1.8T VS 1.4 Twincharged

[Petrina Polo]

Hi,

We are expecting to have the 1.4 Twincharged motor in the new Polo Gti.

Has anyone driven this drivetrain maybe in the Golf V GT?

How does it compare against the 1.8T from the Polo Gti?

Will anyone be changing over their Polo Gti's for the new model?

[astro]

what mods would be avialible? and will there be a dramatic decrease in the power out put? i am sure it will be better in the polo cause it is alot lighter then the golf. what are the pros and cons? how long till its hear? price increase also?

[tinto]

read the TSI v TDI thread in the Golf mk5 section.
I usually end up ranting about the how awesome the 1.4TSI is, but i'll hold back this time.

It will be a perfect engine in the new Polo.
Immediately tunable to over 200hp with the APR/Oettinger flash alone.

I don't have a comparison to the 1.8T, but that's a much more established engine, so has many more current tuning options for big power.
But I can't imagine the 1.4 aftermarket sitting still for long though... since the engine is going to be in Golfs, Polos (and I believe a few Audis too).
The engine doesn't attract a premium price in the Golf, so it shouldn't in the Polo.

[Greg Roles]

...it's a smart move for VW, putting the smallest "hot" engine into the Polo, whilst still giving a great power output, wouldn't it be lighter??

[Veee1.8t]

im still contemplating trading it in for the new model either polo gti or golf gti, i have people telling me its smarter to trade in and upgrade and some people telling me to just pay the rest of the car off and keep it till it breaks...so i dunno...what are some of you going to be doing?

[Chuck]

im keeping my current one til the wheels fall off it!

[jkristo]

Yes I agree, however while I do love my current GTI...it might be hard to resist the new one...offering a DSG version will probably seal the deal for me...right now tossing up whether to tune my current 07 GTI or start saving for a release fingers crossed late next year...

[pixl]

I'm leaning towards upgrading, but only if the ride is more fun. Time will tell, I guess.

[Petrina Polo]

I cant see it being better than the 1.8T. Maybe an equivalent at best..

The Golf GTi didnt ditch the 2.0T for it so I dont think it will have the tuning potential some think..

I think it might have the low end superior to the 1.8T but I cant see it having more top end....

I will go test drive a Golf GT with the 1.4 and report back, also an unmodified Polo Gti. I encourage others to do the same for a more rounded view.

[DeanB]

I'm happy with what I have and one of the reasons was the ability to play with a "sorted" engine with a variety of companies offering options (ie ECU).

In the short-mid term I won't be jumping to the new one. Maybe, in a few years when upgrade paths are well worn and any mistakes with mods are all sorted :)

[JIMTRON]

I have driven a friends stock '07 golf gt sport. The 1.4 is a very impressive engine, great for it's size. It pulls hard all the way from low revs, smoothly too. Just doesn't have the same torquey feeling as the 1.8T though, like you're being pulled by a steam train.
I much prefer the look of ours over the new one as well, especially the front.

[jkristo]

Also considering getting an Amorak...

[xtturbo]

I've driven the 1.4 Twincharge.

The engine itself is pretty cool, it sounds awesome and its got plenty of go... that said... I'd take a 1.8t over one any day... 1.8t is a much more serious motor.

[philthy]

There's no replacement for displacement my friend. :)

1.8 will always be more powerful

[POwers]

hopefully it brings the price of the current GTI down as I am in the market for one :D

[noone]

Get Flapps, its had a lot of work done, if I hadn't just spent a bit on mine, would buy his in a flash...

Its in the Classifieds section.

[mozzzy_2000]

I was just reading APR does a chip flash for this engine in the Golf GT and they're claiming around 151Kw & 317nm of torque which is inline with the APR 1.8T stage one. However I am not sure how much more can be pumped out of the engine after that.

[astro]

Thats what i am thinking aswell i thought the 1.8 will always be better.

[KWICKS]

I am a fan of the Golf GT 1.4 TSI. Around town the off idle response is awesome, and the fuel economy very good as well. We would have one in the driveway today if they could have delivered it, instead we got an available GTI Golf. In the lighter Polo shell I imagine it would be very rapid.

[nomodlowkmgti]

I would update to get the dsg auto and a 5 door gti would be great .I think the performance will be good with 1.4tsi after all new polo is a bit lighter in weight in the new model
so i am expecting a good 0/100 time i hope to see some new vw stuff like adaptive cruise ,park assist ,reverse camera ,adaptive chassis control that has auto shocks and settings of comfort normal or sports.I think i would not go for the golf because i like the polo size and if i can get some of its features and save some cash it would be hard not to update nxt year.

Hi!

Who will buy Golf VI then? It is virtually impossible to get all these gadgets in a Polo. Polo should be simpler and smaller...

[Petrina Polo]

I might do a backflip here...

Maybe the 1.4 twincharged motor with DSG auto will keep it ahead of the 1.8T

Even if the 1.4 doesnt have the dizzy heights of the 1.8T motor the DSG box will keep it on boost all day long. Off the mark it will move as boost can be loaded up on a stall and no loss of boost through gear changes..

I say this in consideration with XR6T... The auto guys will 300rwkw were running mid 11s, the manual guys with 330rwkw were lucky to run 12.5. having dump boost through changes was killing them.

[GoLfMan]

why the hell would you want a 1.4 car over a 1.8t 20v.

the 20v has been around for yonks with plenty of power upgrades that are tried and trued.

your taking a step back by decreasing capacity, and going to a relatively unknown quanitity of an engine!

cut the crap. Get a big turbo upgrade (GT28RS+) forged internals and enjoy the dam thing!

that would be the best result.. :biggrin:

[kevvie]

Does anyone know for sure that a new Polo GTi will be available in Australia ???

Amen!:bowdown:

[Chipped]

No I spoke to my VW dealer recently...he said the plans to introduce the Sirocco were shelved and that with VW he reckons nothing is for certain - he also said as a dealer they won't have any news until a week or two before the news is to be actioned...hmmmmmmm!!!

[Gti Dave]

Really hoping the new Polo Gti will come in 5 door guise with the 1.4TSI twincharged engine with DSG. Most likely would be buying that for the wife particularly for the availability of engine tuning options with APR. Recently bought the new Ford Fiesta Zetec for the wife and so far so good but the only real complaint is a lack of power. Hence the new polo would be a great changeover. Personally if our budget could stretch to the new Golf Gti then I'd prefer that. Otherwise, the Polo should be good.

For that exact reason. The 1.8T 20V is an old engine. There have been lots of refinements and advances made in the 10 to 15 years since this engine was originally made. Yes, the 1.4TSI is new, but there is a lot of excitement and demand for updates, and as one person has already indicated, ECU updates upgrade the power in line with the 1.8T's ECU updates... I'm sure other power options with follow.

All things being equal, there is no replacement for displacement... but 10 to 15 years of development in the 1.4TSI over the 1.8T 20V means all things aren't equal here.

I'm with you Dave, if the new 1 comes in 5 door it is likely I'll buy another as my kids will need wheels in a few years and what better way to start than with a Polo GTI.

1.4TSI are also OK for P platers I believe and is it will be least powerful car in the family will allow that route to bypass the P requirements as well.:eek:

To be honest though, I'd rather have the 1.8TSI of the A3 in the next Polo GTI than the 1.4TSI ...... :confused:

[Gambit]

well if the rumours are true about VW scrapping the 1.4TSI engine, then don't be surprised to see a 1.8lt TSI with a twinscroll turbocharger onboard, with integrated wastegate control, billet compressor wheel etc etc. Check out BorgWarner EFR range of turbos.

[Mystic storm]

Lol scrapping it already...!!

[flat6]

rumor i heard was they were scrapping the 3.2L engine from the R32, never heard anything about the 1.4 being scrapped?

I would highly doubt it the way things are going.

[Gambit]

I read it here:
Volkswagen 1.4TSI twincharger to be phased out: report | Car Advice | Reviews (http://www.caradvice.com.au/99056/volkswagen-1-4tsi-twincharger-to-be-phased-out-report/)

[flat6]

Will be interesting to see if they do go ahead with it, typical i guess considering it probably costs twice as much to build as a 1.8t.. They did that with the mk6 golf, its design was cheaper to make than the mk5, automakers scrimping at every angle.

[pologti18t]

I think a 1.6L turbo engine would probably replace it.

APR have dyno'd a new 1.4TSI Polo GTI.... 115kw at the wheels!

[CNBLU]

is that stock or with a tune?

[pologti18t]

Stock tune

[seangti]

perhaps i'm being cynical but I read that and wonder about the long term durability of the 1.4tsi. Does VW know something else apart from immediate cost to build. The old 1.8t may lack sme character (in polo form anyway) but it's well proven.

the old 1.8T is obsolete and wont pass future emission standards. It's history.

[noone]

In which country? UK standards seem to be higher.

[pologti18t]

Euro standards. VW don't build that engine (1.8 20V) anymore as far as I am aware.
It was an old design that was pensioned off.

[Big Yellow]

they're still used in the B8 A4s here

[pologti18t]

Actually i think you will find its a 1.8L version of the 2L GTI engine. Direct injection and 16V.

Correct. :)

[brad]

That's the EA888. Same as a Skoda Octavia engine. Craps all over the old 1.8 5 valver.
