opionions please.. jetta wagon TDI vs Gasser

[nostatic]

Am closing in on 30K miles with a 2011 JSW TDI DSG (xyz). Great car - zero complaints.

[intakexhaust]

Something else to consider in the small diesel market is the soon to be released 2014 Mazda 6 w/ 2.2. No reliability record to review but overall a neat package delivering 56 mpg (from reviews... not verified). Re-thinking the diesel design and emissions - lower compression, two-stage turbo, less after exhaust components, etc. Not sure what the price will be but the similar car but with gas engine has an approx. base of $21,000.

As an owner, I hear this from time to time. Usually it's someone making small talk at a filling station. "My friend has one and he says he gets 50mpg." It's not gonna happen in real world driving. Under optimal conditions in the flats and at 55 mph, maybe. Realistically, it's gonna be 41-43 mpg highway.

Disagree. Easy can get 50 mpg in flat terrain going 65-70. I averaged 42 mpg in daily commuting in LA. Half of it driving at freeway speeds, the other stop and go.

If I reset the MPG while driving 65 mph in my F250, it shows I'm getting 21-22 MPG. So, yeah it will do that in the flat, running on cruise control, already up to speed, etc.

But it will not average that!

Going pure hwy miles I think I've gotten as high as 45mpg. City is around 35, mixed somewhere in between depending on the details. I've only seen 50+mpg going downhill

You can say what you want but you are full of ****. I know what I'm speaking of and my son does as well.

[enzo1]

isn't the 2.5 getting replaced with the old 1.8 t but with 170hp?....

My real world experience aside, you're effectively saying VW is sandbagging their EPA ratings (42mpg for the JSW). Why would any manufacturer today do that?

Further, what would anyone stand to gain by saying the car that they personally own is worse on fuel than it is? I really wish it got 50mpg. I'd write it if it did. It simply doesn't.

There are tons of reputable reports of 40-43 mpg. I've never read one that said 50 real world mpg. I think there would be plenty of them if they existed, don't you?

And why are you being a dick?

[peppy]

This is from my 2001 TDI. I drive a mix of interstate highway and town, with some rural back roads.






The bottom one is the oldest, and it starts at 280,000 miles

[peppy]

I think we are off track here.

Widgeon13 is talking about a 1.9 TDI not the newer 2.0 TDI.

My charts above are for my 1.9 TDI, our 2.0 TDI does not get 50 mpg it averages around 45 mpg with the 6spd manual.

I think these care start to get good mileage around 100,000 miles. It seams they get a little better with more miles.

[pavulon]

That could be Peppy. A new sportwagen is heavier, w/ wider tires and (presumably) a bit more drag w/ DSG. Don't know about aerodynamic drag. In the end, it's an academic argument/conversation as anyone can write whatever and it doesn't change reality. They're all pretty nice cars and I think the TDI/DSG combo is pretty entertaining to drive as long as the HPFP remains intact...although some speculate that the HPFP problem is really a fueling issue.

To do it again, I'd want to drive a '14 w/2.0T and TDI back-to-back. I hope the '14's keep the JSW's true indep. rear suspension. Somehow, that seems more elegant than a beam.

ahh... many good posts, with a tiny bit of hate and discontent..

I commute 600 miles a week, and I go to Arizona ever other month,

I'm thinking diesel is the way to go

and I plan on keeping the car for at least 10 years

No-brainer then. I commued about that distance for almost a year in my TDI and it sure was nice to only fill up once a week to the tune of $50.

And one last comment on the money opportunity cost ... I get .75% on my savings right now, so I'd rather have those $5k work towards my gas bill.

I get 47 mpg over the last 40,000 miles on my 2001. And I drive my car fairly hard, and at 75 mph.

[Deschodt]

AS luck would have it, I turned in my Audi for service and got a jetta 2.5 loaner... There is not a single redeeming quality to the 2.5 engine. It's noisy and gutless, and it makes the Tdi seem like a piece of jewelry in comparison...

great...but I think the differences between A4 and A5 TDI mpg was covered.

That's in the UK

1 imperial gallon = 1.2 US gallon

So 65 mpg imp = 54 mpg US

Ah, makes sense now. Thanks! Is 54 what we expect from the diesels in the US? I didn't see anything that high.
