All New Saab 9-5 Sed an:

Less Is More with All Turbo Eng ine Line-up

Responsible pe rformanc e with e ffic ient four-c ylinder turbo eng ines CO2 va lues from just 139 g/ km Three fue l types: ga soline, E85 and d iesel in all-turbo line-up

The a ll new 9-5s a ll-turbo p ow ertrain line-up b rings together Saab expertise in

turbocharging with state-of-the-art engine technologies.

With g asoline and BioPow er (E85 c om pa tib le) e ngines develop ing more tha n 100 hpper liter, the new 9-5 Sed an a lso a dvanc es Saab s rightsizing p ow ertrain strate gy. Tha tme ans efficient turbocha rge d eng ines as sma ll as 1.6 liters c an make a fitting p artner

for Saab s new premium sed an. With d iesel po we r, CO2 emissions as low as 139 g / km

are a lso on of fer. All transmissions are six-spee d .

Gasoline choiceAll eng ines fea ture elec tronic ma nage me nt, elec tronic throttle control, d irec t ignition

and four valves pe r cylinder op era ted by o verhead, maintenanc e-free , cha in-d riven

c amshafts. For long evity and reliab ility, turboc harge rs are w ater-c oo led and use a ir-

to-a ir interco oling to inc rea se intake c harge density.

To g ive m inima l p iston fric tion and we ar c harac teristics, while a lso b ene fiting fue l and

oil c onsump tion, the c ylinder wa lls of the e ngines a re laser-etc hed for an extremely

smo oth finish. Und er-skirt p iston o il c oo ling and sod ium-filled exhaust va lves a re further

efficiency measures.

1.6 TurboThe eng ine line-up sta rts with this pow erful four-cylinder motor giving 180 hp / 132 kW

and exce llent torque of 230 Nm a ll the way from 2,200 rpm to 5,500 rpm. It inc lude s an

ove rboost func tion, which ra ises torque to 266 Nm for up to five sec ond s on a wideop en throttle.

Rated amo ng the mo st p ow erful series p rod uc tion engines in its displac ement c lass,

this rightsized pow ertra in gives the a ll new 9-5 strong performa nc e: zero to 100 kph in

9.5sec ond s, and impressive fuel consump tion a nd CO 2 em issions p rojec ted to b e 7.6l/ 100 km a nd 179 g/ km.

For streng th a nd red uc ed noise, the c ylinder b loc k is in ca st iron. A die c ast, structural

a luminum o il pan a dds further stiffness and noise suppression. Add itiona l refinem ents

inc lude the use of ho llow c am shafts, for red uced weight and lower rec iproca ting

ma ss, and a dual-mass flywheel for imp roved running refinement. A map-based

thermosta t c ontrol raises the c oo lant temperature at low engine speeds, or under

light loa ds, to help red uc e interna l lubricant fric tion and a lso imp rove fuelconsumption.

2.0 Turbo Gasoline a nd BioPowerThe performa nc e sta kes a re raised with this a ll-aluminum eng ine,which is also

ava ilab le in BioPow er spec ifica tion, ena bling it to run on g asoline a nd/ or E85 fuel (85%bioetha nol, 15% gasoline) in a ny b lend s. In b oth c onfigura tions, it d elivers pea k po werof 220 hp/ 162 kW and p lentiful torque of 350 Nm from just 2,500 rpm.

This eng ine is offe red with f ront w hee l drive or Saab XWD, the industry-lead ing a ll-

whe el-drive system . It fea tures va riable va lve t iming and d irec t injec tion to furtherimp rove fuel c onsump tion, emissions and pe rformanc e. The camshafts have

hydraulic ally op erate d vane-type c am p hasers which a llow both the inlet a nd

exhaust va lve timing to b e a djusted indepe ndently, ac c ord ing to varying engine

spe ed and loa d. The m any be nefits include a b roa de r spread of to rque, higher

ma ximum p owe r and imp roved fuel c onsump tion.

Direc t injec tion delivers fuel unde r high pressure d irec tly into the c ombustion c ham ber

during the c om pression stroke. This ena bles the sep a ra tion o f a ir and fue l de livery,a llow ing improve d sc aveng ing o f the c ombustion cham be r to g ive substantially mo re

A tw in-sc roll turboc harger is a lso used , which virtua lly eliminate s turbo lag a t low

eng ine speeds and d elivers a thrott le response c om parab le to tha t of a na turally-

aspira ted eng ine. Eac h of the two sc rolls on the turbine is fed by a sep ara te exhaust

passage - one from c ylinders one and fo ur, the othe r from c ylinders two and three .

Othe r fea tures inc lude: twin c ounte r-rota ting b a lanc e shafts for smooth running; a

forged stee l c ranksha ft for added streng th and a luminum p istons to reduc erec ip roc a ting mass.

With front whee l drive , this eng ine p rop els the a ll new 9-5 from zero to 100 kph in 7.9

sec ond s, giving p rojected c omb ined fuel ec onom y of 8.4 l/ 100 km and CO 2 emissions

of 199 g / km.

2.8V6 TurboAva ilab le e xc lusively in Aero spec ifica tion with Saab XWD and a 6-speed autom atic

transmission, this eng ine ha s a c lassic 60 angle betwe en the c ylinder ba nks to g ive

op timum ba lance for vib ra tion-free running to ma tc h its silky powe r delivery. It d elivers

300 hp/ 221 kW and an impressive 400 Nm o f torque b etwe en 2,000 and 5,000 rpm,g iving zero to 100 kph ac c elerat ion in just 6.9 sec onds.

Variable valve timing on both intake and exhaust sides ensures a near linear delivery

of torque , irrespec tive of eng ine spe ed and loa d . The single, tw in-sc roll turboc harge r

is mounted c entrally above the transmission a nd fed by both ba nks of c ylinde rs. The

use of two inlet trac ts, one for ea c h c ylinder ba nk, sep ara tes the exhaust g as pulses,

imp roving g as flow , red uc ing energy losses and ra ising turboc harger efficienc y.

The e xhaust manifolds a re doub le-skinned w ith hydrofo rmed sta inless steel liners to

improve cold start emissions by minimizing heat absorption to the manifold. Air

achieve 'light off', its effective working temperature, as early as possible.

The strong , forged-steel c rankshaft runs in four ma in bearings and the steelc onnec ting rod s a re sinter forged for extra streng th a nd durab ility. The polymer-

c oa ted , aluminum p istons and the floa ting wrist-pins are c oo led and further

lubric a ted by trip le und er-skirt o il jets.

Diesel Choic eBoth 16-valve, 2.0 liter turbo d iesel engines have a c ast-iron c ylinder b lock with laser-etc hed c ylinder wa lls and a n aluminum a lloy cylinder hea d . The tw in overhead

c amshafts a re c hain driven a nd ma intenanc e-free . The engines also fea ture

electronic ma nag ement, common rail, direc t and multiple fuel injec tion, a w eight-

saving p lastic intake ma nifold and a dual-mass flywheel for grea ter running

refinem ent. Ma intena nc e-free exhaust pa rticula te filters to mee t Euro 5 em issionsreq uirements a re fitted as standard.

2.0 TiDThe 16-valve, 2.0 liter turbo d iesel engine deve lops 160 hp (118 kW) and 350 Nm o f

torque a nd o ffers projec ted CO2 emissions of just 139 g/ km, to gethe r with imp ressive

fuel economy of just 5.3 l/ 100 km over the c ombined c yc le. It has a va riab le g eome try

turboc harge r for exce llent low -end response.

2.0 TTiDThe mo re pow erful two-sta ge turbo version delivers 190 hp/ 140 kW, and 400 Nm o f

to rque from just 1,750 rpm for excep tiona l pulling pow er. It g ives zero to 100 km/ h

ac c elera tion in less than 9 sec ond s, togethe r with projec ted fuel economy o f 6.0 l/ 100

km and 159 g/ km CO2 em issions. It will be a va ilab le with both front whee l d rive a nd

Saab XWD.

The series seq uentia l two -sta ge system uses two turbo c ha rgers of d ifferent sizes with

by-pass va lves tha t d irec t the exhaust gas strea m b etw een the two turb ines. At low

eng ine spe ed s, the sma ll turboc harge r supp lies boo st p ressure inde pend ent of eng ine

loa d . At intermedia te engine speeds unde r highe r loa ds, both the sma ll and large

turboc harge rs provide b oost p ressure; while a t high engine speed and loa d , only the

large turboc harger is enga ged .

This arrangement p rovides the d river with the best o f b oth wo rlds : go od , instant

torque a t low engine speeds - via the low-inertia sma ll turbo -and strong , top -end

po wer at higher engine speed s when the large turbo is enga ged.
