Title: 2.0 GT TDI v 2.0 GTI
Post by: stealthwolf on April 02, 2009, 07:42:05 pm
On the motorway yesterday evening, driving to meet with up with some mates.

Was cruising quite gently and got overtaken by this 2 litre diesel. Followed it round some corners, a bit of playful 'banter' but noticed I wasn't much faster than it and on the roads, we were both bumping up and down over the same places.

What are the differences between the GTI and GTTDI, other than engine?

Same suspension set up?
Same weight distribution?
Same gearbox?

Torque is the answer your looking for. the TDI's have bags of it especially when a remap is in the equation  :evilgrin:

you gotta stir the box sometimes to compete stealth or get a remap

Not sure what that means but I had to knock down a gear to overtake.

These days I do that anyway. I've learnt that flooring it in 6th to overtake places a lot of stress on the clutch.

I owned a mk5 140 TDI before I got the GTI (with a Polo GTI in between!) and it definately rides better than the GTI but doesn't handle noticably worse, maybe on a race track but I'm not in to the sort of thing anymore.
They do go very well with a re-map, and I would imagine the 170 goes very very well with a remap when the DPF lets you.  :happy2:

GTI has a much nicer interior though so you can stay smug!  :laugh:

SWMBO has a 2.0TDI 140 Jetta and although quick is no where near GTI quick in standard form. And as for an ED30, no comparison mate, and as for a re-mapped ED30  :grin: :grin:  :evilgrin:

GT Sport 170 would be a good match for a standard GTI in some situations with the extra talks (more gear changes mind  :wink:)

Yeah definitely. I'm pretty sure thats why the new GTD is going to be kept at around 170bhp.

I've driven a 170PS GT Sport TDi and the GTi.

To be honest, around town I couldnt tell the difference in acceleration and general power etc. Both cars seemed to burn away from roundabouts and junctions with ease. The diesel tended to wheel spin out of roundabouts - low down the rev range which I imagine was when the full force of the torque kicked in. But not a lot seemed to happen higher up the rev range. The diesel also felt a lot heavier on the front end. So much so that the steering felt like it was power-steered more to help combat the extra weight. In general it felt as if their was less response from the steering.

The GTi on the other hand would keep on pulling through the range and not give in like the diesel did. It was also just generally more fun to chuck into corners.

On a motorway though, I could see how the diesel would potentially surpise a GTi owner. But once you stirred the pudding (or in the case of us DSG folk - just smack the pedal to the floor) I'm sure the GTi would come out on top. Stock for stock ofcourse.

I believe it's also due to it having trouble putting the torque down. The 170PS GT Sport is bad as it is. Ask for one as a loan car next time your in for a service.

EDIT: I've just checked on parkers.co.uk and the 170PS GT Sport TDi runs 258lb/ft of torque. Same as an S3.

i most admit i would of said its got to be down to the torque  :smiley:

and i really agree with the round town driving and that the power does come in a big shovel full, low down  :driver:

With a remap i'm putting out 366 lb/ft in the GT 170. From 40mph the GTI finds it next to impossible to keep up. Good fun though  :laugh:

....I'm not wishing to offend anybody but remapping your brain rather than the car's ECU brain and hence using your shifts to always be in the optimum gear, is a far safer and more enjoyable way to drive. Also, relying on torque in low gears is both lazy and not great for your car in the longer term.

I bet you have fun putting that down to the ground in a FWD. Or not as the case maybe.

I actually find it grand for putting down the power. I find myself accelerating much more progressively with the power. No need to be hard on the throttle at all. You can frighten people when you do put the boot down though :grin:
