911 Carrera

For us, developing a

911 will forever be an

obligation. To our roots.

To individuality. And,

naturally, to sportiness.

Nevertheless, our efforts

in development do not

concern themselves

solely with the hunt

for the highest horse-

power, but with the

search for efficiency.

In fact, the 911 gives

much and takes little.

Another sign of

inner strength.

Harmony between driver and the 911.

Harmony with the environment as well.

In an era of intensifying debate

about CO

2

emissi ons, every

automotive manuf acturer is being

aske d the question, “What is

your ans wer to the issue

of fuel consumption?” Our

ans wer has long been the

same: maximum efficiency.

Over the last 15 years, Porsche

has reduced the CO

2

emissions

of its vehicles annuall y by an

average of 1.7 percent. As far

as engine o utput is concerned,

we are already among those

manufac turers achieving the

lowest CO

2

emissions. This

has been

achieved through the

efficient Direct Fuel Injection

(DFI),

lightweight constructi on,

optimal aerodynamics and

low rolling resistance.

This high level of environmental

re sponsibility is clearly

demonstrated by our approach

to environmental manage ment

at t he P orsche de ve lopment

center i n Weissach. Here, all

technological develo pments are

carried out with

environmental

protection in mind. The goal?

Pure performance—

but not at

th e expen se of the environment.

The result? The 911. Find out

Exhaust emissions control.

Both 911 engines comply with

stringent e missions stand ards ,

including Euro 5 in Europe

and LEV II in the USA. Vehicles

manufactured by Porsche

demonstrate that even high-

performance sports cars can

achieve moderate emissions

values in their respective

categories. Indeed, not only

is the 911 one of the most

exciting cars around, but it is

also one of th e cleanest.

This is achieved through the

use of a two-stage cascade-

type c atalytic c onverter which

com prises two monoli th

substrates on each of the twin

exhaust tracts. These specially

coated substrates co ntain ultra-

f ine hone ycomb channels in

which pollutants are converted

as exhaust gas passes

through.

The stereo Lambda Sensor

®

circuitry contr ols and monitors

each cyl inder bank

separately,

while another Lambda Sensor

®

on each cylinder bank monitors

pollutant conversion in the

respective c atalytic converter.

Fuel economy and recycling.

At Porsche, a fundamental aspect

of desi gn is i ntelligent lightweight

co nstruction. For both economical

and ecolog ical reasons. This

forms the basis for low fuel

co nsumption values in conjunction

with outstanding performance.

It is economical , thanks to the

high proportion of aluminum

cast allo ys, magnesi um, plastics

and super high-strength sheet

steel used. This i s substantially

more stable and lighter than

conven tional steel. In the 911

models, appr oximately 20

percent of components is

made from lightweight a lloy s.

It is also ecological because all

materials used are meticulous ly

selected. We use only innovative

and environmentally friendly

com ponents. All lightweight

materials are easily recyclable

and each material is labeled

to facilitate it s separatio n for

recycling. The reduction in

the number of plastic variants

helps to ensure more efficient

recycling. Recycle d plastics

are used where they meet our

ex acting technical requirements.

This all combines to make the

current 911 approximately

95-percent recyclable.

In addition, Porsche prima rily

uses environmentally friendly

water-based paints. The 911 is

absolutely free of asbestos, CFCs

and components man ufactured

using CFCs. This is because,

here at Porsche, environmental

protection does not be gin at

the end of a vehicle’s life.

It starts at the p lanning and

development stage.

Fuel.

The 911 is already designed to

ope rate on fuels with an ethanol

content of up to 10 perce nt.

Ethanol has a positi ve impact

on t he CO

2

balance since the

plants grown for the production

of this biofuel also absorb

CO

2

fro m the atmosphere.

The release of hydrocarbons

from t he fuel system is minimal.

This is achieved through an

active carbon filter and a specia l

coating on the fuel tank. All fuel

lines are made from aluminum

and laminated plastic .

Noise.

The 911 complies with all

applicable noise regulations

withou t any form of engine

encapsulation. To achieve

this, noises are eliminated at

sou rce. Engine parts are stiff,

moving part s are lig htweight

and tolerances a re kept to

a minimum. Large-volume

silencers and reson ators in

the air-intake system minimize

noise further. For the entire

service life of the v ehicle.

Servicing.

Long service intervals offer

clear advantages. For you:

lower c osts and saved t ime.

For the environment: the

use of fewer consumables

and replacement parts.
