The new 1.8 litre turbocharged Alfa Romeo engine is now officially available in the 2010 Alfa Romeo 159 range, after being previewed to the public earlier this year at Geneva in March. The new model variant is called the Alfa Romeo 159 1750 TBi and is positioned between the 2.2 JTS and the 3.2 JTS.
The 1.8 litre (1,742cc) engine makes a peak torque of 320Nm from just 1,400rpm, and peak power of 200 PS is achieved between 4,750rpm and 5,500rpm. These are very impressive power stats as lots of power is made throughout a rather wide range (thanks to variable valve timing, turbocharging and direct injection).
I believe there’s some very good tuning potential here, at the expense of narrower powerbands as a trade-off. The variable valve timing is configured to set valve overlap times in a way (VVT is on both intake and exhaust) that helps spool up the KKK fixed geometry microcast steel turbocharger up faster. 0 to 100km/h takes 7.7 seconds.
Other than what’s described above, the engine has a few more tricks up its sleeve. The 9.5:1 compression pistons have flexible rings and use materials that are designed to reduce wear. The aluminium alloy cylinder head uses roller rocker arms to help reduce losses through sliding contact by up to 65% at 2,000rpm, compared to normal cylinder heads. In Malaysia, only the 2.2 JTS version is available as of now.

this one is cool. but i dont really like the way alfa offer it cars using the same engine but at diff prices.
lots of torque!
another fierce continental car, but for some reasons alpha romeo is never in my pick list.
finally….FIAT group has launched d 1.8 T in its engine
we will soon hv this 1.8 T in the award winning Fiat Bravo….
wth d 1.8T….it can easily hit 250bhp wth mild tune up
Audi A4 1.8T B9 will hv competition soon….
Thought it was some modded Waja when i scrolled down the page until i stopped the page and saw the front grille. Da-yummm!
Retire the 2.2 JTS. Bring this 1750T into Malaysia, price it RM190k, I swear I will buy one.
don't worry CCC…..it will come soon…possibly after all the 2.2 stocks run out…
lf the price is RIGHT(read Alfa can't afford to think they're somebody in Toyota-Honda -MB-BMW German-Japan mentality Malaysian). We're really need Naza style Peugeot pricing in order to restore this brand.
I am speechless when l test drove an Alfa 159 last couple of month: for a sub-RM180K it's a steal.
lmagine with the brilliant 1.8T engine! Perhaps Proton can do Naza here, anyone? Sime Darby pricing not smart enough as they have BMW under their common roof.
For me majority prospect need rather fairer learning curve before they can embarked on this full soul ltalian babe. After reliability, quality is near both Teutonic or Japan then premium pricing maybe acceptable.
Confusing? Not even Japanese Mazda6 with brilliant handling than Accord not well received by Japanese-fan. What a luxuriously overrated Toyota-Honda can enjoy?
I'll embrace Alfa once they're proven in term of reliability.
Theopillus Chin:
Try photoshoped 159 with BRERA :
1-Detached side mirrors
2-Brera front end air dam
It will look more gorgeous though cannibalized the coupe: but Brera still got sexy butt (they can loan for estate@sportwagon 159).
Let us know if you can do that.
Paul;
Do Alfa need Lotus to perfect their already decent handling? Just for food of thought.
it seems turbocharging is the rage these days for conti cars
1.8L with 320Nm torque from 1400RPM with a compression ratio of just 9.5? that is either extremely good or just "not-so-honest" figures.
Why is that surprising, considering it has a turbo and direct injection?
@karl: i'm totally agreed with you. Malaysia are too mean & narrow minded, only stick with TYT-HM-MB-BMW German Japan genre. They never give a damn to true Italia blood.
wah! the engine is BENZINA. jauhi diri anda dari zina.
Visited the showroom yesterday , they have limited stocks left so better wait for the new TBI next year . Superb design for the offerings and a far cry from my former 155 TS.
toycar said : thats y not on ur pick list because u dont even know how to spell alfa romeo also….idiot…
azrai said : attention!!! this is typical malaysian mindset…first of all azrai u r sooo damn stupid…the defination of benzina is oil not zina bodo…..
kenapa la bangang sgt ko nih…..
plizz dont paste stupid comment here…
The price of this car might be little higher than 2.2 but below than 200k…its still ok because audi a4 1.8 turbo is rm210+++…..if u compare apple to apple la..the performance anytime better than the audi….
paultan: i know, but currently putting out 320Nm@1400rpm from a 1.8L turbo engine with a 9.5 compression ratio is not possible. Maybe by 2010 they can do it, but i have my doubt. There will be a more significant lag (say compare with the EP6DTS engine). I say 280Nm@ 1600rpm with a 10.5 is more realistically achievable. With a 1.8L with 9.5 compression ratio and 320Nm, you would most probably be looking at about 2,000 ~ 2250rpm at best. But if we were to assume based on fiat bravo engines (with sport mode on 230Nm), it may be as high as 2500rpm and above.
