As a global, pioneering leader in tech-
nology, MAHLE has aligned its corpo-
rate organization to the growing re-
quirements of international markets.
With these structures, we can offer
our customers working on global plat-
forms and projects across continents
more performance, more benefits,more synergies and more service for
integrated systems solutions.
Autom ob ile m anu facturers are placing in-
creasing em pha sis o n c oop eration for the
joint use o f platform s and eng ines. So-
called w orld engines are often produ ced
in d ifferent reg ion s an d cou ntries. At the
sam e tim e, the n um ber of interfaces and
sup pliers is decreasing w hile sub -process-
es and produc ts are being o utsourced
through increasing use o f m odu les and
system s. This develop m ent calls for glo-
ba lly active supp liers w ith a presence in
all regions, com bined w ith extensive tech-
nical and financial potential.
Global reach plus proximity to the
customer
Ag ainst this bac kgroun d, we h ave re-
aligned our corporate organ ization to be

redu ction of interfaces, sign ificantly sim pli-
fied com m unication and po sitive e ffects, in
pa rticular for large projects realized across
Produ ct Lines or cou ntries. Thank s to o ur
global sales o rganization, we are in a per-
fect position to fulfill the future req uire-

MAHLE plus Cosworth Technology
equals MAHLE Powertrain. An equa-
tion with tangible results for our
customers. At the beginning of 2005,
MAHLE acquired the Cosworth Tech-
nology Group with its expertise gained
since 1958 in the area of development
and production for road-going high-
performance engines. (Not to be con-fused with Cosworth Racing, now
Cosworth Ltd., the manufacturer of
Formula 1 engines). Successful inte-
gration in the MAHLE Group and re-
naming to MAHLE Powertrain on July
1, 2005 has enabled us to substantial-
ly extend our international engineering
and systems competence.
Power for the future
As a system s pa rtner, w e aim to fully uti-
lize future p otentials bo th ec onom ically
and techno log ically for our custom ers and
m ake e ngines e ven m ore efficient: op ti-
m ized for m ore pow er, long er service
lives, reduc ed fuel consum ption and low er
em issions. W ith M AH LE Pow ertrain, we
offer exp ertise and exp erienc e, w hich
exten d far beyo nd their origin in the field
of developing high-perform ance engines.
The com petence of M AH LE P ow ertrain
covers a broad spectrum from engineering
services o r integrated prototype h ardw are
and so ftw are for the entire pow ertrain
through to the developm ent of com plete
eng ines and their production. O ur glob alM AH LE sales and developm ent netw ork
allow s us to u tilize w orldw ide synergies for
inno vative so lutions. M AH LE Po w ertrain
has four locations for the d evelopm ent,
production a nd assem bly of engines: The
tw o developm ent centers in N ortham pton
(U K) and N ovi near Detroit (M I/US A) are
integrated in joint projects in the M AH LE
research an d d evelopm ent activities, and
w ork together w ith the o ther five d evelop-
m ent centers of the M AH LE G roup. The
two p roduc tion locations in W orcester (U K)
and W ellingb orough (U K) are respon siblefor the casting, prod uction a nd m ach ining
of cylinde r heads and engine blocks as
w ell as engine a ssem bly for sm all lots. The
first Au di R S4 and R S6 engines as w ell as
the Aston M artin V 12 eng ines, for instance,
all had their origin here and the A ud i/VW
V6 2.4 and 2.8 liter engines also c om e o ff
the p roduction line at this site.
Design, Research and Development
Today M AH LE Po w ertrain w ork is involved,
am ong st other things, w ith e xhaust em is-
sions a nd drivability of eng ines, fuel savingcon cep ts, diagno stics as w ell as the
redu ction of developm ent tim es from the
conc ept and p rodu ction through to dea ler
supp ort. This allow s M AH LE Po w ertrain to
offer a w ide range of services from
sho rt-term prototype p rojects through to
com plete engine program s w ith self-de-
velop ed eng ine c onc epts including the
prod uction an d develop m ent of electronic
diagno stics. The e xpe rienc e ga ined in the
area of com bustion engines extends from
one-cylind er to V1 2 a nd all variants in be-
tw een. Com puter-aided developm ent and
ana lysis processes enable rapid and cost-
effective designs, w hich ca n be verified
later in relation to com po nents or in the
entire eng ine w ith va riou s test facilities.
For this purpose, M AH LE P ow ertrain has
18 fired eng ine test bench es an d four
vehicle cha ssis dynam om eters. In ad dition
to pow er and torque be havior, the entire
em ission sp ectrum can also be recorded
and certified . This is of particular b enefit
to our custom ers in rega rd to stricter
exhau st gas regulations due to b e im ple-
m ented in the future.
Production and assembly through to
the complete engine
Besides com ponents, M AH LE P ow ertrain
also produ ces its ow n co m plete engines.
This includes casting and m ach ining cylin-
der crankcases and cylinde r heads w ith
series prod uction o f up to 120 ,00 0 un its
each year. At the sa m e tim e, our exten-
sive eng inee ring expe rienc e ensures that
each solution w e de velop is also optim ized
for prod uction in its d esign. M oreove r, we
also o ffer our custom ers the c om plete
assem bly of eng ines tested and deliv-
ered read y to install. Th anks to its broad
range o f services and the effective co m -bination of developm ent and produc tion
expe rtise, M AH LE P ow ertrain has been
involved in o ver 30 significan t program s
for new engine con cepts over the p ast few
years in the autom otive, m arine, aviation,
m otor racing an d industrial sectors. W e
invest continuously in research p rogram s
in o rder to secure our lead ing po sition in
autom ob ile techn ology. M AH L

M O TO R S P O R TS M O T
The Formula 1 season 2006 is set t o
s ta r t w i t h new r u les . Thei r a im is to
lower costs, increase safety, reduce
c i r cu i t t imes and boos t exc i t emen t .
The mos t impo r t an t change a f f ec t s the
dr ive units of t he racing cars. The FIA
has consequen t l y spec i f i ed the use o f
V8 engines with 2.4 l i ter displacement
an eno rmous cha l lenge fo r t he teamsand eng ine manu fac tu r e r s invo lved .
In other words, everyone has to star t
aga in f r om scr a t ch . And tha t means
a po ten t ia l sh i f t in the r e la t i ve
s t r eng ths o f t he Fo rmu la 1 teams. The
season star t in Bahrain looks set to
herald an excit ing Grand Pr ix 2006.
Power limits: The new V8 rule is a real
challenge
Ac cording to the new regulations , the
new ly d evelop ed 2.4 liter V8 engines have
a po w er of around only 740 H P instead
of 900 at a speed of m ore than 19,000
rpm . In co m parison to the previous drive
units that rep resents a po w er loss of
around 2 0 p ercent. At the sam e tim e, the
eng ine m ust reliably cop e w ith tw o racing
w eeken ds an d h ence a service life of up
to 1,500 km . In 20 08, this requirem ent w ill
even be three racing w eeken ds and around
2,200 km . An e norm ous challenge for
developm ent and production at M AH LE
M otorsports.
MAHLE Motorsports Formula for
success
M AH LE b ecam e involved in m otorsport
as early as the 1 93 0's a truly w inning
com bination: In 20 04, for exam ple 16 out
of a total 18 G rand Prix races w ere w onw ith M AH LE m otorsport com ponents. In
2005 M AH LE sup plied six of the ten team s
yet aga in both the driver's cha m pionship
and d esign eng ineer cham pionsh ip w ere
w on w ith M AH LE m otorsport com ponents.
An d in 2 006 , six of the eleven team s
op ted for the p erform anc e a nd reliability
of our com po nents: B M W Sa ube r, Ferrari,
M idland F1 R acing, Red Bu ll Ra cing,
R enau lt and Toyota.
M AH LE M otorsports has set about tackling
the rule ch ang es at any early stage, coo rdi-
nating develop m ents intensively w ith its
custom ers do w n to every detail. All core
processes for m otorsport are b rought to-
gether at our m otorsport plant in Fellbach.
Around 190 engineers, designers and pro-
du ction or qu ality specialists w ork he re in
close coo peration und er one roof w ith
one com m on o bjective: greater perform -
ance. The m otorspo rt com po nents provid-
ed m ust alw ays be d esigned to reduce
friction and w eight w hile retaining the
required d urab ility. The end effect: to further
enha nce the engine pow er. The exp erts at
M AH LE a re in con tinuo us con tact with our
custom ers, enab ling them to respond
rapidly and flexibly to the d em and ing re-
quirem ents. In this w ay, for exam ple, the
piston m ass could be reduced by 5% onaverage from 20 04 u ntil 20 05 d esp ite
increasing sp eeds and a d oub led runn ing
tim e. M AH LE is one of the d riving forces for
outstand ing m otorsport success a relia-
ble and com petent partner in pole position.
Bad Vibrations
In a Form ula 1 engine around 9 00 m oving
parts m ust tolerate an d survive sp eeds of
m ore than 1 9,000 rpm . M ore vibrations
occu r in the new V8 eng ine g eneration than
in a V 10 eng ine d ue to physical factors: The
other ignition seq uen ces a nd ignition gaps
lead to co m pletely altered vibration and
less b alanc ed m om ents of inertia. This
results in co nsiderably higher m ech anical
loads for the o verall system , w hich has a n
effect on the reliab ility and service life of the
drive units and the m ain co m po nents, such
as the pistons. O w ing to the low er speed
range w hich can be utilized and low er torques
of the V 8 en gine w ith a defined intake p ipe
length, a highe r full-load sha re results in
contrast to the V 10 eng ine in relation to a
com plete racing d istance o f around 1 0% .
This en tails high er piston tem peratures,
w hich in turn requires an op tim ization of the
piston cooling or the use of hea t-resistant
alloys.
A further o bjective is to redu ce eng ine vi-bration s to a tolerable leve l. Ea ch individu al
engine com ponent is com puted and ana-
lyzed in the sim ulation , while its behavior is
asc ertained w ithin the overall interplay. A
new spe cification o nly gets the go-ahead
for racing after extensive end urance runs
on dyn am om eters involving thousand s of
kilom eters. This is bec ause the ne w V8 en-
gines have to exhibit the sam e stability as
their tried-and-tested prede cessors righ t
from the beginning, thus setting the highest
dem and s for the q uality of all com po nen ts.
No variable intake, exhaust and valve
controls allowed
A further crucial cha nge in the ne w set of
rules is the proh ibition of variab le air intake
system s w hich w ere previously used for
optim izing the torque and po w er. A m ore
narrow speed range is now available ow ing
to the fixed pa ssage lengths. Th erefore, this
calls for a com prom ise betwe en m axim um
po w er and go od drivab ility. B esides the
variab le a ir intake system s, variab le
exhaust system s as w ell as valve controls
are prohibited. In the sam e w ay, a long list
of exotic m aterials have been ruled out
the regulation s stipu late co nve ntion al tita-
nium and alum inum alloys for connec ting
rods, valves an d p istons.
O ne thing is clear: Th e co nce
from V1 0 to V8 entails eno rm
fort and exp ense, not only in t
also the entire veh icle.

As a leading manufacturer of light-
weight pistons for gasoline engines,
MAHLE has constantly redefined thelimits of performance through continu-
ous development and innovative con-
cepts. With the rising price of fuel
making efficient engines ever more
attractive, MAHLE can now offer its
customers an even more economical
solution for engines thanks to its pat-
ented ECOFORM piston. This makes
the ECOFORM piston superior to con-
ventional pistons in terms of mass and
performance. When combined with
other refined engine components, the
reciprocating masses of the engine are
reduced.
Continuous development in production
C ontinuo us de velopm ent and o ptim ization
is the ke y to techn ical advancem ent for anyproduct and com pany. M AH LE is renow ned
throughout the w orld for setting the p ace o f
inno vative piston d evelopm ent. O ne of the
latest developm ents in reduc ing the m ass
in its pistons for ligh tweight ga soline en-
gines, the EC O FO RM piston, has already
been launched on the m arket.
The ECO FORM piston is sim ilar to con-
ven tion al alum inum alloy pistons. B oth
have the sam e m aterial w hile the casting
m olds are also sim ilar. H ow ever, im prove-
m ents in the casting p rocess a nd m old
design have ena bled a significan t reduction
in the m ass by up to 20% w ith the EC O -
FORM piston.
The difference s in the m old design affect
the d em olding process. In co nventiona l
pistons, the s ide co re is released by
straight pulling of the core aw ay from the
cast piston (see figu re 1). Th is casting pro-
cess prevents ring belt undercuts in the
direction of the p in an d restricts the design
of the skirt area. Th e box w alls are parallelor sym m etrical to the p iston ce nter axis
(see figu re 2).
In the ECO FO RM process, the w indo w
insert rotates o n a pin as the p in c ore is
pu lled straigh t ou t of the m old (see figu re
3). Th is en ables u ndercuts of the piston
ring grooves. This ne w casting m ethod
offers design en gineers new op po rtunities
for w eight reduction . A large p ocket in the
balcon y in the direction of the bo lt reduce s
the m ass o f the p iston, w hile the sha pe
can be ch anged to m eet the design and
perform ance requ irem ents of the cu stom er.
Instead of the ed ge o f the w indo w being
pa rallel to the centerline as in con ven tion al
piston s, it is obliqu e an d rou nd in sh ape
w ith the EC O FO RM piston. The d istance
from the ce nter of the piston is large r at the
bo ttom of the skirt than at the top; this
gives the skirt a be ll-like shap e. The com bi-
nation of chang e in the window shap e and
inclination of the w indow w all provide a
redu ction of abou t 19% in the su rface area
of the skirt.
The inner core needs to b e cha nged in or-
der to m atch the w indo w incline. The inner
shape d esign can b e adap ted w ith repo -
sitioned w indow w alls, w hich reduces the
w eight of the p iston. By m aintaining a co n-
stant w all thickn ess, the inne r core follow s
the curvature of the rounded w ind ow . This
ad ds stiffness to the skirt. Th e use o f a sin-
gle piece inner core can then be a n op tion.
A draft is no t need ed since over ha lf of the
surface area that w ould ne ed to be d rafted
in co nve ntional pistons is already ang led .
As described above, the EC O FO RM piston
and con ven tion al pistons a re visually differ-
ent (see figure 4). The w eight of the E C O -
FORM piston is low er and is disting uished
by im proved d urab ility.
Continuous development in piston
performance
W ith the reduction of m ass an d running
surface in the sk irt area, the EC O FO RM
piston has enabled a red uction in friction
and hence an im provem ent in the running
condition. The results reco rded in the graph
below (see figu re 5) indicate the suc cess of

MAHLE has always been enhancing
innovative developments which are
more powerful than anything yet exist-
ing through research and development.
By thinking in systems and interrela-
tions and the optimized coordination of
all components, further performance
reserves can be mobilized. The piston
pin may be a small component but it
plays an important role for the perform-
ance of an engine. MAHLE piston pins
excel through utmost quality, precision
and application variety. The product
portfolio comprises diameters from 6
to 250 mm. For the application in pas-
senger car engines, piston pins are form-
ed by MAHLE with the latest multiple-
stage molding presses thus achieving
innovative and complex molds for high-
er stress-resistance. The increasing
ignition pressures require a permanent
optimization of the piston pins stress
resistance. For highly stressed en-
gines, MAHLE has therefore developed
piston pins of case-hardened steels or
nitrided steels with PVD coating.
PVD Coated Piston Pin
Piston p ins m ust have a high fatigue resis-
tance as w ell as w ear and seizure resis-
tance d uring c ontact w ith the p iston an d
conn ecting rod. C ase-hardened steels and ,
in a sim ilar w ay, nitride d steels revea l opti-
m um prop erties for achieving these re-
qu irem ents. Nevertheless, bushings in the
bo res are often nec essary in o rder to
attain acceptab le tribo log ical cond ition s.
For bo th w eight and cost reduction, en-
gine m anufacturers pu rsue the aim of
sup erseding bushings. The resulting stress
con ditions and con tact partners often
m ake the use o f a coa ted p iston p in ne-
cessary. Furtherm ore, a po sitive influen ce
on the friction perform anc e is exp ected.

It is the cylinder head that makes the
engine intelligent. Although there is
nothing exclusive about this state-
ment, the complexity of the assembly
is beyond doubt a complexity which
has increased in recent years due to
extensive measures aimed at greater
flexibility in sub-systems for carbure-
tion and charge exchange for instance.
The performance characteristics of a
combustion engine, its fuel consump-
tion and raw emissions are determined
by charge exchange, carburetion and
combustion performance parameters
and, more so than ever, by the cylinder
head and its adjoining components. Atthe same time, the cylinder head com-
plete system plays a crucial role in
determining the manufacturing costs
of the complete engine, as this essen-
tially defines the engine concept.
Cost-effective series solutions in the
sense of an intelligent simplicity
require a uniform and simultaneous
development for this, owing to the di-
verse and reciprocal dependencies
between the individual systems in re-
lation to the combustion process.
In response to this, M AH LE p ursues a
m od ular approac h in con junc tion w ith
cylind er hea d refinem ent, and is ab le to
develop and produce cylinder head m od-
ules itself. The p roven c om petence o f its

MAHLE crankcase ventilation systems
are reliably cleaning the oil-loaded
gases out of the crankcase. Thus, oil
consumption can be decreased further
and emission limits are fulfilled. The
oil mist separator, integrated into the
crankcase ventilation, separates the
aerial from the liquid elements. The
extracted oil is newly integrated into
the oil circulation and the purified air
into the intake system. The quality ofthe oil mist separator has direct
influence on the combustion and the
oil consumption of the engine. Oil mist
separators steadily gain importance
due to the pollution during changing
operating conditions of premium com-
ponents such as mass-airflow sensor,
turbo charger, charged air cooler or
exhaust sensor.
Oil mist separator and pressure
regulation
For gasoline a nd diesel eng ines, pressu re
in the crankcase is lim ited b y ventilation
using spring-load ed valves either regulat-
ing the pressure or lim iting the flow rate.
The valves are developed at M AH LE and
are designed as either m em brane or
throttle valves integ rated in the ven tilation
system . D ifferent separators can be a p-
plied to sep arate the oil m ist from the ga sflow . The sep arator is cho sen w ith resp ect
to requirem ents such a s the nece ssary
sep aration rate an d p erm issible pressure
drop , the existing installation space as w ell
as costs and m aintenance requirem ents.

What purpose does crankcase
ventilation with oil mist separation
serve?
D uring the c om bustion process o f a piston
eng ine, gase s w ill alw ays p ass by pistons
and rings into the crankcase. Du e to high
tem peratures and high p ressure differen-
ces betw een the com bustion cham ber and
crankc ase, the o il adhering at the piston
is carried along and dispersed into fine oil
m ist.
For environm ental reaso ns, it is not accept-
ab le to em it the engine ventilation into the
atm osp here. Instead, the b low -by gases
are clean ed of the oil m ist and returned to
the com bustion proce ss. This gives rise to
two tasks. The resulting overpressure in
the crankcase m ust be discharged to a
defined vacu um level using a ventilation.
In add ition to this, the ven tilation m ust be
clean ed of the oil droplets by sep aration.
The q uality of the oil m ist separation has
a significan t im pac t on the em ission b eha v-
ior of an eng ine and crankc ase ventilation
is thus of increasing im po rtanc e w ithin
engine developm ent.
Separation mechanisms and their
implementation
M AH LE u ses inertia-driven sep arators,
developed either as a passive o r as an
active system . Am on g the passive inertia-
driven sep arators a re sp irals, im pactors
and cyclones. Base d o n a sim ple con struc-
tion princ iple, they a re resistant to d irt,
m aintenance-free an d ac hieve a g ood to
very goo d separation perform ance . In the
case of a passive system w ith very highsep aration requirem ents, additional fiber
filter elem ents ca n b e u sed follow ing the
inertia-driven sep arator. Am ong the ac tive
system s are driven c entrifug es, such a s
the plate separator which co m bines low
pressure drop w ith outstand ing se pa ration
perform anc e. Inside the en gine, sep aration
system s are also c om bined , e. g. w ith the
cam shaft.
M AH LE integrates crankcase ventilation
system s in valve co vers or oil m od ules. This
results in integrative com po nen ts w hich save
costs and installation spa ce. The se ha vebeen developed at M AH LE w ith respect to
future requ irem ents regarding ventilation ,

Direct injection opens up new oppor-
tunities for supercharging in gasoline
engines, as downsizing really comes
into its own in conjunction with high-
pressure charging. The combination of
direct injection and supercharging is
today's prior art in diesel engines. It is
this development in particular which
has paved the way for advances in the
specific power and torque of low fuel-
consumption, auto-ignition systems
and played a crucial role in the diesel
boom of the last few years.
Th e introd uction of direct injection in gas-
oline e ngines creates new op po rtunitiesfor sup ercharging in these eng ines as w ell.
Som e of the d raw backs in supercharged
m ulti-point injection e ngines a re now com -
pensated for w ith direct injection. Ab ove
all, the vap orization of the fuel within the
com bustion cham ber plays a significant
role in coo ling the co m bu stion p rocess.
The lim it tem perature w as also increased
further thanks to advance s in the m ateri-
als for turbocharge rs. As a result, the fuel/
air m ixture no long er needs to b e g reased
to such an e xtent at higher load s. A sig-
nificant red uction in fuel co nsu m ption is
conseq uently ac hieved in real-life driving
m ode.
The torqu e is proportionally dep end ent on
the displacem ent and the break m ean
effective pressu re. Increasing the b reak
m ean effective p ressure m eans that the
displacem ent can also be redu ced w ith-out ad versely affecting the en gine perform -
anc e. In o ther wo rds, dow nsizing entails
increasing the p ow er and torque p erform -
anc e of sm aller engines so that they can
replace larger eng ines. Th ese e ng ines
have the follow ing a dva ntage: sm aller en-
gines w ith less displacem ent (possibly w ith
less cylinders) consequently w ork in m ore
effective op erating po ints, w hile e xhibiting
less losse s through friction and cha rge
exchan ge, accom pan ied b y im proved effi-
cienc y. This red uce s the fuel consum ption
yet furthe r.
N evertheless, m any cha lleng es still rem ain
as regards d ow nsizing . In particular, the
increase d therm al and m ech anical stresses
as w ell as kno cking tende ncies in the com -
bustion p rocess create problem s. Thu s, for
instance, the respo nse p erform ance of
dow nsized turbo eng ines d uring acce lerationfrom low er speeds is m uch less effective
than in large r naturally-asp irated en gines.

8/12/2019 news letter from Mahle
12/12
MAHLE is represented in all key re-
gions of the automotive industry with
development activities as well as its
own technology centers. A further de-
velopment center in Shanghai/China is
set to open its doors on April 19, 2006.
This ensures that MAHLE is present
with technological expertise in one of
the most important growth regions of
the world. MAHLE Per f o rmancespoke
to Dr. Uwe Mohr, Director Research
and Advanced Engineering of MAHLE
International GmbH about the oppor-
tunities in China, as well as interna-
tional networking and regional anchor-
ing of our technological expertise in
the markets.
China a growth market. What tasks
will the new regional Headquarters
in Shanghai assume central researchand development projects as well?
The new regional H eadq uarters in S hang -
hai w ill com bine ce ntral functions for our
prod uction plants in C hina, for instance
developm ent, testing , laboratories, sa les,
hum an resources, IT a nd finances. W e sha ll
not have a research center there in the
sense of fund am ental research, as has
been incorrectly portrayed b y som e in the
m edia. O ur app roach is no t to transfer
core com petencies in the areas of resea rch
and predevelopm ent to C hina, but instead
to serve the loc al m arket w ith its specific
requ irem ents through a local developm ent
team . The develop m ent center is therefore
integrated w ithin the new region al H ead -
qua rters develop m ent functions such as
design, com putation, com po nent testing,
engine testing , electronics lab oratory, che-
m ical laboratory, m etallog raphy etc. being
loca ted h ere. In o ther w ords, all the func-
tions required to develop a p roduc t from
the blank shee t of pape r to testing in the
eng ine and , finally, approval by the custom -
er. W e ha ve R &D centers in S tuttgart, Nor-
tham pton, Detroit, So Pa ulo, Tokyo a ndshortly in S hang hai too. A nd only a few of
these are ac tually invo lved in p ure re-
search and prede velopm ent w ork.
What does the market in China call
for? How do you collaborate
with automobile manufacturers?
In g eneral, all the reg ion s have their ow n
requ irem ents. O ur aim is to fulfill them re-
giona lly as w ell, w ith reg ion al contacts and
close interaction betw een custom ers and
supp liers. The C hinese m arket dem ands
products at very low prices. The local ex-
hau st gas regu lations a re currently at the
level w e ha d se veral years ago. W hen it
com es to developm ent, autom obile m anu-
facturers in C hina tend to follow the tradi-
tion al rou te: The y w ill typically have the
com plete eng ine d eveloped by a Europe-
an e nginee ring service p rovider, and then
produce it in C hina.
Why is MAHLE going to Shanghai
then?
In the future, Ch ina w ill have its ow nautom otive ind ustry w ith self-sufficient
areas of developm ent. And w e can expect
this trend to continue at a fast pac e. W hat
is lacking for the tim e being, tho ug h, is
the expertise of a sup plier in the country,
w ho speaks the sam e language and can
be integrated sim ultaneously in the d evel-
opm ent process. W e have decided to
bu ild up a local developm ent cap acity just
w here the m arket need s it. If w e sup ply
our custom ers on site tod ay, that w ill give
us unrivalled op po rtun ities for establishing
lasting and viab le su pp lier relation s w ith
a h igh level of custom er loyalty. W e there-
fore attach c on side rable im po rtance to
project team s w ith sales peo ple an d d e-
velop ers w ho know the regional cond itions
in this m arket, w orking together effective-
ly w ithin a close ne twork. An d all this on
the ba sis of a standardized M AH LE p rod-
uct developm ent process, which is acce pt-
ed internationally and ensures perm ane nt
qu ality righ t from the start.
How extensive is the knowledge
transfer to China?W e alread y carry out production at seven
plants in C hina. Nu m erous com pan ies lim it
their activities in C hina to p rodu ction for
com petitive reason s. You can view this
from two sides. W e be lieve that a collabo-
ration b ased on the de velopm ent of tech-
nological com petence in the c ustom er's
ow n language enables an open dialog
and offers m ore op po rtunities on a long-
term basis. In S han ghai, we are prim arily
conce rned w ith cu stom er requirem ents
and developm ent over the n ext three tofive ye ars. To this en d, em ployees from
Shan ghai have received spe cial training on
our Product Lines in different regions over
a pe riod of 6 to 9 m onths. But one thing
is clear: Th e fundam ental exp ertise at
M AH LE rem ains at central locations w here
w e actually carry out fundam ental research
and custom er-indep ende nt predevelop-
m ent. There we w ork on tasks wh ose
sign ifican ce is trans-regional and lon g-
term , and d evelop products for the n ext
decade.
How does the international network-
ing of development centers work?
Through extensive p roject m anag em ent
w ith internation ally exp erienced p roject
m anag ers w ho are fam iliar w ith the unique
character of a coun try's culture an d c ustom -
ers, and w ho provide targeted im petus to
developm ent w ith p ow erful process tools
and the very best staff. Key priorities a re
defined together w ith the individu al devel-
op m ent centers in the regions, de term in-
ing w hich issue s requ ire greater attention.
In this w ay, w e can com bine o ur energies
and ach ieve synergy effects.
What advantages does MAHLE offer
the market with its structure?
W hen it com es to the interaction of com -
po nen ts and products, it is safe to say
that we en joy the m ost com prehensivesystem s exp ertise there is in the a rea of
com bustion en gines an d eng ine pe riph-
erals. That pu ts us in a very strong p osi-
tion for the future. To rem ain a hea d in re-
spect to costs, perform ance and w eight in
an increasingly com pe titive fie
zation, you need a firm grasp
relations. The m ore you un de
