VAG 1.9 tdi v. 1.6 cr tdi

Bif

Folks,
Is anybody in a positon to compare both these engines having driven them in the same model? i.e. a direct comparision between a golf with 1.9 versus 1.6? Thanks in advance.

The 1.6TDi doesnt have as much pull as the older 1.9TDi. It has more or less the same bhp, but doesnt feel as quick.

Remember that if you want the 1.9, you'll have to buy second hand, and if you want the 1.6 you'll have to buy new.

Thanks for the reply. I was really thinking of it in terms of an Octavia which is available in both for the much the same money. My only experince is the 2.0 170 in PD and CR. In that comparison the PD felt much "punchier".

I've driven the new 1.6Tdi engine in an Octavia and it was pretty poor. Absolutley nothing going on until around 2,000 rpm where the turbo comes in.

1.9Tdi is no great shakes either, but at least it has a bit of useable torque before the turbo comes on line.

2.0Tdi Bluemotion 110 was better than both so I'm not sure why that's been discontinued.

You'd be a fool to buy a new Octavia with that old tractor 1.9 engine. The modern 1.6 common rail has very similar (just adequate) performance but emits only 119g/km of CO2, which is one of the reasons why it will make it a lot cheaper to own.

Is the 1.6 any more refined? I'd hope so.

What about adding a red i on the badge? That and a remap would surely make is a Ferrari beater, and caoable of 87mpg

It is indeed. Very quiet and smooth for a Diesel engine, I just nearly got creamed on a roundabout trying to take off from low speed in second. Ended up doing the karting thing of jumping forward in my seat to try and get a bit more acceleration :rolleyes:

well there's the prob right there dont take off in second gear particularly in a diesel

If I'm still moving, I'm not going to shift back to first. It's a roundabout I take a good few times a day, in a a good few different cars.

Just like the 1.9 tdi infact

I'd actually take the 1.9. Fair enough it's a bit rough, but it'd be better for towing and overtaking, it's tunable and less of a risk reliability wise.

Why would it be better for towing and overtaking? Max torque and max power are the same in both cars and max torque is available at the same revs in both cars. Acceleration figures are identical in both cars too (no surprise there after my previous sentence )

Tax is higher (so trade-in values will suffer badly in the future), the technology is obsolete (abandoned by VAG - they now prefer to pay others for their technology rather than use their own), it is noisy and unrefined.

Taking off from low speed in second is fine on most occasions, but if there is any chance at all you will need to use more than pedestrian acceleration, you should go back to first. I do appreciate though that you drive a lot of different cars with all different driving characteristics, but I feel my rule there is valid for all occasions.

The road tax for the 1.9 is €156 a year and it will avg about 55mpg no matter what way you drive it.
I doubt if saving €50 euro a year on road tax would be dealbreaker for most.

VRT is also co2 based.

Figures quoted are peak figures, I get the feeling the 1.9 has a better power curve.

Yeah, me too. I cant imagine what the 90bhp 1.6 will be like in the golf, or the 105 in the passat for that reason!

As harsh as we're being about the engine in comparison to the 1.9, its probably no less lively than the 110bhp PSA/Ford 1.6 diesel engine

R.O.R, tis a shame alright about the 2.0 110bhp, for the octavia that would have suited much better indeed, and it goes without saying for the passat too.It aint out of production though, the new Skoda Yeti has it:)

Yep they're peak but that's at 1900rpm iirc. That's so low as to make the torque curve below that pretty much irrelevant tbh. And I'm not even talking towing yet

Having checked the figures from Skoda, that's what I was hoping for too, but in practice it's far from the truth.

To be fair though, it was a brand new car with 11km on the clock and quite often diesels are a bit tight at that stage. Hopefully with a few more miles on the clock it won't be quite so bad, but for what will be the big selling engine I'm hesitant to recommend it to anyone.

It's not nice to have to rev up and nearly slip the clutch on a small diesel just so it won't cut out. the nice thing about the old 1.9 is that there is plenty torque available below 1900rpm.
