This year with our 2011 Sportswagen TDI we've been getting 30-32 mpg in city driving (my wife commuting to work and shopping), 35-36 mpg in mixed driving (30% highway miles is typical when I use it for work), and 42-45 mpg on 200 mile+ trips with highway speed limits varying from 55 to 70 mph and a little city driving included. (If I drive 45 mph on a flat road the computer will read well over 50 mpg.)
 
With our '06 Jetta TDI, we've been getting 32-33 mpg, 38-40 mpg, and 44-46 mpg in the above described conditions. (It's fuel mileage has gradually improved every year so far.)
 
Both are equipped with DSG. Hills, winds, loads, traffic, and road conditions all have an effect on fuel mileage in the real world.
 
Given these two cars' performance, safety, ride, comfort, price, standard equipment, and reslae value, I can live with the fuel mileage of each. Claims of 50 mpg+ do not impress me, because that is not how, where, or why I drive.

Indeed the Taylor's proved the RANGE of the TDI, can be much greater as they knocked down 84 mpg + on a 2012 Passat TDI. Now I would hate to drive like they do to get it, but I think the point is that almost anyone can come close if they want.

I'm still monitoring friends' TDIs, and none of them have ever recorded 50 mpg. The 2011 Sportwagon is right on the estimate, and is getting 42 mpg overall in mixed suburban/highway driving. Highest they ever recorded was 47 for a long highway stretch at 65 mph on cruise control. The older Golf TDI that reports to me now and then seems about the same, or a bit less than the 2011 wagon.
 
My brother's Jetta TDI is right around 38-40, but he's up at altitude. He loves his car.

My range for the mark 5, ( MY 2009) is between 39 and 47 mpg. This was the start of the gen/model (higher torque 236 # ft, lower fuel mileage, epa 29/40) than the mark 4 (155# ft/epa 42/49 mpg), spoken about in MSG #4676.
 
While it is still capable of 50+ mpg, you have to drop both the revs and speeds to consistently get it. But then again those are some of the prices for: 300# increased, the DSG vs 6 speed M/T (far less RANGE), changing emissions standards and compliance (differing penalites), and 52% more # ft of torque.
 
The additional thing is that gassers designers have long been put on noticed that the need to optimize their systems (aka drive train) for the 65 mph speed limit (range of course is anywhere from 45 mph to 85 mph). Obviously there is a double wink wink going on here. One example of the "range" is some pats of the Texas interstate 80 mph and soon to be legislated 85 mph. GBT !! The most obvious one most folks care about is mpg. In that sense the small percentage and volume of diesels have long been there. In effect I have taken that for granted from a practical point of view for easily 218,000 diesel miles. Indeed three VW examples are optimized for 81 mph 2,200 rpm 6 gear, albeit DSG/ 5/6 speed M/T. Below that (optimization) mph you can really post good numbers as fho2008 did with the 50 mpg 70 mph.
 
I have one gasser that uses a 6 speed M/T to optimize. It has been criticized and draws praise in the same analysis for using a so called "dual gear" over drive type gearing. I am sure there are other examples, but I am not real familiar with the others.
 
The NHSTA's own accident and fatalities figures confirm that even with higher speed limits, more cars, drivers, mileage, trips, the figures posted are the LOWEST and safest ever since they started recording these things.

If you compare apples to apples, the EPA revised their standards so while older cars may be rated higher by the old standard, they may not be by the new one (Web site converts all old numbers to the new ones).
 
With an automatic the 2006 Jettas numbers went from 35/42 to 30/38. Some of the older models are even more efficient, but most still can't beat the best new diesels - Passat 30/43. (Excepton is the 2003 Jetta with a stick that got 35/44 converted, or 42/49 by the old standards)

#4686 of 4747 Fuel Pump problems in 2012 Jetta Sportwagen TDI? by opsmaster

Hi - I am currently doing some research into the 2012 Jetta Sportwagen TDI. Heard good things about the car, but no prior experience with diesel. I have come across a number of fuel pump failure and power loss stories related to the TDI. This makes me concerned. Does anyone know if the issue has been cleared up for 2012? Is it related to American diesel fuel or a product defect from VW? Thank you.

I have a 2012 Jetta TDI. Alot of my coworkers have older ones. We all get in the high 40s and mid 50s on the highway. My coworkers have over 150k on theirs (03, 05, 09, and 11). We are all getting around 40-46 around town (DC + Southern MD). I never believed it until I did it my self. My buddy and I are tryin to see who can get the best mpg. He has a Golf TDI. He is winning right now with 70k miles on the car. He is pulling 55.3 mpg on the Beltway. My best is 52.3 mpg on the highway with 1900 miles on the car.
 
Oh and I did not pay $25K for my 2012 Jetta TDI DSG, TDI Monster Mats, CarGo sytem, Lip Spoiler, and Exhaust Tips.

Thank you, it was a test drive, as I said wish TDI was available when I bought, it wasnt.
 
 Instant econ showed 50 mpg, pretty much flat in my part of IL, and cruise was on.

Oh we were talking about the Sportwagon at $25K ++, not the sedan.
 
Also we were talking about average MPG over a year's time, mixed city/hwy.

Very similiar vehicles, just offering my 2 cents.
