggage compartment volume in the
911 models is 145 litres – 125 litres on
the 911 Carrera all ­wheel ­drive models.
The luggage compartment is fully trimmed
in scratch ­resistant materials.
Roof transport system.
Available as an option for the Coupé
models, the roof transport system in
aluminium is aerodynamically efficient,
very light weight and easy to fit. A range
of at tachments is available, such as a
roof box, a bike carrier or a ski/snowboard
carrier. Maximum roof load is 75 kg.
Porsche Entry & Drive.
With the optional Porsche Entry & Drive,
you can leave your car key in your pocket.
As soon as you grab the door handle
or approach the luggage compartment,
the system automatically checks the
encrypted access code on the key. Once
the key is validated, the door or the luggage compartment lid unlocks. The
engine can then be started and switched
off using the electronic ignition switch.
To lock the vehicle, you simply press the
but ton on the outside of the door handle.
Porsche Entry & Drive then locks the
vehicle and activates the engine immobi
­
liser and steering column lock.
