Jetta - FSI or TDI?

[platzie]

The VW Austral dealer at Newstead said that, the guy had no idea about any of the cars and he was so full of **** his eyes were brown so i dunno if thats the truth or not. Yeah i'll be sure to give JMac a bell if i do decide to get it.

I have a 2.0 FSI Jetta and love it,the motor is nippy enough,quiet,and economical,and the automatic transmission is a 6 speed unit,which is silky smooth.

I think any of the Jettas would make an ideal car,you are lucky to be getting something with all the luxury and safety equipment as standard.

Wowee that sounds promising! I'm liking the idea of 170kw

Don't just go looking at the power figure here. Dont be put off by the low power figures of the diesel. A TDI might not sound too exciting on paper with a Kw rating of only 104kw ( or 125kw in GT , Jetta models ) its the torque figure of over 350NM that makes that difference. My GT has been chipped to deliver about 150kw now but its has over 400NM of torque and in the real world no GTi ( which has more Kw than mine ) i've come across so far can keep up with me. Its a combination of power and torque that creates a fast car - not just power.

a high torque low power car can be just as fast as a high power low torque car.

I'd also look into insurance because most insurance companies dont frown upon a Turbo Diesel car as much as a Turbo Petrol car as thankfully for now they are not considered as a "hoon" car.

Why not test-drive both and see which you prefer - I was blown away by the performance of the diesel when I test drove my golf and would never consider a standard N/A petrol engine.

Yes maybe a stock GTI vs a chipped GT, but once you chip the gti then the gti will win for sure. An apr chip gives a GTI figures of 188kw and 411nm which is more torque and power then a chipped GT. In terms of power and out right pace, petrol turbo will always have that one up on a diesel turbo, for now anyway.

Hey guys,

I might be getting my hands on a Jetta relatively soon. However, due to the fact that i am a P plater i cannot drive the petrol turbo engine that i want. So i would have to settle with just the 2L FSI or the TDI. I was just wondering, because the diesel is turbocharged, are there easy tuning capabilities for it? Or do people generally not bother with tuning a diesel? If not, which would you choose, the FSI or the TDI?

Cheers,

Depending on your State in NSW and ACT we have special exemptions on the 1.4TSI motor because of its Size.. Weird loop hole but Volkswagen Australia Pushed hard for it to be exempt check with the RTA in Queensland to check..

Ever heard of the Lemans 24hr?

I wasn't trying to say that a TDI is faster than a GTi or slower because he's not comparing the two, he's comparing a TDI with a standard FSI jetta and the point i was trying to get across is that a TDI ( even in stock mode ) is not far off the performance of a GTi and therefore more of a performance car than a Jetta FSI.

Yeah i called up the RTA in Queensland and asked if i was allowed to drive the 1.4TSI. They asked if it had a turbo or supercharger and i said yes (refrained from saying both because i think she would have assumed this meant it had massive power), as soon as i said yes she said well it doesnt appear in the list of exempt cars so you cannot drive it. I tried to explain to her that it had less than 100kw and she went off to ask her supervisor and she said all they asked was whether it had a turbo/supercharger and as soon as she said it did then they said i couldn't drive it. So i discussed the issue with her and she realised my view on it and told me to write a letter to QLD Transport to bring the issue to their attention (though, i believe they are already aware of this issue). Still waiting for a reply though, i think they are struggling to answer my final question of "if you cannot make this car exempt, please explain to me why a 90kw golf is deemed 'high powered' yet a 184kw golf is not?"

Maybe i miss understood you when you said:

Yes you did miss understand but I forgive you.

From one P plater to another, I wouldn't worry too much about tuning the car for performance, it's just not worth it. I could add a $1500 exhaust to my car and get another 10-15hp if I'm lucky. Comparitively, I had a ride in Shane's chipped Golf GTI last night and holy crap that thing is so fast, it was awesome. Now I'm just saving my money, it'd be an absolute waste to go and burn it trying to add power as a P plater.

I also went in Maca's TDI Jetta, it has the Oetinger chip, and goes alright, so I'd probably choose that if I were you.

[platzie]

Oh no i wasn't going to bother tuning a naturally aspirated engine. I was more interested in seeing what kinds of power increases can be seen through tuning the ECU of a TDI. And then getting peoples opinions on what to get. Still unsure of what to get though, whether it be a Jetta, Golf, Passat, or Jaguar X-type.

...more power at this stage anyhow....

mmmm... yeah i reckon a chipped GT TDI will smash a chipped GTI.... up a steep mountain.

Hill Climb Challenge anyone?

Ive been considering a Golf for a while .. in TDI, FSI or GTI.. but Jetta seems like a good alternative.

Is the suspension in the Jetta TDI same as the Jetta FSI?
And how is the handling / fun to drive factor when compared to a Golf equivalent?
I don't know why, but Hatchbacks just "seem" to be better balanced and less awkward than the saloon version to drive aggressively? Maybe I'm just imagining it.
That is why I'm always wanted the Golf GTI, but they hold their value too well to be a "value" second hand buy.

I know i should just go drive to find out, but its soooooo hard to get a spirited drive and real feel for the car when the owner/dealer guy is next to you.
Its over to you guys

And one more question about TDIs...
What is it that makes it so slow on paper in a straight line? I thought torque is what counts.
With neck snapping 320nm and only a few kw less.... why is it slower than the FSI from 0-100?
What is the rev limit / power band like?

thanks

Probably turbo lag?

although the golf tdi i drove wasnt as nearly as bad as our 407 diesel.

The pugoets complete lack of respensiveness untill 2000 rpm then a sudden pull up till like the rev limiter at like 4500 makes for good fun though haha
